(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.
packets. It's not clear whether latency will be affected much. It could be.
However, for the time being, getting full rates out of HIPPI or SCSI are what
interests us at NASA, so we'll hew to this bias.
at least 8-). Add structure offssets for structure members, so we
know how much space we're using. Make the version in the bootinfo
structure be a u_long, so there's no implicit padding in the structure.
Add a few more pointers to the bootinfo v1 structure, which will all
be set to NULL for now.
- Allow BUGCHK and BPT instruction faults in kernel mode if DDB is enabled,
since they are used to invoke the debugger.
- Add a comment about how we'd like to invoke DDB on a trap panic condition,
in a perfect world.
pointer to boot program's bootinfo structure. If the bootinfo magic
matches, save a copy of the bootinfo structure, and use it to determine
booted kernel name, the boot flags, and the location of the kernel symbol
table. If the magic number does not match, revert to the old method
of finding this information (sans symbol table info).
- Add some additonal DDB glue.
was sent to developers, but will eventually become a man page or
something), i noticed a few in various names:
(1) _map and _alloc should take a flags argument, rather than a
'cacheable' boolean.
(2) BUS_BARRIER_* flags should be BUS_SPACE_BARRIER_*.
(3) bus_space_copy_* should be bus_space_copy_region_* for consistency
with other region ops.
Fix all of these (in a backward-compatible way, at least for now). Redefine
internal usees of those names to use the new names. Also, while at it,
clean up the copy functions (remove unnecessary variables) and make sure
that they and other functions conform to the spec.
don't assume that the names/values to be put into defines in assym.h
start with the first .ascii in the assembler file; look for the array
start symbol, instead.
* 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.
into the 'argument variables' section.
* define variables for CPP and SIZE, defaulting to cpp and size, respectively.
* kill HOSTED_C*, since it's no longer used.
* use ${SIZE} rather than using 'size' directly, so it can be overridden for
cross-builds.
* generate assym.h via assym.s and an awk script.

behaviour of splhigh() was changed. The new behaviour raised the level to
IPL_HIGH if it was lower, but left it alone if the same or higher. Apparently
the firmware transfers to NetBSD with all interrupts blocked, or something
else blocks all interrupts (including machine checks) before the code
is really started. This meant that machine checks were blocked during
device probes, leading to false device probes _and_ an unexpected (and
therefore fatal) machine check at the spl0() after autoconfiguration.
