[alsa-devel] [PATCH] drm: mediatek: fix prototypes after API change
by Arnd Bergmann 02 Jul '16

The newly added mediatek HDMI driver clashes with an API change for struct hdmi_codec_ops, causing an 'allmodconfig' build to fail: drivers/gpu/drm/mediatek/mtk_hdmi.c:1653:15: error: initialization from incompatible pointer type [-Werror=incompatible-pointer-types] drivers/gpu/drm/mediatek/mtk_hdmi.c:1654:19: error: initialization from incompatible pointer type [-Werror=incompatible-pointer-types] drivers/gpu/drm/mediatek/mtk_hdmi.c:1655:20: error: initialization from incompatible pointer type [-Werror=incompatible-pointer-types] drivers/gpu/drm/mediatek/mtk_hdmi.c:1656:18: error: initialization from incompatible pointer type [-Werror=incompatible-pointer-types] drivers/gpu/drm/mediatek/mtk_hdmi.c:1657:13: error: initialization from incompatible pointer type [-Werror=incompatible-pointer-types] This changes the API accordingly for the mediatek driver. Signed-off-by: Arnd Bergmann <arnd(a)arndb.de> Fixes: 8f83f26891e1 ("drm/mediatek: Add HDMI support") Fixes: efc9194bcff8 ("ASoC: hdmi-codec: callback function will be called with private data") --- The new driver is currently part of Dave Airlie's drm-next tree, while the API change is in Mark Brown's asoc-next tree, so my fix has to be done on top of both. I can see two ways out of this: a) Stephen Rothwell could add my fixup on top of linux-next as a merge fix, and the fix gets sent to Linus Torvalds along with the second of the two branches b) efc9194bcff8 gets merged into drm-next along with my change in the merge commit.

[alsa-devel] Assertion failure in alsa-lib crashing applications (snd_pcm_area_copy: Assertion `dst < src || dst >= src + bytes' failed)
by Baptiste Jonglez 01 Jul '16

01 Jul '16

Hi, When using Ring [1], an audio-video application, it sometimes crashes because of an assertion in libasound.so: pcm.c:2758: snd_pcm_area_copy: Assertion `dst < src || dst >= src + bytes' failed. The complete upstream bug report is at [2]. The (not-so-useful) stack trace is the following: #0 0x00007fc356e462a8 raise (libc.so.6) #1 0x00007fc356e4772a abort (libc.so.6) #2 0x00007fc356e3f1b7 __assert_fail_base (libc.so.6) #3 0x00007fc356e3f262 __assert_fail (libc.so.6) #4 0x00007fc35ba65c84 snd_pcm_area_copy (libasound.so.2) #5 0x00007fc35ba65ebc snd_pcm_areas_copy (libasound.so.2) #6 0x00007fc35baa6d95 n/a (libasound.so.2) #7 0x00007fc35ba77c1f n/a (libasound.so.2) #8 0x00007fc35ba77a59 n/a (libasound.so.2) #9 0x000000000051ba97 n/a (dring) #10 0x000000000051c118 n/a (dring) #11 0x000000000051cfad n/a (dring) #12 0x00007fc357787c40 execute_native_thread_routine (libstdc++.so.6) #13 0x00007fc359ec2424 start_thread (libpthread.so.0) #14 0x00007fc356efacbd __clone (libc.so.6) The next time it crashes, I will have debug symbols in dring. I can also recompile alsa-lib with debug symbols, what is the best way to do that? Looking around, it seems other projects have run into the same issue: https://aur.archlinux.org/packages/ultrastardx-git/?comments=all#comment-43… https://aur.archlinux.org/packages/zoom/#comment-544696 http://ubuntuforums.org/showthread.php?t=2248373 https://github.com/js-platform/node-webrtc/issues/110 https://fedorahosted.org/fldigi/ticket/70 The output of the alsa-info.sh script on my system is at [3]. What else can I provide to debug this issue further? Thanks, Baptiste [1] https://ring.cx [2] https://tuleap.ring.cx/plugins/tracker/?aid=502 [3] http://www.alsa-project.org/db/?f=0dd2ba1021b3d535f30f07c55dc18e2ef60db26d

[alsa-devel] [PATCH 1/2] ASoC: rt5645: patch reg-0x8a
by Bard Liao 01 Jul '16

01 Jul '16

reg-8a assign the tracking source for each ASRC tracker. The default value is 0x0000 which means all ASRC trackers will track LRCK1. But in most cases, we wish each ASRC tracker track the corresponding LRCK. i.e. ASRC1 tracks LRCK1, ASRC2 tracks LRCK2 and so on. So, we rewrite reg-8a as 0x0120.

[alsa-devel] [PATCH 0/3] ALSA: add dimension information validator
by Takashi Sakamoto 30 Jun '16

30 Jun '16

Hi, This patchset is to add a validator of dimension information for drivers in kernel/userspace. The dimension information was added to ALSA control interface. With the information, members in an element compose multi-dimensional matrix. For example, this matrix can be used for row/column table with values. In this case, dimension level 1 and 2 are utilized to describe the number of rows and columns by element member unit. When dimension information has no contradictions to the number of members in an element, there's no problem. Once it has, it can cause an issue. In worst case, it can cause buffer-overrun in userspace. The aim of this patchset is to prevent this situation.

[alsa-devel] [PATCH v2 0/4] ASoC: sunxi: Add i2s controller support

Hi everyone, This is the second version of the I2S support for the controller found in the Allwinner A10 and later SoCs. Playback has been tested with an UDA1380 on an A20-Olinuxino. Capture is not implemented yet, but will come eventually. Let me know what you think, Maxime Changes from v1: - Fixed bogus indentation and spurious whitespaces / newlines - Moved the device initialisation in the probe to the startup function - Disabled the device in shutdown - Removed function to get wss and sr to inline them in hw_params - Changed the way to access the divider array - Checked clk_set_rate return code - Fixed condition for invalid bclk and mclk dividers - Added sound-dai-cells to the bindings documentation required properties Emilio López (1): ARM: sun7i: Add mod1 clock nodes Maxime Ripard (3): ASoC: sunxi: Add A10 I2S controller binding documentation ASoC: sunxi: Add Allwinner A10 Digital Audio driver ARM: sun7i: Add DAI nodes .../devicetree/bindings/sound/sun4i-i2s.txt | 34 + arch/arm/boot/dts/sun7i-a20.dtsi | 87 ++- sound/soc/sunxi/Kconfig | 9 + sound/soc/sunxi/Makefile | 2 +- sound/soc/sunxi/sun4i-i2s.c | 703 +++++++++++++++++++++ 5 files changed, 832 insertions(+), 3 deletions(-) create mode 100644 Documentation/devicetree/bindings/sound/sun4i-i2s.txt create mode 100644 sound/soc/sunxi/sun4i-i2s.c -- 2.9.0
