[alsa-devel] [PATCH 0/5] Let's kill BUG*()
by Takashi Iwai 05 Nov '13

05 Nov '13

Hi, this is a series of trivial patches to kill BUG() and BUG_ON() in sound/* (except for ASoC codes, which will follow later). Basically BUG() and BUG_ON() are usless for drivers like sound drivers, because they stop the whole operation intentionally by calling panic(). In this patch series, they are replaced with WARN_ON(), snd_BUG() or something else more soft ones. [PATCH 1/5] ALSA: ctxfi: Use WARN_ON() instead of BUG_ON() [PATCH 2/5] ALSA: ps3: Use WARN_ON() instead of BUG_ON() [PATCH 3/5] ALSA: sparc/cs4231: Use WARN_ON() instead of BUG_ON() [PATCH 4/5] ALSA: mips/ad1843: Use WARN_ON() instead of BUG_ON() [PATCH 5/5] ALSA: pxa2xx: Replace BUG() with snd_BUG() Takashi

[alsa-devel] snd-hda-intel with ALC880 on a ASUS W5A since patch 67b6ec3196da235317ff1b9474f17379b78f3294
by nb 05 Nov '13

05 Nov '13

Hi, Going from kernel 3.2 to kernel 3.10, I met a sound problem. It completely stopped. Neither speakers nor headphones (jack) work. Following Jonathan Woith advice, I have narrowed down the kernel version which caused the problem using a kernel git bisect (it took me 3 days long!). The patch causing the problem is: 67b6ec3196da235317ff1b9474f17379b78f3294 ALSA: hda/realtek - Drop all ALC880 static quirks I hope I haven't made a mistake. 29e3fdcc84e5da04cb7e6a36fee0a772c91d3b28 seems to be good and 67b6ec3196da235317ff1b9474f17379b78f3294 seems to be bad. You can find attached: - alsa-info output of non working kernel (3.11) - alsa-info output of working kernel (3.2) Can you please help me? I have tried at alsa-users forum but with no success. If you need more informations, please let me know. Regards nb

[alsa-devel] Microphones not working on Apple macbook Air 1, 1 (Early 2008) under 3.2.0-55-generic-pae Linux
by Nicolo' 05 Nov '13

05 Nov '13

Hello List, from time to time I spend time on this problem. (Of course, it is not related to muting or capturing in alsamixer, or pulseaudio stuff, since that was already tried.) I can't get the mics to work, neither the internal one nor the external; note that the same jack works both for HP and ext MIC, I think it's called TRRS, and it's the same as the one used e.g. on iphones. I tried also with more recent kernels, and playing with hda-jack-retask, but with no success up to now. alsa script result at https://www.dropbox.com/l/HHLkdCW4Shcak8gq2rBSY8 A curious fact, I found this alsa script result http://www.alsa-project.org/db/?f=3ca8243c0626844f0264a3faad0aa72018bc14f4f… a guy running Arch on the same machine, where actually some Mic appears in codec#0: do you think it is relevant? Thanks and best, Nicolo'

[alsa-devel] async between dmaengine_pcm_dma_complete and snd_pcm_release
by Qiao Zhou 05 Nov '13

05 Nov '13

Hi Mark, Liam, Jaroslav, Takashi I met an issue in which kernel panic appears in dmaengine_pcm_dma_complete function on a quad-core system. The dmaengine_pcm_dma_complete is running core0, while snd_pcm_release has already been executed on core1, due to in low memory stress oom killer kills the audio thread to release some memory. snd_pcm_release frees the runtime parameters, and runtime is used in dmaengine_pcm_dma_complete, which is a callback from tasklet in dmaengine. In current audio driver, we can't promise that dmaengine_pcm_dma_complete is not executed after snd_pcm_release on multi cores. Maybe we should add some protection. Do you have any suggestion? I have tried to apply below workaround, which can fix the panic, but I'm not confident it's proper. Need your comment and better suggestion. From d568a88e8f66ee21d44324bdfb48d2a3106cf0d1 Mon Sep 17 00:00:00 2001 From: Qiao Zhou <zhouqiao(a)marvell.com> Date: Wed, 9 Oct 2013 15:24:29 +0800 Subject: [PATCH] ASoC: soc-dmaengine: add mutex to protect runtime param under SMP arch, the dmaengine_pcm_dma_complete callback has the chance to run on one cpu while at the same time, the substream is released on another cpu. thus it may access param which is already freed. we need to add mutes to protect such access, and check PCM availability before using it.
