as wrappers around the deprecated 4.4BSD rune functions. This paves the
way for state-dependent encodings, which the rune API does not support.
- Add __emulated_sgetrune() and __emulated_sputrune(), which are
implementations of sgetrune() and sputrune() in terms of
mbrtowc() and wcrtomb().
- Rename the old rune-wrapper mbrtowc() and wcrtomb() functions to
__emulated_mbrtowc() and __emulated_wcrtomb().
- Add __mbrtowc and __wcrtomb function pointers, which point to the
current locale's conversion functions, or the __emulated versions.
- Implement mbrtowc() and wcrtomb() as calls to these function pointers.
- Make the "NONE" encoding implement mbrtowc() and wcrtomb() directly.
All of this emulation mess will be removed, together with rune support,
in FreeBSD 6.
o change os glue API to be compatible with Linux so hal.o's can
be used on any system
o add ABI version to catch driver-HAL mismatches
o move hal version information from ah_osdep.c to binary component
o remove ath_hal_wait os glue component
o assign constant values to all enums to avoid potential compiler
incompatibilities
o add support for 3Com badged cards (PCI vendor ID)
o add support for IBM mini-pci cards (PCI device ID)
o expose MAC, PHY, and radio hardware revisions
o support for big-endian platforms
o new method to set slot time in us
o bug fix for 5211: beacon timers not setup correctly
o bug fix for 5212: don't crash when handed a 5112 radio

they were being averaged out over the time between now and when the

allows pmap_mapdev() to be used for such addresses very early during the
boot process and might provide some small savings on KVA.

This will need to be changed when state-dependent encodings are
supported, but there's no need to take the performance hit
in the meantime.
conditional evaluation is done only once in this case, and this may
not account for the fact that some conditionals would be evaluated
differently if "all" has already been run, like is the case with the
loader.help existance check in sys/boot/alpha/common/Makefile.common,
beforeinstall target. This should fix Alpha snapshot builds.
- Add an IPI based mechanism for migrating kses. This mechanism is
broken down into several components. This is intended to reduce cache
thrashing by eliminating most cases where one cpu touches another's
run queues.
- kseq_notify() appends a kse to a lockless singly linked list and
conditionally sends an IPI to the target processor. Right now this is
protected by sched_lock but at some point I'd like to get rid of the
global lock. This is why I used something more complicated than a
standard queue.
- kseq_assign() processes our list of kses that have been assigned to us
by other processors. This simply calls sched_add() for each item on the
list after clearing the new KEF_ASSIGNED flag. This flag is used to
indicate that we have been appeneded to the assigned queue but not
added to the run queue yet.
- In sched_add(), instead of adding a KSE to another processor's queue we
use kse_notify() so that we don't touch their queue. Also in sched_add(),
if KEF_ASSIGNED is already set return immediately. This can happen if
a thread is removed and readded so that the priority is recorded properly.
- In sched_rem() return immediately if KEF_ASSIGNED is set. All callers
immediately readd simply to adjust priorites etc.
- In sched_choose(), if we're running an IDLE task or the per cpu idle thread
set our cpumask bit in 'kseq_idle' so that other processors may know that
we are idle. Before this, make a single pass through the run queues of
other processors so that we may find work more immediately if it is
available.
- In sched_runnable(), don't scan each processor's run queue, they will IPI
us if they have work for us to do.
- In sched_add(), if we're adding a thread that can be migrated and we have
plenty of work to do, try to migrate the thread to an idle kseq.
- Simplify the logic in sched_prio() and take the KEF_ASSIGNED flag into
consideration.
- No longer use kseq_choose() to steal threads, it can lose it's last
argument.
- Create a new function runq_steal() which operates like runq_choose() but
skips threads based on some criteria. Currently it will not steal
PRI_ITHD threads. In the future this will be used for CPU binding.
- Create a kseq_steal() that checks each run queue with runq_steal(), use
kseq_steal() in the places where we used kseq_choose() to steal with
before.
