Nanobsd should make it very simple for people to create (CF-)disk images
for embedded us of FreeBSD.
Currently only works for 256MB disks. More agrressive shaving of the
build image can reduce that much further.
This may not be a generally valid configuration, but neither is relying
on the PCI clock to be stable.
The only currently known and supported hardware is the VPN14x1 from
Soekris, and since it has external clock, we fail safe(r) by using
it.
Unfortunately there is no way to probe this reliably.
Retire g_sanity() and corresponding debugflag (0x8)
Retire g_{stall,release}_events().
Under #ifdef DIAGNOSTIC:
Make g_valid_obj() an official function and have it return an an
non-zero integer which indicates the kind of object when found.
Implement G_VALID_{CLASS,GEOM,CONSUMER,PROVIDER}() macros based
on g_valid_obj().
Sprinkle calls to these macros liberally over the infrastructure.
Always check that we do not free a live object.
that I added recently:
- When a periodic timer fires, it's automatically re-armed. We must
make sure to re-arm the timer _before_ invoking any caller-supplied
defered procedure call: the DPC may choose to call KeCancelTimer(),
and re-arming the timer after the DPC un-does the effect of the
cancel.
- Fix similar issue with periodic timers in subr_ndis.c.
- When calling KeSetTimer() or KeSetTimerEx(), if the timer is
already pending, untimeout() it first before timeout()ing
it again.
- The old Atheros driver for the 5211 seems to use KeSetTimerEx()
incorrectly, or at the very least in a very strange way that
doesn't quite follow the Microsoft documentation. In one case,
it calls KeSetTimerEx() with a duetime of 0 and a period of 5000.
The Microsoft documentation says that negative duetime values
are relative to the current time and positive values are absolute.
But it doesn't say what's supposed to happen with positive values
that less than the current time, i.e. absolute values that are
in the past.
Lacking any further information, I have decided that timers with
positive duetimes that are in the past should fire right away (or
in our case, after only 1 tick). This also takes care of the other
strange usage in the Atheros driver, where the duetime is
specified as 500000 and the period is 50. I think someone may
have meant to use -500000 and misinterpreted the documentation.
- Also modified KeWaitForSingleObject() and KeWaitForMultipleObjects()
to make the same duetime adjustment, since they have the same rules
regarding timeout values.
- Cosmetic: change name of 'timeout' variable in KeWaitForSingleObject()
and KeWaitForMultipleObjects() to 'duetime' to avoid senseless
(though harmless) overlap with timeout() function name.
With these fixes, I can get the 5211 card to associate properly with
my adhoc net using driver AR5211.SYS version 2.4.1.6.

pmap. For the kernel pmap, Giant is not required. In general, for
other pmaps, Giant is required by i386's pmap_pte() implementation.
Specifically, the use of PMAP2/PADDR2 is synchronized by Giant.
Note: In principle, updates to the kernel pmap's wired count could be
lost without Giant. However, in practice, we never use the kernel
pmap's wired count. This will be resolved when pmap locking appears.
- With the above change, cpu_thread_clean() and uma_large_free() need
not acquire Giant. (The first case is simply the revival of
i386/i386/vm_machdep.c's revision 1.226 by peter.)
- Add encapmtx to protect ip_encap.c global variables (encapsulation
list).
- Unifdef #ifdef 0 pieces of encap_init() which was (and now really
is) basically a no-op.
- Lock encapmtx when walking encaptab, modifying it, comparing
entries, etc.
- Remove spl's.
Note that currently there's no facilite to make sure outstanding
use of encapsulation methods on a table entry have drained bfore
we allow a table entry to be removed. As such, it's currently the
caller's responsibility to make sure that draining takes place.
