Replace old style Android.mk with new Android.bp
|
|
Create a new Android.bp file used by Android Oreo. There are
dependencies on tinyalsa from other components in Oreo that
use the new build system and these break if tinyalsa is using
the older Android.mk build system.
Oreo still picks up and tries to build the Android.mk found in
the jni directory and this leads to a build conflict so it has
been deleted.

interval.h: add missing header
|
|
The ssize_t type requires the unistd.h header. This fixes build with musl
libc:
In file included from ../include/tinyalsa/limits.h:32:0,
from limits.c:1:
../include/tinyalsa/interval.h:38:2: error: unknown type name 'ssize_t'
ssize_t max;

Fix to pass num_frames to pcm_writei
|
|
pcm_writei expects size of data in frames, whereas currently size
is passed as number of bytes. So convert number of bytes to frames
for argument to pcm_writei.

tinymix: fix segfaults with set command
|
|
The arguments passed after the set command are not handled properly,
leading to segfaults or inability to set controls
Example with control 0 which is Headset Volume on my NUC:
before fix
$ ./tinymix set 0
Segmentation fault
$ ./tinymix set 0 10
Segmentation fault
$ ./tinymix set 0 10 20
Error: 3 values given, but control only takes 2
After correction
$ ./tinymix set 0
no value(s) specified
$ ./tinymix set 0 10
$ ./tinymix set 0 10 10
$ ./tinymix set 0 10 10 10
Error: 3 values given, but control only takes 2

Tinyalsa: Add support to poll on alsa control
|
|
ALSA controls support polling on the kcontrols, this is used in HD-A for
jack notifcation. In tinyalsa we can use this for notfication from sound
card for any events detected by DSP

Tvl fix
|
|
The TLV byte controls expect a TLV header as well. Check for TLV
access and add TLV header size before invoking mixer API.

Tinyalsa doesn't expose an api to check TLV RW access
Add mixer_ctl_is_access_tlv_rw().
This api will get used by tinymix and audio HALs for checking TLV RW
access before managing the byte related mixer controls.

pcm.h -- (over/under)run definition
|
|
overrun is in capture and underrun is in playback.
Look:
'+' has data / '-' hasn't data
overrun (capture):
You should have
read until here
v
|+++++++|++ <- buffer over(run/flow)
underrun (playback):
You should have
written until here
v
|+++++++|-- <- buffer under(run/flow)
|
|
This function parses a PCM name similar to the ALSA library.
This is done so that the differences between alsa-lib and tinyalsa
are a little more transparent to the user.
|
|
|
|
The link function is necessary for time sychronization between multiple PCMs.
|
|
|
|
|
|
Added an example of pcm_writei usage and an example of pcm_readi
usage. Both examples use a common file called 'audio.raw'.
