- Move tagged queueing control from ADA to ATA XPT. It allows to control
device command queue length correctly. First step to support < 32 tags.
- Limit queue for non-tagged devices by 2 slots for ahci(4) and siis(4).
- Implement quirk matching for ATA devices.
- Move xpt_schedule_dev_sendq() from header to source file.
- Move delayed queue shrinking to the more expected place - element freeing.
- Remove some SCSIsms in ATA.
These keys have different sequences when using cursorkeys, while insert
and delete stay the same. If they are placed like this, libteken will
return NULL instead of a proper sequence for these characters.
This will make it more easy for people to experiment with TERM=xterm.
Instead of echoing these strange escape sequences, I can just instruct
them to run `vidcontrol -T xterm'.
xterm and cons25 have some incompatibilities when it comes to escape
sequences for special keys, such as F1 to F12, home, end, etc. Add a new
te_fkeystr() that can be used to override the strings.
scterm-sck won't do anything with this, but scterm-teken will use
teken_get_sequences() to obtain the proper sequence.
I thought this only had to be done when in origin mode, to ensure that
the cursor is not placed outside the origin, but it seems this is also
done when not in origin mode.
This fixes some artifacts when pressing ^L while running irssi in tmux.
(Almost) nobody noticed this, because cons25 doesn't have scrolling
regions.
function that immediately reacquires the lock. Also removes recursive
locking.
- Use the statistics timer to drive the transmit watchdog instead of using
if_watchdog and if_timer.

when they did their thing i.e. enabling SX mode
and then trying to load in. Since we are o32 this
is all un-needed. So I have re-structured the code
to work without doing this special set of code.
Packets now flow in and out.. however for some
reason dhcp/bootp response comes in and the kernel
does not proceed. Not sure if we have a UDP checksum error
or ?? The packets look all there by comparing wireshark
and the first 64 bytes of the TX and RX packets.
dvp == vp. Rename syscall does not check for the case, and at least
ufs_rename() cannot deal with it. POSIX explicitely requires that both
rename(2) and rmdir(2) return EINVAL when any of the pathes end in "/.".
Detect the slashdot lookup for RENAME or REMOVE in lookup(), and return
EINVAL.

sure that a signal was delivered to the thread before returning from
syscall. Signal delivery puts new return frame on the user stack, and
modifies trap frame to enter signal handler. As a consequence, syscall
return code sets EINTR as error return for signal frame, instead of the
syscall return.
Also, for ia64, due to different registers layout for those two kind of
frames, usermode sigsegfaulted when returned from signal handler.
Use newly-introduced cpu_set_syscall_retval(9) to set syscall result,
and return EJUSTRETURN from kern_sigsuspend() to prevent syscall return
code from modifying this frame [1].
Another issue is that pending SIGCONT might be cancelled by SIGSTOP,
causing postsig() not to deliver any catched signal [2]. Modify
postsig() to return 1 if signal was posted, and 0 otherwise, and use
this in the kern_sigsuspend loop.

offer to install an SMP kernel. The way this worked was: on supported
platforms, code to read ACPI tables and BIOS MP tables was compiled into
sysinstall, and if an SMP kernel config was present in the source tree when
sysinstall was built, code that called it was also compiled. Since we
haven't had SMP kernel configs in years, the latter was never compiled and
the former never ran.
This only removes dead and unreachable code; it does *not* remove the NCpus
variable, nor the code that sets it to 1, nor the code that asks the user to
select a kernel from a list.

functions are selfcontained (ie. they touch only isa_dma.c static variables
and hardware) so a private lock is sufficient to prevent races. This changes
only i386/amd64 while there are also isa_dma functions for ia64/sparc64.
Sparc64 are ones empty stubs and ia64 ones are unused as ia64 does not
have isa (says marcel).
This patch removes explicit locking of Giant from a few drivers (there
are some that requires this but lack ones - this patch fixes this) and
also removes the need for implicit locking of Giant from attach routines
where it's provided by newbus.

is free to forward packets via whatever interface it wants, so checking
capabilities of the interface passed from ip_output (fetched from the routing
table) serves no purpose.
