[alsa-devel] [PATCH] 6fire: Convert byte_rev_table uses to bitrev8
by Joe Perches 29 Oct '14

29 Oct '14

Use the inline function instead of directly indexing the array. This allows some architectures with hardware instructions for bit reversals to eliminate the array.

[alsa-devel] [PATCH v2] ASoC: rt5677: Add TDM channel mapping function
by Oder Chiou 28 Oct '14

28 Oct '14

It is for channel to slot mapping, and it is not only for 8 channels mapping, but also in 2, 4 and 6 channels mapping. If we want to use the 2 channels in the stereo2 adc path, we need to set the item "2/1/3/4" or "2/3/1/4". It also adds for stereo channel swap. It can map the sterero channels "L/R" to "R/L", "L/L" or R/R.

[alsa-devel] [PATCH v2] ASoC: Intel: Update HSW/BDW SST driver to new FW architecture
by Liam Girdwood 28 Oct '14

28 Oct '14

The following patch series updates the current upstream driver to use the new more feature rich ADSP FW architecture. The new FW arch allows for multiple instantiation of objects in dynamic memory locations. In summary :- o Modules can be created multiple times. o Modules persistent data can be allocated in any free blocks o Global scratch data can be allocated into any free blocks. o DMA can be used to load the module data. The driver now has to track and manage the new multiple module resource allocations and pass this data to FW on stream initialisations. Changes since V1 :- o Rebased on top of Vinods latest changes to remove a merge conflict. o Added mutex unlock in block error path. The series is sent as 7 patches for ease of review but should be applied as a single patch to preserve git bisect build.

[alsa-devel] [PATCH] ASoC: core: Split ops out of soc-core.c
by Mark Brown 28 Oct '14

28 Oct '14

The main ASoC source file is getting quite large and the standard ops don't really have anything to do with the rest of the file so split them out into a separate file.

[alsa-devel] [PATCH] ASoC: soc-pcm: always cancel any pending delayed stream shutdown
by Hector Palacios 28 Oct '14

28 Oct '14

After playback a shutdown is scheduled to happen within 5 seconds. If another playback takes place before the scheduled work times out, the work is cancelled, but if a recording takes place, the work will shutdown in the middle of the recording, causing problems. To reproduce the issue chain the following commands: arecord -M --duration 5 -c 2 /tmp/test.wav; aplay /tmp/test.wav; sleep 2; arecord -M --duration 5 -c 2 /tmp/test.wav; aplay /tmp/test.wav; The fist command records 5 seconds of audio. The second command plays the recorded audio. At the end of the playback a work will be scheduled to shutdown in 5 seconds, but only 2 seconds after the first playback, we run another recording. When we have recorded 3 seconds, the shutdown will occur which can cause incorrect behavior and bad recorded data. As a consequence, the last playback reproduces correct audio for the first 3 seconds and incorrect audio after that.

[alsa-devel] [PATCH v2 1/7] ASoC: Intel: Make ADSP memory block allocation more generic
by Liam Girdwood 28 Oct '14

28 Oct '14

Current block allocation is tied to block type and requestor type. Make the allocation more generic by removing the struct module parameter and adding a generic block allocator structure. Also pass in the list that the blocks have to be added too in order to remove dependence on block requestor type.

Can't be having __GFP_FS allocations with IRQs disabled. 2743 */ 2744 if (DEBUG_LOCKS_WARN_ON(irqs_disabled_flags(flags))) 2745 return; ============================================================================= By looking at 2744 line, we can get that it's because regcache_rbtree_write() would call kmalloc() with GFP flag if it couldn't find an existing block to insert nodes while this kmalloc() call is inside a spin_lock_irq_save pair, i.e. IRQs disabled. Even though this may be a bug that should be fixed, I still try to send this patch as a quick fix (work around) since it does no harm to assign default values of every registers when using regcache.

[alsa-devel] [PATCH v2] sound: pci: pcxhr: convert timeval to ktime_t
by Aya Mahfouz 28 Oct '14

28 Oct '14

This patch is concerned with migrating the time variables in the pcxhr module found in the sound driver. The changes are concerend with the y2038 problem where timeval will overflow in the year 2038. ktime_t was used instead of timeval to get the wall time. The difference is displayed now in nanoseconds instead of microseconds.
