platforms except ia64 and use Int_Open_Disk() in open_ia64_disk.c
on ia64. We need to know more than GEOM can provide us so we're
forced to read from the disk. Move uuid_type() to open_ia64_disk.c
and remove all references on non-ia64.
o Pass the GEOM conftxt to Int_Open_Disk() so that only Open_Disk()
needs to know about GEOM and libdisk can more easily be used with
media not handled by GEOM.
o Create an ia64 specific definiton of struct disk on ia64, because
we don't need/have most of the fields other platforms need and
other fields not applicable on platforms other than ia64.
o Do not compile change.c on ia64. It's too PC specific.
o In Fixup_Names() in create_chunk.c, try all partition numbers
that are valid for the GPT disk. We have the total number of
partitions that can be allocated in the disk structure on ia64.
Also, use the GPT partition naming if we're creating one under
a chunk of type "whole". It's a GPT partition in that case.
o In Create_Chunk(), compile-out the PC specific code on ia64 that
checks BIOS geometry restrictions.
o In Debug_Disk() in disk.c, dump the ia64 specific fields.
o Save the partition index in the chunk on ia64 so that we can
preserve it when we write the data back to disk. This avoids that
partitions get moved around or swapped after installing FreeBSD,
which may render a disk unusable.
Cyl_Aligned(), Prev_Cyl_Aligned() and Next_Cyl_Aligned() into
tautologies on ia64. GPT removes all notion of tracks, heads and
sectors per track, so there are no alignment considerations.
previously only considered the send sequence space. Unfortunately,
some OSes (windows) still use a random positive increments scheme for
their syn-ack ISNs, so I must consider receive sequence space as well.
The value of 250000 bytes / second for Microsoft's ISN rate of increase
was determined by testing with an XP machine.
doesn't have any meaning and only results in lines longer than 80
characters.
o In Delete_Chunk2(), also look for chunks of type "part" under
chunks of type "whole" on ia64. They're not only under chunks of
type "freebsd" there.
wasn't curthread, i.e. when we receive a thread pointer to use
as a function argument. Use VOP_UNLOCK/vrele in these cases.
The only case there td != curthread known at the moment is
boot() calling sync with thread0 pointer.
This fixes the panic on shutdown people have reported.
slice assignment. Add a comment describing what it does.
- Remove a stale XXX comment, the nice should not impact the interactivity,
nice adjustments only effect non-interactive tasks in ULE.
- Don't allow nice -20 tasks to totally starve nice 0 tasks. Give them at
least SCHED_SLICE_MIN ticks. We still allow nice 0 tasks to starve nice
+20 tasks as intended.
- SCHED_PRI_NRESV does not have the off by one error in PRIO_TOTAL so we
do not have to account for it in the few places that we use it.

0 and SCHED_SLP_RUN_MAX * 2. This allows us to simplify the algorithm
quite a bit. Before, it dealt with arbitrary values which required us
to do nasty integer division tricks that didn't quite work out correctly.
- Chnage sched_wakeup() to detect conditions where the slp+runtime could
exceed SCHED_SLP_RUN_MAX * 2. This can happen if we go to sleep for
longer than 6 seconds. In this case, we'll just clear the runtime and
set the sleep time to the max.
- Define a new function, sched_interact_fork() which updates the slp+runtime
of a newly forked thread. We want to limit the amount of history retained
from the parent so that we learn the child's behavior quickly. We don't,
however want to decay it to nothing. Previously, we would simply divide
each parameter by 100 whenever we forked. After a few forks the values
would reach 0 and tasks would not be considered interactive.
- Add another KTR entry, cleanup some existing entries.
- Remove a useless sched_interact_update() from sched_priority(). This is
already done by the callers that require it.
o Also allow swap and filesystem partitions outside a freebsd slice.
This is typically the case for GPT.
o Allow chunks of type "whole" to be displayed at the top. This is
to allow a GPT disk to be labeled. We need a slice out of which we
can make partitions, but a GPT disk doesn't have slices. For GPT
disks a chunk of type "whole" can then be used as a placeholder.
destination objects are locked on entry and exit. Add comments to
the callers noting that the locks can be released by swap_pager_copy().
- Remove several instances of GIANT_REQUIRED.
depending on namespace pollution in <sys/stat.h> for the declarations of
struct timeval and utimes().
Fixed some style bugs in rev.1.30 and some nearby style bugs (mainly
unsorting and missing or extra blank lines).
Removed a wrong comment that was obtained from NetBSD in rev.1.14. It said
that chflags() reset the times that were set "above" by utimes(), but
utimes wasn't "above" in FreeBSD until rev.1.30, and chflags() does't
actually reset the times.
we will generate for a given ip/port tuple has advanced far enough
for the time_wait socket in question to be safely recycled.
- Have in_pcblookup_local use tcp_twrecycleable to determine if
time_Wait sockets which are hogging local ports can be safely
freed.
This change preserves proper TIME_WAIT behavior under normal
circumstances while allowing for safe and fast recycling whenever
ephemeral port space is scarce.
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
where MB/s and tps statistics would always be zero, presumably because
they were being averaged out over the time between now and when the
system booted instead of a few seconds.
