of a data transfer operation immediately after the data transfer
was finished, instead of waiting for the chip to interrupt us and
tell us that it was finished and had the result for us. This worked
okay for read and write since the operation would be finished very
shortly after the data transfer completed. However, with formatting,
the chip still had most of the rest of the track to do, so we ended
up timing out before the operation was finished. This fix is from
sparc64/dev/fdc.c and was tested on sparc by tnn@.
Instead, save/restore them on context switch. For 32bit processes, save/restore
the selector values only, for 64bit processes, save/restore the appropriate
MSRs. Iff the defaults have been changed.
disk volume header. On NetBSD this means RB_ASKNAME, however in SGI terms
it appears to mean 'autoboot'.
Add an appropriate kludge to keep us from doing the wrong thing.
XXX - This whole argv/env/prom parameter mess needs to be cleaned up.
into oversized volume headers:
Query ARCBIOS for OSLoadFilename and OSLoadOptions first, rather than only
using the environment variables passed since we want to go through arcemu.
Add an ugly hack to arcemu that munges the nvram 'bootfile' variable. We
need this because bootfile will point to the volume header, which then
translates into a bogus root device of 'sd0i', or similar.
device controllers, and more specifically raid controllers.
Add a new sensor type, ENVSYS_DRIVE, to report drive status. From OpenBSD.
Add bio and sysmon support to mfi(4). This allow userland to query
status for drives and logical volumes attached to a mfi(4) controller. While
there fix some debug printfs in mfi so they compile.
Add bio(4) to amd64 and i386 GENERIC.

The fact that the mapping failed is notified to the called by oring

based machine. When we do, we have to frob a few special bits on the
pcib to finish the setup that the prom didn't bother completing for us.
With this change, NetBSD finally runs on the MTX604 board.. Many thanks
to John Baker for providing remote access to the machine, and rebooting
it repeatedly for me.
avoid having to allocate space in the 'stackgap'
- which is very LWP unfriendly.
The additional code for non-emulation namei() is trivial, the reduction for
the emulations is massive.
The vnode for a processes emulation root is saved in the cwdi structure
during process exec.
If the emulation root the TRYEMULROOT flag are set, namei() will do an initial
search for absolute pathnames in the emulation root, if that fails it will
retry from the normal root.
".." at the emulation root will always go to the real root, even in the middle
of paths and when expanding symlinks.
Absolute symlinks found using absolute paths in the emulation root will be
relative to the emulation root (so /usr/lib/xxx.so -> /lib/xxx.so links
inside the emulation root don't need changing).
If the root of the emulation would be returned (for an emulation lookup), then
the real root is returned instead (matching the behaviour of emul_lookup,
but being a cheap comparison here) so that programs that scan "../.."
looking for the root dircetory don't loop forever.
The target for symbolic links is no longer mangled (it used to get the
CHECK_ALT_xxx() treatment, so could get /emul/xxx prepended).
CHECK_ALT_xxx() are no more. Most of the change is deleting them, and adding
TRYEMULROOT to the flags to NDINIT().
A lot of the emulation system call stubs could now be deleted.
+ Add pxartc and lcd(commented out) and pxaudc and pxamci (commented out).
lcd and pxamci not support yet.
+ Remove slhci.
+ Change name of expansion bords the console-{hw,st} from waysmall-{hw,st}.
Because The gumstix Co. changed the name.
vax. From OpenBSD:
Addressing mode work by Jim Uhl:
- fix PC relative byte displacement in getaddr_byte
- add support for word displacement to getaddr_byte
This allows certain libm inverse trig functions to work on systems
that lack a native polyd instruction.
