| 24-Sep-2022 |
thorpej | Remove unnecessary include of <sys/malloc.h>.
|
| 1.11 |
| 03-Apr-2021 |
isaki | Rework about the rest note in speaker(4).
- Obsolete the sc_rest callback. The rest note operation can be done by
the common spkr layer. This also fixes PR kern/56060.
This work-in-progress patch was left in my local tree for years. :(
- Improve calculations of tone and rest length.
|
| 1.10 |
| 03-Apr-2021 |
isaki | Improve SPKRDEBUG code.
- Replace wrong aprint_debug_dev() with device_printf().
By this, it no longer need to print dev_t.
- Improve some messages.
|
| 1.9 |
| 17-Feb-2021 |
isaki | branches: 1.9.2;
Attach this only if the parent device has playback capability.
|
| 1.8 |
| 21-Jun-2019 |
isaki | branches: 1.8.10;
Use hztoms() instead of incorrect calculation.
This makes spkr work on HZ=1024 like alpha.
|
| 1.7 |
| 08-May-2019 |
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

| 1.6 |
| 11-Jun-2017 |
pgoyette | branches: 1.6.4; 1.6.8; 1.6.12;
Implement xxx_rescan() and xxx_childdet() functions; these will be
needed when child device wsbell(4) becomes a separately-loadable
module.
|
| 1.5 |
| 11-Jun-2017 |
nat | Add ioctls for setting and getting the beep volume. Currently only
supported on spkr devices attached to audio.
Ok pgoyette@.
|
| 1.4 |
| 11-Jun-2017 |
nat | Remove unused code - it will reappear in a new device.
Ok pgoyette@.
|
| 1.3 |
| 06-Jan-2017 |
pgoyette | branches: 1.3.2; 1.3.6;
Implement a common spkr_detach() function and call it from the
attachment-specific detach functions. Returns EBUSY if the
device instance is busy, based on whether or not a sc->sc_inbuf
is allocated. The buffer is malloc()d at spkropen time, and is
free()d in spkrclose().
Now we can actually implement the MODULE_CMD_FINI command and
unload the driver at will.
Addresses my PR kern/51785
|
| 1.2 |
| 15-Dec-2016 |
pgoyette | Create a single combined module for spkr_pcppi and spkr_audio, and
build it for all architectures.
By doing this, we can handle pcppi, audio, or both attachments with
non-built-in modules.
XXX Still to do: the module currently cannot be unloaded, and the
XXX spkr device(s) currently cannot be detached. (Really, two
XXX sides of the same problem.)
