tinymix: fix segfaults with set command
2017-01-19tinymix: fix segfaults with set commandPierre-Louis Bossart
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 Signed-off-by: Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>

Tinyalsa: Add support to poll on alsa control
2017-01-11Tinyalsa: Add support to poll on alsa controlPankaj Bharadiya
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 Change-Id: I4193809bfcdb60f4dc11e1c2ad6a07b29cfa80e9 Signed-off-by: Hardik T Shah <hardik.t.shah@intel.com> Signed-off-by: Vinod Koul <vinod.koul@intel.com> Signed-off-by: Pankaj Bharadiya <pankaj.laxminarayan.bharadiya@intel.com>

Tvl fix
2017-01-10Fix the byte control set/get methodPankaj Bharadiya
The TLV byte controls expect a TLV header as well. Check for TLV access and add TLV header size before invoking mixer API.

2017-01-10mixer: Add support for TLV RW access check apiPankaj Bharadiya
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
2016-12-28corrected (over/under)run definition in pcm.hRicardo Biehl Pasquali
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)
2016-12-24Added pcm_open_by_name()Taylor Holberton
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.
2016-12-04Added include directory in CFLAGS variableTaylor Holberton
2016-12-04Added pcm_link and pcm_unlink functionsTaylor Holberton
The link function is necessary for time sychronization between multiple PCMs.
2016-12-04added ../examples to example pathTaylor Holberton
2016-12-04Added examples subdir to 'all' and 'clean' targetsTaylor Holberton
2016-12-04Added examples for basic IOTaylor Holberton
Added an example of pcm_writei usage and an example of pcm_readi usage. Both examples use a common file called 'audio.raw'.
2016-12-04Added new ignore patternsTaylor Holberton
Added ignore patterns for files in the new 'examples' directory. The file 'audio.raw' is generated by running pcm-writei.
2016-12-02Removed asound.hTaylor Holberton
It was added because bionic didn't have a copy of the file in 2011. But, it was finally added in 2013 and update since. There is no longer a need for this file.

mixer: add ability to update control list with new controls
2016-12-02mixer: add ability to update control list with new controlsRichard Fitzgerald
New controls could appear during runtime, for example if a new firmware is downloaded to a DSP. Since ALSA drivers are not supposed to delete or renumber existing controls we can assume that any new controls will be after any controls we already know about. We can use this to enable extending our current list of controls, which is more efficient than closing the mixer session and recreating it.

2016-12-01Using frame counts in pcm_readi and pcm_writeiTaylor Holberton
pcm_readi and pcm_writei now use a frame count to specify the buffer length instead of using a byte count.
2016-12-01Replaced old calls to pcm_read and pcm_writeTaylor Holberton
The newer pcm_readi and pcm_writei functions are now being used.
2016-12-01Added pcm_readi and pcm_writei functionsTaylor Holberton
Added these functions to replace pcm_read and pcm_write, which don't return the number of frames actually transferred. On GCC-like compilers, pcm_read and pcm_write have been marked as deprecated On doxygen documentation, they have been marked as deprecated as well.
2016-12-01Added format related getters for PCMTaylor Holberton
Added functions: - pcm_get_channels - pcm_get_rate - pcm_get_format These were added since they're required for iterating samples and frames.
2016-12-01Added function, mixer_get_num_ctls_by_nameTaylor Holberton
This function is used to get the number of mixer controls by a given name. It was added for use with mixer_get_ctl_by_name_and_index so that client code can expect the last valid index to pass.
2016-12-01Merge branch 'const-correctness' into developTaylor Holberton
This merge adds the changes made to the mixer API.
2016-12-01Added mixer_get_ctl_constTaylor Holberton
This function was added to make available a mixer control accessor in a function that does not modify its value.
