[alsa-devel] [PATCH V2] PCM: snd_pcm_xxxx_drain() maybe blocked after suspend and resume
by Shengjiu Wang 12 Jun '15

12 Jun '15

After suspend and resume, the alsa driver is stopped. But if alsa-lib run into snd_pcm_xxxx_drain(), it need to wait avail >= pcm->stop_threshold, otherwise, it will not exit the loop, so finally it is blocked at poll() of snd_pcm_wait_nocheck(pcm, -1). This patch is to add state check after snd_pcm_wait_nocheck(pcm, -1), if the state is SND_PCM_STATE_SUSPENDED, then return error. Signed-off-by: Shengjiu Wang <shengjiu.wang(a)freescale.com> --- changes in v2: - Add state check in beginning of drain() - Add fix for pcm_dshare() - Mov the state check to the place that is after snd_pcm_direct_clear_timer_queue(dmix). That the suspend may happen just before calling snd_pcm_direct_clear_timer_queue(dmix), which will force the next poll to wait.
