[alsa-devel] FW: Further goals of thread-safe PCM API
by Wischer, Timo (ADITG/SW1) 27 Apr '17

27 Apr '17

Hi everyone, I am wondering about the implementation of the new thread-safety feature [1]. There are so many issues with deadlocks (e.g. [3]) which were already solved but also which are not yet solved. Why do you not using a recursive mutex to avoid most of this deadlocks? Using PTHREAD_MUTEX_RECURSIVE as the pthread attribute [2]. What is the preferred solution for external ALSA plugins which are using the external IO plugin SDK to prevent such deadlocks? For example I have one plugin which calls snd_pcm_avail() in the ext IO plug start callback. This ends up in a deadlock. #0 0x0000003f44e0feec in __lll_lock_wait () from /lib64/libpthread.so.0 #1 0x0000003f44e09b15 in pthread_mutex_lock () from /lib64/libpthread.so.0 #2 0x00007ffff7d3c8b4 in snd_pcm_lock (pcm=0x623150) at ../../../alsa-lib-1.1.2/src/pcm/pcm_local.h:1101 #3 snd_pcm_avail (pcm=0x623150) at ../../../alsa-lib-1.1.2/src/pcm/pcm.c:2762 #4 0x00007ffff7ae1e03 in ??

Or is there a better solution available? >From my point of view the usage of a recursive mutex would be the best and most stable solution.

[alsa-devel] [PATCH][resend] topology: Allow a data section to contain multiple tuples objects
by fuweix.tang＠intel.com 27 Apr '17

27 Apr '17

From: Mengdong Lin <mengdong.lin(a)linux.intel.com> It's easy to use a vendor tuples object to define a C structure instance as vendor specific parameter for kernel drivers. And sometimes the kernel drivers may want a group of structures. So this patch will allow user to define multiple vendor tuples objects in a data section, to avoid defining multiple data sections and each data section only has 1 vendor tuples object. There is no ABI change in this patch.

[alsa-devel] [PATCH 00/11] drm/i915: LPE audio runtime PM and multipipe
by ville.syrjala＠linux.intel.com 26 Apr '17

26 Apr '17

From: Ville Syrjälä <ville.syrjala(a)linux.intel.com> I was wondering why my VLV no longer runtime suspended, and after some thinking I decided it had to be the LPE audio preventing it. Turns out I was right, so here's my attempt at fixing it. And while looking at the code I couldn't help but notice that it couldn't actually handle multiple pipes playing back audio at the same time. And even having multiple displays active even if only one was playing audio was probably a recipe for failure. So I tried to fix that by registering a separate PCM device for each pipe. Note that the patch subjects may not reflect the subsystem very well since most of these straddle the border between drm and alsa. I think I just slapped on drm/i915 to most where there was no clear winner.

[alsa-devel] [PATCH 0/6] ASoC: Intel: Skylake: Add loadable module support for
by Subhransu S. Prusty 26 Apr '17

26 Apr '17

Module loading (which are not part of base firmware) is different for kbl platform compared to skl or bxtn. In kabylake library manifest contains the module information, so load the library to get the module information. As a pre-work, common code which can be used for kabylake are moved to helper and arguments to few functions are modified to support module load for kabylake.

[alsa-devel] [PATCH v2 0/6] ASoC: Intel: Skylake: Add loadable module support for Kabylake
by Subhransu S. Prusty 26 Apr '17

26 Apr '17

KBL module load is a bit different than rest as Library manifest containing module information is required to be loaded first before loading module. So common changes are moved to helpers and arguments are modified as a pre-work for adding module loading support. Also, separate dsp_fw_ops is registered and load library for kabylake is added to use code loader dma for library and module load. changes in v2: - Few minor fixes in comments - Fixed the cover letter subject G Kranthi (2): ASoC: Intel: Skylake: Move sst common initialization to a helper function ASoC: Intel: Skylake: Modify arguments to reuse module transfer function Sodhi, VunnyX (1): ASoC: Intel: Skylake: Add loadable module support on KBL platform Subhransu S.

From: Markus Elfring <elfring(a)users.sourceforge.net> Date: Wed, 26 Apr 2017 12:26:06 +0200 A multiplication for the size determination of a memory allocation indicated that an array data structure should be processed. Thus use the corresponding function "devm_kcalloc". This issue was detected by using the Coccinelle software.

[alsa-devel] ALSA / Soundcard latency
by Feilmeier Daniel (Ask De) 26 Apr '17

26 Apr '17

Hello, My company is a supplier of car manufacturers. We develop and produce digital audio amplifiers. We would like to build our test setup for echo order cancelation routines for our audio amplifiers with a real- time Linux and ALSA. We have very strong requirements regarding the maximum latency from audio input via line in to audio output. We would like to achieve a maximum latency < 1ms. The alsaloop example mentions a latency of 1 ms which is on our test setup with the latest rt kernel from This Mächler not working due to broken pipe errors. Is 1 ms feasible with a standard PC ? Currently we still don´t know what the lowest possible latency using ALSA is. We tried different soundcards and found out that they have an internal FIFO, which seems to be one of the limiting factors. The min. latency we can achieve is currently 5,6 ms, but this is still to high. Is there any possibility to switch this FIFO off via ALSA ? Is it possible at all to achieve such low latency values ? Kind regards, ___________________________________________________________________________________ Feilmeier Daniel R&D Software Electronics Tel.: +49-9962-2003-629 Fax.: +49-9962-2003-79 E-Mail: FeilmeierD(a)askgroup.de<mailto:FeilmeierD@askgroup.de> ASK Industries GmbH Hauptstrasse 73 D-94559 Niederwinkling HRG Straubing HRB 10703 Geschaeftsfuehrer: Ruggero Marchetti Franz Maier Juergen Pledl ___________________________________________________________________________________
