1.12	18-Sep-2001	ad	Beef up the stic X interface, and tighten a few screws here and there.
1.11	30-Jun-2001	tron	branches: 1.11.2; 1.11.4; Install "dev/tc/sfbreg.h" which is required for building the Alpha X11 server.
1.10	16-May-2001	ad	Put back /usr/include/dev/tc/sticreg.h.
1.9	11-Apr-2001	jdolecek	Put back all header files defining ioctls
1.8	11-Apr-2001	jdolecek	Only install headers which are actually used by our userland. This saves about 2.2MB under /usr/include/dev/. Discussed on tech-kern@ recently. I HOPE to get the list right. The headers I left in are ones used for MI tools and those whose usage I discovered by grep over tree sources. Feel free to put needed includes back in if you encounter anything which should not be removed from lists.
1.7	17-Dec-2000	ad	branches: 1.7.2; Add wscons drivers for the DEC PixelStamp graphics accelerators.
1.6	04-Jul-2000	nisimura	Make sure to settle tcdsreg.h and tcdsvar.h in /usr/include/dev/tc/.
1.5	24-Sep-1999	nisimura	branches: 1.5.2; Add 'sfbreg.h' to the list of files installed in /usr/include/dev/tc/.
1.4	13-Apr-1999	ad	Remove px driver pending write of fully-functional MI driver.
1.3	16-Jun-1998	cgd	branches: 1.3.10; Point people to the correct Makefiles to build generated headers. (Suggested by Manuel Bouyer.)
1.2	12-Jun-1998	cgd	Rework the way kernel include files are installed. In the new method, as with user-land programs, include files are installed by each directory in the tree that has includes to install. (This allows more flexibility as to what gets installed, makes 'partial installs' easier, and gives us more options as to which machines' includes get installed at any given time.) The old SYS_INCLUDES={symlinks,copies} behaviours are _both_ still supported, though at least one bug in the 'symlinks' case is fixed by this change. Include files can't be build before installation, so directories that have includes as targets (e.g. dev/pci) have to move those targets into a different Makefile.
1.1	02-Mar-1996	cgd	add ability to define TCVERBOSE, and get "human names" about "known" but unconfigured (or unsupported) devices printed at boot time. The device list is woefully incomplete, because i didn't put much time in it, and because i don't know good "human names" for many TC devices.
1.3.10.1	21-Jun-1999	thorpej	Sync w/ -current.
1.5.2.3	21-Apr-2001	bouyer	Sync with HEAD
1.5.2.2	05-Jan-2001	bouyer	Sync with HEAD
1.5.2.1	20-Nov-2000	bouyer	Update thorpej_scsipi to -current as of a month ago A i386 GENERIC kernel compiles without the siop, ahc and bha drivers (will be updated later). i386 IDE/ATAPI and ncr work, as well as sparc/esp_sbus. alpha should work as well (untested yet). siop, ahc and bha will be updated once I've updated the branch to current -current, as well as machine-dependant code.
1.7.2.3	21-Sep-2001	nathanw	Catch up to -current.
1.7.2.2	24-Aug-2001	nathanw	Catch up with -current.
1.7.2.1	21-Jun-2001	nathanw	Catch up to -current.
1.11.4.1	01-Oct-2001	fvdl	Catch up with -current.
1.11.2.1	10-Jan-2002	thorpej	Sync kqueue branch with -current.
1.2	19-Oct-2008	apb	Use ${TOOL_AWK} instead of ${AWK} or plain "awk" in make commands. Pass AWK=${TOOL_AWK:Q} to shell scripts that use awk.
1.1	12-Jun-1998	cgd	branches: 1.1.146; 1.1.150; 1.1.156; Rework the way kernel include files are installed. In the new method, as with user-land programs, include files are installed by each directory in the tree that has includes to install. (This allows more flexibility as to what gets installed, makes 'partial installs' easier, and gives us more options as to which machines' includes get installed at any given time.) The old SYS_INCLUDES={symlinks,copies} behaviours are _both_ still supported, though at least one bug in the 'symlinks' case is fixed by this change. Include files can't be build before installation, so directories that have includes as targets (e.g. dev/pci) have to move those targets into a different Makefile.
1.1.156.1	13-Dec-2008	haad	Update haad-dm branch to haad-dm-base2.
1.1.150.1	04-May-2009	yamt	sync with head.
1.1.146.1	17-Jan-2009	mjf	Sync with HEAD.
1.63	26-Aug-2001	simonb	Switch to MI SCSI and drop old pmax MD SCSI support completely.
1.62	25-Apr-2001	bouyer	branches: 1.62.2; Pull up the thorpej_scsipi branch to main branch. This is a completely rewritten scsipi_xfer execution engine, and the associated changes to HBA drivers. Overview of changes & features: - All xfers are queued in the mid-layer, rather than doing so in an ad-hoc fashion in individual adapter drivers. - Adapter/channel resource management in the mid-layer, avoids even trying to start running an xfer if the adapter/channel doesn't have the resources. - Better communication between the mid-layer and the adapters. - Asynchronous event notification mechanism from adapter to mid-layer and peripherals. - Better peripheral queue management: freeze/thaw, sorted requeueing during recovery, etc. - Clean separation of peripherals, adapters, and adapter channels (no more scsipi_link). - Kernel thread for each scsipi_channel makes error recovery much easier (no more dealing with interrupt context when recovering from an error). - Mid-layer support for tagged queueing: commands can have the tag type set explicitly, tag IDs are allocated in the mid-layer (thus eliminating the need to use buggy tag ID allocation schemes in many adapter drivers). - support for QUEUE FULL and CHECK CONDITION status in mid-layer; the command will be requeued, or a REQUEST SENSE will be sent as appropriate. Just before the merge syssrc has been tagged with thorpej_scsipi_beforemerge
1.61	02-Nov-2000	mhitch	branches: 1.61.2; When a read DMA transfer is interrupted by a disconnect on the IOASIC SCSI and the buffer is not 8-byte aligned, it leaves a partial transfer in the SDRx registers. This could cause data corruption in dump(8) because the read-ahead buffers are allocated on a non-aligned address. When the read DMA transfer is interrupted and the current DMA position is not aligned, call the dma_end() routine to flush the SDRx register contents to the buffer.
1.60	30-Mar-2000	augustss	branches: 1.60.4; Remove register declarations.
1.59	23-Mar-2000	thorpej	New callout mechanism with two major improvements over the old timeout()/untimeout() API: - Clients supply callout handle storage, thus eliminating problems of resource allocation. - Insertion and removal of callouts is constant time, important as this facility is used quite a lot in the kernel. The old timeout()/untimeout() API has been removed from the kernel.
1.58	14-Mar-2000	nisimura	Unnecessary to enclose device driver body with #if NASC > 0.
1.57	03-Feb-2000	nisimura	Merge IOASIC register definitions.
1.56	15-Nov-1999	nisimura	- No need to include '<machine/autoconf.h>'. - Nuke tc_badaddr() check from asc_tc because the existency check is already done for real TC devices. - Nuke tc_badaddr() check from asc_ioasic because it is a builtin device found in all of IOASIC DECstations.
1.55	18-Jun-1999	mhitch	branches: 1.55.2; 1.55.8; The extraneous interrupt that seems to occur after a reconnect and a DMA transfer starts running can occur on both DMA in and DMA out. I missed the little comment in the Mach driver for the DMA out case. Also, only ignore the interrupt if the TC is non-zero (to match the Mach driver).
1.54	13-Jun-1999	mhitch	Don't pre-load the identify message into the fifo just just before the command register is written. This significantly reduces, if not eliminates, the problem reported in PR#5510. It stops the problem on my 5000/200, and two other people have verified that it fixes the problem on their 5000/200s. I'm waiting for confirmation from the PR originator before closing the PR.
1.53	25-Apr-1999	simonb	Shut 'gcc -Wuninitialized' up.
1.52	12-Apr-1999	pk	Quote "AS IS" as in the majority of Carnegy Mellon notices.
1.51	06-Apr-1999	pk	Fix a pasto in copyright text which has been procreating like rabbits..
1.50	05-Dec-1998	mjacob	branches: 1.50.4; Update HBAs to incorporate the new max_lun property.
1.49	19-Nov-1998	thorpej	Adapt to the new scsipi_adapter interface.
1.48	10-Oct-1998	thorpej	Garbage-collect the open_target_lu and close_target_lu entry points from struct scsipi_adapter; they were not used. Add a scsipi_ioctl entry point to struct scsipi_adapter. This will be used to issue ioctl commands to the host adapters. Inspired by PR #6090, from Matt Jacob.
1.47	13-Aug-1998	eeh	Merge paddr_t changes into the main branch.
1.46	08-May-1998	mhitch	branches: 1.46.2; Fix a problem that will reboot the system with no message as to what the problem was. A collision between a select and reselect would leave TC non-zero from the command-out DMA count, which could later be considered a fatal condition, causing a reboot. The message for that error was only displayed with DEBUG. Fixed by clearing TC on a reselect. The non-zero TC detection won't occur in this case, so unconditionally display the message if it occurs. Workaround for another problem that resulted from an "Illegal Command" status from the 53c94 which would get ignored and result in a timeout (which also reboots the system). Added the missing check for the illegal command status, and add the workaround of resending the "accept message" command to the 53c94. Correct fix will be to determine why the message wasn't sent in the first place. Abort if the resending the command doesn't work. Correctly detect a spurious interrupt and ignore it. This was taken from a newer Mach driver, but did not get the check converted for the design difference between the current NetBSD driver and the Mach driver.
1.45	26-Mar-1998	thorpej	don't use variables declared _inside_ DEBUG in code _outside_ DEBUG
1.44	24-Mar-1998	mhitch	Enable another error message before the driver reboots the machine. It was not being printed if not compiled with DEBUG. Now all situtiations where the driver gives up should display a message before the reboot.
1.43	12-Jan-1998	thorpej	Adjust for changes in config.
1.42	28-Nov-1997	mhitch	Fix driver bug when using an RZ23 (and very likely any other drive that does a "restore data pointers" when reselected after disconnecting in the middle of a DMA transfer). The driver needs a different way to know which script to continue the DMA transfer. The message-in for the "restore data pointers" loses the original "resume" script, and the driver would attempt to continue the DMA transfer at the beginning of the current DMA chunk, rather than at the point the disconnect occured. The result was a spurious console message, and a trashed filesystem.
1.41	27-Aug-1997	bouyer	branches: 1.41.4; Merge scsipi branch in the mainline. This add support for ATAPI devices (currently only CD-ROM drives on i386). The sys/dev/scsipi system provides 2 busses to which devices can attach (scsibus and atapibus). This needed to change some include files and structure names in the low level scsi drivers.
1.40	28-Jul-1997	mhitch	branches: 1.40.2; Use direct DMA with the IOASIC ASC SCSI interface. DMA buffering can be re-enabled with ASC_IOASIC_BOUNCE. All DMA buffered processing is now done in the bus-specific DMA routines in asc_ioasic.c and asc_tc.c. Disable several informational messages dealing with non-empty FIFO conditions, but allow enabling with ASC_DIAGNOSTIC for troubleshooting.
1.39	16-Jun-1997	jonathan	branches: 1.39.2; include <machine/bus.h>.
1.38	07-Jun-1997	mhitch	Fix another weird driver state. After sending the SCSI command to the target after synch negotation during device probes, the 53C94 stops with the target reqesting more command data. The fifo appears to still contain a couple of bytes, so transfer them. If the target still wants command data after that, do a transfer pad. The target seems to function normally after this. A much better solution thant simply rebooting! Also fix a problem when compiling with DIAGNOSTIC - a mismatch between using DIAGNOSTIC and MACH_DIAGNOSTIC caused the compile to fail. Try to start another target and a device disconnects.
1.37	24-May-1997	jonathan	lint: fix %x vs pointer and tyops in error-logging printfs.
1.36	07-Apr-1997	jonathan	Print explanatory message before each panic, or "goto abort" (which panics).
1.35	06-Apr-1997	jonathan	Commit message for previous revision (lost due to Ultrix-compat bug): * Don't print DMA_OUT message in the `normal' case of a 16-byte residual. * ioasic-connected 53c94 devices are always clocked at 25MHz even on machines with 12.5MHz TurboChannel.
1.34	06-Apr-1997	jonathan	* empty log message *
1.33	29-Mar-1997	mhitch	A couple of missed boot() -> cpu_reboot() changes.
1.32	10-Dec-1996	thorpej	Fill in sc_link.max_target
1.31	13-Oct-1996	christos	backout kprintf changes
1.30	10-Oct-1996	christos	printf -> kprintf, sprintf -> ksprintf
1.29	29-Sep-1996	jonathan	Fix data-corruption bug on async targets: * When we are transferring in DATA (in asc_dma_in) and the target is an async device, there is sometimes an extra byte in the FIFO. If so, we need to drain that byte out of the fifo, but if and only if the target is async. See also the comments in asc_dma_in() in the related Mach mk84 asc driver (scsi_53C94_hdw.c), which has an identical fix but applied in more restrictive conditions than we need, with async disk targets, as well as async tapes. * Add a watchdog and timeout active SCSI requests, to eliminate any potential for deadlock due to applying the fix above on newer silicon versions of the 53c94 which may not have the above problem. Should use the MI scsi per-target timeout instead, when available.
1.28	25-Sep-1996	jonathan	* Rewrite asc driver with ``mi'' backend and parent-specific front-end cfattach code for TC SCSI option cards and ioasic 53c94 baseboard SCSI. ascvar.h: shared softc declarations asc_ioasic.c: ioasic front-end code. asc_tc.c: Turbochannel option (and 5000/200 basebard) front-end code. * ioasic_attach meeds more work to eliminate pmax_type dependency and to verify the clocks speed passed to 53c94. * Add prototypes for asc script entry points; should compile with -Wstrict-prototypes -Wmissing-prototypes. * Use tcvar.h interface. The usage of tc_syncbus() and tc_mb() may not be quite stylistically on an Alhpa, but it apparently makes no difference on the eerly-generation Alpha CPUs in TC Alphas.
1.27	28-Aug-1996	cgd	(1) set scsi_link channel to either the appropriate channel (if a multi-channel driver), or to SCSI_CHANNEL_ONLY_ONE if a single-channel driver. (2) use scsiprint() rather than a locally-defined autoconfig print function, and kill any locally-defined print function.
1.26	27-Aug-1996	cgd	change cfprint_t type definition to take a const char , rather than a char , because that's what was really intended, and because if the print function modifies the string, various things could become unhappy (so the string should _not_ be modified).
1.25	09-Aug-1996	mrg	Change reboot(2) to take two arguments: bootopt like normal and also a boot string for firmware that can do this, such as the SPARC and the sun3 models. It is currently silently ignored on all other hardware now, however. The MD function "boot()" has been changed to also take a char *.
1.24	30-Jul-1996	mhitch	Remove the "goto abort" (which currently reboots the machine) when the FIFO is non-empty when the message-in phase occurs before the DMA output starts. This showed up on a Micropolis drive.
1.23	16-Jul-1996	mhitch	Don't flush the 53C94 fifo when starting dma_in. The fifo data is valid at that point, and flushing the fifo will hang the system.
1.22	11-Jun-1996	mhitch	Try to avoid collisions with reselection when starting a new selection. Enable reselections as soon as possible after a disconnect - prevents losing a reselecting device. Check for and ignore a spurious interrupt during a DMA input (from the Mach driver).
1.21	04-Jun-1996	mhitch	Fix the oversight that the ASC SCSI adapter can also be on the Turbochannel as well as the IOASIC. It should now work on the 5000/200. Removed the "aborts" which could leave the disk trashed when the abort rebooted the system. Fix the data corruption problem by clearing the FIFO before starting a data transfer.
1.20	29-May-1996	mhitch	Fix the DECstation ASC SCSI driver autoconfiguration to more closely match the alpha. The DS3100 will now configure properly. Also fix the name in the cfdriver structure - somewhere it got changed from "asc" to "as".
1.19	20-May-1996	jonathan	branches: 1.19.2; * Fix formatstr/argument mismatches in diagnostic printf()s. * Change MachEmptyWriteBuffer() to wbflush(). Should use TC mi names tc_mb(), tc_wmb, tc_syncbus() but I'm not sure which each wbflush() should be. * Add prototyped forward decl for asc_Dumplog() and add an explicit void return type. * Remove unused variables.
1.18	18-Mar-1996	jonathan	Additional fixes to complete the NetBSD/1.1B config changes: Add new device-attach struct cfattach asc_ca and struct cfdriver asc_cd. Change cfdriver references from "XXXcd" to "XXX_cd".
1.17	02-Feb-1996	jonathan	Resolve pmax and alpha IOCTL asic driver differences, pass 1: Rename the ioctl asic register and slot macros from ASIC_<xxx> to IOASIC_<xxx>, to be compatible with the machine-indpendent names in sys/dev/tc/ioasicvar.h. The pmax code still uses sys/arch/pmax/pmax/asic.h, as some of the registers and offsets defined there are not yet defined in sys/dev/tc/ioasicvar.h. Rename the ioctl asic base-address pointer from `asic_base' to `ioasic_base'. Use the device address in the attach_args structure, instead of using the deprecated BUS_CVTADDR macro. Change the Mach derived asc driver to use "SCSI_PHASE_xxx" instead of "ASC_PHASE_xxx", as the latest version of the Mach driver does.
1.16	04-Jan-1996	jonathan	Commit trivial changes from Mach MK84 to force sup'ables source to be updated: Drop spurious interrupts in asc_intr(). Read back the pending SCSI command so asc_intr() can add it to the asc SCSI log.
1.15	13-Sep-1995	jonathan	Rename the old pmax SCSI driver's "struct scsi_device" to "struct pmax_scsi_device", to avoid name conflicts with the sys/dev/scsi SCSI driver.
1.14	11-Sep-1995	jonathan	Rename the old 4.4bsd/pmax old-style config "struct device" to "struct pmax_device" to avoid conflict with <sys/device.h>. Change the signature of interrupt-handlers to take a void * (a pointer to the softc) and return an int (indicating spurious interrupts or other conditions.)
1.13	21-Aug-1995	jonathan	Change pmax ASC driver to use dynamically-allocated softc structures. Concomitant changes to code that prints driver/unit name: use dv_xname and dv_unit, instead of doing pointer arithmetic on elements of the static softc array. Remove support for old config. The old-config "driver" structure is still present, because the pmax non-MI SCSI driver needs it. Merge some off Per Fogelstrom's changes for the Pica driver, which uses the machine-independent SCSI code. This is #ifdef'ed out until the DMA is fixed to work on Decstations, too.
1.12	10-Aug-1995	jonathan	Update DECstation drivers to use new-style config, removing old-style config support, except for SCSI disks and tapes.
1.11	04-Aug-1995	jonathan	Add preliminary support for new-style configuration: struct cfdriver, and match and attach code. Still use the static softc so that drivers work with kernels configured with either new or old config.
1.10	05-Dec-1994	dean	fix problem with disconnects (Ralph Campbell)
1.9	01-Dec-1994	dean	added missing #ifdef DEBUG

1.50.4.1	07-Apr-1999	pk	Pull up from trunk: copyright text warts.
1.50.4.2.4.1	30-Nov-1999	itojun	bring in latest KAME (as of 19991130, KAME/NetBSD141) into kame branch just for reference purposes. This commit includes 1.4 -> 1.4.1 sync for kame branch. The branch does not compile at all (due to the lack of ALTQ and some other source code). Please do not try to modify the branch, this is just for referenre purposes. synchronization to latest KAME will take place on HEAD branch soon.

1.55.2.3	29-Mar-2001	bouyer	Port to thorpej_scsipi. This didn't compile with MI scsi anyway, but I prefer to remove all references to sc_link/scsipi_link.
1.55.2.2	22-Nov-2000	bouyer	Sync with HEAD.
1.55.2.1	20-Nov-2000	bouyer	Update thorpej_scsipi to -current as of a month ago A i386 GENERIC kernel compiles without the siop, ahc and bha drivers (will be updated later). i386 IDE/ATAPI and ncr work, as well as sparc/esp_sbus. alpha should work as well (untested yet). siop, ahc and bha will be updated once I've updated the branch to current -current, as well as machine-dependant code.
1.60.4.1	02-Nov-2000	tv	Pullup 1.61 [mhitch]: When a read DMA transfer is interrupted by a disconnect on the IOASIC SCSI and the buffer is not 8-byte aligned, it leaves a partial transfer in the SDRx registers. This could cause data corruption in dump(8) because the read-ahead buffers are allocated on a non-aligned address. When the read DMA transfer is interrupted and the current DMA position is not aligned, call the dma_end() routine to flush the SDRx register contents to the buffer.
1.61.2.2	28-Feb-2002	nathanw	Catch up to -current.
1.61.2.1	21-Jun-2001	nathanw	Catch up to -current.
1.62.2.1	13-Sep-2001	thorpej	Update the kqueue branch to HEAD.
1.24	26-Aug-2001	simonb	Switch to MI SCSI and drop old pmax MD SCSI support completely.
1.23	05-Nov-2000	mhitch	branches: 1.23.2; 1.23.4; When doing the cacheflush for MIPS1, adjust the length to account for an unaligned buffer. The last word of the buffer was not getting flushed if the buffer was unaligned and fit in a single DMA segment. Now dump(8) works on both MIPS1 and MIPS3 DECstations.
1.22	28-Sep-2000	mhitch	Set up the physical addresses for DMAPTR/NEXTPTR before adjusting for unaligned transfers and adjust the physical address to align the transfer. If the buffer end just crossed the page boundary, the computation of the NEXTPTR physical address resulted in using -1. The cleanup at the end of the DMA transfer would try to copy the residual data to physical address 0x1ffffffc. This would silently corrupt data on the R3000 and usually would hang the R4000.
1.21	06-Mar-2000	mhitch	branches: 1.21.4; Get rid of hook for dk_establish() - pmax will now use device_register().
1.20	04-Mar-2000	mhitch	Fix boot device detection. Device probes are not done when adapters are configured, but after all adapters have been configured. When multiple adapters are present, only the last configured adapter could be matched to the boot device slot. The adapter attach routines now check if that adapter slot matches the boot device slot and saves the softc pointer for that controller. Then when the disks are configured, dk_establish() matches the appropriate controller.
1.19	03-Feb-2000	nisimura	Use bus_space_{write,read} for IOASIC register access.
1.18	03-Dec-1999	mhitch	Fix IOASIC DMA alignment problems. Buffers not aligned on doubleword (8 byte) boundaries don't work correctly. Make use of the SDR0/SDR1 registers to adjust the buffer alignment when starting the DMA transfer. Block device I/O done by the filesystems will usually be aligned correctly, but character device I/O may not be aligned correctly. This should fix the problems with dump(8) failing randomly on DECstations.
1.17	15-Nov-1999	nisimura	- No need to include '<machine/autoconf.h>'. - Nuke tc_badaddr() check from asc_tc because the existency check is already done for real TC devices. - Nuke tc_badaddr() check from asc_ioasic because it is a builtin device found in all of IOASIC DECstations.

All DMA buffered processing is now done in the bus-specific DMA routines in asc_ioasic.c and asc_tc.c. Disable several informational messages dealing with non-empty FIFO conditions, but allow enabling with ASC_DIAGNOSTIC for troubleshooting.

The usage of tc_syncbus() and tc_mb() may not be quite stylistically on an Alhpa, but it apparently makes no difference on the eerly-generation Alpha CPUs in TC Alphas.

1.21.4.2	05-Nov-2000	tv	Pullup 1.23 [mhitch]: When doing the cacheflush for MIPS1, adjust the length to account for an unaligned buffer. The last word of the buffer was not getting flushed if the buffer was unaligned and fit in a single DMA segment. Now dump(8) works on both MIPS1 and MIPS3 DECstations.
1.21.4.1	30-Sep-2000	mhitch	Pull up rev 1.22 [approved by thorpej. Set up the physical addresses for DMAPTR/NEXTPTR before adjusting for unaligned transfers and adjust the physical address to align the transfer. If the buffer end just crossed the page boundary, the computation of the NEXTPTR physical address resulted in using -1. The cleanup at the end of the DMA transfer would try to copy the residual data to physical address 0x1ffffffc. This would silently corrupt data on the R3000 and usually would hang the R4000.

1.26	03-Sep-2018	riastradh	Rename min/max -> uimin/uimax for better honesty. These functions are defined on unsigned int. The generic name min/max should not silently truncate to 32 bits on 64-bit systems. This is purely a name change -- no functional change intended. HOWEVER! Some subsystems have #define min(a, b) ((a) < (b) ? (a) : (b)) #define max(a, b) ((a) > (b) ? (a) : (b)) even though our standard name for that is MIN/MAX. Although these may invite multiple evaluation bugs, these do _not_ cause integer truncation. To avoid `fixing' these cases, I first changed the name in libkern, and then compile-tested every file where min/max occurred in order to confirm that it failed -- and thus confirm that nothing shadowed min/max -- before changing it. I have left a handful of bootloaders that are too annoying to compile-test, and some dead code: cobalt ews4800mips hp300 hppa ia64 luna68k vax acorn32/if_ie.c (not included in any kernels) macppc/if_gm.c (superseded by gem(4)) It should be easy to fix the fallout once identified -- this way of doing things fails safe, and the goal here, after all, is to _avoid_ silent integer truncations, not introduce them. Maybe one day we can reintroduce min/max as type-generic things that never silently truncate. But we should avoid doing that for a while, so that existing code has a chance to be detected by the compiler for conversion to uimin/uimax without changing the semantics until we can properly audit it all. (Who knows, maybe in some cases integer truncation is actually intended!)

Overview of changes & features: - All xfers are queued in the mid-layer, rather than doing so in an ad-hoc fashion in individual adapter drivers. - Adapter/channel resource management in the mid-layer, avoids even trying to start running an xfer if the adapter/channel doesn't have the resources. - Better communication between the mid-layer and the adapters. - Asynchronous event notification mechanism from adapter to mid-layer and peripherals. - Better peripheral queue management: freeze/thaw, sorted requeueing during recovery, etc. - Clean separation of peripherals, adapters, and adapter channels (no more scsipi_link). - Kernel thread for each scsipi_channel makes error recovery much easier (no more dealing with interrupt context when recovering from an error). - Mid-layer support for tagged queueing: commands can have the tag type set explicitly, tag IDs are allocated in the mid-layer (thus eliminating the need to use buggy tag ID allocation schemes in many adapter drivers). - support for QUEUE FULL and CHECK CONDITION status in mid-layer; the command will be requeued, or a REQUEST SENSE will be sent as appropriate.

1.5	19-Nov-1998	thorpej	branches: 1.5.10; Adapt to the new scsipi_adapter interface.
1.4	28-Nov-1997	mhitch	Fix driver bug when using an RZ23 (and very likely any other drive that does a "restore data pointers" when reselected after disconnecting in the middle of a DMA transfer). The driver needs a different way to know which script to continue the DMA transfer. The message-in for the "restore data pointers" loses the original "resume" script, and the driver would attempt to continue the DMA transfer at the beginning of the current DMA chunk, rather than at the point the disconnect occured. The result was a spurious console message, and a trashed filesystem.
1.3	27-Aug-1997	bouyer	branches: 1.3.4; Merge scsipi branch in the mainline. This add support for ATAPI devices (currently only CD-ROM drives on i386). The sys/dev/scsipi system provides 2 busses to which devices can attach (scsibus and atapibus). This needed to change some include files and structure names in the low level scsi drivers.
1.2	28-Jul-1997	mhitch	branches: 1.2.2; Use direct DMA with the IOASIC ASC SCSI interface. DMA buffering can be re-enabled with ASC_IOASIC_BOUNCE. All DMA buffered processing is now done in the bus-specific DMA routines in asc_ioasic.c and asc_tc.c. Disable several informational messages dealing with non-empty FIFO conditions, but allow enabling with ASC_DIAGNOSTIC for troubleshooting.
1.1	25-Sep-1996	jonathan	branches: 1.1.8; * Rewrite asc driver with ``mi'' backend and parent-specific front-end cfattach code for TC SCSI option cards and ioasic 53c94 baseboard SCSI. ascvar.h: shared softc declarations asc_ioasic.c: ioasic front-end code. asc_tc.c: Turbochannel option (and 5000/200 basebard) front-end code. * ioasic_attach meeds more work to eliminate pmax_type dependency and to verify the clocks speed passed to 53c94. * Add prototypes for asc script entry points; should compile with -Wstrict-prototypes -Wmissing-prototypes. * Use tcvar.h interface. The usage of tc_syncbus() and tc_mb() may not be quite stylistically on an Alhpa, but it apparently makes no difference on the eerly-generation Alpha CPUs in TC Alphas.

1.46	12-Sep-2020	isaki	Improve am7930 family drivers to share more code. audioamd(4) on sparc, vsaudio(4) on vax, and bba(4) are. - Remove complex and useless callbacks: onopen, onclose, and indirect_{read,write}. This makes audioamd and vsaudio almost the same. - Remove (already disabled) assembly fast interrupt path from audioamd(4). cf. http://mail-index.netbsd.org/source-changes/2009/12/19/msg004585.html - Use trigger_* method rather than start_* method. It's more suitable. vsaudio(4) was tested by naru@, bba(4) was tested by tsutsui@.
1.45	29-Aug-2020	isaki	Fix white space and indent.
1.44	08-Jun-2019	isaki	Clean get_props(). - Make get_props() return AUDIO_PROP_{PLAYBACK,CAPTURE} properly. This eliminates need for audio.c to take care of such (old) drivers which don't return both of PLAYBACK and CAPTURE. - All get_props() doesn't need to return AUDIO_PROP_MMAP. It is handled in the audio layer now.
1.43	08-May-2019	isaki	Merge isaki-audio2 branch, the overhaul of audio subsystem. - Interrupt-oriented system rather than thread-oriented. - Improve stability, quality and performance. - Split playback and record cleanly. Improve halfduplex support. - Many bugs are fixed including deadlocks, resource leaks, abuses, etc. - Simplify audio filter mechanism. The encoding/channels/frequency conversions are completely handled in the upper layer. So the hard- ware driver only converts its hardware encoding (if necessary). - audio_hw_if changes: - Obsoletes query_encoding and add query_format instead. - Obsoletes set_params and add set_format instead. - Remove drain, setfd, mappage. - The call sequences are changed. - ioctl AUDIO_GETFD/SETFD, AUDIO_GETCHAN/SETCHAN are obsoleted. - ioctl AUDIO_{QUERY,GET,SET}FORMAT are introduced. - cleanup config attributes: au*conv and mulaw. - All hardware drivers should follow it (I've done as much as possible). Some file paths are changed: - dev/audio.c -> dev/audio/audio.c (rewritten) - dev/audiovar.h -> dev/audio/audiovar.h - dev/audio_dai.h -> dev/audio/audio_dai.h - dev/audio_if.h -> dev/audio/audio_if.h - dev/audiobell.c -> dev/audio/audiobell.c - dev/audiobellvar.h -> dev/audio/audiobellvar.h - dev/mulaw.[ch] -> dev/audio/mulaw.[ch] + dev/audio/alaw.c
1.42	16-Mar-2019	isaki	branches: 1.42.2; Use C99 style struct initializer to audio_hw_if.
1.41	03-Sep-2018	riastradh	Rename min/max -> uimin/uimax for better honesty. These functions are defined on unsigned int. The generic name min/max should not silently truncate to 32 bits on 64-bit systems. This is purely a name change -- no functional change intended. HOWEVER! Some subsystems have #define min(a, b) ((a) < (b) ? (a) : (b)) #define max(a, b) ((a) > (b) ? (a) : (b)) even though our standard name for that is MIN/MAX. Although these may invite multiple evaluation bugs, these do _not_ cause integer truncation. To avoid `fixing' these cases, I first changed the name in libkern, and then compile-tested every file where min/max occurred in order to confirm that it failed -- and thus confirm that nothing shadowed min/max -- before changing it. I have left a handful of bootloaders that are too annoying to compile-test, and some dead code: cobalt ews4800mips hp300 hppa ia64 luna68k vax acorn32/if_ie.c (not included in any kernels) macppc/if_gm.c (superseded by gem(4)) It should be easy to fix the fallout once identified -- this way of doing things fails safe, and the goal here, after all, is to _avoid_ silent integer truncations, not introduce them. Maybe one day we can reintroduce min/max as type-generic things that never silently truncate. But we should avoid doing that for a while, so that existing code has a chance to be detected by the compiler for conversion to uimin/uimax without changing the semantics until we can properly audit it all. (Who knows, maybe in some cases integer truncation is actually intended!)
1.40	01-Jun-2017	chs	branches: 1.40.8; 1.40.10; remove checks for failure after memory allocation calls that cannot fail: kmem_alloc() with KM_SLEEP kmem_zalloc() with KM_SLEEP percpu_alloc() pserialize_create() psref_class_create() all of these paths include an assertion that the allocation has not failed, so callers should not assert that again.
1.39	23-Nov-2011	jmcneill	branches: 1.39.8; 1.39.26; Merge jmcneill-audiomp3 branch, which is derived from ad-audiomp2. From the original ad-audiomp branch notes: Add MP locking to the audio drivers. Making the audio drivers MP safe is necessary before efforts can be made to make the VM system MP safe. The are two locks per device instance, an ISR lock and a character device lock. The ISR lock replaces calls to splaudio()/splx(), and will be held across calls to device methods which were called at splaudio() before (e.g. trigger_output). The character device lock is held across calls to nearly all of the methods, excluding some only used for initialization, e.g. get_locks. Welcome to 5.99.57.

1.23	10-Jan-2005	kent	merge kent-audio1 branch, which introduces audio filter pipeline to the MI audio framework Summary of changes: * struct audio_params - remove sw_code, factor, factor_denom, hw_sample_rate, hw_encoding ,hw_precision, and hw_channels. Conversion information is conveyed by stream_filter_list_t. - change the type of sample_rate: u_long -> u_int - add `validbits,' which represents the valid data size in precision bits. It is required in order to distinguish 24/32bit from 24/24bit or 32/32bit. * audio_hw_if - add two parameters to set_params() stream_filter_list_t pfil, stream_filter_list rfil A HW driver should set filter recipes for requested formats - constify audio_params parameters of trigger_output() and trigger_input(). They represent audio formats for the hardware. - make open() and close() optional - add int (AUMODE_PLAY or AUMODE_RECORD) and audio_params_t parameters to round_blocksize() * sw_code is replaced with stream_filter_t. stream_filer_t converts audio data in an input buffer and writes into another output buffer unlike sw_code, which converts data in single buffer. converters in dev/auconv.c, dev/mulaw.c, dev/aurateconv.c, dev/tc/bba.c, dev/ic/msm6258.c, and arch/arm/iomd/vidcaudio.c are reimplemented as stream_filter_t * MI audio - audiosetinfo() builds filter pipelines from stream_filter_list_t filled by audio_hw_if::set_params() - audiosetinfo() returns with EINVAL if mmapped and set_params() requests filters - audio_write(), audio_pint(), and audio_rint() invoke a filter pipeline. - ioctl() for FIONREAD, AUDIO_WSEEK, AUDIO_GETIOFFS, AUDIO_GETOOFFS, and audio_prinfo::{seek,samples} for AUDIO_GETINFO handle values for a buffer nearest to userland. * add `struct device ' parameter to ac97_attach() all of audio HW drivers follow audio_hw_if and ac97 changes

1.11	18-Jul-2000	thorpej	Back out previous. It is no longer needed, as both the Alpha and DECstation IOASIC drivers clear the appropriate interrupts in the dispatch routine.
1.10	17-Jul-2000	thorpej	Clear the DMA pointer reload interrupt bits in the IOASIC_INTR register to prevent interrups from looping on the Alpha. From Izumi Tsutsui <tsutsui@ceres.dti.ne.jp>.
1.9	17-Jul-2000	thorpej	- Write the registers 7930 registers properly on the Alpha (it's different than on the DECstation). - Use IOASIC_DMA_BLOCKSIZE instead of PAGE_SIZE. Should make this work on the Alpha. From discussion with Izumi Tsutsui, Gregory McGarry, and Chris Demetriou, and much reading of EK-D3SYS-PM.

1.7	26-Jun-2000	simonb	Change the kernel mmap interface so that the offset to map is an "off_t" and the return value is a "paddr_t" to allow mappings at offsets past 2^31 bytes. Somewhat inspired by FreeBSD, which only changed the offset to a "vm_offset_t". Includes updates for the i386, pc532 and sh3 mmmmap from Jason Thorpe.

Filter pipelines for user encoding are not necessary in audio2 so the driver only needs to handle its hardware encoding. - audioamd/vsaudio use an ordinal linear-mulaw conversion filter and bba requires special one. dev/audio/mulaw.c supports this variant just for bba. It might not a good way for bba but it keeps all other drivers simple. - Tested on vsaudio(4) by naru@, bba(4) by tsutsui@ (a few months ago). Thanks!
1.66	06-Dec-2021	abs	Add WSDISPLAYIO_GET_FBINFO support to most TURBOchannel framebuffers This adds WSDISPLAYIO_GET_FBINFO to cfb, mfb, sfb, tfb and xcfb TURBOchannel framebuffers as used by pmax and alpha It does not add support to px and pxg (they handle ioctls in common code in stic.c and more careful wiring is required) These changes allow an Xswfb X server to use the framebuffer directly, albeit without any special acceleration A subsequent change will re-enable X server building on pmax, and also hopefully switch alpha from Xorg 1.10 to 1.20
1.65	07-Aug-2021	thorpej	Merge thorpej-cfargs2.
1.64	24-Apr-2021	thorpej	branches: 1.64.8; Merge thorpej-cfargs branch: Simplify and make extensible the config_search() / config_found() / config_attach() interfaces: rather than having different variants for which arguments you want pass along, just have a single call that takes a variadic list of tag-value arguments. Adjust all call sites: - Simplify wherever possible; don't pass along arguments that aren't actually needed. - Don't be explicit about what interface attribute is attaching if the device only has one. (More simplification.) - Add a config_probe() function to be used in indirect configuiration situations, making is visibly easier to see when indirect config is in play, and allowing for future change in semantics. (As of now, this is just a wrapper around config_match(), but that is an implementation detail.) Remove unnecessary or redundant interface attributes where they're not needed. There are currently 5 "cfargs" defined: - CFARG_SUBMATCH (submatch function for direct config) - CFARG_SEARCH (search function for indirect config) - CFARG_IATTR (interface attribte) - CFARG_LOCATORS (locators array) - CFARG_DEVHANDLE (devhandle_t - wraps OFW, ACPI, etc. handles) ...and a sentinel value CFARG_EOL. Add some extra sanity checking to ensure that interface attributes aren't ambiguous. Use CFARG_DEVHANDLE in MI FDT, OFW, and ACPI code, and macppc and shark ports to associate those device handles with device_t instance. This will trickle trough to more places over time (need back-end for pre-OFW Sun OBP; any others?).
1.63	10-Nov-2019	chs	branches: 1.63.10; in many device attach paths, allocate memory with M_WAITOK instead of M_NOWAIT and remove code to handle failures that can no longer happen.

1.51	04-Mar-2007	christos	Kill caddr_t; there will be some MI fallout, but it will be fixed shortly.
1.50	12-Apr-2006	jmmv	branches: 1.50.14; Add an extra cookie to the ioctl and mmap wsdisplay accessops that points to the screen on which they are being called. The driver cannot guess this by itself but it is needed to implement, at least, the getwschar and putwschar functions in the correct place. There are no functional changes yet. Tested on i386 (vga, vga_raster, machfb, vesafb), macppc and sparc64. Suggested and reviewed by macallan@.
1.49	31-Mar-2006	thorpej	Use ANSI function decls, apply static.
1.48	30-Mar-2006	thorpej	Use device_private().

1.44	20-Dec-2003	nisimura	- Minor coding modifications for VDAC register access. - De-__P() this time. Tested valid with 4MAXINE.
1.43	17-Dec-2003	ad	- Restore the display to a sane state when leaving mapped mode. - OR updates into sc_changed, and protect with spltty()/splx().
1.42	13-Nov-2003	chs	eliminate uvm_useracc() in favor of checking the return value of copyin() or copyout(). uvm_useracc() tells us whether the mapping permissions allow access to the desired part of an address space, and many callers assume that this is the same as knowing whether an attempt to access that part of the address space will succeed. however, access to user space can fail for reasons other than insufficient permission, most notably that paging in any non-resident data can fail due to i/o errors. most of the callers of uvm_useracc() make the above incorrect assumption. the rest are all misguided optimizations, which optimize for the case where an operation will fail. we'd rather optimize for operations succeeding, in which case we should just attempt the access and handle failures due to insufficient permissions the same way we handle i/o errors. since there appear to be no good uses of uvm_useracc(), we'll just remove it.
1.41	27-Oct-2003	chs	uninitialized variables
1.40	29-Jun-2003	fvdl	branches: 1.40.2; Back out the lwp/ktrace changes. They contained a lot of colateral damage, and need to be examined and discussed more.

1.36	19-Aug-2002	itohy	Leaving overflow-sensitive code, very similar to what was fixed in the previous changes to cfb.c / sfb.c / xcfb.c, would not be clever. Just modify in the similar way.
1.35	19-Aug-2002	itohy	Make it compile again. Hi, itojun!
1.34	06-Aug-2002	itojun	integer overflow. from silvio@qualys.com
1.33	04-Jul-2002	junyoung	alloc_attr -> allocattr Approved by Matthias Drochner.
1.32	17-Mar-2002	atatat	branches: 1.32.4; 1.32.6; Convert ioctl code to use EPASSTHROUGH instead of -1 or ENOTTY for indicating an unhandled "command". ERESTART is -1, which can lead to confusion. ERESTART has been moved to -3 and EPASSTHROUGH has been placed at -4. No ioctl code should now return -1 anywhere. The ioctl() system call is now properly restartable.
1.31	13-Mar-2002	ad	Reorganise the wsfont stuff slightly so that multiple display adapters with different bit/byte order requirements can co-exist happily.

1.27	20-Apr-2001	reinoud	branches: 1.27.2; Fix a few race conditions ... the VSYNC update flag could be cleared resulting in a blank screen when f.e. a setcursor ioctl was called after the screenblanker had enabled the screen again ... the actual switching on was then never performed at VSYNC. A simple \|= instead of = does the trick ... just leave the other bits on please :)
1.26	16-Jan-2001	nisimura	branches: 1.26.2; - relocate the code to place sprite cursor inside interrupt handlers called on every virtical replace. - efforts to make the code strucutures similar across TC framebuffers.
1.25	21-Nov-2000	nisimura	Fix errors in color lookup table initialization. Glyph is rendered in visible color now.
1.24	27-Oct-2000	nisimura	Fix errors in initializing the software copy of 256 entry colormap stored in device softc. rasops_cmap[] array is orginazed in 256 iteration of 3 byte long RBG triplet, which does not match with struct wsdisplay_cmap design.
1.23	13-Sep-2000	nisimura	Found glyph pixel order inverted on screen.
1.22	28-Jun-2000	mrg	remove include of <vm/vm.h>. <vm/vm.h> -> <uvm/uvm_extern.h>
1.21	26-Jun-2000	simonb	Change the kernel mmap interface so that the offset to map is an "off_t" and the return value is a "paddr_t" to allow mappings at offsets past 2^31 bytes. Somewhat inspired by FreeBSD, which only changed the offset to a "vm_offset_t". Includes updates for the i386, pc532 and sh3 mmmmap from Jason Thorpe.
1.20	16-Mar-2000	nisimura	branches: 1.20.4; Place 34 by 80 console at the center of screen.
1.19	14-Mar-2000	nisimura	Respect video console colour designation by configration file.
1.18	14-Mar-2000	nisimura	Switch to improved flexible video console text rasterizer provided by rasops and wsfont.
1.17	15-Dec-1999	ad	- Change prefix for Bt459 register defs to BT459_IREG to indicate that these are indirectly accessed registers. - Add defs for directly accessed registers to bt459reg.h.
1.16	08-Dec-1999	nisimura	One small mod. escaped from the last commit.

1.12	02-Aug-1999	nisimura	branches: 1.12.2; 1.12.4; - Fix TX 8bpp framebuffer size, which occupies 2MB. - Rework CX RAMDAC register access like as other TC framebuffers.
1.11	07-May-1999	nisimura	- Sweep abit preparing for code merge to have common 'vdacops' across various graphics cards.
1.10	29-Mar-1999	nisimura	branches: 1.10.4; - Unnecessary to have '#include <machine/autoconf.h>' for those.
1.9	24-Mar-1999	mrg	completely remove Mach VM support. all that is left is the all the header files as UVM still uses (most of) these.
1.8	01-Mar-1999	nisimura	- Fix cursor image validity check error in set_cursor().
1.7	15-Jan-1999	thorpej	__pmax__ -> pmax, like other ports.
1.6	11-Jan-1999	drochner	remove dummy "load_font" entries
1.5	19-Nov-1998	mrg	fix problems in many d_mmap routines: - returned EOPNOTSUPP rather than -1. - no check for negative offset. many of these fix potential security problems in these drivers. XXX XXX XXX the d_mmap cdev routine should be changed to have a prototype like: paddr_t (*d_mmap) __P((dev_t, off_t, int)); by someone!
1.4	18-Nov-1998	nisimura	- Fix cursor image handling bugs escaped in last commit.
1.3	09-Nov-1998	nisimura	- Fix many errors in cursor image manipulation. Hardware expect 2 bit/pixel format, not planer format. Assign MSB for cursor mask and LSB for cursor image, where 10 means mask color and 11 for image color. Image bit order of Bt431 and Bt459 are opposite to MIPS/Alpha processors while IMS G332 and DC503 (PCC) are indentical. - Assume that cursor images are 32 pixel padded as ULTRIX/DU ws interface do. It's natural to X server. - XXX Vast majority of codes are duplicated between mfb<->tfb and cfb<->sfb. Code sharing might be achieved in the context of TGA/SFB+ merge.
1.2	30-Oct-1998	nisimura	- Assign copyright terms.
1.1	29-Oct-1998	nisimura	- Introduce MI NWSCONS drivers for TURBOchannel framebuffer option cards. N.B., Digital UNIX never supports neither PMAG-AA (mfb) nor PMAG-BA (cfb) for TC Alphas. PMAG-DV (xcfb) is Personal DECstation built in. All should be good for console, but need much works for cursor/colormap completeness.

1.2	17-Apr-1996	cgd	branches: 1.2.2; clean up clock handling: clock drivers are now seperate from the chip-independent clock code. 'clock' has been renamed 'mcclock' 'clock' has been renamed 'mcclock' (since it's a driver for that particular clock, and since eventually there may be another clock chip driver), and now attaches via seperate match/attach functions to both TC and ISA. This removes a whole lot of #ifdefs...

1.36	20-Jan-2020	thorpej	Remove FDDI support.
1.35	08-May-2019	isaki	branches: 1.35.4; Merge isaki-audio2 branch, the overhaul of audio subsystem. - Interrupt-oriented system rather than thread-oriented. - Improve stability, quality and performance. - Split playback and record cleanly. Improve halfduplex support. - Many bugs are fixed including deadlocks, resource leaks, abuses, etc. - Simplify audio filter mechanism. The encoding/channels/frequency conversions are completely handled in the upper layer. So the hard- ware driver only converts its hardware encoding (if necessary). - audio_hw_if changes: - Obsoletes query_encoding and add query_format instead. - Obsoletes set_params and add set_format instead. - Remove drain, setfd, mappage. - The call sequences are changed. - ioctl AUDIO_GETFD/SETFD, AUDIO_GETCHAN/SETCHAN are obsoleted. - ioctl AUDIO_{QUERY,GET,SET}FORMAT are introduced. - cleanup config attributes: au*conv and mulaw. - All hardware drivers should follow it (I've done as much as possible). Some file paths are changed: - dev/audio.c -> dev/audio/audio.c (rewritten) - dev/audiovar.h -> dev/audio/audiovar.h - dev/audio_dai.h -> dev/audio/audio_dai.h - dev/audio_if.h -> dev/audio/audio_if.h - dev/audiobell.c -> dev/audio/audiobell.c - dev/audiobellvar.h -> dev/audio/audiobellvar.h - dev/mulaw.[ch] -> dev/audio/mulaw.[ch] + dev/audio/alaw.c
1.34	11-Aug-2016	christos	branches: 1.34.16; 1.34.20; TURBOchannel usb/gpio driver from Felix Deichmann

1.32	13-Nov-2007	cube	branches: 1.32.10; 1.32.14; Remove some whitespace.
1.31	17-Aug-2006	bjh21	branches: 1.31.26; 1.31.28; 1.31.32; 1.31.34; There seems to be no good reason for sfbp(4) to be commented out here, and its state is breaking alpha builds. I'll uncomment it and see what breaks.
1.30	29-Jul-2006	ad	branches: 1.30.2; Remove RASTERCONSOLE support from the pmax port.
1.29	11-Dec-2005	christos	branches: 1.29.4; 1.29.8; merge ktrace-lwp.
1.28	10-Jan-2005	kent	branches: 1.28.10; merge kent-audio1 branch, which introduces audio filter pipeline to the MI audio framework Summary of changes: * struct audio_params - remove sw_code, factor, factor_denom, hw_sample_rate, hw_encoding ,hw_precision, and hw_channels. Conversion information is conveyed by stream_filter_list_t. - change the type of sample_rate: u_long -> u_int - add `validbits,' which represents the valid data size in precision bits. It is required in order to distinguish 24/32bit from 24/24bit or 32/32bit. * audio_hw_if - add two parameters to set_params() stream_filter_list_t pfil, stream_filter_list rfil A HW driver should set filter recipes for requested formats - constify audio_params parameters of trigger_output() and trigger_input(). They represent audio formats for the hardware. - make open() and close() optional - add int (AUMODE_PLAY or AUMODE_RECORD) and audio_params_t parameters to round_blocksize() * sw_code is replaced with stream_filter_t. stream_filer_t converts audio data in an input buffer and writes into another output buffer unlike sw_code, which converts data in single buffer. converters in dev/auconv.c, dev/mulaw.c, dev/aurateconv.c, dev/tc/bba.c, dev/ic/msm6258.c, and arch/arm/iomd/vidcaudio.c are reimplemented as stream_filter_t * MI audio - audiosetinfo() builds filter pipelines from stream_filter_list_t filled by audio_hw_if::set_params() - audiosetinfo() returns with EINVAL if mmapped and set_params() requests filters - audio_write(), audio_pint(), and audio_rint() invoke a filter pipeline. - ioctl() for FIONREAD, AUDIO_WSEEK, AUDIO_GETIOFFS, AUDIO_GETOOFFS, and audio_prinfo::{seek,samples} for AUDIO_GETINFO handle values for a buffer nearest to userland. * add `struct device ' parameter to ac97_attach() all of audio HW drivers follow audio_hw_if and ac97 changes
1.27	22-Apr-2002	augustss	branches: 1.27.10; 1.27.14; Rename the audio "bus" attribute audiobus to avoid confusion with audio device.
1.26	28-Nov-2001	lukem	- convert usage of "defopt" to "defflag" where the relevant option does not support a value (e.g., it's to be used as "options FOO" instead of "options FOO=xxx"). options that take a value were converted to defparam recently. - minor whitespace & formatting cleanups
1.25	01-Oct-2001	simonb	Move asc_tc and asc_tcds config info to dev/tc/files.tc now that pmax uses MI SCSI.
1.24	18-Sep-2001	ad	Beef up the stic X interface, and tighten a few screws here and there.
1.23	26-Aug-2001	simonb	branches: 1.23.2; Switch to MI SCSI and drop old pmax MD SCSI support completely.
1.22	16-Jan-2001	nisimura	branches: 1.22.2; 1.22.4; Add a definition for PMAGD which should cover all (three?) variations of it. Left commented out until DECstation switchs to WSCONS.
1.21	01-Jan-2001	mrg	the tcds cards work in pmaxen. move tcds attachment to files.tc. leave asc at tcds in files.alpha for now, and add a new `xasc at tcds' to files.pmax. after pmax has moved fully to MI scsi (and `asc' is MI scsi), we should move the device asc, etc., lines to files.tc.
1.20	17-Dec-2000	ad	Add wscons drivers for the DEC PixelStamp graphics accelerators.
1.19	24-Nov-2000	nisimura	Add TC option card descriptions, which are commented out before NetBSD/pmax yields local implementations to them.
1.18	02-May-2000	augustss	Add am7930 audio driver.
1.17	09-Sep-1999	nisimura	branches: 1.17.2; Use bus_dmamap_load() to obtain 128KB chunk for LANCE merging codes from NetBSD/alpha. Tested ok with DEC3000 and DECstation.
1.16	13-Apr-1999	ad	Removed pending write of fully-functional MI driver.
1.15	16-Mar-1999	simonb	branches: 1.15.4; Uncomment ioasic_subr.c.
1.14	15-Mar-1999	jonathan	MI ioasic softc and child-device structs, gc duplicate struct definitions. Add MI ioasic functions, but dont enable on alpha until tested.
1.13	21-Jul-1998	drochner	adapt to LANCE driver split
1.12	16-Feb-1998	thorpej	Remove "class" declarations, and add "devclass" declarations where appropriate. Fix several inconsistencies between device class and attributes. Mostly from Chris Demetriou.
1.11	12-Jan-1998	thorpej	Adjust for changes in config.
1.10	08-Nov-1997	jonathan	Commit `pacifier' driver for turbochannel PMAG-C option card:n just acknowledge interrupts from the PMAG-C.
1.9	13-Sep-1997	enami	branches: 1.9.2; Declare TCVERBOSE by defopt in files.tc. Include opt_tcverbose.h in tc.c.
1.8	22-Jul-1997	jonathan	branches: 1.8.2; Create sys/dev/dec and cleanup sys/dev/tc: * Move clockvar.h (header file for generic clock code) to sys/dev/dec. * Move if_le_dec.c with DEC padded LANCE-dma (pmax/pmax, ioasic, vax 3400) to sys/dev/dec. Remove from sys/dev/tc. * Declare attribute le_dec_subr in /sys/dev/dec/files.dec, use if_le_dec.c when it's defined. * Move IOCTL asic declaration from pmax and Alpha MD machine files to sys/dev/tc/files.tc. * move TurboChannel and ioasic if_le attachments from pmax and Alpha machine config files to /sys/dev/tc/files.tc. Add le_dec_subr attribute. * Add if_le_dec attribute to if_le_ibus (pmax ds3100 pmax) LANCE attachment.
1.7	20-Jul-1997	pk	config.new => config
1.6	15-Mar-1997	is	New ARP system, supports IPv4 over any hardware link. Some of the stuff (e.g., rarpd, bootpd, dhcpd etc., libsa) still will only support Ethernet. Tcpdump itself should be ok, but libpcap needs lot of work. For the detailed change history, look at the commit log entries for the is-newarp branch.
1.5	20-May-1996	thorpej	branches: 1.5.8; Add the DEFTA FDDI controller.
1.4	07-May-1996	thorpej	Make the MI LANCE driver standalone, and use cfattach to resolve naming conflicts between bus attachments on ports that can have multiple instances of the LANCE. Changed struct ifnet to have a pointer to the softc of the underlying device and a printable "external name" (name + unit number), thus eliminating if_name and if_unit. Updated interface to (if_watchdog)() and (if_reset)() to take a struct ifnet *, rather than a unit number.
1.3	17-Mar-1996	thorpej	New device attachment scheme: - split softc size and match/attach out from cfdriver into a new struct cfattach. - new "attach" directive for files.*. May specify the name of the cfattach structure, so that devices may be easily attached to parents with different autoconfiguration semantics.
1.2	27-Feb-1996	cgd	tcbus attribute moved to conf/files
1.1	20-Dec-1995	cgd	files file to define 'tcbus' attribute, to which 'tc's attach. also defines tc device. does _not_ define le driver, because of conflicts with other (e.g. ISA) le drivers. (Alpha kernel configuration files include files.isa and files.tc.)

1.10	07-May-1996	thorpej	Make the MI LANCE driver standalone, and use cfattach to resolve naming conflicts between bus attachments on ports that can have multiple instances of the LANCE. Changed struct ifnet to have a pointer to the softc of the underlying device and a printable "external name" (name + unit number), thus eliminating if_name and if_unit. Updated interface to (if_watchdog)() and (if_reset)() to take a struct ifnet *, rather than a unit number.
1.9	22-Apr-1996	christos	Add a hardware dependent initialization function lehwinit()
1.8	18-Apr-1996	cgd	restructure to take advantage of config's (relatively) new 'attach' specifiers. Many #ifdefs and much other nastiness removed.
1.7	18-Apr-1996	cgd	change LANCE copy & zero functions' names to start with amd7990_, and remove their 'integrate' (usually defined to be 'static') keywords. when lance drivers are split up by attachment, more than one file will reference the copy/zero functions (i.e. not just the file that pulls in am7990.c... and eventually inclusion of am7990.c should go away entirely).
1.6	08-Apr-1996	jonathan	fixes for -Wall -Wmissing-prototypes: prototype the forward declaration of lewritereg().
1.5	26-Mar-1996	jonathan	Fixup after the "New device attachment scheme": change {mainbus,tc,ioasic}cd to {mainbus,tc,ioasic}_cd. Change ioasic config name from "lance " to "lance". Correct for pmaxes, perhaps not for Alphas. Boots and runs under load on a 5000/200. Hangs during boot on an ioasic decstation; pmax autoconfig needs fixing. Add Decstation-3100 baseboard support (untested).
1.4	17-Mar-1996	thorpej	New device attachment scheme: - split softc size and match/attach out from cfdriver into a new struct cfattach. - new "attach" directive for files.*. May specify the name of the cfattach structure, so that devices may be easily attached to parents with different autoconfiguration semantics.
1.3	26-Feb-1996	cgd	(1) rename some structures & structure members, for consistency with planned changes in other sections of code. (2) expands the use of config_found() in tcattach() in-line, so that tcsubmatch can be invoked there, rather than being invoked by individual drivers. (3) tcbus_attach_args now includes a turbochannel speed flag. (4) compare a string in tcbus_attach_args against tc bus driver name, to better allow attachment of multiple busses to the same parent.
1.2	01-Feb-1996	jonathan	Set sc->sc_cookie appropriately for the ioasic and TC option cases. Tested on Decstation: ioasic, kn02 baseboard, and TC option card. Add untested for pmax 3100/5100 baseboard ethernet.
1.1	20-Dec-1995	cgd	Machine-independent TurboChannel LANCE driver. As-is, this driver should work properly with: (1) LANCE chips hanging off the system IOCTL asic, (2) LANCE chips TurboChannel option boards. Support for various PMAX-family baseboard options isn't yet in this file, but should be easy to add.
1.8	22-Jul-1997	jonathan	Create sys/dev/dec and cleanup sys/dev/tc: * Move clockvar.h (header file for generic clock code) to sys/dev/dec. * Move if_le_dec.c with DEC padded LANCE-dma (pmax/pmax, ioasic, vax 3400) to sys/dev/dec. Remove from sys/dev/tc. * Declare attribute le_dec_subr in /sys/dev/dec/files.dec, use if_le_dec.c when it's defined. * Move IOCTL asic declaration from pmax and Alpha MD machine files to sys/dev/tc/files.tc. * move TurboChannel and ioasic if_le attachments from pmax and Alpha machine config files to /sys/dev/tc/files.tc.

This is mandatory for some archs. See, e.g.: http://www.nerv.org/netbsd/?q=id:20210511T013030Z.013443cc790088147e4beed43f53dedabeaf9312 http://www.nerv.org/netbsd/?q=id:20220511T172220Z.561179f0b6fcc5b9cd73e274f69d74e2ce9e4c93 For some drivers, resource leaks for error paths are fixed at the same time. XXX XXX XXX Compile test only (at least one arch per driver).
1.34	03-Sep-2018	riastradh	Rename min/max -> uimin/uimax for better honesty. These functions are defined on unsigned int. The generic name min/max should not silently truncate to 32 bits on 64-bit systems. This is purely a name change -- no functional change intended. HOWEVER! Some subsystems have #define min(a, b) ((a) < (b) ? (a) : (b)) #define max(a, b) ((a) > (b) ? (a) : (b)) even though our standard name for that is MIN/MAX. Although these may invite multiple evaluation bugs, these do _not_ cause integer truncation. To avoid `fixing' these cases, I first changed the name in libkern, and then compile-tested every file where min/max occurred in order to confirm that it failed -- and thus confirm that nothing shadowed min/max -- before changing it. I have left a handful of bootloaders that are too annoying to compile-test, and some dead code: cobalt ews4800mips hp300 hppa ia64 luna68k vax acorn32/if_ie.c (not included in any kernels) macppc/if_gm.c (superseded by gem(4)) It should be easy to fix the fallout once identified -- this way of doing things fails safe, and the goal here, after all, is to _avoid_ silent integer truncations, not introduce them. Maybe one day we can reintroduce min/max as type-generic things that never silently truncate. But we should avoid doing that for a while, so that existing code has a chance to be detected by the compiler for conversion to uimin/uimax without changing the semantics until we can properly audit it all. (Who knows, maybe in some cases integer truncation is actually intended!)

Adjust all call sites: - Simplify wherever possible; don't pass along arguments that aren't actually needed. - Don't be explicit about what interface attribute is attaching if the device only has one. (More simplification.) - Add a config_probe() function to be used in indirect configuiration situations, making is visibly easier to see when indirect config is in play, and allowing for future change in semantics. (As of now, this is just a wrapper around config_match(), but that is an implementation detail.) Remove unnecessary or redundant interface attributes where they're not needed. There are currently 5 "cfargs" defined: - CFARG_SUBMATCH (submatch function for direct config) - CFARG_SEARCH (search function for indirect config) - CFARG_IATTR (interface attribte) - CFARG_LOCATORS (locators array) - CFARG_DEVHANDLE (devhandle_t - wraps OFW, ACPI, etc. handles) ...and a sentinel value CFARG_EOL. Add some extra sanity checking to ensure that interface attributes aren't ambiguous. Use CFARG_DEVHANDLE in MI FDT, OFW, and ACPI code, and macppc and shark ports to associate those device handles with device_t instance. This will trickle trough to more places over time (need back-end for pre-OFW Sun OBP; any others?).

1.1	17-Apr-1996	cgd	clean up clock handling: clock drivers are now seperate from the chip-independent clock code. 'clock' has been renamed 'mcclock' 'clock' has been renamed 'mcclock' (since it's a driver for that particular clock, and since eventually there may be another clock chip driver), and now attaches via seperate match/attach functions to both TC and ISA. This removes a whole lot of #ifdefs...
1.2.2.1	01-Jun-1997	cgd	sync the nwscons branch up with yesterday's version of the trunk. Lots of conflicts/changes because of the RCS Id format changes. Also, a few cleanups and corrections.

1.63	07-Aug-2021	thorpej	Merge thorpej-cfargs2.
1.62	24-Apr-2021	thorpej	branches: 1.62.8; Merge thorpej-cfargs branch: Simplify and make extensible the config_search() / config_found() / config_attach() interfaces: rather than having different variants for which arguments you want pass along, just have a single call that takes a variadic list of tag-value arguments. Adjust all call sites: - Simplify wherever possible; don't pass along arguments that aren't actually needed. - Don't be explicit about what interface attribute is attaching if the device only has one. (More simplification.) - Add a config_probe() function to be used in indirect configuiration situations, making is visibly easier to see when indirect config is in play, and allowing for future change in semantics. (As of now, this is just a wrapper around config_match(), but that is an implementation detail.) Remove unnecessary or redundant interface attributes where they're not needed.

The driver cannot guess this by itself but it is needed to implement, at least, the getwschar and putwschar functions in the correct place. There are no functional changes yet.

1.39	13-Nov-2003	chs	eliminate uvm_useracc() in favor of checking the return value of copyin() or copyout(). uvm_useracc() tells us whether the mapping permissions allow access to the desired part of an address space, and many callers assume that this is the same as knowing whether an attempt to access that part of the address space will succeed. however, access to user space can fail for reasons other than insufficient permission, most notably that paging in any non-resident data can fail due to i/o errors. most of the callers of uvm_useracc() make the above incorrect assumption. the rest are all misguided optimizations, which optimize for the case where an operation will fail. we'd rather optimize for operations succeeding, in which case we should just attempt the access and handle failures due to insufficient permissions the same way we handle i/o errors. since there appear to be no good uses of uvm_useracc(), we'll just remove it.

ERESTART has been moved to -3 and EPASSTHROUGH has been placed at -4. No ioctl code should now return -1 anywhere. The ioctl() system call is now properly restartable.
1.31	13-Mar-2002	ad	Reorganise the wsfont stuff slightly so that multiple display adapters with different bit/byte order requirements can co-exist happily.

1.23	26-Jun-2000	simonb	Change the kernel mmap interface so that the offset to map is an "off_t" and the return value is a "paddr_t" to allow mappings at offsets past 2^31 bytes. Somewhat inspired by FreeBSD, which only changed the offset to a "vm_offset_t". Includes updates for the i386, pc532 and sh3 mmmmap from Jason Thorpe.

1.14	24-Jun-1999	nisimura	- Hide memory mapped VDAC hardware register layouts using the array element access instead of C bitfield (hello, BCPL). - XXX Some TURBOchannel framebuffers might need shutdownhooks(). It seems not necessarily hardware sprite cursor images are re-initialized by DECstation PROMs upon exits from kernel. - XXX It'd be an arguable point to allow user programs to change the shade of gray freely for pixel value 0 and 1.
1.13	23-Jun-1999	nisimura	- Allow to choose the 'color' of sprite cursor. Only red cmap makes sense. - Drop TC Alpha support (OSF/1 and Digital UNIX never supports PMAG-AA).
1.12	23-Jun-1999	nisimura	- Fix an error in the depth of PMAG-AA MX. This driver can take 72Hz virtical video retrace interrupt and was verified ok on Nanao grayscale monitor. XXX seems still confusion/mistake on Bt431 cursor image manipulation.
1.11	07-May-1999	nisimura	- Sweep abit preparing for code merge to have common 'vdacops' across various graphics cards.
1.10	29-Mar-1999	nisimura	branches: 1.10.4; - Unnecessary to have '#include <machine/autoconf.h>' for those.
1.9	24-Mar-1999	mrg	completely remove Mach VM support. all that is left is the all the header files as UVM still uses (most of) these.
1.8	15-Jan-1999	thorpej	__pmax__ -> pmax, like other ports.
1.7	11-Jan-1999	drochner	remove dummy "load_font" entries
1.6	14-Dec-1998	nisimura	- Fix typos in commentary description.
1.5	19-Nov-1998	mrg	fix problems in many d_mmap routines: - returned EOPNOTSUPP rather than -1. - no check for negative offset. many of these fix potential security problems in these drivers. XXX XXX XXX the d_mmap cdev routine should be changed to have a prototype like: paddr_t (*d_mmap) __P((dev_t, off_t, int)); by someone!
1.4	18-Nov-1998	nisimura	- Fix cursor image handling bugs escaped in last commit.
1.3	09-Nov-1998	nisimura	- Fix many errors in cursor image manipulation. Hardware expect 2 bit/pixel format, not planer format. Assign MSB for cursor mask and LSB for cursor image, where 10 means mask color and 11 for image color. Image bit order of Bt431 and Bt459 are opposite to MIPS/Alpha processors while IMS G332 and DC503 (PCC) are indentical. - Assume that cursor images are 32 pixel padded as ULTRIX/DU ws interface do. It's natural to X server. - XXX Vast majority of codes are duplicated between mfb<->tfb and cfb<->sfb. Code sharing might be achieved in the context of TGA/SFB+ merge.
1.2	30-Oct-1998	nisimura	- Assign copyright terms.
1.1	29-Oct-1998	nisimura	- Introduce MI NWSCONS drivers for TURBOchannel framebuffer option cards. N.B., Digital UNIX never supports neither PMAG-AA (mfb) nor PMAG-BA (cfb) for TC Alphas. PMAG-DV (xcfb) is Personal DECstation built in. All should be good for console, but need much works for cursor/colormap completeness.

1.37	20-Jul-2022	thorpej	In the Alpha tc_syncbus(), we need to issue a MB because WMB does not order reads with respect to writes. Remove now-redundant tc_wmb() calls before tc_syncbus(). NFC on MIPS other than removing a redundant wbflush() (tc_wmb() followed by tc_syncbus()).
1.36	10-Nov-2019	chs	in many device attach paths, allocate memory with M_WAITOK instead of M_NOWAIT and remove code to handle failures that can no longer happen.

1.88	07-Aug-2021	thorpej	Merge thorpej-cfargs2.
1.87	24-Apr-2021	thorpej	branches: 1.87.8; Merge thorpej-cfargs branch: Simplify and make extensible the config_search() / config_found() / config_attach() interfaces: rather than having different variants for which arguments you want pass along, just have a single call that takes a variadic list of tag-value arguments. Adjust all call sites: - Simplify wherever possible; don't pass along arguments that aren't actually needed. - Don't be explicit about what interface attribute is attaching if the device only has one. (More simplification.) - Add a config_probe() function to be used in indirect configuiration situations, making is visibly easier to see when indirect config is in play, and allowing for future change in semantics. (As of now, this is just a wrapper around config_match(), but that is an implementation detail.) Remove unnecessary or redundant interface attributes where they're not needed. There are currently 5 "cfargs" defined: - CFARG_SUBMATCH (submatch function for direct config) - CFARG_SEARCH (search function for indirect config) - CFARG_IATTR (interface attribte) - CFARG_LOCATORS (locators array) - CFARG_DEVHANDLE (devhandle_t - wraps OFW, ACPI, etc. handles) ...and a sentinel value CFARG_EOL. Add some extra sanity checking to ensure that interface attributes aren't ambiguous. Use CFARG_DEVHANDLE in MI FDT, OFW, and ACPI code, and macppc and shark ports to associate those device handles with device_t instance. This will trickle trough to more places over time (need back-end for pre-OFW Sun OBP; any others?).

The driver cannot guess this by itself but it is needed to implement, at least, the getwschar and putwschar functions in the correct place. There are no functional changes yet.

1.62	17-Dec-2003	ad	- Restore the display to a sane state when leaving mapped mode. - OR updates into sc_changed, and protect with spltty()/splx().
1.61	13-Nov-2003	chs	eliminate uvm_useracc() in favor of checking the return value of copyin() or copyout(). uvm_useracc() tells us whether the mapping permissions allow access to the desired part of an address space, and many callers assume that this is the same as knowing whether an attempt to access that part of the address space will succeed. however, access to user space can fail for reasons other than insufficient permission, most notably that paging in any non-resident data can fail due to i/o errors. most of the callers of uvm_useracc() make the above incorrect assumption. the rest are all misguided optimizations, which optimize for the case where an operation will fail. we'd rather optimize for operations succeeding, in which case we should just attempt the access and handle failures due to insufficient permissions the same way we handle i/o errors. since there appear to be no good uses of uvm_useracc(), we'll just remove it.

1.39	25-Nov-2000	nisimura	Replace sfb_copycols() which can run better job in some degree. It still fails on certain conditions, thus is left commented out. copycols() is done by a generic routine which works correctly.
1.38	27-Oct-2000	nisimura	Fix errors in initializing the software copy of 256 entry colormap stored in device softc. rasops_cmap[] array is orginazed in 256 iteration of 3 byte long RBG triplet, which does not match with struct wsdisplay_cmap design.
1.37	28-Jun-2000	mrg	remove include of <vm/vm.h>. <vm/vm.h> -> <uvm/uvm_extern.h>
1.36	26-Jun-2000	simonb	Change the kernel mmap interface so that the offset to map is an "off_t" and the return value is a "paddr_t" to allow mappings at offsets past 2^31 bytes. Somewhat inspired by FreeBSD, which only changed the offset to a "vm_offset_t". Includes updates for the i386, pc532 and sh3 mmmmap from Jason Thorpe.
1.35	16-Mar-2000	nisimura	branches: 1.35.4; Retain rendering performance lossage by rasops, but suffering flexibility in turn; this renderer is 2B stroke (less than 16 pixel width) font only. If 1B stroke (less than 8 pixel width) font is ever supported, the font data should be converted into 2B stroke during font initialization process. 'wsfont_realize()' is to be proposed in order to have 'CPU and/or accelerator hardware friendly' format to squeeze maxinum performance.
1.34	18-Feb-2000	nisimura	Improvement on SFB enabled copycol(); still yet under development, it miserably fails on corner cases.
1.33	07-Jan-2000	enami	Replace WSFONT_L2R/R2L with WSDISPLAY_FONTORDER_L2R/R2L.
1.32	16-Dec-1999	ad	Remove part of a bogus comment and put it in a more appropiate spot.
1.31	15-Dec-1999	ad	- Change prefix for Bt459 register defs to BT459_IREG to indicate that these are indirectly accessed registers. - Add defs for directly accessed registers to bt459reg.h.
1.30	06-Dec-1999	drochner	update for changed struct wsdisplay_accessops:show_screen signature. no functional changes
1.29	04-Dec-1999	drochner	some cleanup: -don't set capabilities at compile time -since our accelerated putchar() doesn't underline, don't claim so -remove bogus character range check - fonts are not limited to ASCII -use rasops_unpack_attr() instead of relying on rasops internals
1.28	02-Dec-1999	drochner	Convert to use rasops/wsfont, enabling colors. For now, only the "putchar" and "copyrows" accelerations are used.
1.27	29-Nov-1999	nisimura	Const poisoning.
1.26	09-Nov-1999	nisimura	Fix errors in sfb_copycols() of the forward (left-to-right) case.
1.25	05-Nov-1999	nisimura	- Remove temporary hack to recognize PMAGD since SFB+ rendering function is found not fully upward compatible to its predecessor. sfbp.c is now under development. - Reduce copycols() malfunction, but has still lot of troubles.
1.24	27-Oct-1999	nisimura	Add a temporary kludge to recognize PMAGD (HX+) as 'sfb' hoping 8bpp configration of it is compatible enough with PMAGB-BA.
1.23	26-Oct-1999	nisimura	- Fix bogus cursor drawn by sfb_cursor(). From eye-opening input from R.C. Dowdeswell. - Remove write memory barriers in sfb_copyrows() as dst. is always distant enough from src. for copying rows.
1.22	22-Oct-1999	nisimura	Fill always erased regions with bg color. Fix an issue revealed by "print -n '\033[7m'; ls".
1.21	19-Oct-1999	nisimura	branches: 1.21.2; Preliminary import of 'SFB enhanced' text renderer with many caveats to be corrected. Text drawing is now improved significantly, but; cursor is drawn incorrectly, copycols() trashes a screen, 'standout (\033[7m)' results in lines reversed entirely until '\033[0m', and possibly more issues. Not multi-colour, 8bpp only this moment. Costly write memory barrier instrunctions should be eliminated using framebuffer address aliasing technique for NetBSD/alpha.
1.20	08-Oct-1999	nisimura	branches: 1.20.2; Arrange loop invariants and fix comment description error.
1.19	05-Oct-1999	nisimura	branches: 1.19.2; SFB video base register is assigned with an inialial value before use; according to ULTRIX/OSF1 code.
1.18	25-Jun-1999	nisimura	- Show 1bpp for MX during configuration stage. - Replace memory layout 'struct' with array/pointer access.
1.17	11-Jun-1999	nisimura	- Errors in case analysis...
1.16	11-Jun-1999	nisimura	- Rework copycols() with SFB ASIC calls.
1.15	07-May-1999	nisimura	- Sweep abit preparing for code merge to have common 'vdacops' across various graphics cards.
1.14	29-Mar-1999	nisimura	branches: 1.14.4; - Unnecessary to have '#include <machine/autoconf.h>' for those.
1.13	24-Mar-1999	mrg	completely remove Mach VM support. all that is left is the all the header files as UVM still uses (most of) these.
1.12	02-Mar-1999	nisimura	- Make sfb_emulops standard feature of sfb wscons. Scrolling is now acceptable. Still lacks of horizontal copy and glyph rendering with SFB ASIC assistance. TGA could be benefitted in the similiar way.
1.11	01-Mar-1999	nisimura	- Fix cursor image validity check error in set_cursor().
1.10	23-Feb-1999	nisimura	- Introduce the first cut of faster wsdisplay_emulops exploiting SFB accelerator potential. Need more work to finish replacing rcons. Premilinary tests were done with DECstation and TC Alpha.
1.9	19-Feb-1999	nisimura	- Make sure SFB ROP register initialized with value 3. - Turn off video signal during hardware initialization.
1.8	15-Jan-1999	thorpej	__pmax__ -> pmax, like other ports.
1.7	11-Jan-1999	drochner	remove dummy "load_font" entries
1.6	19-Nov-1998	mrg	fix problems in many d_mmap routines: - returned EOPNOTSUPP rather than -1. - no check for negative offset. many of these fix potential security problems in these drivers. XXX XXX XXX the d_mmap cdev routine should be changed to have a prototype like: paddr_t (*d_mmap) __P((dev_t, off_t, int)); by someone!
1.5	18-Nov-1998	nisimura	- Fix cursor image handling bugs escaped in last commit.
1.4	14-Nov-1998	drochner	use mi register definitions
1.3	09-Nov-1998	nisimura	- Fix many errors in cursor image manipulation. Hardware expect 2 bit/pixel format, not planer format. Assign MSB for cursor mask and LSB for cursor image, where 10 means mask color and 11 for image color. Image bit order of Bt431 and Bt459 are opposite to MIPS/Alpha processors while IMS G332 and DC503 (PCC) are indentical. - Assume that cursor images are 32 pixel padded as ULTRIX/DU ws interface do. It's natural to X server. - XXX Vast majority of codes are duplicated between mfb<->tfb and cfb<->sfb. Code sharing might be achieved in the context of TGA/SFB+ merge.
1.2	30-Oct-1998	nisimura	- Assign copyright terms.
1.1	29-Oct-1998	nisimura	- Introduce MI NWSCONS drivers for TURBOchannel framebuffer option cards. N.B., Digital UNIX never supports neither PMAG-AA (mfb) nor PMAG-BA (cfb) for TC Alphas. PMAG-DV (xcfb) is Personal DECstation built in. All should be good for console, but need much works for cursor/colormap completeness.

1.86.10.1	21-Mar-2021	thorpej	Give config_found() the same variadic arguments treatment as config_search(). This commit only adds the CFARG_EOL sentinel to the existing config_found() calls. Conversion of config_found_sm_loc() and config_found_ia() call sites will be in subsequent commits.
1.87.8.1	04-Aug-2021	thorpej	Adapt to CFARGS().
1.42	06-Dec-2021	abs	Add WSDISPLAYIO_GET_FBINFO support to sfbplus TURBOchannel framebuffer Missed in previous change to cfb, mfb, sfb, tfb and xcfb
1.41	07-Aug-2021	thorpej	Merge thorpej-cfargs2.
1.40	24-Apr-2021	thorpej	branches: 1.40.8; Merge thorpej-cfargs branch: Simplify and make extensible the config_search() / config_found() / config_attach() interfaces: rather than having different variants for which arguments you want pass along, just have a single call that takes a variadic list of tag-value arguments. Adjust all call sites: - Simplify wherever possible; don't pass along arguments that aren't actually needed. - Don't be explicit about what interface attribute is attaching if the device only has one. (More simplification.) - Add a config_probe() function to be used in indirect configuiration situations, making is visibly easier to see when indirect config is in play, and allowing for future change in semantics. (As of now, this is just a wrapper around config_match(), but that is an implementation detail.) Remove unnecessary or redundant interface attributes where they're not needed. There are currently 5 "cfargs" defined: - CFARG_SUBMATCH (submatch function for direct config) - CFARG_SEARCH (search function for indirect config) - CFARG_IATTR (interface attribte) - CFARG_LOCATORS (locators array) - CFARG_DEVHANDLE (devhandle_t - wraps OFW, ACPI, etc. handles) ...and a sentinel value CFARG_EOL. Add some extra sanity checking to ensure that interface attributes aren't ambiguous. Use CFARG_DEVHANDLE in MI FDT, OFW, and ACPI code, and macppc and shark ports to associate those device handles with device_t instance. This will trickle trough to more places over time (need back-end for pre-OFW Sun OBP; any others?).
1.39	10-Nov-2019	chs	branches: 1.39.10; in many device attach paths, allocate memory with M_WAITOK instead of M_NOWAIT and remove code to handle failures that can no longer happen.
1.38	24-Jan-2018	riastradh	branches: 1.38.4; Fix integer overflows noted by Silvio Cesare of InfoSect. Someone^TM should name these idioms so we can eliminate this class of copypasta bug.
1.37	11-Jan-2012	macallan	adjust wsfont_find()
1.36	13-Nov-2010	uebayasi	branches: 1.36.8; 1.36.12; Don't pull in the whole uvm(9) API to access only PAGE_SIZE and some other constants. These are provided by sys/param.h now.
1.35	15-May-2010	tsutsui	Clear RI_NO_AUTO in actual attach functions during autoconf(9) for console devices that set the flag during consinit().

1.27	04-Mar-2007	christos	Kill caddr_t; there will be some MI fallout, but it will be fixed shortly.
1.26	12-Apr-2006	jmmv	branches: 1.26.14; Add an extra cookie to the ioctl and mmap wsdisplay accessops that points to the screen on which they are being called. The driver cannot guess this by itself but it is needed to implement, at least, the getwschar and putwschar functions in the correct place. There are no functional changes yet. Tested on i386 (vga, vga_raster, machfb, vesafb), macppc and sparc64. Suggested and reviewed by macallan@.

1.19	13-Nov-2003	chs	eliminate uvm_useracc() in favor of checking the return value of copyin() or copyout(). uvm_useracc() tells us whether the mapping permissions allow access to the desired part of an address space, and many callers assume that this is the same as knowing whether an attempt to access that part of the address space will succeed. however, access to user space can fail for reasons other than insufficient permission, most notably that paging in any non-resident data can fail due to i/o errors. most of the callers of uvm_useracc() make the above incorrect assumption. the rest are all misguided optimizations, which optimize for the case where an operation will fail. we'd rather optimize for operations succeeding, in which case we should just attempt the access and handle failures due to insufficient permissions the same way we handle i/o errors. since there appear to be no good uses of uvm_useracc(), we'll just remove it.
1.18	02-Oct-2002	thorpej	branches: 1.18.6; Add trailing ; to CFATTACH_DECL.
1.17	01-Oct-2002	thorpej	Use CFATTACH_DECL().
1.16	19-Aug-2002	itohy	Leaving overflow-sensitive code, very similar to what was fixed in the previous changes to cfb.c / sfb.c / xcfb.c, would not be clever. Just modify in the similar way.
1.15	04-Jul-2002	junyoung	alloc_attr -> allocattr Approved by Matthias Drochner.
1.14	17-Mar-2002	atatat	branches: 1.14.4; Convert ioctl code to use EPASSTHROUGH instead of -1 or ENOTTY for indicating an unhandled "command". ERESTART is -1, which can lead to confusion. ERESTART has been moved to -3 and EPASSTHROUGH has been placed at -4. No ioctl code should now return -1 anywhere. The ioctl() system call is now properly restartable.
1.13	13-Mar-2002	ad	Reorganise the wsfont stuff slightly so that multiple display adapters with different bit/byte order requirements can co-exist happily.

1.9	27-Feb-2001	nisimura	branches: 1.9.2; 1.9.4; Change to exclude TC identification string PMAGD-AA because 8bpp can not be handled with current implementation. sfbplus.c should be capable of doing the right things for multiple depths by ultilizing SFB+ design.
1.8	17-Jan-2001	nisimura	managed to make this useful enough for screen editor. - video base register value brings different scanline starting address of framebuffer depending on VRAM chip column size. many other issues left unsolved. - text rendered in incorrect colours. - acceleration codes should be reimplemented from scratch.
1.7	16-Jan-2001	nisimura	- make this more senseful 32bpp TC framebuffer. This is far less broken than the preivous code. It can show readable characters on screen. Tested only with 32bpp model of PMAGD opion card. Need more work for 8bpp. - 2D accelleration will be revamped to ultilize SFBplus features. - there seems much mulfunctionness in 32bpp codes of /sys/dev/rasops/. Need to rectify every corners.
1.6	09-Sep-2000	nisimura	branches: 1.6.2; Use dev/{rasops,wsfont} instead of awesome dev/rcons. Still much to do before being useful.
1.5	28-Jun-2000	mrg	remove include of <vm/vm.h>. <vm/vm.h> -> <uvm/uvm_extern.h>
1.4	26-Jun-2000	simonb	Change the kernel mmap interface so that the offset to map is an "off_t" and the return value is a "paddr_t" to allow mappings at offsets past 2^31 bytes. Somewhat inspired by FreeBSD, which only changed the offset to a "vm_offset_t". Includes updates for the i386, pc532 and sh3 mmmmap from Jason Thorpe.
1.3	15-Dec-1999	ad	branches: 1.3.2; 1.3.6; - Change prefix for Bt459 register defs to BT459_IREG to indicate that these are indirectly accessed registers. - Add defs for directly accessed registers to bt459reg.h.

1.56	07-Aug-2021	thorpej	Merge thorpej-cfargs2.
1.55	24-Apr-2021	thorpej	branches: 1.55.8; Merge thorpej-cfargs branch: Simplify and make extensible the config_search() / config_found() / config_attach() interfaces: rather than having different variants for which arguments you want pass along, just have a single call that takes a variadic list of tag-value arguments. Adjust all call sites: - Simplify wherever possible; don't pass along arguments that aren't actually needed. - Don't be explicit about what interface attribute is attaching if the device only has one. (More simplification.) - Add a config_probe() function to be used in indirect configuiration situations, making is visibly easier to see when indirect config is in play, and allowing for future change in semantics. (As of now, this is just a wrapper around config_match(), but that is an implementation detail.) Remove unnecessary or redundant interface attributes where they're not needed. There are currently 5 "cfargs" defined: - CFARG_SUBMATCH (submatch function for direct config) - CFARG_SEARCH (search function for indirect config) - CFARG_IATTR (interface attribte) - CFARG_LOCATORS (locators array) - CFARG_DEVHANDLE (devhandle_t - wraps OFW, ACPI, etc. handles) ...and a sentinel value CFARG_EOL. Add some extra sanity checking to ensure that interface attributes aren't ambiguous. Use CFARG_DEVHANDLE in MI FDT, OFW, and ACPI code, and macppc and shark ports to associate those device handles with device_t instance. This will trickle trough to more places over time (need back-end for pre-OFW Sun OBP; any others?).

1.26	13-Nov-2003	chs	eliminate uvm_useracc() in favor of checking the return value of copyin() or copyout(). uvm_useracc() tells us whether the mapping permissions allow access to the desired part of an address space, and many callers assume that this is the same as knowing whether an attempt to access that part of the address space will succeed. however, access to user space can fail for reasons other than insufficient permission, most notably that paging in any non-resident data can fail due to i/o errors. most of the callers of uvm_useracc() make the above incorrect assumption. the rest are all misguided optimizations, which optimize for the case where an operation will fail. we'd rather optimize for operations succeeding, in which case we should just attempt the access and handle failures due to insufficient permissions the same way we handle i/o errors. since there appear to be no good uses of uvm_useracc(), we'll just remove it.

This merge changes the device switch tables from static array to dynamically generated by config(8). - All device switches is defined as a constant structure in device drivers. - The new grammer ``device-major'' is introduced to ``files''. device-major <prefix> char <num> [block <num>] [<rules>] - All device major numbers must be listed up in port dependent majors.<arch> by using this grammer. - Added the new naming convention. The name of the device switch must be <prefix>_[bc]devsw for auto-generation of device switch tables. - The backward compatibility of loading block/character device switch by LKM framework is broken. This is necessary to convert from block/character device major to device name in runtime and vice versa. - The restriction to assign device major by LKM is completely removed. We don't need to reserve LKM entries for dynamic loading of device switch. - In compile time, device major numbers list is packed into the kernel and the LKM framework will refer it to assign device major number dynamically.
1.19	19-Aug-2002	itohy	Leaving overflow-sensitive code, very similar to what was fixed in the previous changes to cfb.c / sfb.c / xcfb.c, would not be clever. Just modify in the similar way.
1.18	04-Jul-2002	junyoung	alloc_attr -> allocattr Approved by Matthias Drochner.
1.17	17-Mar-2002	atatat	branches: 1.17.4; Convert ioctl code to use EPASSTHROUGH instead of -1 or ENOTTY for indicating an unhandled "command". ERESTART is -1, which can lead to confusion. ERESTART has been moved to -3 and EPASSTHROUGH has been placed at -4. No ioctl code should now return -1 anywhere. The ioctl() system call is now properly restartable.

1.14	13-Nov-2003	chs	branches: 1.14.16; eliminate uvm_useracc() in favor of checking the return value of copyin() or copyout(). uvm_useracc() tells us whether the mapping permissions allow access to the desired part of an address space, and many callers assume that this is the same as knowing whether an attempt to access that part of the address space will succeed. however, access to user space can fail for reasons other than insufficient permission, most notably that paging in any non-resident data can fail due to i/o errors. most of the callers of uvm_useracc() make the above incorrect assumption. the rest are all misguided optimizations, which optimize for the case where an operation will fail. we'd rather optimize for operations succeeding, in which case we should just attempt the access and handle failures due to insufficient permissions the same way we handle i/o errors. since there appear to be no good uses of uvm_useracc(), we'll just remove it.

1.59	07-Aug-2021	thorpej	Merge thorpej-cfargs2.
1.58	07-May-2021	thorpej	branches: 1.58.6; A small bit of const poisoning.
1.57	24-Apr-2021	thorpej	branches: 1.57.2; Merge thorpej-cfargs branch: Simplify and make extensible the config_search() / config_found() / config_attach() interfaces: rather than having different variants for which arguments you want pass along, just have a single call that takes a variadic list of tag-value arguments. Adjust all call sites: - Simplify wherever possible; don't pass along arguments that aren't actually needed. - Don't be explicit about what interface attribute is attaching if the device only has one. (More simplification.) - Add a config_probe() function to be used in indirect configuiration situations, making is visibly easier to see when indirect config is in play, and allowing for future change in semantics. (As of now, this is just a wrapper around config_match(), but that is an implementation detail.) Remove unnecessary or redundant interface attributes where they're not needed. There are currently 5 "cfargs" defined: - CFARG_SUBMATCH (submatch function for direct config) - CFARG_SEARCH (search function for indirect config) - CFARG_IATTR (interface attribte) - CFARG_LOCATORS (locators array) - CFARG_DEVHANDLE (devhandle_t - wraps OFW, ACPI, etc. handles) ...and a sentinel value CFARG_EOL. Add some extra sanity checking to ensure that interface attributes aren't ambiguous. Use CFARG_DEVHANDLE in MI FDT, OFW, and ACPI code, and macppc and shark ports to associate those device handles with device_t instance. This will trickle trough to more places over time (need back-end for pre-OFW Sun OBP; any others?).
1.56	10-Jun-2017	flxd	branches: 1.56.22; Fix missing TC bus speed.
1.55	09-Jun-2017	flxd	Make VAXstation 4000 TURBOchannel adaptor work. PIO and IRQ tested on VS4000/60 and /96 with TC-USB (slhci) and PMAD-AA (le). DMA is untested. vax needs space to be mapped out, so memory space is pre-mapped for TC option drivers not bus_space'ified yet, also providing custom bus_space methods for this kludge.
1.54	12-Dec-2016	flxd	branches: 1.54.8; Clean-up (remove redundant declarations, concentrate checks).
1.53	19-Jul-2016	christos	make the check work with widths other than 4, Felix Deichmann
1.52	19-Jul-2016	christos	PR/50849: Felix Deichmann: Relax TC option ROM header check for ROM widths < 4
1.51	04-Jun-2011	tsutsui	branches: 1.51.12; 1.51.30; 1.51.34; Split device_t/softc. pmax is tested on GXemul. Compile test only for alpha and vax. XXX: alpha/tc/tcasic.c calls tcattach() via config_found(9), but XXX: pmax/tc/tcbus.c and vax/vsa/tc_vsbus.c calls tcattach() directly. XXX: It looks horrible...

1.43	11-Dec-2005	christos	branches: 1.43.4; 1.43.6; 1.43.8; 1.43.10; 1.43.12; merge ktrace-lwp.
1.42	26-Aug-2005	drochner	kill some more simple submatch() functions, use config_stdsubmatch()
1.41	25-Aug-2005	drochner	replace the "locdesc_t" structure carrying the number of locators explicitely by a plain integer array the length in now known to all relevant parties, so this avoids duplication of information, and we can allocate that thing in drivers without hacks
1.40	04-Feb-2005	perry	branches: 1.40.6; de-__P
1.39	26-Aug-2004	drochner	branches: 1.39.4; 1.39.6; some cleanup: use the locator-passing variant of config_found(), get the macros just hiding cfdata members out of tcvar.h and include "locators.h" only in the .c file
1.38	27-Apr-2004	yamt	remove redundant function prototypes to make this compilable after snprintf changes.
1.37	22-Apr-2004	itojun	sprintf -> snprintf
1.36	26-Sep-2003	tsutsui	Remove casts and use %x in printf for tc_offset_t, which is int32_t on both alpha and pmax.
1.35	01-Jan-2003	thorpej	branches: 1.35.2; Use aprint_normal() in cfprint routines.
1.34	02-Oct-2002	thorpej	Add trailing ; to CFATTACH_DECL.
1.33	01-Oct-2002	thorpej	Use CFATTACH_DECL().
1.32	27-Sep-2002	thorpej	Declare all cfattach structures const.
1.31	27-Sep-2002	thorpej	Introduce a new routine, config_match(), which invokes the cfattach->ca_match function in behalf of the caller. Use it rather than invoking cfattach->ca_match directly.
1.30	27-Sep-2002	thorpej	Rather than referencing the cfdriver directly in the cfdata entries, instead use a string naming the driver. The cfdriver is then looked up in a list which is built at run-time.
1.29	13-Nov-2001	lukem	add/cleanup RCSIDs
1.28	04-Jun-2000	cgd	branches: 1.28.4; 1.28.6; Implement the more flexiable `evcnt' interface as discussed (briefly) on tech-kern and now documented in evcnt(9).
1.27	15-Nov-1999	nisimura	branches: 1.27.2; Relocate 'struct tc_softc' and several function declarations useful to outsides of 'tc.c' into 'tcvar.h'.
1.26	22-May-1998	thorpej	branches: 1.26.14; 1.26.20; DECstation now provides bus_space and bus_dma data structures to us.
1.25	19-Jan-1998	thorpej	On the Alpha, pass down per-slot DMA tags to children.
1.24	12-Jan-1998	thorpej	Adjust for changes in config.
1.23	13-Sep-1997	enami	Declare TCVERBOSE by defopt in files.tc. Include opt_tcverbose.h in tc.c.
1.22	22-Jul-1997	jonathan	branches: 1.22.2; Garbage-collect __BROKEN_INDIRECT_CONFIG from /sys/dev/tc
1.21	05-Dec-1996	cgd	update these so they compile whether or not __BROKEN_INDIRECT_CONFIG is defined.
1.20	22-Oct-1996	cgd	update for new bus.h
1.19	13-Oct-1996	christos	backout kprintf changes
1.18	10-Oct-1996	christos	printf -> kprintf, sprintf -> ksprintf
1.17	27-Aug-1996	cgd	change cfprint_t type definition to take a const char , rather than a char , because that's what was really intended, and because if the print function modifies the string, various things could become unhappy (so the string should _not_ be modified).
1.16	17-May-1996	cgd	(on the alpha) pass the bus_chipset_tag_t given to the bus down to the devices.
1.15	29-Apr-1996	cgd	fix printf bogon (need : and space)
1.14	18-Apr-1996	cgd	remove unnecessary header inclusion (machine/autoconf.h) and now-bogus comment. also, trim spaces at ends of lines, etc.
1.13	09-Apr-1996	jonathan	Fixes for -Wall -Wmissing-prototypes: include <sys/systm.h> to get a prototyped declaration of printf(). include <machine/autoconf.h> for port-specific typedefs. Remove unused variables.
1.12	17-Mar-1996	jonathan	Additional fixes to complete the NetBSD/1.1B config changes: change tc_submatch() to compile with the new device-attach scheme: the TC bus uses a 'submatch' function which checks device locators and then calls a match function. Instead of calling cf->cf_driver->cd_match(), we now need to call cf->cf_attach->ca_match().
1.11	17-Mar-1996	thorpej	New device attachment scheme: - split softc size and match/attach out from cfdriver into a new struct cfattach. - new "attach" directive for files.*. May specify the name of the cfattach structure, so that devices may be easily attached to parents with different autoconfiguration semantics.
1.10	05-Mar-1996	cgd	split device info into driver name and human readable description.
1.9	02-Mar-1996	cgd	change printing of unknown device names when not (BUS)VERBOSE slightly
1.8	02-Mar-1996	cgd	add ability to define TCVERBOSE, and get "human names" about "known" but unconfigured (or unsupported) devices printed at boot time. The device list is woefully incomplete, because i didn't put much time in it, and because i don't know good "human names" for many TC devices.
1.7	27-Feb-1996	cgd	use config_found_sm(), rather than config_search+config_attach()+glue, to attach subdevices.
1.6	27-Feb-1996	cgd	fix first args in tcprint() invocations. Fix for this (and several previous commits) from Jonathan. This is why one (I) shouldn't commit code w/o having any sane way to test it.
1.5	27-Feb-1996	cgd	one more minor oops; print our name, not parent's, when doing unconfigured dev
1.4	27-Feb-1996	cgd	fix bug in previous commits. also, do submatch checking for all devices, not just option slot devices.
1.3	27-Feb-1996	cgd	use #defines for bus speed constants, print speed on attach
1.2	26-Feb-1996	cgd	(1) rename some structures & structure members, for consistency with planned changes in other sections of code. (2) expands the use of config_found() in tcattach() in-line, so that tcsubmatch can be invoked there, rather than being invoked by individual drivers. (3) tcbus_attach_args now includes a turbochannel speed flag. (4) compare a string in tcbus_attach_args against tc bus driver name, to better allow attachment of multiple busses to the same parent.
1.1	20-Dec-1995	cgd	machine-independent TurboChannel bus configuration. These files deal with stuff like: (1) configuring built-in devices, (2) looking at TC slots configuring any devices found. The lists of slots, slot locations, etc. and built-in devices are provided by machine-dependent code. Interrupt handling is also provided by machine-dependent code, but the MD code provides hooks so that standard names for 'establish' and 'disestablish' can be used in drivers. This code requires <machine/tc_machdep.h>, which defines some portability types specific to the TurboChannel bus code.

1.26.14.1	20-Nov-2000	bouyer	Update thorpej_scsipi to -current as of a month ago A i386 GENERIC kernel compiles without the siop, ahc and bha drivers (will be updated later). i386 IDE/ATAPI and ncr work, as well as sparc/esp_sbus. alpha should work as well (untested yet). siop, ahc and bha will be updated once I've updated the branch to current -current, as well as machine-dependant code.

1.28	07-Aug-2021	thorpej	Merge thorpej-cfargs2.
1.27	24-Apr-2021	thorpej	branches: 1.27.8; Merge thorpej-cfargs branch: Simplify and make extensible the config_search() / config_found() / config_attach() interfaces: rather than having different variants for which arguments you want pass along, just have a single call that takes a variadic list of tag-value arguments. Adjust all call sites: - Simplify wherever possible; don't pass along arguments that aren't actually needed. - Don't be explicit about what interface attribute is attaching if the device only has one. (More simplification.) - Add a config_probe() function to be used in indirect configuiration situations, making is visibly easier to see when indirect config is in play, and allowing for future change in semantics. (As of now, this is just a wrapper around config_match(), but that is an implementation detail.) Remove unnecessary or redundant interface attributes where they're not needed. There are currently 5 "cfargs" defined: - CFARG_SUBMATCH (submatch function for direct config) - CFARG_SEARCH (search function for indirect config) - CFARG_IATTR (interface attribte) - CFARG_LOCATORS (locators array) - CFARG_DEVHANDLE (devhandle_t - wraps OFW, ACPI, etc. handles) ...and a sentinel value CFARG_EOL. Add some extra sanity checking to ensure that interface attributes aren't ambiguous. Use CFARG_DEVHANDLE in MI FDT, OFW, and ACPI code, and macppc and shark ports to associate those device handles with device_t instance. This will trickle trough to more places over time (need back-end for pre-OFW Sun OBP; any others?).

These files deal with stuff like: (1) configuring built-in devices, (2) looking at TC slots configuring any devices found. The lists of slots, slot locations, etc. and built-in devices are provided by machine-dependent code. Interrupt handling is also provided by machine-dependent code, but the MD code provides hooks so that standard names for 'establish' and 'disestablish' can be used in drivers. This code requires <machine/tc_machdep.h>, which defines some portability types specific to the TurboChannel bus code.

1.5.8.1	04-Aug-2021	thorpej	Adapt to CFARGS().
1.28	07-May-2021	thorpej	A small bit of const poisoning.
1.27	09-Jun-2017	flxd	branches: 1.27.24; Make VAXstation 4000 TURBOchannel adaptor work. PIO and IRQ tested on VS4000/60 and /96 with TC-USB (slhci) and PMAD-AA (le). DMA is untested. vax needs space to be mapped out, so memory space is pre-mapped for TC option drivers not bus_space'ified yet, also providing custom bus_space methods for this kludge.
1.26	04-Jun-2011	tsutsui	branches: 1.26.12; 1.26.30; 1.26.46; Split device_t/softc. pmax is tested on GXemul. Compile test only for alpha and vax. XXX: alpha/tc/tcasic.c calls tcattach() via config_found(9), but XXX: pmax/tc/tcbus.c and vax/vsa/tc_vsbus.c calls tcattach() directly. XXX: It looks horrible...
1.25	20-Feb-2011	matt	branches: 1.25.2; Add some missing includes of <sys/device.h>
1.24	12-May-2009	cegger	branches: 1.24.4; 1.24.6; 1.24.8; struct device * -> device_t, no functional changes intended.

1.21	01-Jun-2005	drochner	branches: 1.21.2; fix cast-qual fallout
1.20	27-Feb-2005	perry	nuke trailing whitespace
1.19	26-Aug-2004	drochner	branches: 1.19.4; 1.19.6; some cleanup: use the locator-passing variant of config_found(), get the macros just hiding cfdata members out of tcvar.h and include "locators.h" only in the .c file
1.18	27-Apr-2004	yamt	remove redundant function prototypes to make this compilable after snprintf changes.
1.17	04-Jun-2000	cgd	branches: 1.17.26; Implement the more flexiable `evcnt' interface as discussed (briefly) on tech-kern and now documented in evcnt(9).
1.16	01-Jun-2000	cgd	kill __P in these files. (I had to look at them anyway with an eye for adding some protos... and adding them with __P seems wrong, but mixing __P and not __P in the same file seems wrong too, so...)
1.15	15-Nov-1999	nisimura	branches: 1.15.2; Relocate 'struct tc_softc' and several function declarations useful to outsides of 'tc.c' into 'tcvar.h'.
1.14	19-Mar-1999	cgd	branches: 1.14.8; 1.14.14; pull tc_machdep.h in from machine/
1.13	22-May-1998	thorpej	DECstation now provides bus_space and bus_dma data structures to us.
1.12	19-Apr-1998	jonathan	pmax has IPL_ constants; Define TC_IPL_ using them until all tc drivers are converted to use IPL_. Commit changes to if_le_ibus.c as a child of ibus.
1.11	19-Jan-1998	thorpej	Add "get this slot's DMA tag" function pointer on the Alpha.
1.10	12-Jan-1998	thorpej	Adjust for changes in config.
1.9	01-Sep-1997	jonathan	Remove '#ifdef alpha' around bus_space_tag_t uses and includes.
1.8	17-Jul-1997	jtk	branches: 1.8.2; use locator defines in "locators.h" to index cf_loc[] still to be done and/or decided not to be done: replace all TCCF_*_UNKNOWN uses in tc code with the native names from locators.h
1.7	22-Oct-1996	cgd	update for new bus.h
1.6	09-Sep-1996	cgd	add missing underscore to __alpha_, to map interrupt names properly. It worked right before because of happy coincidence.
1.5	17-May-1996	cgd	Update for new includes (<machine/bus.h> & <machine/intr.h>) on the alpha. At some point in the future, those headers should be provided on the pmax, but until then, things are #ifdef'd so that the old headers and definitions are still used. Pass a bus_chipset_tag_t to the TC bus attach code and to devices, on the alpha.
1.4	17-Mar-1996	jonathan	Additional fixes to complete the NetBSD/1.1B config changes: Rename the extern declaration of `tccd' and `ioasiccd' in src/sys/dev/tc/{tvar.h,ioasicvar.h", respectively, to be `tc_cd' and `ioasic_cd', to match the 1.1B-style definitions.
1.3	27-Feb-1996	cgd	use #defines for bus speed constants, print speed on attach
1.2	26-Feb-1996	cgd	(1) rename some structures & structure members, for consistency with planned changes in other sections of code. (2) expands the use of config_found() in tcattach() in-line, so that tcsubmatch can be invoked there, rather than being invoked by individual drivers. (3) tcbus_attach_args now includes a turbochannel speed flag. (4) compare a string in tcbus_attach_args against tc bus driver name, to better allow attachment of multiple busses to the same parent.
1.1	20-Dec-1995	cgd	machine-independent TurboChannel bus configuration. These files deal with stuff like: (1) configuring built-in devices, (2) looking at TC slots configuring any devices found. The lists of slots, slot locations, etc. and built-in devices are provided by machine-dependent code. Interrupt handling is also provided by machine-dependent code, but the MD code provides hooks so that standard names for 'establish' and 'disestablish' can be used in drivers. This code requires <machine/tc_machdep.h>, which defines some portability types specific to the TurboChannel bus code.
1.8.2.1	01-Sep-1997	thorpej	Update marc-pcmcia branch from trunk.
1.14.14.1	27-Dec-1999	wrstuden	Pull up to last week's -current.
1.14.8.1	20-Nov-2000	bouyer	Update thorpej_scsipi to -current as of a month ago A i386 GENERIC kernel compiles without the siop, ahc and bha drivers (will be updated later). i386 IDE/ATAPI and ncr work, as well as sparc/esp_sbus. alpha should work as well (untested yet). siop, ahc and bha will be updated once I've updated the branch to current -current, as well as machine-dependant code.

1.66	06-Dec-2021	abs	Add WSDISPLAYIO_GET_FBINFO support to most TURBOchannel framebuffers This adds WSDISPLAYIO_GET_FBINFO to cfb, mfb, sfb, tfb and xcfb TURBOchannel framebuffers as used by pmax and alpha It does not add support to px and pxg (they handle ioctls in common code in stic.c and more careful wiring is required) These changes allow an Xswfb X server to use the framebuffer directly, albeit without any special acceleration A subsequent change will re-enable X server building on pmax, and also hopefully switch alpha from Xorg 1.10 to 1.20
1.65	07-Aug-2021	thorpej	Merge thorpej-cfargs2.
1.64	24-Apr-2021	thorpej	branches: 1.64.8; Merge thorpej-cfargs branch: Simplify and make extensible the config_search() / config_found() / config_attach() interfaces: rather than having different variants for which arguments you want pass along, just have a single call that takes a variadic list of tag-value arguments. Adjust all call sites: - Simplify wherever possible; don't pass along arguments that aren't actually needed. - Don't be explicit about what interface attribute is attaching if the device only has one. (More simplification.) - Add a config_probe() function to be used in indirect configuiration situations, making is visibly easier to see when indirect config is in play, and allowing for future change in semantics. (As of now, this is just a wrapper around config_match(), but that is an implementation detail.) Remove unnecessary or redundant interface attributes where they're not needed. There are currently 5 "cfargs" defined: - CFARG_SUBMATCH (submatch function for direct config) - CFARG_SEARCH (search function for indirect config) - CFARG_IATTR (interface attribte) - CFARG_LOCATORS (locators array) - CFARG_DEVHANDLE (devhandle_t - wraps OFW, ACPI, etc. handles) ...and a sentinel value CFARG_EOL. Add some extra sanity checking to ensure that interface attributes aren't ambiguous. Use CFARG_DEVHANDLE in MI FDT, OFW, and ACPI code, and macppc and shark ports to associate those device handles with device_t instance. This will trickle trough to more places over time (need back-end for pre-OFW Sun OBP; any others?).
1.63	10-Nov-2019	chs	branches: 1.63.10; in many device attach paths, allocate memory with M_WAITOK instead of M_NOWAIT and remove code to handle failures that can no longer happen.
1.62	24-Jan-2018	riastradh	branches: 1.62.4; Fix integer overflows noted by Silvio Cesare of InfoSect. Someone^TM should name these idioms so we can eliminate this class of copypasta bug.
1.61	11-Jan-2012	macallan	adjust wsfont_find()
1.60	13-Nov-2010	uebayasi	branches: 1.60.8; 1.60.12; Don't pull in the whole uvm(9) API to access only PAGE_SIZE and some other constants. These are provided by sys/param.h now.
1.59	15-May-2010	tsutsui	Clear RI_NO_AUTO in actual attach functions during autoconf(9) for console devices that set the flag during consinit().
1.58	15-May-2010	tsutsui	Set RI_NO_AUTO in ri_flg if *fb_common_init() is invoked from cnattach. Untested.
1.57	22-Aug-2009	tsutsui	branches: 1.57.2; 1.57.4; u_intNN_t -> uintNN_t
1.56	17-Dec-2008	cegger	kill MALLOC and FREE macros.
1.55	09-Jul-2008	joerg	branches: 1.55.2; - device/softc split - make sfbplus at least compilable
1.54	26-May-2008	nisimura	branches: 1.54.2; 1.54.4; - assign 2 clause TNF license to the files cited as my ownership. - abandon and remove my copyright notice from the three files were copied in order to adapt HW I don't have; pvr.c, pm.c and stic.c
1.53	19-Oct-2007	ad	branches: 1.53.16; 1.53.18; 1.53.20; 1.53.22; machine/{bus,cpu,intr}.h -> sys/{bus,cpu,intr}.h

1.51	04-Mar-2007	christos	Kill caddr_t; there will be some MI fallout, but it will be fixed shortly.
1.50	12-Apr-2006	jmmv	branches: 1.50.14; Add an extra cookie to the ioctl and mmap wsdisplay accessops that points to the screen on which they are being called. The driver cannot guess this by itself but it is needed to implement, at least, the getwschar and putwschar functions in the correct place. There are no functional changes yet. Tested on i386 (vga, vga_raster, machfb, vesafb), macppc and sparc64. Suggested and reviewed by macallan@.
1.49	31-Mar-2006	thorpej	Use ANSI function decls, apply static.
1.48	30-Mar-2006	thorpej	Use device_private().
1.47	11-Dec-2005	christos	branches: 1.47.4; 1.47.6; 1.47.8; 1.47.10; 1.47.12; merge ktrace-lwp.

1.44	20-Dec-2003	nisimura	- Minor coding modifications for VDAC register access. - De-__P() this time. Tested valid with 4MAXINE.
1.43	17-Dec-2003	ad	- Restore the display to a sane state when leaving mapped mode. - OR updates into sc_changed, and protect with spltty()/splx().
1.42	13-Nov-2003	chs	eliminate uvm_useracc() in favor of checking the return value of copyin() or copyout(). uvm_useracc() tells us whether the mapping permissions allow access to the desired part of an address space, and many callers assume that this is the same as knowing whether an attempt to access that part of the address space will succeed. however, access to user space can fail for reasons other than insufficient permission, most notably that paging in any non-resident data can fail due to i/o errors. most of the callers of uvm_useracc() make the above incorrect assumption. the rest are all misguided optimizations, which optimize for the case where an operation will fail. we'd rather optimize for operations succeeding, in which case we should just attempt the access and handle failures due to insufficient permissions the same way we handle i/o errors. since there appear to be no good uses of uvm_useracc(), we'll just remove it.
1.41	27-Oct-2003	chs	uninitialized variables
1.40	29-Jun-2003	fvdl	branches: 1.40.2; Back out the lwp/ktrace changes. They contained a lot of colateral damage, and need to be examined and discussed more.
1.39	29-Jun-2003	simonb	Fix 'struct lwp *' lossage.
1.38	02-Oct-2002	thorpej	Add trailing ; to CFATTACH_DECL.
1.37	01-Oct-2002	thorpej	Use CFATTACH_DECL().
1.36	19-Aug-2002	itohy	Leaving overflow-sensitive code, very similar to what was fixed in the previous changes to cfb.c / sfb.c / xcfb.c, would not be clever. Just modify in the similar way.
1.35	04-Jul-2002	junyoung	alloc_attr -> allocattr Approved by Matthias Drochner.
1.34	17-Mar-2002	atatat	branches: 1.34.4; Convert ioctl code to use EPASSTHROUGH instead of -1 or ENOTTY for indicating an unhandled "command". ERESTART is -1, which can lead to confusion. ERESTART has been moved to -3 and EPASSTHROUGH has been placed at -4. No ioctl code should now return -1 anywhere. The ioctl() system call is now properly restartable.
1.33	13-Mar-2002	ad	Reorganise the wsfont stuff slightly so that multiple display adapters with different bit/byte order requirements can co-exist happily.
1.32	13-Nov-2001	lukem	add/cleanup RCSIDs
1.31	22-Aug-2001	nisimura	Nuke fb_devconfig data structure which was found unnecessary to have.

1.29	16-Jan-2001	nisimura	branches: 1.29.2; 1.29.4; - relocate the code to place sprite cursor inside interrupt handlers called on every virtical replace. - efforts to make the code strucutures similar across TC framebuffers.
1.28	27-Oct-2000	nisimura	Fix errors in initializing the software copy of 256 entry colormap stored in device softc. rasops_cmap[] array is orginazed in 256 iteration of 3 byte long RBG triplet, which does not match with struct wsdisplay_cmap design.
1.27	13-Sep-2000	nisimura	Found glyph pixel order inverted on screen.
1.26	28-Jun-2000	mrg	remove include of <vm/vm.h>. <vm/vm.h> -> <uvm/uvm_extern.h>
1.25	26-Jun-2000	simonb	Change the kernel mmap interface so that the offset to map is an "off_t" and the return value is a "paddr_t" to allow mappings at offsets past 2^31 bytes. Somewhat inspired by FreeBSD, which only changed the offset to a "vm_offset_t". Includes updates for the i386, pc532 and sh3 mmmmap from Jason Thorpe.
1.24	16-Mar-2000	nisimura	branches: 1.24.4; Place 34 by 80 console at the center of screen.
1.23	14-Mar-2000	nisimura	Respect video console colour designation by configration file.
1.22	14-Mar-2000	nisimura	Switch to improved flexible video console text rasterizer provided by rasops and wsfont.
1.21	06-Dec-1999	drochner	update for changed struct wsdisplay_accessops:show_screen signature. no functional changes
1.20	29-Nov-1999	nisimura	Const poisoning.
1.19	19-Oct-1999	nisimura	branches: 1.19.2; Enable 'WSSCREEN_REVERSE' scr-capability.
1.18	20-Sep-1999	nisimura	branches: 1.18.2; 1.18.4; Add one new dispaly type for DEC TC TX 8/24bpp framebuffer. Currently acts as an 8bpp pseudo color device.
1.17	25-Aug-1999	nisimura	- Fix an error in cursor image manipulation. I learned a pair of Bt431 were populated in reverse order from PMAG-A MX ...
1.16	25-Aug-1999	nisimura	- 24bit per pixel TX framebuffer occupies 0x600000.
1.15	02-Aug-1999	nisimura	- Fix TX 8bpp framebuffer size, which occupies 2MB. - Rework CX RAMDAC register access like as other TC framebuffers.
1.14	30-Jul-1999	nisimura	- Fix TX 66Hz interrupt handling. Verified ok with PMAG-JA as an 8bpp console. XXX troubles in cursor color. - Typo in comments of MX.
1.13	25-Jun-1999	nisimura	- Show 1bpp for MX during configuration stage. - Replace memory layout 'struct' with array/pointer access.
1.12	07-May-1999	nisimura	- Sweep abit preparing for code merge to have common 'vdacops' across various graphics cards.
1.11	29-Mar-1999	nisimura	branches: 1.11.4; - Unnecessary to have '#include <machine/autoconf.h>' for those.
1.10	24-Mar-1999	mrg	completely remove Mach VM support. all that is left is the all the header files as UVM still uses (most of) these.
1.9	01-Mar-1999	nisimura	- Fix cursor image validity check error in set_cursor().
1.8	15-Jan-1999	thorpej	__pmax__ -> pmax, like other ports.
1.7	11-Jan-1999	drochner	remove dummy "load_font" entries
1.6	14-Dec-1998	nisimura	- Fix typos in commentary description.
1.5	19-Nov-1998	mrg	fix problems in many d_mmap routines: - returned EOPNOTSUPP rather than -1. - no check for negative offset. many of these fix potential security problems in these drivers. XXX XXX XXX the d_mmap cdev routine should be changed to have a prototype like: paddr_t (*d_mmap) __P((dev_t, off_t, int)); by someone!
1.4	18-Nov-1998	nisimura	- Fix cursor image handling bugs escaped in last commit.
1.3	09-Nov-1998	nisimura	- Fix many errors in cursor image manipulation. Hardware expect 2 bit/pixel format, not planer format. Assign MSB for cursor mask and LSB for cursor image, where 10 means mask color and 11 for image color. Image bit order of Bt431 and Bt459 are opposite to MIPS/Alpha processors while IMS G332 and DC503 (PCC) are indentical. - Assume that cursor images are 32 pixel padded as ULTRIX/DU ws interface do. It's natural to X server. - XXX Vast majority of codes are duplicated between mfb<->tfb and cfb<->sfb. Code sharing might be achieved in the context of TGA/SFB+ merge.
1.2	30-Oct-1998	nisimura	- Assign copyright terms.
1.1	29-Oct-1998	nisimura	- Introduce MI NWSCONS drivers for TURBOchannel framebuffer option cards. N.B., Digital UNIX never supports neither PMAG-AA (mfb) nor PMAG-BA (cfb) for TC Alphas. PMAG-DV (xcfb) is Personal DECstation built in. All should be good for console, but need much works for cursor/colormap completeness.

1.64.8.1	04-Aug-2021	thorpej	Adapt to CFARGS().
1.60	06-Dec-2021	abs	Add WSDISPLAYIO_GET_FBINFO support to most TURBOchannel framebuffers This adds WSDISPLAYIO_GET_FBINFO to cfb, mfb, sfb, tfb and xcfb TURBOchannel framebuffers as used by pmax and alpha It does not add support to px and pxg (they handle ioctls in common code in stic.c and more careful wiring is required) These changes allow an Xswfb X server to use the framebuffer directly, albeit without any special acceleration A subsequent change will re-enable X server building on pmax, and also hopefully switch alpha from Xorg 1.10 to 1.20
1.59	07-Aug-2021	thorpej	Merge thorpej-cfargs2.
1.58	24-Apr-2021	thorpej	branches: 1.58.8; Merge thorpej-cfargs branch: Simplify and make extensible the config_search() / config_found() / config_attach() interfaces: rather than having different variants for which arguments you want pass along, just have a single call that takes a variadic list of tag-value arguments. Adjust all call sites: - Simplify wherever possible; don't pass along arguments that aren't actually needed. - Don't be explicit about what interface attribute is attaching if the device only has one. (More simplification.) - Add a config_probe() function to be used in indirect configuiration situations, making is visibly easier to see when indirect config is in play, and allowing for future change in semantics. (As of now, this is just a wrapper around config_match(), but that is an implementation detail.) Remove unnecessary or redundant interface attributes where they're not needed. There are currently 5 "cfargs" defined: - CFARG_SUBMATCH (submatch function for direct config) - CFARG_SEARCH (search function for indirect config) - CFARG_IATTR (interface attribte) - CFARG_LOCATORS (locators array) - CFARG_DEVHANDLE (devhandle_t - wraps OFW, ACPI, etc. handles) ...and a sentinel value CFARG_EOL. Add some extra sanity checking to ensure that interface attributes aren't ambiguous. Use CFARG_DEVHANDLE in MI FDT, OFW, and ACPI code, and macppc and shark ports to associate those device handles with device_t instance. This will trickle trough to more places over time (need back-end for pre-OFW Sun OBP; any others?).
1.57	10-Nov-2019	chs	branches: 1.57.10; in many device attach paths, allocate memory with M_WAITOK instead of M_NOWAIT and remove code to handle failures that can no longer happen.

1.43	04-Mar-2007	christos	Kill caddr_t; there will be some MI fallout, but it will be fixed shortly.
1.42	12-Apr-2006	jmmv	branches: 1.42.14; Add an extra cookie to the ioctl and mmap wsdisplay accessops that points to the screen on which they are being called. The driver cannot guess this by itself but it is needed to implement, at least, the getwschar and putwschar functions in the correct place. There are no functional changes yet. Tested on i386 (vga, vga_raster, machfb, vesafb), macppc and sparc64. Suggested and reviewed by macallan@.
1.41	31-Mar-2006	thorpej	Use ANSI function decls, apply static.

1.36	20-Dec-2003	nisimura	- Minor coding modifications for VDAC register access. - De-__P() this time. Tested valid with 4MAXINE.
1.35	17-Dec-2003	ad	- Restore the display to a sane state when leaving mapped mode. - OR updates into sc_changed, and protect with spltty()/splx().
1.34	13-Dec-2003	ad	Make this compile again.
1.33	13-Nov-2003	chs	eliminate uvm_useracc() in favor of checking the return value of copyin() or copyout(). uvm_useracc() tells us whether the mapping permissions allow access to the desired part of an address space, and many callers assume that this is the same as knowing whether an attempt to access that part of the address space will succeed. however, access to user space can fail for reasons other than insufficient permission, most notably that paging in any non-resident data can fail due to i/o errors. most of the callers of uvm_useracc() make the above incorrect assumption. the rest are all misguided optimizations, which optimize for the case where an operation will fail. we'd rather optimize for operations succeeding, in which case we should just attempt the access and handle failures due to insufficient permissions the same way we handle i/o errors. since there appear to be no good uses of uvm_useracc(), we'll just remove it.
1.32	02-Oct-2002	thorpej	branches: 1.32.6; Add trailing ; to CFATTACH_DECL.
1.31	01-Oct-2002	thorpej	Use CFATTACH_DECL().
1.30	19-Aug-2002	itohy	Leaving overflow-sensitive code, very similar to what was fixed in the previous changes to cfb.c / sfb.c / xcfb.c, would not be clever. Just modify in the similar way.
1.29	06-Aug-2002	itojun	integer overflow. from silvio@qualys.com
1.28	04-Jul-2002	junyoung	alloc_attr -> allocattr Approved by Matthias Drochner.
1.27	17-Mar-2002	atatat	branches: 1.27.4; 1.27.6; Convert ioctl code to use EPASSTHROUGH instead of -1 or ENOTTY for indicating an unhandled "command". ERESTART is -1, which can lead to confusion. ERESTART has been moved to -3 and EPASSTHROUGH has been placed at -4. No ioctl code should now return -1 anywhere. The ioctl() system call is now properly restartable.
1.26	13-Mar-2002	ad	Reorganise the wsfont stuff slightly so that multiple display adapters with different bit/byte order requirements can co-exist happily.

1.21	27-Oct-2000	nisimura	branches: 1.21.2; Fix errors in initializing the software copy of 256 entry colormap stored in device softc. rasops_cmap[] array is orginazed in 256 iteration of 3 byte long RBG triplet, which does not match with struct wsdisplay_cmap design.
1.20	12-Sep-2000	nisimura	Found glyph pixel order inverted on screen.
1.19	28-Jun-2000	mrg	remove include of <vm/vm.h>. <vm/vm.h> -> <uvm/uvm_extern.h>
1.18	26-Jun-2000	simonb	Change the kernel mmap interface so that the offset to map is an "off_t" and the return value is a "paddr_t" to allow mappings at offsets past 2^31 bytes. Somewhat inspired by FreeBSD, which only changed the offset to a "vm_offset_t". Includes updates for the i386, pc532 and sh3 mmmmap from Jason Thorpe.
1.17	16-Mar-2000	nisimura	branches: 1.17.4; Place 34 by 80 console at the center of screen.
1.16	14-Mar-2000	nisimura	Respect video console colour designation by configration file.
1.15	14-Mar-2000	nisimura	Switch to improved flexible video console text rasterizer provided by rasops and wsfont.

1.11	07-May-1999	nisimura	branches: 1.11.2; 1.11.4; - Sweep abit preparing for code merge to have common 'vdacops' across various graphics cards.
1.10	30-Apr-1999	nisimura	- Nuke debugging aids mistakenly committed.
1.9	30-Apr-1999	nisimura	- I finally learned CSR_A register of IMS G332 VDAC must be treated as write only. Read-motify-write operation breaks its video mode. - VDAC regiters are now initialized as ULTRIX does.
1.8	29-Mar-1999	nisimura	branches: 1.8.4; - Unnecessary to have '#include <machine/autoconf.h>' for those.
1.7	24-Mar-1999	mrg	completely remove Mach VM support. all that is left is the all the header files as UVM still uses (most of) these.
1.6	11-Jan-1999	drochner	remove dummy "load_font" entries
1.5	19-Nov-1998	mrg	fix problems in many d_mmap routines: - returned EOPNOTSUPP rather than -1. - no check for negative offset. many of these fix potential security problems in these drivers. XXX XXX XXX the d_mmap cdev routine should be changed to have a prototype like: paddr_t (*d_mmap) __P((dev_t, off_t, int)); by someone!
1.4	19-Nov-1998	nisimura	- Fix an error in cursor color manipulation. 24bit RGB value was mistakenly assigned to unsigned short variable. - XXX PMAG-DV is supposed to emit virtical retrace interrupt, which can be used for colormap/cursor update just like other TURBOchannel framebuffers.
1.3	09-Nov-1998	nisimura	- Fix many errors in cursor image manipulation. Hardware expect 2 bit/pixel format, not planer format. Assign MSB for cursor mask and LSB for cursor image, where 10 means mask color and 11 for image color. Image bit order of Bt431 and Bt459 are opposite to MIPS/Alpha processors while IMS G332 and DC503 (PCC) are indentical. - Assume that cursor images are 32 pixel padded as ULTRIX/DU ws interface do. It's natural to X server. - XXX Vast majority of codes are duplicated between mfb<->tfb and cfb<->sfb. Code sharing might be achieved in the context of TGA/SFB+ merge.
1.2	30-Oct-1998	nisimura	- Assign copyright terms.
1.1	29-Oct-1998	nisimura	- Introduce MI NWSCONS drivers for TURBOchannel framebuffer option cards. N.B., Digital UNIX never supports neither PMAG-AA (mfb) nor PMAG-BA (cfb) for TC Alphas. PMAG-DV (xcfb) is Personal DECstation built in. All should be good for console, but need much works for cursor/colormap completeness.

1.43	07-Aug-2021	thorpej	Merge thorpej-cfargs2.
1.42	24-Apr-2021	thorpej	branches: 1.42.8; Merge thorpej-cfargs branch: Simplify and make extensible the config_search() / config_found() / config_attach() interfaces: rather than having different variants for which arguments you want pass along, just have a single call that takes a variadic list of tag-value arguments. Adjust all call sites: - Simplify wherever possible; don't pass along arguments that aren't actually needed. - Don't be explicit about what interface attribute is attaching if the device only has one. (More simplification.) - Add a config_probe() function to be used in indirect configuiration situations, making is visibly easier to see when indirect config is in play, and allowing for future change in semantics. (As of now, this is just a wrapper around config_match(), but that is an implementation detail.) Remove unnecessary or redundant interface attributes where they're not needed. There are currently 5 "cfargs" defined: - CFARG_SUBMATCH (submatch function for direct config) - CFARG_SEARCH (search function for indirect config) - CFARG_IATTR (interface attribte) - CFARG_LOCATORS (locators array) - CFARG_DEVHANDLE (devhandle_t - wraps OFW, ACPI, etc. handles) ...and a sentinel value CFARG_EOL. Add some extra sanity checking to ensure that interface attributes aren't ambiguous. Use CFARG_DEVHANDLE in MI FDT, OFW, and ACPI code, and macppc and shark ports to associate those device handles with device_t instance. This will trickle trough to more places over time (need back-end for pre-OFW Sun OBP; any others?).

1.23	13-Sep-2004	drochner	branches: 1.23.4; 1.23.6; a round of autoconf cleanup: -convert submatch() style functions (passed to config_search() or config_found_sm()) to the locator passing variants -pass interface attributes in some cases -make submatch() functions look uniformly as far as possible -avoid macros which just hide cfdata members, and reduce dependencies on "locators.h"
1.22	26-Aug-2004	drochner	kick out the ioasic offset check which happens in submatch() now
1.21	06-Mar-2003	matt	branches: 1.21.2; Add cn_halt and cn_flush entries to consdevs. (needed for dma-only console devices).

1.16	27-Sep-2002	thorpej	Introduce a new routine, config_match(), which invokes the cfattach->ca_match function in behalf of the caller. Use it rather than invoking cfattach->ca_match directly.
1.15	27-Sep-2002	thorpej	Rather than referencing the cfdriver directly in the cfdata entries, instead use a string naming the driver. The cfdriver is then looked up in a list which is built at run-time.
1.14	26-Sep-2002	thorpej	G/c extern reference to ioasic_cd.
1.13	26-Sep-2002	thorpej	No need to make sure parent's cfdriver == &ioasic_cd.
1.12	24-Sep-2002	ad	Deal with the strange SCC wiring on TC IOASIC machines. Thanks to Bill Studenmund and Jonathan Stone for useful comments.
1.11	06-Sep-2002	gehenna	Merge the gehenna-devsw branch into the trunk. This merge changes the device switch tables from static array to dynamically generated by config(8). - All device switches is defined as a constant structure in device drivers. - The new grammer ``device-major'' is introduced to ``files''. device-major <prefix> char <num> [block <num>] [<rules>] - All device major numbers must be listed up in port dependent majors.<arch> by using this grammer. - Added the new naming convention. The name of the device switch must be <prefix>_[bc]devsw for auto-generation of device switch tables. - The backward compatibility of loading block/character device switch by LKM framework is broken. This is necessary to convert from block/character device major to device name in runtime and vice versa. - The restriction to assign device major by LKM is completely removed. We don't need to reserve LKM entries for dynamic loading of device switch. - In compile time, device major numbers list is packed into the kernel and the LKM framework will refer it to assign device major number dynamically.

Still a little to do before useful for DECstation. MI softintr required. - allow wildcard matchs to have zstty/zskbd/zsms in default hardware configuration. - abandon to check zs_ioasic_cnattach() return value; it doesn't fail. - have zs_ioasic_cnattach() serial line parameters hardcoded inside, in symmetry with zs_ioasic_lk201_cnattach().
1.3	09-Sep-2000	nisimura	u_char -> u_int for function argument and return of Zilog register manipulation helper functions; no loss, no gain, for Alpha processor.
1.2	05-Jul-2000	nisimura	- Withdraw ZS_IOASIC_DMA conditional which has never been useful. - Sanitize ZS register access.
1.1	05-Jul-2000	nisimura	Repopulate 4 files, zs_ioasic.c and zs_ioasicvar.h from arch/alpha/tc, zskbd.c and zsms.c from dev/dec/, respectively. No functionality change this time.

1.20	07-Aug-2021	thorpej	Merge thorpej-cfargs2.
1.19	24-Apr-2021	thorpej	branches: 1.19.8; Merge thorpej-cfargs branch: Simplify and make extensible the config_search() / config_found() / config_attach() interfaces: rather than having different variants for which arguments you want pass along, just have a single call that takes a variadic list of tag-value arguments. Adjust all call sites: - Simplify wherever possible; don't pass along arguments that aren't actually needed. - Don't be explicit about what interface attribute is attaching if the device only has one. (More simplification.) - Add a config_probe() function to be used in indirect configuiration situations, making is visibly easier to see when indirect config is in play, and allowing for future change in semantics. (As of now, this is just a wrapper around config_match(), but that is an implementation detail.) Remove unnecessary or redundant interface attributes where they're not needed. There are currently 5 "cfargs" defined: - CFARG_SUBMATCH (submatch function for direct config) - CFARG_SEARCH (search function for indirect config) - CFARG_IATTR (interface attribte) - CFARG_LOCATORS (locators array) - CFARG_DEVHANDLE (devhandle_t - wraps OFW, ACPI, etc. handles) ...and a sentinel value CFARG_EOL. Add some extra sanity checking to ensure that interface attributes aren't ambiguous. Use CFARG_DEVHANDLE in MI FDT, OFW, and ACPI code, and macppc and shark ports to associate those device handles with device_t instance. This will trickle trough to more places over time (need back-end for pre-OFW Sun OBP; any others?).
