* Snap the sample rate when setting it, and remember only the time constant.
* Set the time constant when changing between play/record.
* Always return the actual sample rate with AUDIO_GETINFO.
* Add more delays while writing registers.
* Replace sc_dma{in,out}_inprogress with sc_dmadir.
* Eliminate the need for sc_locked.
* Add more DPRINTF()s.
multiple packets were being received due to not flushing newly received
packets from the ring buffer between receiving an interupt and pulling

based on "#ifdef MELLON": examine the framebuffer dimensions in the
fb softc, and initialize the x-axis offset appropriately.
User-level changes to (e.g.) an Xserver are still needed to work
on an SFB.
- Interrupt service routines now take a pointer to
the device's softc, rather than a unit number.
- Interrupt handling code in locore.s condensed. Only
remaining "special" handlers are lev0 (spurious),
lev1 (HIL; don't ask), lev6 (clock), and lev7 (NMI).
Only remaining hard-coded device driver reference in
locore is HIL. (clock doesn't count...)
- "dcafastservice" eliminated. DCA driver has new mechanism
to guarantee prompt interrupt service at any ipl (not
just level 5).
- Interrupt code pulled out of autoconf.c and machdep.c and
placed in new file, isr.c
to a softc, rather than a unit number. Add a "dq_softc" member
to struct devqueue; this is a temporary measure until the
dma/controller/device callback spaghetti is untangled.
YAY! No more need for dcafastservice!
HIL: squish instances of "(void) splhil()" and "(void) spl0();".
The dtop driver no longer requires the "needs-count" flag.
Fix a panic in boot-time interrupt establish. The "generic" pmax
interrupt-establish code assumes that all interrupt args are new-config
device structs accessed via a struct cfdriver. Make it so.
number before attempting to load the Macintosh partition info. If the
first 32-bits of block 0 contain the BSD disklable magic number, treat
it as a NetBSD disklabel.
When loading the Macintosh partition map, check the first 32 partitions
for the root, usr, and swap partitions--instead of the first 8. Still
only allows 8 total partitions for NetBSD use.
the MI 5380 driver. It has been verified to work on the IIx, IIsi,
and IIci only, but should work with any Macintosh 5380-based SCSI
controller.
- This driver is _not_ intended to be a general purpose replacement
for the `ncrscsi' driver. It is an alternative for those having
problems with that driver.
- Disconnect/reselect doesn't (yet) work, so don't expect SCSI tape
or magneto-optical disk drives to function properly.
rather than SEEKCOMPLETE before retrying the operation. If implied seeks
are being used, the state is set to DOIO (no change). This is why I
couldn't reproduce the disk_unbusy() panic on my SS2; it uses implied
seeks. Patch from John F. Woods <jfw@jfwhome.funhouse.com>
retrying the operation. Fixes disk_unbusy() imbalance and really seems
like the right thing to do in case it was the seek that failed. Takes
care of PR #1985. Patch from John F. Woods <jfw@jfwhome.funhouse.com>
This clearly needs to be fixed. I would like to declare it:
__pure u_int pmap_page_index __P((vm_offset_t));
but at least the arm port wants it signed [since it tests for -1 all over
the place]. Can we have this fixed please?
detatch everywhere else. Reverted to the english spelling.
Also fixed the rest of the prototype warnings while I was at it.
ic/ncr5380sbc.c: Don't declare Debugger()... I have to clean this
everywhere :-(

intent for the value of the C_REL constant was 0xc0. Testing has turned
up no adverse effect on tape or disk devices, and in fact this change
apparently makes my 9145 tape work as expected. (!) Closes PRs 1874 and

specific probe function did not specify it. It picks the same address
as mmap() does for a non-fixed map at address 0. See also the comment
around a similar line of code in vm/vm_mmap.c.
- moved disk_busy() call from xdstrategy() to xdc_startbuf()
[prevents disk_unbusy panic when disk is loaded (if no
free IOPBs, xdstrategy() would queue the buffer for pickup
by xdcintr() but xdcintr() would never call disk_busy().
xdc_startbuf() is a better place since all bufs are routed
through here] problem detected by girish@dworkin.wustl.edu,
diagnosed and corrected by me.
- move disk_unbusy() call in xdc_remove_iorq() before the call to
XDC_FREE() [don't want to access a data structure that was just put
on a free list]

5k/1xx. Not tested on a MAXINE, where the single unit may break the
PROM-channel-number to driver-channel-number mapping.

trunc_page(), etc.)
to be passed as well as the fp frame.
FPE<->kernel glue code now builds a trapframe structure for passing in

Signal delivery during FP emulation now works correctly.
* add a new enum decstation_intr_t to trap.c, naming each instrumented
interrupt symbolically, and used to index into intrcnt[]. Change the
model-specific interrupt handlers to use the decstation_intr_t when
updating interrupt counters.
* add instrumentation to the kmin and maxine interrupt handlers.
* fix a bug that counted each hardclock interrupts on the kn02 twice.
The hardcoded mapping from locore names to units is gross; but these
counters will hopefully be useful in identifying interrupt hot-spots
and PPP problems on the 3MIN.

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.
