XEN events, follow established x86/intr.c conventions - set
the 'legacy' irq value to -1, to indicate that the pic, pin
combination (&xen_pic, port) is used for registration.
In-System Design ATA protocol over Bulk-Only devices from most kernels,
leave only in i386/amd64 ALL; it's unmaintained and likely currently broken,
lack of test hardware makes it impossible to support
In re_fastputc(), set lastline to the new line, not the previous
line so it gets initialized properly. Fixes a crash in bc with
MALLOC_OPTIONS=UJ. OK deraadt@, committing on behalf of yasuoka@
Initialize "old" screen buffer lines before use; otherwise, they would
never get NUL-terminated and cause read buffer overruns.
This fixes for example segfaults in sftp(1) that could be triggered
by typing in an extremely long string (more than one line - the longer,
the likelier to crash), then hitting backspace once.
Problem reported and patch OK'ed by sthen@.
XXX: pullup-8
- Quote the opening paragraph from netbsd.org.
- Set the suggested commands in teletype.
- Give pointers in a more active voice.
- Omit trailing whitespace.
- Mention the relation of the Git mirror to the main CVS repository.
- Use a list rather than juxtaposition for the final links.
- ata_xfer's are dynamicall allocated as needed using a pool, no longer
limited to number of possible openings supported by controller; dump
and recovery paths use dedicated pre-allocated storage
- moved callouts and condvars from ata_xfer to queue or channel, so that
ata_xfer does not need special initialization
- slot allocation now done when xfer is being activated, uncoupled
from memory allocation; active slots are no longer tracked by controller
code
- channel and drive reset is done always via the atabus thread, and
now executes with channel locked the whole time
- NCQ recovery moved to shared function, and run via the thread also
- added some workarounds for buggy error recovery AHCI emulation in QEMU
and Parallels
designed to primarily fix kern/52614, but might also help with kern/47041
and kern/53183
