kernel message buffer/log. Its off by default and can be switched on in the
kernel configuration on build time, be set as a variable in ddb and be set
using sysctl.
This adds the sysctl value
ddb.tee_msgbuf = 0
by default.
The functionality is especially added and aimed for developers who are not
blessed with a serial console and wish to keep all their ddb output in the
log. Specifying /l as a modifier to some selected commands will also put
the output in the log but not all commands provide one nor has the same
meaning for all commands.
This feature could in the future also be implemented as an ddb command but
that could lead to more bloat allthough maybe easier for non developpers to
use when mailing their backtraces from kernel crashes.
1) Fix small indenting issues
2) Removal of audio* at ... and midi* at ... entries and replace all them with
audio* at audiobus?
midi* at minibus?
3) Adding of USB audio/midi and IrDa entries
segment should succeed even if the segment would be marked removed; use this
to implement the Linux-compatible semantics of shmat(2)
this fixes the old Linux VMware3 graphics problem with local display,
and possibly other local Linux X clients using MIT-SHM
Use it for ST3200822A, which has a broken firmware and return an error
when accessing sector 0xfffffff with a LBA command.
Patch tested by David Brownlee.
for Linux-compatible shmat() behaviour - shmat() for the removed shared memory
segment must work from all callers, the shared memory id could be passed e.g.
to native X server via MIT-SHM
temporarily remove the functionality, the Linux-compatible semantics
will be reimplemented differently
sync with FreeBSD/OpenBSD
- Add a standard option list and make appropriate changes to the
body of the description.
- Document "-G netgroup".
- Miscellaneous grammar and mdoc fixes.
Some option resorting by yours truly.
getgrouplist(3) with *grpcnt==0, so don't _DIAGASSERT(groups != NULL).
Tweak API used between getgrouplist(3) and the back-end nsswitch methods;
move the public return value to the start of the va_list and reserve the
'void *retval' for "internal use" (e.g, errno passing or some other need).
