[alsa-devel] [PATCH v2 1/2] ARM: imx: clk: Split SSI clock into 'ipg' and 'per'
by Fabio Estevam 09 Oct '12

09 Oct '12

Currently imx ssi driver has been using only the ipg clock as only slave mode is supported. For mx27 it is necessay to provide both 'ipg' and 'per' clocks in order to get ssi functional. This issue was found on mx27 by unselecting the mmc driver from the kernel ,which resulted on a system that could not play audio. When the mmc driver is selected the required 'per2' clock is provided and it allows the ssi to work. Add the required 'per' clock to the mx27 ssi and a dummy one for the other SoCs.

[alsa-devel] [PATCH 1/2] ARM: imx: clk: Split SSI clock into 'ipg' and 'per'
by Fabio Estevam 08 Oct '12

08 Oct '12

Currently imx ssi driver has been using only the ipg clock as only slave mode is supported. For mx27 it is necessay to provide both 'ipg' and 'per' clocks in order to get ssi functional. This issue was found on mx27 by unselecting the mmc driver from the kernel ,which resulted on a system that could not play audio. When the mmc driver is selected the required 'per2' clock is provided and it allows the ssi to work. Add the required 'per' clock to the mx27 ssi and a dummy one for the other SoCs.

[alsa-devel] [PATCH] pcm: support for audio timestamps
by Pierre-Louis Bossart 08 Oct '12

08 Oct '12

add new snd_pcm_status_get_audio_htstamp() routine to query the audio timestamps provided by the kernel. This change provides applications with better ways to track elapsed time. Before this patch, applications would subtract queued samples (delay) from written samples, resulting in a 1-2 sample error. Also add snd_pcm_hw_params_supports_audio_wallclock_ts() to query what the hardware supports. TODO: check protocol compatibility?

[alsa-devel] [3.6-rc7] switcheroo race with Intel HDA...
by Daniel J Blueman 08 Oct '12

08 Oct '12

On my Macbook with a discrete Nvidia GPU, there is a race between selecting the integrated GPU and putting the discrete GPU into D3 [1], reliably causing a kernel oops [2]. Introducing a delay of ~1s between the calls prevents this. When the second 'OFF' write path executes, it looks like struct azx at card->private_data hasn't yet been allocated yet [3], so there is likely some locking missing. I'm happy to perform further testing and debug of course...
