[alsa-devel] [PATCH] ASoC: rockchip: Add support rt5514 dsp summy dailink
by Xing Zheng 19 Aug '16

19 Aug '16

This patch can attach automaticlly rt5514 spi DAI with driver name "rt5514" in the snd_soc_find_dai process. Turn this feature on, we can enable the voice wake up via rt5514 dsp for RK3399 Gru Boards.

[alsa-devel] Use of copy_to_user in fireworks_hwdep.c while holding a spin_lock
by Vaishali Thakkar 19 Aug '16

19 Aug '16

Hello, I was wondering about the call to copy_to_user in function hwdep_read_locked and hwdep_read_resp_buf for driver sound/firewire/fireworks/fireworks_hwdep.c. The function hwdep_read calls both of these functions while holding a spinlock[1], which is not normally allowed due to the possibility of a deadlock. This seems to be coming from the commit 555e8a8f7f149544eb7d4aa3a6420bc4c3055638 while adding a command/response functionality into hwdep interface. Is there some reason that I am overlooking, why it is OK in this case? Is there some code in the same file which ensures that page fault will not occur when we are calling these functions while holding a spin_lock_irq? The same issue is there with the driver sound/firewire/tascam/tascam-hwdep.c for obvious reasons. Coccinelle script is used to detect this issue. Thank you.

[alsa-devel] [PATCH 0/3] line6 locking and segfault fixes
by Andrej Krutak 19 Aug '16

19 Aug '16

These are already seen patches fixing a few locking issues, now split out of the POD-X3 patchset. In addition, pod sysfs attributes touched something else than they thought, causing segfaults - fixed it (tested with the same code in podhd)... Andrej Krutak (3): ALSA: line6: Remove double line6_pcm_release() after failed acquire. ALSA: line6: Give up on the lock while URBs are released.

[alsa-devel] [PATCH 00/17] Baytrail audio fixes
by Pierre-Louis Bossart 18 Aug '16

18 Aug '16

This second set of patches solves problems with Baytrail-CR, specifically the auto-detection of IRQ index and SSP0 routing. These patches enable sound on the Asus T100TAF with the support of the MCLK handled by the clock framework (Credits to Irina Tirdea) If you prefer git access, the patches are available at https://github.com/plbossart/sound/commits/t100taf-6 The corresponding UCM file is at https://github.com/plbossart/UCM/commits/t100-test Thanks to Luka Karinja and Antonio Ospite for early tests and suggestions, as well as Liam Girdwood and Vinod Koul for internal code reviews. Additional fixes for UCM files will be coming soon to support mono speakers, IN3 input and other fixes.

[alsa-devel] [PATCH for 4.8] Revert "ASoC: omap-mcpdm: Add support for pdmclk clock handling"
by Peter Ujfalusi 18 Aug '16

18 Aug '16

This reverts commit 65aca64d05b5eaa5ce15e18b458a8d338ddbd478. The patches for twl6040 MFD and clk missed the merge window and causing the McPDM driver to never probe since it is put back to the deferred list because the missing drivers. Signed-off-by: Peter Ujfalusi <peter.ujfalusi(a)ti.com> --- Mark, OMAP4/5 audio regressed in 4.8 due to the hack that the twl6040 MFD and clk driver changes were not take in time. The only clean solution I can think is to revert the pdmclk clock handling from the McPDM driver for now.
