isaki | Merge isaki-audio2 branch, the overhaul of audio subsystem.
- 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

Tidy up a little, the way that midi attachment code works
- change midi_attach() to omit the 'parent' arg (there are
only two callers of this and it is not used)
- change midisyn_attach() to midisyn_init(), so not needing a midi_softc,
and fix the midi_pcppi driver to set hw_if and hw_hdl directly in
its midi_softc before calling midi_attach()
- add a device_t to opl_softc structure, change opl drivers to store
the device 'self' in opl_softc and fix opl_attach() to use this
opl_softc->dev field directly rather than a field in an otherwise
unused midi_softc
- remove unnecessary midi_softc from opl and cms drivers (child device
provides that)

plunky | move the pmf_device_register() for midi.c and midi_pcppi.c to midi_attach()
for symmetry, since it is removed in midi detach code
and don't need to call device_pmf_is_registered() before registering it

jmcneill | branches: 1.24.2;
Merge jmcneill-audiomp3 branch, which is derived from ad-audiomp2. From
the original ad-audiomp branch notes:
Add MP locking to the audio drivers.
Making the audio drivers MP safe is necessary before efforts
can be made to make the VM system MP safe.
The are two locks per device instance, an ISR lock and
a character device lock. The ISR lock replaces calls to
splaudio()/splx(), and will be held across calls to device
methods which were called at splaudio() before (e.g.
trigger_output). The character device lock is held across
calls to nearly all of the methods, excluding some only
used for initialization, e.g. get_locks.
Welcome to 5.99.57.

dsl | Change about 4500 of the K&R function definitions to ANSI ones.
There are still about 1600 left, but they have ',' or /* ... */
in the actual variable definitions - which my awk script doesn't handle.
There are also many that need () -> (void).
(The script does handle misordered arguments.)

chap | Now with support for the following MIDI controls -
Channel Volume
Expression
- the following heretofore unimplemented message -
Pitch Bend
- and the following registered parameters -
Pitch Bend Range
Channel Fine Tuning
Channel Coarse Tuning
Volume and Expression are handled by all synth chip drivers but pcppi
(which has a fixed volume). All of the pitch controls will be effective
(at least for new notes struck after a change) for all current synth
drivers but cms (that driver discards all the fractional pitch bits and
calculates its own frequency by a table lookup; it should be possible to
do better with knowledge of the formula behind the table, but I have
found no cms docs). If a driver provides repitchv and relevelv methods
for changing the pitch/level of a sounding voice, then changes to these
parameters will take effect in real time and not just for subsequent notes.
The effect can be heard (for repitchv) over pcppi.
Heads up: if you build with libprop earlier than 2006.05.28, you can enjoy
the exhilarating experience of seeing kernel memory stomped. ;)

chap | Bit of housecleaning.
"miditune" wasn't a good name for the pitch representation (even if it
did come from the MIDI Tuning Specification) because for too many people
a 'tune' is a little ditty, not a single pitch. Changed the name to
midipitch and added a typedef midipitch_t; renamed the associated macros
consistently.
The type and operations on it are now in <sys/midiio.h> because they could
show up in userland for manipulation of the MIDI Tuning messages that
RP-012 defines. The macro MIDIPITCH_TO_HZ18 expands in userland to
ordinary libm calls, and in-kernel to the no-floating-point version in
midisyn. A few more operations are defined in userland where libm is
available.
At the same time, made midipitch_t signed. It has the bits to spare,
and such manipulations as adding several corrections and clamping the
result will be simpler with it signed.

chap | Rototill of midisyn <-> synth driver i/f.
The DOALLOC and FREQXLATE flags are on the way out. Whether a driver wants
allocation service is deducible from whether it provides an allocv method, and
anyway none does. As for freq, they all get a miditune and can convert it
whichever way they want.
Controller handling with midictl is hooked in but few controllers watched yet.
Some macros for manipulating the miditune type are currently in midisynvar.h
but should perhaps be exported in midiio.h.
opl no longer has its own master volume state (there was no setter for it
anyway, it never changed); soon that will be handled centrally in midisyn.
Builds a kernel. Not all functionality tested yet.
|
| 1.12.14.1 |
| 07-Jun-2006 |
chap | The midisyn clients now use designated initializers so the method
structure can evolve. Only opl currently provides any methods beyond
open/close/note-on/note-off. Only cms takes a note number; the others
want a frequency. This is good because it is much easier that way to
put a common handler for tuning/pitchbend/portamento in midisyn itself.
Next up, axe most methods nobody implements. Split note-on into two
methods, one with a frequency, one with a note number, of which a driver
provides one or the other. So far all of the clients delegate voice
allocation to midisyn, so clarify that the method is getting an actual
voice number for the device and not a MIDI channel. If a device that can
do its own allocation is later to be supported, let appropriate different
methods be added then.

Follow the merge of pmap.c on i386 and amd64 and move
pmap_init_tmp_pgtbl into arch/x86/x86/pmap.c. Modify the ACPI wakeup
code to restore CR4 before jumping back into kernel space as the large
