1: Cleanup of syscall() -- treat the arguments as an array of register_t
throughout. This saves a few casts, and generally makes seeing what's
going on easier.
2: Be a little more careful in the handling of data aborts on kernel
addresses: don't use the kernel's map unless the access was actually from
a kernel mode. This is how the arm32 data abort handler behaves.
- Use UVMHIST for debugging messages, rather than printf
- Rely on the caller of pmap_enter to tell us how to manipulate referenced/
modified bits in the kernel pmap.
[ Suggested by chs -- may need work on the rest of the kernel. ]
- Split third-stage initialisation out of pmap_create() into pmap_init2().
- Bug fix: when relocating pv_table, fix up all references to it as well.
- Bug fix: in pv_release(), if pulling up a pv_entry to the head of the
list, correct the reference from its pmap.
to CONFIG_HOOK_SET.
- merge CONFIG_HOOK_GET and CONFIG_HOOK_GETPOWER to CONFIG_HOOK_GET.
- merge CONFIG_HOOK_EVENT and CONFIG_HOOK_BUTTONEVENT to CONFIG_HOOK_ENENT.
- new CONFIG_HOOK_EVENT and CONFIG_HOOK_GET and CONFIG_HOOK_SET always have
msg argument as pointer.
- new CONFIG_HOOK_EVENT and CONFIG_HOOK_GET and CONFIG_HOOK_SET use
same event ids.
- CONFIG_HOOK_POWERCONTROL and CONFIG_HOOK_BUTTONEVENT still exist.
i shall rewite codes by using new CONFIG_HOOK_SET and CONFIG_HOOK_EVENT.
- fix math when skipping writing pages that just need a commit.
- clear the needcommit stuff and PG_RDONLY flags on pages returned for
overwrite requests as well as for normal write faults.
- bail out of nfs_write() if we get an error.
- remove a bogus attempt to clean up after failed uiomove()s.
- bring over a workaround for a lock-ordering problem from the genfs code.
- add some missing MP locking.
- in genfs_getpages() don't start read-ahead if we get an error on the
sync read, and always start read-ahead after the range of the sync read
if we do any at all.
- off-by-one error in genfs_size().
just get pmap_fault to shove them back in. Crude, but effective. Fix inspired
by Chuck Silvers.
This breaks pmap_confess, but it probably deserves to die.
XXX if you have libc after citrus locale import, please recompile libc,
and your applications that use mbstate_t (rather rare). really sorry
for the mess.
documented as to why it was added in and it breaks the ability to set the
gain on playback. A longer term fix to set these correctly should be done but
none of the drivers today are doing this and not being able to set the playback
volume otherwise is a bit silly.
are done inside of wakeup which is holding the sched lock. Printf can cause
wakeup to get called again (pty redirection of console message) which will
panic with sched lock already held.
This isn't a long term fix as not being able to printf vs. sched lock should
be cleaned up better but this avoids continual panics with lockdebug running
and an xterm -C.
only signal handler array sharable between threads
move other random signal stuff from struct proc to struct sigctx

o Avoid checking cputype when the kernel is built for one cpu variant only.
o In writeback(), don't use bcopy() to write a mere 16 bytes of 16-byte
aligned data; it's much quicker to copy it inline.
"key" and a "dlt", use a "type" (PFIL_TYPE_{AF,IFNET} for now) and
a val/ptr appropriate for that type. This allows for more future
flexibility with the pfil_hook mechanism.
Just like any ISA device, if you don't have the device at the configured IRQ,
you could lose if something else decides it wants that IRQ. wss is not
a special case.
(Lynx), written from scratch by me over a year ago, but never committed
to the tree because there was a bug I could never quite find. I have
fixed a few problems in the code, but still don't know if that bug is
quite fixed. Since I don't have access to the hardware directly, I'll
have to call for testers again.
- strip unnecessary loop to get command result status
- ack command after clearing busy bit
XXX: it still sometimes get timeout to get status(0xff50) or statistics(0xff68)
probably due to heavy load of firmware in receiving.
