1.27	03-May-2022	andvar	fix various typos, mainly s/trasfering/transferring/ and s/theese/these/.
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dead code: cobalt ews4800mips hp300 hppa ia64 luna68k vax acorn32/if_ie.c (not included in any kernels) macppc/if_gm.c (superseded by gem(4)) It should be easy to fix the fallout once identified -- this way of doing things fails safe, and the goal here, after all, is to _avoid_ silent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!)
1.25	13-Oct-2012	tsutsui	branches: 1.25.36; 1.25.38; Fix botch on device_t/softc split in debug printf macro. from chs@
1.24	09-Jul-2011	matt	branches: 1.24.2; 1.24.12; Cleanu <machine/*> includes
1.23	14-Dec-2009	matt	Merge from matt-nb5-mips64 Merge mips-specific arch files.
1.22	12-Aug-2009	tsutsui	Fix a botch in the previous rev 1.21: We have to mask higher bits on NCR register access via bus_space_read_4(9), as the previous NCR_READ_REG() does. Problem reported by Erik Bertelsen on port-pmax@. I tested a different version on 3MIN and I also tested committed version on gxemul, but 3MAX doesn't have asc_ioasic but asc_tc..
1.21	01-Aug-2009	tsutsui	Micro optimization around ncr53c9x register accesses.
1.20	28-Apr-2008	martin	branches: 1.20.18; Remove clause 3 and 4 from TNF licenses
1.19	13-Apr-2008	tsutsui	branches: 1.19.2; 1.19.4; Split device_t/softc for MI ncr53c9x and some related devices, with various cleanup.
1.18	06-Mar-2007	simonb	branches: 1.18.40; Fix some caddr_t rototill fallout. Some from Erik Bertelsen on port-pmax@.
1.17	04-Mar-2007	christos	Kill caddr_t; there will be some MI fallout, but it will be fixed shortly.
1.16	08-Mar-2006	lukem	branches: 1.16.16; Use the SI capitalization for "Hz", "kHz", and "MHz" in comments and strings. Add a space between numbers and Hz unit.
1.15	02-Apr-2003	thorpej	branches: 1.15.18; 1.15.32; 1.15.34; 1.15.36; 1.15.38; Use PAGE_SIZE rather than NBPG.
1.14	02-Oct-2002	thorpej	Use CFATTACH_DECL().
1.13	27-Sep-2002	thorpej	Declare all cfattach structures const.
1.12	26-Aug-2001	simonb	branches: 1.12.6; Switch to MI SCSI and drop old pmax MD SCSI support completely.
1.11	25-Apr-2001	bouyer	branches: 1.11.2; 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
1.10	28-Sep-2000	mhitch	branches: 1.10.2; Set the boundary to NBPG for bus_dmamap_create(). The IOASIC DMA segment can not cross a page boundary. This fixes a problem when a dump(8) buffer just crossed a page boundary and bus_dmamap_load() would coalesce the the overlap onto the first segment. The NEXTPTR value would get set to -1 when starting the DMA transfer and the residual data for unaligned transfers would be copied to physical address 0x1ffffffc. On the R3000, this would result in corrupted data, and on the R4000 would usually result in a hard system hang.
1.9	07-Jun-2000	nisimura	branches: 1.9.2; - Take care of dm_segs[].dm_len value whenever the offset is adjusted. Known not working well for 4MAX+ this moment. - White spacing.
1.8	05-Jun-2000	nisimura	Have MI ncr53c9x_attach() the 2nd and 3rd arguments for scsipi_adater and scsipi_device respectively, with size reduction of ncr53c9x_softc. Specifying NULL instructs the driver to use default adapter and default device codes. Every target port has ncr53c9x_attach(sc, NULL, NULL) anyway.
1.7	03-Jun-2000	nisimura	Use bus_dma(9) to instruct IOASIC DMA to load transferring addresses, eliminating MIPS cache machinary exposure here.
1.6	06-Mar-2000	mhitch	branches: 1.6.2; Get rid of hook for dk_establish() - pmax will now use device_register().
1.5	04-Mar-2000	nisimura	Cosmetic cleanups to hide local objects.
1.4	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. Also change the rz boot device test to include a check for the adapter so that it works when booting from a disk on adapters other than the first one.
1.3	28-Feb-2000	mhitch	Check and clear the appropriate IOASIC SCSI interrupt bits when in polled I/O mode. Kernel dumps will now work with the IOASIC SCSI devices.
1.2	19-Feb-2000	nisimura	Introduce MI SCSI codes; for DECstation 5000s only this moment.
1.1	15-Oct-1998	nisimura	branches: 1.1.2; 1.1.4; file asc_ioasic.c was initially added on branch nisimura-pmax-wscons.
1.1.4.2	29-Mar-2001	bouyer	Pass compile-test on i386
1.1.4.1	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.
1.1.2.15	14-Mar-2000	nisimura	Synchronize with the recent improvements of main trunk. Main trunk filled gaps toward this, indeed.
1.1.2.14	19-Nov-1999	nisimura	Merge w/ recent changes in main trunk.
1.1.2.13	10-Sep-1999	nisimura	Fix an error in DMAPTR adjustment in unaligned transaction.
1.1.2.12	09-Sep-1999	nisimura	Add more SCR/SDR0/SDR1 improvement. From the analysis on Mach3/pmax codes. IOASIC SCSI DMA is performed on 8-byte boundary. Unaligned transaction requires special care managed by these registers. SDR0/SDR1 hold unaligned data upto 6 bytes in 2 byte increment while SCR indicates the cases. Disk block I/O operation behaves gracefully and is immune to unaligned transfers. TODO.1 - introduce bus_dmamap_load(); must be good for either of R3000 cache and R4000 cache. TODO.2 - handle PTR LOAD interrupt to perform 'chained' DMA spans 3+ page long. TODO.3 - tape drive ... TODO.4 - syncing disks on halt/reboot. TODO.5 - dumping core memory on panic. TODO.6 - test ss/uk/ch drives.
1.1.2.11	06-Sep-1999	nisimura	Fix missing shift adjustment of DMAPTR value. Still no luck for tape drive.
1.1.2.10	05-Sep-1999	nisimura	- Add SCR/SDR0/SDR1 register handling supposedly necessary (but failed to cure any of erroneous behavoiurs I'm experiencing ...)
1.1.2.9	06-Apr-1999	nisimura	- Another bit improvement toward bus_space(9).
1.1.2.8	05-Apr-1999	nisimura	- A bit improvement toward bus_space(9).
1.1.2.7	30-Mar-1999	nisimura	- Restore a local variable mistakenly omitted. - sc_iswrite -> sc_ispullup (pull up from SCSI device).

1.9.2.1	30-Sep-2000	mhitch	Pull up rev 1.10 [approved by thorpej]. Set the boundary to NBPG for bus_dmamap_create(). The IOASIC DMA segment can not cross a page boundary. This fixes a problem when a dump(8) buffer just crossed a page boundary and bus_dmamap_load() would coalesce the the overlap onto the first segment.

1.38	09-Sep-1999	nisimura	Remove now defunct local implementation of ioasic_lance_dma_setup().
1.37	03-Sep-1999	nisimura	- Nuke '#ifdef alpha' which brings little useful, plus a small cleanup.
1.36	26-Apr-1999	nisimura	- Forgot to commit these two.
1.35	24-Apr-1999	simonb	Nuke register and remove trailling white space.
1.34	18-Mar-1999	simonb	branches: 1.34.4; Don't prototype ioasicprint() - the prototype is now in dev/tc/ioasicvar.h and we don't use it here anyway.
1.33	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.
1.32	14-Mar-1999	jonathan	Clean up initializers for pmax ioasic children. Use same struct as alpha.
1.31	12-Mar-1999	nisimura	- Nuke old leftover; round two. XXX Still there 3MAX's IOASIC disguise. Rework will be done in conf/files.pmax, anyway.
1.30	05-Sep-1998	nisimura	branches: 1.30.2; - Clearify what ioasic_init() is for. No runtime difference because NetBSD/pmax does not fully utilize the hardware features.
1.29	21-May-1998	thorpej	Make this build for a 3MAX-only kernel.
1.28	25-Apr-1998	jonathan	Resync 3max (kn02) support.
1.27	19-Apr-1998	jonathan	Rework, based loosely on suggestions from Tohru Nisimura..
1.26	26-Mar-1998	thorpej	It's Just Wrong to configure a KN02 system slot as an IOCTL ASIC, but since it's currently done that way, nuke the gratuitous printf that reports the behavior.
1.25	25-Mar-1998	jonathan	* Use new defopt model-specific options and opt files. Replace all DS5000_* and DS3100 ifdefs with ifdefs on DEC_ options. * Use MI declarations, not pmax-specific, in model-specific init that uses baseboard (ioasic) registers. * Further cleanup of machdep.c. Clock-tick still needs more thought. * Use 'ibus' names for 3100 baseboard devices in MI code.
1.24	25-Mar-1998	jonathan	Split sys/arch/pmaxpmax/{machdep.c,trap.c} as suggested by Jason Thorpe: * add "Platform" support inpmax/pmax/sysconf.c and pmax/include/sysconf.h (based on Alpha cpuconf.[ch], with a namechange to avoid clashes with support for models of MIPS cpus. They differ more than Alphas). * For each supported model of DECstation, create a separate file with the support for that model. Use model codenames, since support is really baseboard-specific and CPU daugherboards can change. Move code from machdep.c and pmax_trap.c, Add sysconf (nee "cpuconf") support. * Rename model-specific functions to match sysconf names. * Clean up autoconf.c. Use platform callbacks. * Retire pmax_trap.c. Leaves I/O bus configuration and console configuration untouched.
1.23	12-Jan-1998	thorpej	Update for changes to config.
1.22	21-Jul-1997	jonathan	Kill __BROKEN_INDIRECT_CONFIG on pmax. Based on a patch from Chris G. Demetriou, December 1996.
1.21	17-Jul-1997	jtk	use locator defines in "locators.h" to index cf_loc[]
1.20	16-Jun-1997	jonathan	Garbage-collect '#include <machine/pte.h>'.
1.19	16-Jun-1997	jonathan	<machine/locore.h> -> <machine/bus.h>
1.18	16-Jun-1997	jonathan	Remove the machConst.h (wrapper for Sprite-derived source), and all #includes <machine/machConst.h> uses. Other header files now include <mips/cpuregs.h> where necessary.
1.17	15-Jun-1997	mhitch	DECstation MIPS3 support: wbflush() is cpu-dependent, need declaration from machine/locore.h.
1.16	24-May-1997	jonathan	Delint debugging-printf() macro.
1.15	13-Oct-1996	christos	backout previous kprintf change
1.14	11-Oct-1996	christos	printf -> kprintf, sprintf -> ksprintf
1.13	06-Oct-1996	jonathan	Update pmax drivers to use "const" on 2nd arg to cfprint_t: turbocnhannel: include/tc_machdep.h, tc/tc_subr.c, tc/asic.c kn01 baseboard: pmax/mainbus.c
1.12	09-Sep-1996	jonathan	Apply diff from the 1.2 release branch, so that ugly IOASIC debugging is disabled by default: >revision 1.9.4.2 >date: 1996/09/09 20:19:11; author: thorpej; state: Exp; lines: +2 -18 >Disable IOASIC_DEBUG so that autoconfiguration looks normal, by request >of Jonathan Stone
1.11	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).
1.10	29-May-1996	mhitch	Fix autoconfiguration stuff to more closely match the alpha - primarily the IOASIC attached devices. The DS3100 will now configure properly. Fix the DS5000/25 IOASIC table entry for the RTC so the RTC interrupts get enabled. Fix up a moved include file.
1.9	17-Mar-1996	thorpej	branches: 1.9.4; 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.
1.8	31-Jan-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'.
1.7	29-Jan-1996	jonathan	Re-write Decstation turbochannel autoconfiguration code to use the machine- independent TC support in sys/dev/tc/tc.c and sys/dev/tc/tcvar.h: * Change the tc autoconfiguration tables to use a struct tc_attach_args instead of the ad-hoc structure. * Change all pmax device drivers to use a `struct confargs' that's assignment-compatible with sys/dev/tc/tcvar.h `struct tcdev_attach_args'. Devices that can be present on a TC or as ioctl asic/mainbus builtins use the same `struct confargs'. * Eliminate the `BUS_CVTADDR()' macros which the pmax port inherited from an old, now-obsolete sys/arch/alpha snapshot. * Update the comments and debugging code in interrupt handlers to be consistent with the machine-independent TC support. Other commits that overlap the same source files include: re-enabling clock-tick interrupts earlier, and counting hardclock ticks for vmstat -i.
1.6	25-Sep-1995	jonathan	Update pmax kernel to compile with -Werror: Update TURBOChannel and ioasic interrupt-establish routines to pass on their device argument as a "void *", since that's how all the pmax interrupt handlers are declared.
1.5	12-Sep-1995	jonathan	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.)
1.4	29-Aug-1995	jonathan	Fix references to ASIC_SLOT_RTC, which isn't yet defined on DECstations.
1.3	18-Aug-1995	jonathan	Initialize the ioasic slot probe table for the 3MIN (Decstation 5k/1xx) and MAXINE (Decstation 5k/xx), instead of setting them to NULL. New-config kernels should work on those machines now. Rename the definition of the struct cfdriver for the IO ASIC from "asiccd" to "ioasiccd", as the config-file name changed from "asic" to "ioasic".
1.2	10-Aug-1995	jonathan	Move IO ASIC interrupt-enable outside #ifdef DEBUG, where it had accidentally snuck in. Clean up debugging messages and explicitly give a warning on CPUs the code hasn't been tested on.
1.1	07-Aug-1995	jonathan	New-style config (config.new) autoconfiguration code for Decstation turhsturbochannel machines. Lifted wholesale from cgd's Alpha turbochannel code, with changes that reflect the slightly different bus topology and `slot' numbering on Decstations.
1.9.4.2	09-Sep-1996	thorpej	Disable IOASIC_DEBUG so that autoconfiguration looks normal, by request from Jonathan Stone.

1.7	19-Apr-1998	jonathan	Rework pmax turbochannel config, as suggested by Jason Thorpe. Also make TC framebuffer-console search table-driven. Does not yet include "tcasic" layer; there's no such hardware on DECstations and nothing for a tcasic layer to do.
1.6	29-May-1996	mhitch	Fix autoconfiguration stuff to more closely match the alpha - primarily the IOASIC attached devices. The DS3100 will now configure properly. Fix the DS5000/25 IOASIC table entry for the RTC so the RTC interrupts get enabled. Fix up a moved include file.

1.4	03-Jan-1996	jonathan	arch/pmax/tc -> dev/tc, pass 1: Eliminate pmax/tc/tc.h. Use dev/tc headers for pmax port. Change pmax TC autoconfig tables to use structs (mostly) compatible with dev/tc/tcvar.h. Move TC console search to tc.c.
1.3	09-Oct-1995	jonathan	Fix bugs in the turbochannel config table for MAXINE (personal decstation).
1.2	09-Aug-1995	jonathan	Add missing "priority" field value in KN02 "asic" configuration entry for the Dallas-compatible real-time clock. The missing entry caused the offset to end up in the "priority" field. New-style config now boots cleanly on a KN02 (3MAX).
1.1	07-Aug-1995	jonathan	New-style config (config.new) autoconfiguration code for Decstation turhsturbochannel machines. Lifted wholesale from cgd's Alpha turbochannel code, with changes that reflect the slightly different bus topology and `slot' numbering on Decstations.
1.5.4.1	30-May-1996	mhitch	Pulled autoconfig fixes up from the trunk
1.8	27-Feb-1996	jonathan	Replace tc.c and ds-tc-conf.c with a re-written tc_subr.c. tc_subr.c works with the revamped machine-independent TC code in sys/dev/tc. A name change is necessary to avoid a name clash with sys/dev/tc/tc.c, which also creates a tc.o.
1.7	29-Jan-1996	jonathan	Re-write Decstation turbochannel autoconfiguration code to use the machine- independent TC support in sys/dev/tc/tc.c and sys/dev/tc/tcvar.h: * Change the tc autoconfiguration tables to use a struct tc_attach_args instead of the ad-hoc structure. * Change all pmax device drivers to use a `struct confargs' that's assignment-compatible with sys/dev/tc/tcvar.h `struct tcdev_attach_args'.

1.16	07-Aug-2021	thorpej	Merge thorpej-cfargs2.
1.15	24-Apr-2021	thorpej	branches: 1.15.8; 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?).

1.9	17-Oct-2007	garbled	branches: 1.9.16; 1.9.18; 1.9.20; Merge the ppcoea-renovation branch to HEAD. This branch was a major cleanup and rototill of many of the various OEA cpu based PPC ports that focused on sharing as much code as possible between the various ports to eliminate near-identical copies of files in every tree. Additionally there is a new PIC system that unifies the interface to interrupt code for all different OEA ppc arches. The work for this branch was done by a variety of people, too long to list here. TODO: bebox still needs work to complete the transition to -renovation. ofppc still needs a bunch of work, which I will be looking at. ev64260 still needs to be renovated amigappc was not attempted. NOTES: pmppc was removed as an arch, and moved to a evbppc target.

1.4	15-Jan-2005	mhitch	Detection of mouse packet did not work with my mouse. It only sends 6 bytes instead of the 8 defined by struct dt_locator_msg. Change the dectection so we swap the mouse/keyboard addresses only if the packets don't match what's expected (rather than on every packet). My mouse now works, and if a different mouse sends an 8 byte packet, it should also work.
1.3	23-Dec-2003	ad	MAXINE keyboard and mouse now works, albeit with some minor issues.

1.5	10-Jan-2005	mhitch	branches: 1.5.10; Fix Maxine keyboard and mouse ioctl routines to return EPASSTHROUGH for unrecognized commands so they can be passed to other handlers.
1.4	10-Jan-2005	mhitch	Maxine mouse buttons were being mapped incorrectly (old dtop.c code mapped them to serial mouse buttons, which were then mapped into events to pass to the X server). Also fix bug in mouse motion - putting 2 unsigned bytes into an integer resulted in a 16-bit unsigned value, so negative mouse motion didn't work.
1.3	23-Dec-2003	ad	MAXINE keyboard and mouse now works, albeit with some minor issues.

1.11.68.1	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.
1.12.8.1	04-Aug-2021	thorpej	Adapt to CFARGS().

1.1.2.5	11-May-1999	nisimura	- Catch up to recent main trunk changes. - Make target platform files to have TURBOchannel slot definitions and nuke tc_machdep.c. - MIPS processor needs not to have tc_mb() before ZS register read ops.

1.1.2.3	23-Oct-1998	nisimura	- Fix typos.
1.1.2.2	23-Oct-1998	nisimura	- An inch progress of dtop.c towards NWSCONS. Still useless. As ACCESS.bus (Digital called this in many ways) runs much faster than 4800bps serial interconnect, smart "packet disassembler" might be required with the help of DMA circuit. Packet interpretation of LK501 -> LK201 might be also a pain...
1.1.2.1	15-Oct-1998	nisimura	- new asc driver combined with MI NCR53C9x and MI SCSI. - import zs_ioasic.? from NetBSD/alpha. - NWSCONS drivers for various DECstations. - squash tc_xxx.c into single tc_machdep.c

1.16	13-Oct-1996	jonathan	Remove pmax/tc/if_le.c. Superseded by sys/dev/tc MI TC/ioasic lance drivers.
1.15	13-Oct-1996	christos	backout previous kprintf change
1.14	11-Oct-1996	christos	printf -> kprintf, sprintf -> ksprintf
1.13	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_start)() to take a struct ifnet *, rather than a unit number.
1.12	22-Apr-1996	christos	Add a hardware dependent initialization function lehwinit()
1.11	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).
1.10	18-Mar-1996	jonathan	Additional fixes to complete the NetBSD/1.1B config changes: Add new device-attach struct cfattach le_tc_ca and struct cfdriver le_cd. Change IOASIC cfdriver references from "ioasiccd" to "ioasic_cd". Change "mainbuscd" to "mainbus_cd"
1.9	31-Jan-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'.
1.8	29-Jan-1996	jonathan	Re-write Decstation turbochannel autoconfiguration code to use the machine- independent TC support in sys/dev/tc/tc.c and sys/dev/tc/tcvar.h: * Change the tc autoconfiguration tables to use a struct tc_attach_args instead of the ad-hoc structure. * Change all pmax device drivers to use a `struct confargs' that's assignment-compatible with sys/dev/tc/tcvar.h `struct tcdev_attach_args'. Devices that can be present on a TC or as ioctl asic/mainbus builtins use the same `struct confargs'. * Eliminate the `BUS_CVTADDR()' macros which the pmax port inherited from an old, now-obsolete sys/arch/alpha snapshot. * Update the comments and debugging code in interrupt handlers to be consistent with the machine-independent TC support. Other commits that overlap the same source files include: re-enabling clock-tick interrupts earlier, and counting hardclock ticks for vmstat -i.
1.7	28-Dec-1995	jonathan	Use machine-independent TurboChannel include files from dev/tc. Add machine-dependent TC definitions in pmax/include/tc_machdep.h.
1.6	28-Dec-1995	jonathan	* empty log message *
1.5	22-Dec-1995	jonathan	Re-apply fix from before the NetBSD/1.1 version: actually write the pointer to the LANCE's dma region into the IO ASIC after computing it.
1.4	17-Dec-1995	jonathan	Remove LENITR_UNIT and supporting code that allowed passing a unit number, instead of a softc pointer, to leintr(). Pmaxes don't need it anymore.
1.3	25-Nov-1995	cgd	allow bus-specific lance drivers to use machine-independent buffer/descriptor copy functions, and convert isa and pmax drivers to do so.
1.2	17-Aug-1995	jonathan	branches: 1.2.2; Merge back fixes from the merged Decstation/Alpha driver. Remove all references to #ifdef SPARSE, and use #ifdef alpha instead. Only initialize ASIC dma on a machine with an ASIC.
1.1	11-Aug-1995	jonathan	Re-port the Alpha versino of NetBSD's machine-independent LANCE driver back to the DECstation. Boots on 3MAX and 3MAXPLUS. The bug-fixes applied to this driver since it forked off the Decstation code also seem to fix long-standing DMA problems with the Decstation SCSI driver.
1.2.2.1	13-Oct-1995	jonathan	Commit a version of the pmax lance driver that's been cleaned up to compile with -Werror to the NetBSD-1.1 tree.
1.4	13-Oct-1996	jonathan	Remove pmax/tc/if_le.c. Superseded by sys/dev/tc MI TC/ioasic lance drivers.
1.3	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.

1.1	15-Oct-1998	nisimura	branches: 1.1.2; file ims332reg.h was initially added on branch nisimura-pmax-wscons.
1.1.2.2	30-Oct-1998	nisimura	- Migrate to MI TURBOchannel codes.
1.1.2.1	15-Oct-1998	nisimura	- new asc driver combined with MI NCR53C9x and MI SCSI. - import zs_ioasic.? from NetBSD/alpha. - NWSCONS drivers for various DECstations. - squash tc_xxx.c into single tc_machdep.c
1.23	03-Sep-2020	simonb	The TC device addresses are defined in KSEG1, but this confuses bus_space(9) which expects bus addresses and not kernel virtual addresses. Pull the addresses back to bus addresses with MIPS_KSEG1_TO_PHYS(). XXX: Fix this properly one day (without storing KSEG1 addrs in the TC device configuration). Fixes problem with TURBOchannel pmaxes panicing during autoconfiguartion.
1.22	10-Nov-2013	christos	fix unused variable warnings
1.21	09-Jul-2011	matt	branches: 1.21.2; 1.21.12; 1.21.16; Cleanu <machine/*> includes
1.20	04-Jun-2011	tsutsui	Split device_t/softc. pmax is tested on GXemul, compile test only for alpha.
1.19	16-Mar-2009	dsl	branches: 1.19.4; 1.19.6; 1.19.10; ANSIfy functions with function-pointer arguments
1.18	14-Mar-2009	dsl	ANSIfy another 1261 function definitions. The only ones left in sys are beyond by sed script! (or in sys/dist or sys/external) Mostly they have function pointer parameters.
1.17	14-Mar-2009	dsl	Change about 4500 of the K&R function definitions to ANSI ones. There are still about 1600 left, but they have ',' or /* ... */ in the actual variable definitions - which my awk script doesn't handle. There are also many that need () -> (void). (The script does handle misordered arguments.)
1.16	14-Mar-2009	dsl	Remove all the __P() from sys (excluding sys/dist) Diff checked with grep and MK1 eyeball. i386 and amd64 GENERIC and sys still build.
1.15	02-Oct-2002	thorpej	branches: 1.15.112; 1.15.120; 1.15.126; Use CFATTACH_DECL().
1.14	11-Jul-2000	nisimura	branches: 1.14.4; 1.14.8; - Use PMAD-BA name for device match logic. It's not a real TURBOchannel device and the id string is not found in option ROM string, but ULTRIX/OSF1 call it so anyway. - Squash IOASIC DMA buffer allocation into device attach() sequence.
1.13	04-Jun-2000	cgd	Implement the more flexiable `evcnt' interface as discussed (briefly) on tech-kern and now documented in evcnt(9).
1.12	15-Mar-2000	nisimura	branches: 1.12.2; Eliminate unused sc_cookie field of struct ioasic_softc.
1.11	29-Feb-2000	nisimura	- Have SYS_DEV_xxx device cookie symbols to select and install proper interrupt handlers into intrtab[] array, rather than the idea of devices in 'psuedo' TURBOchannel slots. - Nuke symbols for psuedo TC slots. - Abandon never/unlikely used intr_disestablish()s.
1.10	03-Feb-2000	nisimura	Merge IOASIC register definitions.
1.9	03-Feb-2000	nisimura	Not to use (cfdata->cf_unit > 0) conditional in device match() routine.
1.8	14-Jan-2000	simonb	Redo interrupt establishment, based in part on work on the [nisimura-pmax-wscons] branch and suggestions from Toru Nisimura: - Remove bogus tc_slot_info[] name for interrupt handling array and replace with simplified struct intrhand intrtab[] array. - Add intr_establish() and intr_disestablish() function pointers to struct platform and initialise this in each model-specific initialisation, and remove global tc_enable_interrupt function pointer. - Remove model-specific function declarations from ibus/ibusvar.h. This is functionally identical to the current scheme, and doesn't yet try to commonise interrupt establishment by bus type as the [nisimura-pmax-wscons] branch does. Also, move cpuspeed variable from autoconf.c to machdep.c
1.7	10-Jan-2000	simonb	Remove unneeded include files (up to 16 in two files!).
1.6	10-Jan-2000	simonb	Add trailing quote to RCS ID.
1.5	09-Jan-2000	ad	RCS ID police.
1.4	08-Jan-2000	simonb	Function prototype cleanup.
1.3	06-Dec-1999	simonb	branches: 1.3.2; Fix typo in 3max+ scc1 device declaration - console output on a serial console 3max+ works again.
1.2	01-Dec-1999	nisimura	Replace old asic.c with one imported from a development branch.
1.1	15-Oct-1998	nisimura	branches: 1.1.2; 1.1.4; file ioasic.c was initially added on branch nisimura-pmax-wscons.
1.1.4.1	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.

1.20	14-Mar-2009	dsl	Remove all the __P() from sys (excluding sys/dist) Diff checked with grep and MK1 eyeball. i386 and amd64 GENERIC and sys still build.
1.19	03-Jan-2008	joerg	branches: 1.19.10; 1.19.18; 1.19.24; Timecounter and generic todr support for pmax. From Garret D'Amore.

1.12	09-Jan-2000	simonb	Use the badaddr() prototype in mips/include/cpu.h by including <machine/cpu.h> in mips/include/mips_param.h. Remove duplicate badaddr() prototypes from some pmax header files.
1.11	09-Jan-2000	simonb	The clean-up continues: - Make local-only function and variables static. - Move function prototypes and extern variable declarations to header files. - Delete unused variables. There's still a handful of extern declaraions that should be fixed up.
1.10	08-Jan-2000	simonb	Function prototype cleanup.
1.9	15-Nov-1999	nisimura	Very large scale change to sweep obstracles to remove 3MAX IOASIC disguise. - Rework ibus device configuration and interrupt handler assignment. - Remove TC device exposure in 'mainbus.c' - Squash 'ibus_{3100,5100}.c' into a file; it can not cope with 3max. - 'struct confargs' -> 'struct mainbus_attach_args' Now about to remove tc_slot_info[] and tc_enable_interrupt inherited from 4.4BSD.
1.8	24-Apr-1999	simonb	branches: 1.8.2; 1.8.8; Nuke register and remove trailling white space.
1.7	19-Apr-1998	jonathan	branches: 1.7.4; 1.7.12; oops, diffs to use dev/dec/mcclock_pad32 were in a different tree. Fix.
1.6	19-Apr-1998	jonathan	Copy alpha/tc/mcclock_ioasic.c (duplicated in pmax/tc/mcclock_ioasic.c) into sys/dev/dec and split into a clockfns layer and a "middle" layer for other DEC systems which use mcclocks with each onchip byte register padded out to a 32-bit word. Clone alpha/alpha/mcclock (also duplicated in pmax port) into sys/dev/dec, and ifdef for default clockrates on pmax and alpha. Use new machinery on pmax for ibus,ioasic attached mcclocks.
1.5	01-Feb-1998	jonathan	Use correct name ("ioasic") when checking parent bus.
1.4	06-Aug-1997	jonathan	branches: 1.4.4; Garbage-collect Mach_clock_addr outside of machdep.c. Use as mcclock_addr inside machdep.c, to disable clock interrupts until the clock is autoconfigured.
1.3	22-Jul-1997	jonathan	branches: 1.3.2; Move sys/dev/tc/mcclockvar.h -> sys/dev/dec/mcclockvar.h. Update pmax clock code.
1.2	22-Jul-1997	jonathan	Include /sys/dev/dec/clockvar.h. Garbage-collect tc/clockvar.h.
1.1	22-Jun-1997	jonathan	Import mcclock from NetBSD/Alpha, mostly replacing the Sprite clock code. interface. From Toru Nishimura <nisimura@itc.aist-nara.ac.jp>. Partly merged back with Alpha code by Jonathan Stone. Needs more merging.

1.89	14-Dec-2005	oster	branches: 1.89.4; 1.89.6; 1.89.8; 1.89.10; more proc->lwp changes. (untested, but at least the pmax kernel builds)
1.88	11-Dec-2005	christos	merge ktrace-lwp.
1.87	06-Sep-2005	kleink	Change the driver open function's conditional for overriding exclusive tty use from checking the proc's uid to suser(9), and account for the use of privileges. Noted by David Holland in PR kern/31126. Also change this to use the proc argument instead of curproc.
1.86	01-Jun-2005	drochner	branches: 1.86.2; quell cast-qual and shadow warnings

1.77	06-Jan-2003	wiz	through, not throught.
1.76	23-Oct-2002	jdolecek	merge kqueue branch into -current kqueue provides a stateful and efficient event notification framework currently supported events include socket, file, directory, fifo, pipe, tty and device changes, and monitoring of processes and signals kqueue is supported by all writable filesystems in NetBSD tree (with exception of Coda) and all device drivers supporting poll(2) based on work done by Jonathan Lemon for FreeBSD initial NetBSD port done by Luke Mewburn and Jason Thorpe
1.75	02-Oct-2002	thorpej	Use CFATTACH_DECL().
1.74	27-Sep-2002	thorpej	Declare all cfattach structures const.
1.73	26-Sep-2002	thorpej	No need to check that parent's cfdriver is ioasic_cd.
1.72	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.
1.71	17-Mar-2002	atatat	branches: 1.71.4; 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.
1.70	07-Jul-2001	simonb	branches: 1.70.2; 1.70.4; 1.70.8; b{cmp,copy,zero} -> mem{cmp,cpy,set} Also remove some unnecessary argument casts.
1.69	02-May-2001	scw	Add `l_poll' to `struct linesw' and provide an xxxpoll() entry point in each tty driver to indirect through it. This allows tty line-disciplines to handle poll(2) system calls.
1.68	31-Mar-2001	enami	Remove unnecessary test of tp->t_linesw against NULL; they are results of confusion while correcting compilation error after t_line is replaced with t_linesw.
1.67	03-Nov-2000	simonb	branches: 1.67.2; Fix up line discipline change fallout.
1.66	02-Nov-2000	eeh	Adapt to new line discipline scheme.
1.65	06-Mar-2000	thorpej	- Implement cnbell() -- ring the console bell. The cn_bell entrypoint is optional. - Add cn_bell to statically allocated consdevs as appropriate.
1.64	09-Feb-2000	nisimura	- Add missing "opt_ddb.h" to dc.c and dtop.c (oh, boy) - Nuke irrelevant "dcvar.h" and "tc.h" inclusion from dc.c - Put '#if NRASTERCONSOLE > 0' around scc_lk201_cnattach().
1.63	03-Feb-2000	nisimura	- Massive change of console initialization. Have each model its own consinit(). - Fix fbconnect() and relatives; 'struct fbinfo' is initialized only once, making sure no extraneous console resolution message is emitted.
1.62	18-Jan-2000	simonb	Only prototype and include code for scc_kbd_init() and scc_mouse_init() if NRASTERCONSOLE > 0. Fixes problem reported on port-pmax by Anders Andersson.
1.61	10-Jan-2000	simonb	Remove unneeded include files (up to 16 in two files!).
1.60	09-Jan-2000	simonb	The clean-up continues: - Make local-only function and variables static. - Move function prototypes and extern variable declarations to header files. - Delete unused variables. There's still a handful of extern declaraions that should be fixed up.
1.59	08-Jan-2000	simonb	Function prototype cleanup.
1.58	07-Jan-2000	simonb	Start of the "The Big Cleanup" - remove "ifdef alpha". This has diverged enough from the alpha scc.c that keeping any pretence of portability is not worth it.
1.57	04-Jan-2000	simonb	Ick - include pmioctl.h to get the pmEventQueue typedef needed for qvssvar.h (needed for the mouseInit() prototype). This _will_ be cleaned up soon!
1.56	30-Dec-1999	simonb	Include qvssvar.h to get mouseInput() prototype.
1.55	23-Dec-1999	ad	Rectify the jumbled naming scheme of routines in lk201.c. Function names are now lower case and prefixed by 'lk_'. XXX lk_mouseinit() is bogus. It belongs somewhere else.
1.54	08-Dec-1999	simonb	Don't use our own defines for SCCDEV or RCONSDEV - pull in <pmax/pmax/cons.h> for these values.
1.53	29-Nov-1999	ad	- When kbdMapChar() was modified to support returning multi-character mappings, it broke Ctrl-Space; fix that. - Clean up lk201.c a little.
1.52	17-Sep-1999	thorpej	branches: 1.52.2; 1.52.8; Centralize the declaration and clearing of `cold'.
1.51	24-Apr-1999	simonb	Nuke register and remove trailling white space.
1.50	20-Apr-1999	mrg	make this compile again with no rcons.
1.49	12-Apr-1999	pk	Quote "AS IS" as in the majority of Carnegy Mellon notices.
1.48	06-Apr-1999	pk	Fix a pasto in copyright text which has been procreating like rabbits..
1.47	22-Mar-1999	ad	branches: 1.47.2; Added support for cursor keys, function keys and friends. kbdMapChar now returns 'char *' to do this. Codes returned for the various keys match what 'rcons' termcap entry expects.
1.46	29-Jan-1999	kleink	Remove an incorrect (but harmless) comment.
1.45	28-Jan-1999	jonathan	Jason Thorpe's changes from PR#6848. Makes 115200 bps work on some systems. Reverse sense of #ifdef to disable 76.8k and 115.2k until we can verify it works on all 8530 chips (similar changes didnt work on a /240 in 1996).
1.44	15-Nov-1998	jonathan	* make scc_tty_init() callable when very cold: call scc_coldparam() directly. Use scc_tty_init() in scc_consinit(). Declare scc_consinit() in sccvar.h. * Remove last vestige of special-case console handling in sccparam() code. * Call scc_consinit() from findcons scc_serial() console-setup. Dont PROM for scc serial console at all.
1.43	29-Oct-1998	jonathan	Use console_debugger() hook to enter DDB.
1.42	07-Sep-1998	mhitch	branches: 1.42.2; scc_softCAR is a bit array, so set it accordingly for a serial console port (instead of using the scc line number).
1.41	04-Jul-1998	jonathan	defopt DDB.
1.40	30-Mar-1998	jonathan	* Mouse reset blocks waiting for response for mouse. Only initialize the mouse if we are using rcons as the console device.
1.39	24-Mar-1998	jonathan	Rewrite pmax console-probing code from scratch as pmax/dev/findcons.c: * Follow the same logic: look for the device the PROM is using. * If it's a framebuffer and we don't have a driver for it, try other * framebuffers in PROM search order. * If no match found, warn user and fall over to serial console. * if no serial console found, go back to PROM. Rework tc/scc.c attach routine to give cleaner initialization semantics. Prune out old 'braindamage' code.
1.38	24-Mar-1998	jonathan	Commit snapshot of pmax console rework as basepoint for 1.3.2 pullup: * Do rcons output properly, using cn_tab->cn_dev which points at rcons cdevsw entrypoints. * The pmadx console code was using keyboard (serial) device (major,minor) for raster consoles with special code in the keyboard drivers to catch output intended for consoles, pull it off the device queue, and print them via cnputc(). Ifdef out RCONS_BRAINDAMAGE. * Other minor cleanup to pmax scc driver.
1.37	22-Mar-1998	jonathan	Clone lk20.h (keycode definitions) to /sys/dev/dec. Update source pmax files accordingly. cvs remove old pmax/dev/lk201.h.
1.36	22-Mar-1998	jonathan	Elimiate whitespace KNF botches due to emacs/X cut-and-paste.
1.35	22-Mar-1998	jonathan	oops, forgot more whitespace changs and alpha_mb() -> tc_mb().
1.34	22-Mar-1998	jonathan	Whitespace, cosmetic changes against alpha/tc/scc.c 1.40.
1.33	22-Mar-1998	jonathan	More tty dialin/dialout changes (t_wopen). NB: dtop is a keyboard/mouse bus and doesn't support dialout.
1.32	05-Feb-1998	jonathan	Add local `extern' declaration of ioasic_cd, as in alpha/tc/scc.c. Missed here after the removal of ioasic_cd decl from ioasicvar.h.
1.31	12-Jan-1998	thorpej	Update for changes to config.
1.30	14-Nov-1997	jonathan	Back out read-side DELAY() in previous revision added on advice of tech-kern. Reported by Sean Davidson to cause erroneous doubling of keyboard input on a 5000/50 under load. Increasing the DELAY() from 2 to 30 doesn't help. Remove it for the 1.3 release. May cause problems with low-speed serial input, but console keyboards work properly.
1.29	08-Nov-1997	jonathan	Workaround for port-pmax/4438 (pmax kernel glass-tty console code is broken) until a proper fix is available: Perpetuate the 4.4bsd design even further. Change keyboard-driver open routines to check for an active raster console. If active, set the keyboard struct tty's t_winsize from the rcons t_winsize on first open. See pr 4438 for remaining problems and discussion of a complete fix.
1.28	21-Jul-1997	jonathan	branches: 1.28.6; Kill __BROKEN_INDIRECT_CONFIG on pmax. Based on a patch from Chris G. Demetriou, December 1996.
1.27	17-Jul-1997	jtk	use locator defines in "locators.h" to index cf_loc[]
1.26	07-Jul-1997	jonathan	DDB for mips. Add DDB interface to /sys/arch/mips/mips.. Rework heuristic stack traceback to work with DDB. Add hooks to print exception log from DDB. Add hooks from pmax console drivers: call Debugger() after break from serial console, or 'DO' key from LK-xxx.
1.25	22-Jun-1997	jonathan	* Change Sprite MACH_xxx prefix to MIPS_xxx. * Use standard mips terminology (xxx_KSEG0, xxx_KSEG1) instead of the (more meaningful) Sprite names (xxx_CACHED, xxx_UNCACHED).
1.24	16-Jun-1997	jonathan	Garbage-collect <machine/locore.h>
1.23	15-Jun-1997	mhitch	DECstation MIPS3 support: wbflush() is cpu-dependent, need declaration from machine/locore.h.
1.22	25-May-1997	jonathan	lint: add prototype for pmax serial-console inithook.
1.21	15-May-1997	mellon	Don't do rcons-specific things if no rcons pseudo-device was declared. Clean up probe-time printfs.
1.20	15-May-1997	jonathan	Merge in changes from Alpha scc driver with RCS log message: > revision 1.33 > date: 1997/05/15 02:15:55; author: thorpej; state: Exp; lines: +8 -4 > - In sccmatch(), check any user-specified offset, allowing scc unit numbers > to be nailed down. From Ken Hornstein <kenh@cmf.nrl.navy.mil>, PR #3626, > slightly modified to allow wildcarded offsets. > - Blow away the cf->cf_unit check in sccmatch(); it's bogus. Also gc usused references to NSCC and #include "scc.h"
1.19	26-Apr-1997	jonathan	Stop ignoring DCD transitions on ioasic SCC serial lines. From entropy@zippy.bernstein.com>.
1.18	16-Oct-1996	jonathan	Cleanups, and convergence with the Alpha driver: * kill scc_tty[] and needs-count. * Add usable-when-cold version of sccparam(). * Add pre-autconf() console initialization entrypoint. * remove lint for gcc -Wall * wbflush() -> tc_mb() all but the last of which have been fed through cgd and committed to the Alpha scc driver.
1.17	13-Oct-1996	christos	backout previous kprintf change
1.16	11-Oct-1996	christos	printf -> kprintf, sprintf -> ksprintf
1.15	07-Sep-1996	mhitch	The MAXINE serial console is on scc0 (the only SCC on the MAXINE) instead of scc1. Fix the check of which scc to initialize the console serial line so that the MAXINE serial console will work.
1.14	02-Sep-1996	mycroft	tty stop functions really should return void, not int, and certainly not both.
1.13	16-Jun-1996	mhitch	Do tty_attach() for serial lines.
1.12	29-May-1996	mhitch	Fix autoconfiguration stuff to more closely match the alpha - primarily the IOASIC attached devices. The DS3100 will now configure properly. Fix the DS5000/25 IOASIC table entry for the RTC so the RTC interrupts get enabled. Fix up a moved include file.
1.11	17-Mar-1996	jonathan	branches: 1.11.4; Additional fixes to complete the NetBSD/1.1B config changes: change IOASIC cfdriver references from "ioasiccd" to "ioasic_cd"
1.10	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.
1.9	08-Feb-1996	jonathan	Add serial-console support that works with `new-style' (config.new) autconf code. Substantially the same code tested on a 5k/240. Should work on a 5k/1xx. Not tested on a MAXINE, where the single unit may break the PROM-channel-number to driver-channel-number mapping.
1.8	02-Feb-1996	mycroft	Fix #includes.
1.7	31-Jan-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'.
1.6	29-Jan-1996	jonathan	Re-write Decstation turbochannel autoconfiguration code to use the machine- independent TC support in sys/dev/tc/tc.c and sys/dev/tc/tcvar.h: * Change the tc autoconfiguration tables to use a struct tc_attach_args instead of the ad-hoc structure. * Change all pmax device drivers to use a `struct confargs' that's assignment-compatible with sys/dev/tc/tcvar.h `struct tcdev_attach_args'. Devices that can be present on a TC or as ioctl asic/mainbus builtins use the same `struct confargs'. * Eliminate the `BUS_CVTADDR()' macros which the pmax port inherited from an old, now-obsolete sys/arch/alpha snapshot. * Update the comments and debugging code in interrupt handlers to be consistent with the machine-independent TC support. Other commits that overlap the same source files include: re-enabling clock-tick interrupts earlier, and counting hardclock ticks for vmstat -i.
1.5	29-Sep-1995	jonathan	Add speed entries for 7200 and multiples. Add as-yet-unused speed entries for a 1x SCC clock, up to 200 Kbits. Remove old top-bit-means-delay code, since nothing seems to need it, and it apparently partially broke lk-201 initialization anyway.
1.4	25-Sep-1995	jonathan	Fix SCC bug that broke getty on pmax SCC lines: if RAW and LITOUT were both off, haracters with their top bit clear were interpreted as a delay. This (strange) behaviour is still available if SCC_PARITY_MEANS_DELAY is defined.
1.3	25-Sep-1995	jonathan	Force a delay after calling SCC_WRITE_DATA() to give the chip registers time to settle. DELAY(2) is reportedly enough. Without the delay, output characters are occasionally doubled.
1.2	11-Sep-1995	jonathan	Change pmax rcons and low-level serial drivers to support the old-style pmax polled input for cn_getc(). Needed because the input side of rcons is not initialized in time for GENERIC kernels to use it to read a root/swap devicename from /dev/console.
1.1	22-Aug-1995	jonathan	Move the pmax scc driver from sys/arch/pmax/dev to sys/arch/pmax/tc, as it's a driver for a device under a TC IOASIC. The Alpha port also has its scc driver in tc/scc.c, and the pmax driver scc is nearly the same as the Alpha.

1.52.2.1	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.

1.70.8.5	03-Jul-2002	nathanw	Whitespace.
1.70.8.4	24-Jun-2002	nathanw	Curproc->curlwp renaming. Change uses of "curproc->l_proc" back to "curproc", which is more like the original use. Bare uses of "curproc" are now "curlwp". "curproc" is now #defined in proc.h as ((curlwp) ? (curlwp)->l_proc) : NULL) so that it is always safe to reference curproc (dereferencing curproc is another story, but that's always been true).
1.70.8.3	01-Apr-2002	nathanw	Catch up to -current. (CVS: It's not just a program. It's an adventure!)

1.70.4.2	13-Oct-2001	fvdl	Revert the t_dev -> t_devvp change in struct tty. The way that tty structs are currently used (especially by console ttys) aren't ready for it, and this will require quite a few changes.
1.70.4.1	10-Oct-2001	fvdl	Convert all remaining devices.
1.70.2.2	10-Oct-2002	jdolecek	sync kqueue with -current; this includes merge of gehenna-devsw branch, merge of i386 MP branch, and part of autoconf rototil work

1.7	03-Feb-2000	nisimura	branches: 1.7.44; 1.7.58; 1.7.62; - Massive change of console initialization. Have each model its own consinit(). - Fix fbconnect() and relatives; 'struct fbinfo' is initialized only once, making sure no extraneous console resolution message is emitted.
1.6	09-Jan-2000	ad	- Protect against multiple includes. - Spacing.
1.5	09-Jan-2000	simonb	The clean-up continues: - Make local-only function and variables static. - Move function prototypes and extern variable declarations to header files. - Delete unused variables. There's still a handful of extern declaraions that should be fixed up.
1.4	08-Jan-2000	simonb	Function prototype cleanup.
1.3	15-Nov-1998	jonathan	branches: 1.3.10; * make scc_tty_init() callable when very cold: call scc_coldparam() directly. Use scc_tty_init() in scc_consinit(). Declare scc_consinit() in sccvar.h. * Remove last vestige of special-case console handling in sccparam() code. * Call scc_consinit() from findcons scc_serial() console-setup. Dont PROM for scc serial console at all.
1.2	19-May-1996	jonathan	branches: 1.2.16; 1.2.20; Add port number encodings.
1.1	04-Aug-1995	jonathan	Add header files with prototyped declarations of the serial-chip hooks used by old-style pmax console configuration.
1.2.20.1	15-Oct-1998	nisimura	- new asc driver combined with MI NCR53C9x and MI SCSI. - import zs_ioasic.? from NetBSD/alpha. - NWSCONS drivers for various DECstations. - squash tc_xxx.c into single tc_machdep.c

1.1	15-Oct-1998	nisimura	branches: 1.1.2; file sfb.c was initially added on branch nisimura-pmax-wscons.
1.1.2.2	30-Oct-1998	nisimura	- Migrate to MI TURBOchannel codes.
1.1.2.1	15-Oct-1998	nisimura	- new asc driver combined with MI NCR53C9x and MI SCSI. - import zs_ioasic.? from NetBSD/alpha. - NWSCONS drivers for various DECstations. - squash tc_xxx.c into single tc_machdep.c
1.15	30-Mar-1998	jonathan	Remove ancient non-MI pmax/tc/tc.c code.
1.14	22-Jun-1997	jonathan	* Change Sprite MACH_xxx prefix to MIPS_xxx. * Use standard mips terminology (xxx_KSEG0, xxx_KSEG1) instead of the (more meaningful) Sprite names (xxx_CACHED, xxx_UNCACHED).
1.13	16-Jun-1997	jonathan	Remove the machConst.h (wrapper for Sprite-derived source), and all #includes <machine/machConst.h> uses. Other header files now include <mips/cpuregs.h> where necessary.
1.12	13-Oct-1996	christos	backout previous kprintf change
1.11	11-Oct-1996	christos	printf -> kprintf, sprintf -> ksprintf
1.10	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).
1.9	02-Feb-1996	mycroft	Fix #includes.
1.8	29-Jan-1996	jonathan	Re-write Decstation turbochannel autoconfiguration code to use the machine- independent TC support in sys/dev/tc/tc.c and sys/dev/tc/tcvar.h: * Change the tc autoconfiguration tables to use a struct tc_attach_args instead of the ad-hoc structure. * Change all pmax device drivers to use a `struct confargs' that's assignment-compatible with sys/dev/tc/tcvar.h `struct tcdev_attach_args'. Devices that can be present on a TC or as ioctl asic/mainbus builtins use the same `struct confargs'. * Eliminate the `BUS_CVTADDR()' macros which the pmax port inherited from an old, now-obsolete sys/arch/alpha snapshot. * Update the comments and debugging code in interrupt handlers to be consistent with the machine-independent TC support. Other commits that overlap the same source files include: re-enabling clock-tick interrupts earlier, and counting hardclock ticks for vmstat -i.
1.7	03-Jan-1996	jonathan	arch/pmax/tc -> dev/tc, pass 1: Eliminate pmax/tc/tc.h. Use dev/tc headers for pmax port. Change pmax TC autoconfig tables to use structs (mostly) compatible with dev/tc/tcvar.h. Move TC console search to tc.c.
1.6	28-Dec-1995	jonathan	Add untested, partial support for Decsystem 5100 (mipsfair).
1.5	09-Oct-1995	jonathan	Fix bugs in the turbochannel config table for MAXINE (personal decstation).
1.4	25-Sep-1995	jonathan	Update pmax kernel to compile with -Werror: Update TURBOChannel and ioasic interrupt-establish routines to pass on their device argument as a "void *", since that's how all the pmax interrupt handlers are declared.
1.3	12-Sep-1995	jonathan	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.)
1.2	10-Aug-1995	jonathan	Remove extraneous debugging printf()s when running on processors this code has been tested on.
1.1	07-Aug-1995	jonathan	New-style config (config.new) autoconfiguration code for Decstation turhsturbochannel machines. Lifted wholesale from cgd's Alpha turbochannel code, with changes that reflect the slightly different bus topology and `slot' numbering on Decstations.
1.3	03-Jan-1996	jonathan	Remove pmax/tc/tc.h; use dev/tc/tcvar.h instead.
1.2	28-Dec-1995	jonathan	Use machine-independent TurboChannel include files from dev/tc. Add machine-dependent TC definitions in pmax/include/tc_machdep.h.
1.1	07-Aug-1995	jonathan	New-style config (config.new) autoconfiguration code for Decstation turhsturbochannel machines. Lifted wholesale from cgd's Alpha turbochannel code, with changes that reflect the slightly different bus topology and `slot' numbering on Decstations.
1.7	04-Jun-2000	cgd	Implement the more flexiable `evcnt' interface as discussed (briefly) on tech-kern and now documented in evcnt(9).
1.6	29-Feb-2000	nisimura	branches: 1.6.2; - Have SYS_DEV_xxx device cookie symbols to select and install proper interrupt handlers into intrtab[] array, rather than the idea of devices in 'psuedo' TURBOchannel slots. - Nuke symbols for psuedo TC slots. - Abandon never/unlikely used intr_disestablish()s.
1.5	09-Jan-2000	ad	RCS ID police.
1.4	01-Dec-1999	nisimura	Arrange comment descriptions for internals of TC DECstations.
1.3	15-Nov-1999	nisimura	Very large scale change to sweep obstracles to remove 3MAX IOASIC disguise. - Rework ibus device configuration and interrupt handler assignment. - Remove TC device exposure in 'mainbus.c' - Squash 'ibus_{3100,5100}.c' into a file; it can not cope with 3max. - 'struct confargs' -> 'struct mainbus_attach_args' Now about to remove tc_slot_info[] and tc_enable_interrupt inherited from 4.4BSD.
1.2	12-Mar-1999	nisimura	branches: 1.2.8; 1.2.14; - Nuke old leftover bogocities, round one; externs for non-existent functions, less-intuitive #define's in inappropriate header files.
1.1	19-Apr-1998	jonathan	branches: 1.1.4; Rework pmax turbochannel config, as suggested by Jason Thorpe. Also make TC framebuffer-console search table-driven. Does not yet include "tcasic" layer; there's no such hardware on DECstations and nothing for a tcasic layer to do.
1.1.4.1	15-Oct-1998	nisimura	- new asc driver combined with MI NCR53C9x and MI SCSI. - import zs_ioasic.? from NetBSD/alpha. - NWSCONS drivers for various DECstations. - squash tc_xxx.c into single tc_machdep.c

1.25	25-Jul-1999	ad	Change the way fb devices are configured and attached: - 'struct fbsoftc' created, which points to a 'struct fbinfo' - 'struct fbinfo' for each device is allocated with fballoc() This means: - Console device doesn't get different 'struct fbinfo' at attach - Console device doesn't get initialized twice - Color rcons now works - The current Xserver MUST BE REBUILT.
1.24	24-Jun-1999	ad	Remove a few entries for nonexistant TC graphics boards.
1.23	24-Apr-1999	simonb	Nuke register and remove trailling white space.
1.22	13-Apr-1999	ad	Added console initalization glue to allow `px' device to function as the console.
1.21	22-May-1998	thorpej	branches: 1.21.4; 1.21.12; Provide bus_space and bus_dma data structures to the TurboChannel bus.
1.20	20-Apr-1998	jonathan	* Fix typo in ROM name of mfb (PMAG-AA) * Use TC_ROM_LLEN instead of constant, add space for sentinel. * Don't print fb dimensions at console-probe time.
1.19	19-Apr-1998	jonathan	Rework pmax turbochannel config, as suggested by Jason Thorpe. Also make TC framebuffer-console search table-driven. Does not yet include "tcasic" layer; there's no such hardware on DECstations and nothing for a tcasic layer to do.
1.18	30-Mar-1998	mrg	<pmax/pmax/trap.h> has been obsoleted...
1.17	25-Mar-1998	jonathan	* Use new defopt model-specific options and opt files. Replace all DS5000_* and DS3100 ifdefs with ifdefs on DEC_ options. * Use MI declarations, not pmax-specific, in model-specific init that uses baseboard (ioasic) registers. * Further cleanup of machdep.c. Clock-tick still needs more thought. * Use 'ibus' names for 3100 baseboard devices in MI code.
1.16	25-Mar-1998	jonathan	Split sys/arch/pmaxpmax/{machdep.c,trap.c} as suggested by Jason Thorpe: * add "Platform" support inpmax/pmax/sysconf.c and pmax/include/sysconf.h (based on Alpha cpuconf.[ch], with a namechange to avoid clashes with support for models of MIPS cpus. They differ more than Alphas). * For each supported model of DECstation, create a separate file with the support for that model. Use model codenames, since support is really baseboard-specific and CPU daugherboards can change. Move code from machdep.c and pmax_trap.c, Add sysconf (nee "cpuconf") support. * Rename model-specific functions to match sysconf names. * Clean up autoconf.c. Use platform callbacks. * Retire pmax_trap.c. Leaves I/O bus configuration and console configuration untouched.
1.15	08-Nov-1997	jonathan	Delete ancient warning printf() from when this code hadn't been tested on 3MIN or MAXINE motherboards. Add __KERNEL_RSID while we're here.
1.14	24-Sep-1997	mhitch	branches: 1.14.2; Add an entry for the bus_space_tag in the TC attach argument tables. Fixes PR #4100.
1.13	22-Jun-1997	jonathan	branches: 1.13.4; * Change Sprite MACH_xxx prefix to MIPS_xxx. * Use standard mips terminology (xxx_KSEG0, xxx_KSEG1) instead of the (more meaningful) Sprite names (xxx_CACHED, xxx_UNCACHED).
1.12	16-Jun-1997	jonathan	Remove the machConst.h (wrapper for Sprite-derived source), and all #includes <machine/machConst.h> uses. Other header files now include <mips/cpuregs.h> where necessary.
1.11	15-Jun-1997	mhitch	Use TC_SPEED* for turbochannel speed values (keeps me from being confused more than I am).
1.10	24-May-1997	jonathan	Lint: include prototypes for TurboChannel framebuffer console-init functions. include prototype for printf() and panic() and delint calls.
1.9	13-Oct-1996	christos	backout previous kprintf change
1.8	11-Oct-1996	christos	printf -> kprintf, sprintf -> ksprintf
1.7	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).
1.6	27-Aug-1996	jonathan	* Add initialization of colourmap array when using mfb as a console. * Add interrupt handler for 3MIN, where we cannot disable TC slot interrupts. * Change mfbinit() signature to match other (pmax) TC framebuffer init routines. * TODO after 1.2: add {cfb,mbf,sfb}var.h. Declare init functions there.
1.5	21-Aug-1996	jonathan	Fix sfbinit() call to pass four arguments, not three, matching the signature in sfb.c, which was changed to support multiple sfb devices.
1.4	17-Jun-1996	jonathan	Fix typo, colon instead of semicolon when DS_5000_25 is not defined.
1.3	15-Jun-1996	jonathan	Fix for PR #1828 and partial fix for PR #2548: * Eliminate the #ifdef DS5000 and kernel config option DS5000 altogether. option DS5000 was a hangover from 4.4bsd/pmax; it's never been clear if it means "support for DS5000/200" or "support for any TC machine". This implictly fixes pr 1828. * Use the "tc.h" and NTC generated by config for a "tc? at mainbus" where appropriate, intsead of #ifdef DS5000. * Canonicalize the spelling of kernel options that enable support for particular models. Use DS5000_25 for the Personal Decstation aka MAXINE aka KN02-ca DS5000_100 for the 5000/1xx series aka KMIN aka KN02-ba DS5000_200 for the 5000/200 aka 3MAX aka KN02 DS500_240 for the 5000/240 aka 3MAXPLUS aka KN03 and change DS_5000_xxx to DS5000_xxx everywhere. * Wrap the interrupt handlers for each model in the appropriate #ifdef, instead of wrapping all of them with "#ifdef DS5000". * Wrap the TC autoconfig for each model in the appropriate #ifdef.
1.2	29-May-1996	mhitch	Fix autoconfiguration stuff to more closely match the alpha - primarily the IOASIC attached devices. The DS3100 will now configure properly. Fix the DS5000/25 IOASIC table entry for the RTC so the RTC interrupts get enabled. Fix up a moved include file.
1.1	27-Feb-1996	jonathan	branches: 1.1.4; TurboChannel bus auto-configuration tables, and TurboChannel pre-autoconfig probe functions for console framebuffers, rewritten to work with the machine-independent TC support in sys/dev/tc.
1.1.4.4	09-Sep-1996	thorpej	Pull up diffs between revs 1.4 and 1.6, by request from Jonathan Stone.

1.26.2.1	20-Nov-2000	bouyer	Remove files that are no longer on the trunck
1.33	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.
1.32	12-Dec-2016	flxd	branches: 1.32.8; Clean-up (remove redundant declarations, concentrate checks).
1.31	16-Nov-2016	macallan	switch to common MIPS bus_space and bus_dma tested by flxd@
1.30	09-Jun-2015	matt	branches: 1.30.2; #include either <sys/cpu.h> or <mips/cpuregs.h> as needed

1.27	04-Jun-2011	tsutsui	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...
1.26	20-Feb-2011	matt	branches: 1.26.2; Merge forward from matt-nb5-mips64. New interrupt code. mips64 support for DS5000/260.
1.25	16-Mar-2009	dsl	branches: 1.25.4; 1.25.6; 1.25.8; ANSIfy functions with function-pointer arguments
1.24	14-Mar-2009	dsl	ANSIfy another 1261 function definitions. The only ones left in sys are beyond by sed script! (or in sys/dist or sys/external) Mostly they have function pointer parameters.
1.23	14-Mar-2009	dsl	Change about 4500 of the K&R function definitions to ANSI ones. There are still about 1600 left, but they have ',' or /* ... */ in the actual variable definitions - which my awk script doesn't handle. There are also many that need () -> (void). (The script does handle misordered arguments.)
1.22	14-Mar-2009	dsl	Remove all the __P() from sys (excluding sys/dist) Diff checked with grep and MK1 eyeball. i386 and amd64 GENERIC and sys still build.
1.21	26-May-2008	nisimura	branches: 1.21.6; 1.21.12; 1.21.16; - 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
1.20	31-Jul-2006	ad	branches: 1.20.58; 1.20.60; 1.20.62; 1.20.64; tcfb_cnattach(): pass the slot address through TC_PHYS_TO_UNCACHED() in case the PROM hands us a physical or KSEG0 address.
1.19	29-Jul-2006	ad	Remove RASTERCONSOLE support from the pmax port.
1.18	11-Dec-2005	christos	branches: 1.18.4; 1.18.8; merge ktrace-lwp.
1.17	13-Dec-2003	ad	branches: 1.17.16; Add drivers for the desktop bus, DC-7085 and pm display. Make it possible to select between rcons or wscons at compile time. Ok'ed by simonb.
1.16	02-Oct-2002	thorpej	branches: 1.16.6; Use CFATTACH_DECL().
1.15	27-Sep-2002	thorpej	Declare all cfattach structures const.
1.14	19-Sep-2001	thorpej	branches: 1.14.4; 1.14.10; Adjust to use <dev/sun/fbio.h>
1.13	17-Feb-2001	tsutsui	branches: 1.13.2; 1.13.4; white space nits.
1.12	06-Jun-2000	nisimura	branches: 1.12.4; Add a missing parenthesis and correct the function return value declaration.
1.11	04-Jun-2000	cgd	Implement the more flexiable `evcnt' interface as discussed (briefly) on tech-kern and now documented in evcnt(9).
1.10	29-Feb-2000	nisimura	branches: 1.10.2; Cleanup warning comment which is now irrelevant. Reorder codes.
1.9	29-Feb-2000	nisimura	- Have SYS_DEV_xxx device cookie symbols to select and install proper interrupt handlers into intrtab[] array, rather than the idea of devices in 'psuedo' TURBOchannel slots. - Nuke symbols for psuedo TC slots. - Abandon never/unlikely used intr_disestablish()s.
1.8	03-Feb-2000	nisimura	- Massive change of console initialization. Have each model its own consinit(). - Fix fbconnect() and relatives; 'struct fbinfo' is initialized only once, making sure no extraneous console resolution message is emitted.
1.7	14-Jan-2000	simonb	Redo interrupt establishment, based in part on work on the [nisimura-pmax-wscons] branch and suggestions from Toru Nisimura: - Remove bogus tc_slot_info[] name for interrupt handling array and replace with simplified struct intrhand intrtab[] array. - Add intr_establish() and intr_disestablish() function pointers to struct platform and initialise this in each model-specific initialisation, and remove global tc_enable_interrupt function pointer. - Remove model-specific function declarations from ibus/ibusvar.h. This is functionally identical to the current scheme, and doesn't yet try to commonise interrupt establishment by bus type as the [nisimura-pmax-wscons] branch does. Also, move cpuspeed variable from autoconf.c to machdep.c
1.6	09-Jan-2000	ad	RCS ID police.
1.5	09-Jan-2000	simonb	The clean-up continues: - Make local-only function and variables static. - Move function prototypes and extern variable declarations to header files. - Delete unused variables. There's still a handful of extern declaraions that should be fixed up.
1.4	08-Jan-2000	simonb	Function prototype cleanup.
1.3	17-Nov-1999	nisimura	branches: 1.3.2; 1.3.4; Consistent panic messages when erroneous kernel configurations are found.
1.2	16-Nov-1999	nisimura	Fix a typo in PX TC device identification case analysis.
1.1	15-Nov-1999	nisimura	Very large scale change to sweep obstracles to remove 3MAX IOASIC disguise. - Rework ibus device configuration and interrupt handler assignment. - Remove TC device exposure in 'mainbus.c' - Squash 'ibus_{3100,5100}.c' into a file; it can not cope with 3max. - 'struct confargs' -> 'struct mainbus_attach_args' Now about to remove tc_slot_info[] and tc_enable_interrupt inherited from 4.4BSD.
