Added bdev and cdev args to dsopen().
drivers:
Fixed device names, links, minor numbers and modes.
wd.c:
Started actually supporting devfs.
diskslice.h:
Added devfs tokens to structs (currently 576 of them per disk! :-().
subr_diskslice.c:
Create devfs entries in dsopen() and (unsuccessfully) attempt to make
them go away at the right times. DEVFS is #undefed at the start so
that this shouldn't cause problems.
fd and wt drivers need bounce buffers, so this normally saves 32K-1K
of kernel memory.
Keep track of which DMA channels are busy. isa_dmadone() must now be
called when DMA has finished or been aborted.
Panic for unallocated and too-small (required) bounce buffers.
fd.c:
There will be new warnings about isa_dmadone() not being called after
DMA has been aborted.
sound/dmabuf.c:
isa_dmadone() needs more parameters than are available, so temporarily
use a new interface isa_dmadone_nobounce() to avoid having to worry
about panics for fake parameters. Untested.
overrun by 2 pages.
Fixed the (unused) values returned from device attach functions.
Fixed checking of unit number in device open functions - don't load bad
pointers or print error messages about the contents of bad pointers.
Removed unused #includes.
asc.c:
Fixed premature setting of flags in ascopen() - copied the better order
in gscopen().
gsc.c:
Fixed conflict handling for drq:
- fail the probe if the configured drq doesn't match the actual drq.
- set the configured drq to match the actual drq in the autoconfig case.

Speed up for vfs_bio -- addition of a routine bqrelse to greatly diminish
overhead for merged cache.
Efficiency improvement for vfs_cluster. It used to do alot of redundant
calls to cluster_rbuild.
Correct the ordering for vrele of .text and release of credentials.
Use the selective tlb update for 486/586/P6.
Numerous fixes to the size of objects allocated for files. Additionally,
fixes in the various pagers.
Fixes for proper positioning of vnode_pager_setsize in msdosfs and ext2fs.
Fixes in the swap pager for exhausted resources. The pageout code
will not as readily thrash.
Change the page queue flags (PG_ACTIVE, PG_INACTIVE, PG_FREE, PG_CACHE) into
page queue indices (PQ_ACTIVE, PQ_INACTIVE, PQ_FREE, PQ_CACHE),
thereby improving efficiency of several routines.
Eliminate even more unnecessary vm_page_protect operations.
Significantly speed up process forks.
Make vm_object_page_clean more efficient, thereby eliminating the pause
that happens every 30seconds.
Make sequential clustered writes B_ASYNC instead of B_DELWRI even in the
case of filesystems mounted async.
Fix a panic with busy pages when write clustering is done for non-VMIO
buffers.
Save 112K for SB, 64K for PAS and 64K for MSS.
Since PAS use SB emulation, 176K normally saved for it.
Few minor optimizations added like in Linux driver.
When you start tracker and produce some heavy disk activity,
output interrupts becomes lost and I don't know how to solve it
finally. Newly added code at least allows recovery after timeout.
2) Use CURSIG(curproc) in PROCESS_ABORTING instead of junk code was there.
3) Reanimate timeout code in DO_SLEEP by setting WK_TIMEOUT flag
which is never set in old code.
4) DO_SLEEP: set aborting flag on interrupting singnals as supposed, not
on signals which do nothing as in old code.
5) Cleanup WAKE_UP macro, WK_WAKEUP not used.
6) Remove wrong typecasts in sleep/wakeup code.
This random address can be matched (with some probability) with another
sleep addresses from other drivers, which can cause strange sleep/wakeup
sequence. Rewrite this ugly code to do the right thing.
Add more features to the one remaining to handle the job:
+ signed quantity.
# alternate format

n numeric in (argument specified) default radix.
Fix the DDB debugger to use these.
Use vprintf in debug routine in pcvt.
The warnings from gcc may become more wrong and intolerable because

in the future, these drivers won't need to maintain an array of
configured units. They still need to because ISA interrupt handlers
take a unit number. :(
Pass "softc" pointers instead of unit numbers to many functions that
did a conversion of unit->softc anyway.

whether of not to automatically #define EXCLUDE_AUDIO; MSS is a real

This fixes the very confusing condition where having all of this:

opl0: <Yamaha OPL-3 FM>

Also remove an unnecessary newline in the printf() message for the
'gus0' device shown above so that we don't wind up printing a blank
line between mss0 and gus0.

to enable IP forwarding, use sysctl(8). Also did the same for IPX,
which involved inventing a completely new MIB from whole cloth (which
I may not quite have correct); be aware of this if you use IPX forwarding.
(The two should never have been controlled by the same option anyway.)
Simplify the initialization of adapters by pulling all card specific
initialization to the card specific modules.
Update comments and fix formating.
Pass struct ahc_data*'s to functions instead of unit numbers.
Take advantage of the quad word alignment of SCB fields.
Adapt to new sequencer changes:
1) Waiting scb list no longer has a tail.
2) Fill the message buffer as appropriate during a parity error.
3) Count all of the SGs involved in a residual instead of just
the current one.
The reset/abort code still needs a lot of work.

ports tree does use /dev/io anyway, so this might be replaced by
another scenario some day.
looking at a high resolution clock for each of the following events:
function call, function return, interrupt entry, interrupt exit,
and interesting branches. The differences between the times of
these events are added at appropriate places in a ordinary histogram
(as if very fast statistical profiling sampled the pc at those
places) so that ordinary gprof can be used to analyze the times.
gmon.h:
Histogram counters need to be 4 bytes for microsecond resolutions.
They will need to be larger for the 586 clock.
The comments were vax-centric and wrong even on vaxes. Does anyone
disagree?
gprof4.c:
The standard gprof should support counters of all integral sizes
and the size of the counter should be in the gmon header. This
hack will do until then. (Use gprof4 -u to examine the results
of non-statistical profiling.)
config/*:
Non-statistical profiling is configured with `config -pp'.
`config -p' still gives ordinary profiling.
kgmon/*:
Non-statistical profiling is enabled with `kgmon -B'. `kgmon -b'
still enables ordinary profiling (and distables non-statistical
profiling) if non-statistical profiling is configured.
