[alsa-devel] [PATCH alsa-lib] pcm: Add the PCM state checks to plugins
by Takashi Iwai 29 Nov '16

29 Nov '16

I noticed that some plugin codes have no proper PCM state checks and it results in expected outcomes. For example, when snd_pcm_drain() is called for a dmix PCM after calling snd_pcm_drop(), it stalls unexpectedly. It's just because its drain callback doesn't expect the SND_PCM_SETUP state. We can fix such a bug in each place one by one, but a safer way would be to filter out all such cases commonly in the PCM API functions themselves. This patch adds the PCM state sanity checks to major API functions so that they return -EBADFD when called in the unexpected PCM states. As well as for the thread-safety extension, it'd be a question of the performance; again at this time, the hw PCM is considered as an exception, and it has pcm->own_state_check flag set, which means that the common PCM state checks are skipped.

[alsa-devel] [PATCH] ASoC: Intel: atom: Make some messages to debug level
by Takashi Iwai 29 Nov '16

29 Nov '16

Intel sst driver spews lots of kernel messages in INFO level; typically, it gives a kernel message at each time it allocates or frees a stream, or at each time when a stream is started or stopped. This will piles up quickly, and it's almost useless for normal users, so let's hide them to KERN_DEBUG level.

[alsa-devel] [PATCH v3] dbri: Fix compiler warning
by Tushar Dave 28 Nov '16

28 Nov '16

dbri uses 'u32' for dma handle while invoking kernel DMA APIs, instead of using dma_addr_t. This hasn't caused any 'incompatible pointer type' warning on SPARC because until now dma_addr_t is of type u32. However, recent changes in SPARC ATU (iommu) enabled 64bit DMA and therefore dma_addr_t became of type u64. This makes 'incompatible pointer type' warnings inevitable. e.g. sound/sparc/dbri.c: In function ‘snd_dbri_create’: sound/sparc/dbri.c:2538: warning: passing argument 3 of ‘dma_zalloc_coherent’ from incompatible pointer type ./include/linux/dma-mapping.h:608: note: expected ‘dma_addr_t *’ but argument is of type ‘u32 *’ For the record, dbri(sbus) driver never executes on sun4v. Therefore even though 64bit DMA is enabled on SPARC, dbri continues to use legacy iommu that guarantees DMA address is always in 32bit range. This patch resolves above compiler warning.

[alsa-devel] [PATCH] aplay: Fix to handle pause when system is suspended/Resumed
by jeeja.kp＠intel.com 28 Nov '16

28 Nov '16

From: Jeeja KP <jeeja.kp(a)intel.com> If PCM is paused and then we do system supend-resume, the stream throws error(EBADF) when stream is paused released. Check the pcm state before pause/release and if stream is suspended, call snd_pcm_resume to resume the stream.

[alsa-devel] [PATCH] alsa-lib: Protect from freeing semaphore when already in use
by sutar.mounesh＠gmail.com 28 Nov '16

28 Nov '16

From: Joshua Frkuska <joshua_frkuska(a)mentor.com> In the case of dshare, dsnoop, and dmix when a device is opened twice and fails the second time, the semaphore is completely discarded. This creates dangling semaphore data. This patch removes the possibility for the semaphore to be destroyed during a typical open failure by first checking if the shared memory can be destroyed or not. If the shared memory cannot be released it means both it and the semaphore are still in use and therefore the semaphore is just released.
