- Interrupt-oriented system rather than thread-oriented.
- Improve stability, quality and performance.
- Split playback and record cleanly. Improve halfduplex support.
- Many bugs are fixed including deadlocks, resource leaks, abuses, etc.
- Simplify audio filter mechanism. The encoding/channels/frequency
conversions are completely handled in the upper layer. So the hard-
ware driver only converts its hardware encoding (if necessary).
- audio_hw_if changes:
- Obsoletes query_encoding and add query_format instead.
- Obsoletes set_params and add set_format instead.
- Remove drain, setfd, mappage.
- The call sequences are changed.
- ioctl AUDIO_GETFD/SETFD, AUDIO_GETCHAN/SETCHAN are obsoleted.
- ioctl AUDIO_{QUERY,GET,SET}FORMAT are introduced.
- cleanup config attributes: au*conv and mulaw.
- All hardware drivers should follow it (I've done as much as possible).
Some file paths are changed:
- dev/audio.c -> dev/audio/audio.c (rewritten)
- dev/audiovar.h -> dev/audio/audiovar.h
- dev/audio_dai.h -> dev/audio/audio_dai.h
- dev/audio_if.h -> dev/audio/audio_if.h
- dev/audiobell.c -> dev/audio/audiobell.c
- dev/audiobellvar.h -> dev/audio/audiobellvar.h
- dev/mulaw.[ch] -> dev/audio/mulaw.[ch] + dev/audio/alaw.c
* All other bio(4) drivers either do or don't implement each command.
* This changes the returned error code, but it does not seem to matter,
as some bio(4) drivers always return ENOTTY in the default case, whilst
others always return EINVAL (e.g., both cac(4) and ciss(4) for setstate).
* XXXMRG: Stall task can run after slot is disabled when yanked.
* This hack notices that the xs has been memset() in
* xhci_disable_slot() and returns. Both xhci_reset_endpoint()
* and xhci_set_dequeue() rely upon a valid ring setup for correct
* operation, and the latter will fault, as would
* usb_transfer_complete() if it got that far.
this truly fixes yanking active ucom devices (uchcom, uplcom and
umcs all tested.) prior efforts largely worked by allowing the
stall task to run first, as a side effect to their actual work.
ok @skrll.
XXX: pullup.
* Makes it easier to do code/feature analysis by not having
extra noop code/symbols spattered around.
* Only an issue in cac(4) and ciss(4); other drivers don't do this.
* No binary changes.
the Matt Thomas rbtree:
- Include rb.c in libnbcompat, and provide a nbcompat sys/rbtree.h
header.
- Make sure libprop's source file include prop_object_impl.h before
anything else, and pull in nbtool_config.h from there.
Tested by simulating such a host system by renaming the host's
<sys/rbtree.h> out of the way (which reproduced the build failure)
and verifying that the host-tool installboot contained the rb_*
functions in its own .text segment.
with all the libpthread symbols in it.
This makes -lpthread behave like to -Wl,--whole-archive -lpthread.
This avoids a situation where threaded static binaries use some libc thread
stubs, which are racy.
Fixes PR lib/54001: call_once2_32, call_once2_static test cases failing on
amd64 since gcc7 import.
Suggested by Jonathan Wakely, thanks!
The code was wrong since rev. 1.1. This panic was found by adding KASSERT
in uvm_map.c rev. 1.351. This bug may be related to PR kern/26204.
- Use aprint_normal() for non-error message.
- Defer spa_config_load() until root is mounted.
- Restore the config path to "/etc/zfs/zpool.cache".
- Module "zfs" is type MODULE_CLASS_VFS and no longer depends on "rootvnode".
- Module "solaris" no longer depends on "mp_online".
- Fix rump component registration to not detach "/dev/zfs" if
it didn't attach it.
Solaris upstream. FreeBSD already replaced it with a glue to their
taskqueue API.
Replace it with a glue component that queues Solaris taskq requests to
threadpool jobs.
boards that use u-boot. A known board database lists boards and their
respective u-boot packages. u-boot packages are discovered at run-time
(in /usr/pkg/share/u-boot, by default). These packages contain board
database overlays that describe u-boot installation procedure that's
specific for that board.
Support this as a native tool and as a host tool. The native tool
will attempt to determine the running board type using OpenFirmware
calls. Host tool and native tool alike may also specify a board type
directly using the "-o board=xxx option" or have installboot(8) determine
the board type from a device tree blob using "-o dtb=/path/to/board.dtb".
A "-o media=xxx" option is provided for boards that have different u-boot
binaries and/or installation procedures for different media types (e.g.
SDMMC, eMMC, or USB).
This is trivial to extend to other evb* platforms that use u-boot, even if
they don't use FDT for autoconfiguration.
Deduplicate the code among ports and poll definitions of types
directly from a compiler.
This fixes miscompilation of certain programs that instruct compilers
to generate code for different types. This bug has been detected with
-fshort-wchar in EFI firmware.
Proposed and discussed on a mailing list (twice).
Itanium uses custom !ELF fallback switch, temporarily leave it as it is.

it only fixes the issue by chance (slightly delays, which
allows task to run, but there is no guarantee. real fix
is incoming for all ucom parents.
