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.

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.

Use ${TOOL_AWK} instead of ${AWK} or plain "awk" in make commands.

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.

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.

branches: 1.60.4;
Remove register declarations.

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.

Unnecessary to enclose device driver body with #if NASC > 0.

Merge IOASIC register definitions.

- 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.

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).

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.

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.

don't use variables declared _inside_ DEBUG in code _outside_ DEBUG

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.

Adjust for changes in config.

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.

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

change some include files and structure names in the low level scsi drivers.

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.

Fill in sc_link.max_target

backout kprintf changes

printf -> kprintf, sprintf -> ksprintf

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.

* 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) 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.

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).

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 *.

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.

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.

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).

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.

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".

branches: 1.19.2;
* Fix formatstr/argument mismatches in diagnostic printf()s.
* Change MachEmptyWriteBuffer() to wbflush(). Should use TC mi names tc_mb(),

* Add prototyped forward decl for asc_Dumplog() and add an explicit void
return type.
* Remove unused variables.

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".

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.

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.

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.

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.)

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.

Update DECstation drivers to use new-style config, removing
old-style config support, except for SCSI disks and tapes.

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.

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.

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.

Get rid of hook for dk_establish() - pmax will now use device_register().

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.

Use bus_space_{write,read} for IOASIC register access.

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.

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!)

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.

Adapt to the new scsipi_adapter interface.

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.

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.

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

Disable several informational messages dealing with non-empty FIFO conditions,
but allow enabling with ASC_DIAGNOSTIC for troubleshooting.

* 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.

Improve am7930 family drivers to share more code.
audioamd(4) on sparc, vsaudio(4) on vax, and bba(4) are.

- 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@.

Fix white space and indent.

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.

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.

Use C99 style struct initializer to audio_hw_if.

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!)

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.

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

PAGE_SIZE -> IOASIC_DMA_BLOCKSIZE in one last place. From Izumi Tsutsui.

Back out previous. It is no longer needed, as both the Alpha
and DECstation IOASIC drivers clear the appropriate interrupts
in the dispatch routine.

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>.

- 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.

remove include of <vm/vm.h>. <vm/vm.h> -> <uvm/uvm_extern.h>

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.

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

Merge thorpej-cfargs2.

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?).

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.

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

"options FOO=xxx"). options that take a value were converted to
defparam recently.

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.

Initial revision

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.

Add a hardware dependent initialization function lehwinit()

restructure to take advantage of config's (relatively) new 'attach'
specifiers. Many #ifdefs and much other nastiness removed.

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).

fixes for -Wall -Wmissing-prototypes:
prototype the forward declaration of lewritereg().

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).

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) 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.

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.

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.

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.

This is mandatory for some archs. See, e.g.:

http://www.nerv.org/netbsd/?q=id:20210511T013030Z.013443cc790088147e4beed43f53dedabeaf9312

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).

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!)

- 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?).

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

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.

autoconfiguration information for the TurboChannels System ("IOCTL") ASIC
found in many DECstations and all of the TC-bus Alphas. This is
provided so that the machine-independent TC if_le driver will be able
to use it.

Move sys/dev/tc/mcclockvar.h -> sys/dev/dec/mcclockvar.h.
Update pmax clock code.

Clone Alpha ``cpu-independent'' clock API headers into sys/dev/tc/,
to share them with pmax.

clean up NetBSD RCS ID strings

branches: 1.2.2;
fix copyrights

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...

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

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.

- Simplify wherever possible; don't pass along arguments that aren't
actually needed.
- Don't be explicit about what interface attribute is attaching if
