available. The per-cpu variable ss_tpr has been replaced by ss_eflags.
This reduced the number of interrupts sent to the wrong CPU, due to
the cpu having the global lock being inside a critical region.
Remove some unneeded manipulation of tpr register in mplock.s.
Adjust code in mplock.s to be aware of variables on the stack being
destroyed by MPgetlock if GRAB_LOPRIO is defined.
update of cpu usage as shown by top when one process is cpu bound
(no system calls) while the system is otherwise idle (except for top).
Don't attempt to switch to the BSP in boot(). If the system was idle when
an interrupt caused a panic, this won't work. Instead, switch to the BSP
in cpu_reset.
Remove some spurious forward_statclock/forward_hardclock warnings.
Don't forget to clear the inode hash lock before returning from ext2_vget()
after getnewvnode() fails. Obtained from: rev.1.24 of ffs_vfsops.c (the
original patch for the getnewvnode() race). Forgotten in: rev.1.4 here.
Removed a duplicate comment. Duplicated in: rev.1.4 here.
Fixed the MALLOC() vs getnewvnode() race in ext2_vget(). Obtained from:
rev.1.39 of ffs_vfsops.c.
Windows 95 after rebooting FreeBSD without power off. In PC-98
system, reboot mode is set via I/O port 0x37 in cpu_reset(), and
accessing of this port is the reason of the problem. To avnoid the
fault, current status of reboot mode should be checked before
accessing the I/O port.
that local APIC should be disabled in UP system. However, some of old
BIOS does not disable local APIC, and virtual wire mode through local
APIC may cause int 15.
submitted ioctl to clear the video buffer
prior to starting video capture
Amancio : clean up yuv12 so that it does not
affect rgb capture. Basically, fxtv after
capturing in yuv12 mode , switching to rgb
would cause the video capture to be too bright.
1.32 disable inverse gamma function for rgb and yuv
capture. fixed meteor brightness ioctl it now
converts the brightness value from unsigned to
signed.
1.33 added sysctl: hw.bt848.tuner, hw.bt848.reverse_mute,
hw.bt848.card
card takes a value from 0 to bt848_max_card
tuner takes a value from 0 to bt848_max_tuner
reverse_mute : 0 no effect, 1 reverse tuner
mute function some tuners are wired reversed :(
Define a parameter which indicates the maximum number of sockets in a
system, and use this to size the zone allocators used for sockets and
for certain PCBs.
Convert PF_LOCAL PCB structures to be type-stable and add a version number.
Define an external format for infomation about socket structures and use
it in several places.
Define a mechanism to get all PF_LOCAL and PF_INET PCB lists through
sysctl(3) without blocking network interrupts for an unreasonable
length of time. This probably still has some bugs and/or race
conditions, but it seems to work well enough on my machines.
It is now possible for `netstat' to get almost all of its information
via the sysctl(3) interface rather than reading kmem (changes to follow).
signanosleep() did not deal with signal masks properly. This change was
based on a discussion with bde some time ago (at least 6 months or more).
signanosleep() should probably go away since it was never really used for
more than a few weeks and doesn't appear in released code. It should
probably be killed before somebody uses it and it becomes a gratuitous
nonstandard feature.
