| | | | | | | | | | Qualcomm's sound drivers (wrongly) set 0xffffffff as range maximum in a lot of cases, which essentially means they set that maximum value to -1 due to signed integer value overflow. Instead of patching all the kernels accordingly, drop the range check for such invalid ranges. Change-Id: I4efe0010c316f1fbfbbc004b51fbd5d40d1e1d1e
* tinyalsa: Add a board config to drop silence_size for blob compat.Christopher R. Palmer2015-11-283-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In cm-13.0, this commit was added: commit e25fe0b50ea717a9f347dcb927d396e8772e6362 Author: Maneet Singh <mmaneetsingh@nvidia.com> Date: Thu Jun 11 17:34:40 2015 -0700 pcm: add support to set silence_size Tinyalsa always set silence_size to zero. Add support to set this pcm software parameter as required. Bug: 20226809 Bug: 20300203 Change-Id: I25de43623dc04bf5a3ad4c6573bc2b8dad1eec5e that changes the size of the pcm_config structure. This is a problem for any device using older blobs that call pcm_open as their structure is now invalid. Fixing this via a prebuilt blob is not ideal because we have source built components that also use tinyalsa (e.g. the qcom audio HALs). Using a blob (either as a complete replacement or shim) would involve having code in the same address space that uses two incompatible copies of pcm_open (e.g. via a proprietary audio.primary. and a source built audio.usb.). Therefore, offer a compile option to enable this backward compatibility support. Change-Id: I4d96f2b1fe841fc19e83ddf9a4ca6c0f04bcd3f5

| | | | | | | | Many kernels don't have proper range checking on ALSA controls, which can lead to a kernel panic. Let's cut it off here. Change-Id: If3b51634f550611d1605d7203d63aca5e683e0aa

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Similar to ALSA snd_pcm_get_poll_fd, this will allow a user to wait for a sound device to have data in a poll(2) call. The hotword thread will use this to wait for a message on its socket or for audio data to become ready.

* pcm_get_htimestamp can now use CLOCK_MONOTONICGlenn Kasten2013-08-302-0/+14
| | | | | | | | | Previously the timebase was not documented. Now a new pcm_open flag can be used to specify the clock. If flag PCM_MONOTONIC is specified, then pcm_open uses SNDRV_PCM_IOCTL_TTSTAMP with parameter SNDRV_PCM_TSTAMP_TYPE_MONOTONIC to request timestamps in CLOCK_MONOTONIC.

| | | | | | | | | | | | | | | | | | | | | | | | Add a flag which can be passed to pcm_open (called PCM_NORESTART). When set on a playback stream, calls to pcm_write will not automatically attempt to restart an ALSA device in the case of an underflow. Instead, it will propagate the first EPIPE error up to the application to allow it to handle the underflow situation. Subsequent calls to pcm_write will attempt to start the pipeline.
