[alsa-devel] [PATCH v2 00/15] ASoC: qcom: Add support to QDSP6 based audio
by srinivas.kandagatla＠linaro.org 14 Dec '17

14 Dec '17

From: Srinivas Kandagatla <srinivas.kandagatla(a)linaro.org> This patchset aims to provide a very basic version of QCOM DSP based audio support which is available in downstream andriod kernels. This patchset only support Digital audio based for HDMI-RX and will add support to other features as we move on. QDSP has both static and dynamic modules. static modules like AFE (Audio FrontEnd), ADM (Audio Device Manager), ASM(Audio Stream Manager) and CORE to provide this audio services. All these services use APR (Asynchronous Packet Router) protocol via smd/glink transport to communicate with Application processor. More details on each module is availble in there respective patch. This patchset is tested on DB820c, with HDMI audio playback on top of mainline, also tested slimbus analog audio using wcd9355 with an additional small patch.

[alsa-devel] [PATCH] ALSA: rawmidi: Avoid racy info ioctl via ctl device
by Takashi Iwai 14 Dec '17

14 Dec '17

The rawmidi also allows to obtaining the information via ioctl of ctl API. It means that user can issue an ioctl to the rawmidi device even when it's being removed as long as the control device is present. Although the code has some protection via the global register_mutex, its range is limited to the search of the corresponding rawmidi object, and the mutex is already unlocked at accessing the rawmidi object. This may lead to a use-after-free. For avoiding it, this patch widens the application of register_mutex to the whole snd_rawmidi_info_select() function. We have another mutex per rawmidi object, but this operation isn't very hot path, so it shouldn't matter from the performance POV.

[alsa-devel] [PATCH v4 0/5] TDA1997x HDMI video receiver
by Tim Harvey 14 Dec '17

14 Dec '17

This is a v4l2 subdev driver supporting the TDA1997x HDMI video receiver. I've tested this on a Gateworks GW54xx/GW551x with an IMX6Q which uses the TDA19971 with 16bits connected to the IMX6 CSI. For this configuration I've tested both 16bit YUV422 and 8bit BT656 parallel video bus modes. While the driver should support the TDA1993 I do not have one for testing. Further potential development efforts include: - CEC support - HDCP support - mbus format selection support for bus widths that support multiple formats - TDA19972 support (2 inputs) Media graphs can be found at http://dev.gateworks.com/docs/linux/media History: v4: - move include/dt-bindings/media/tda1997x.h to bindings patch - clarify port node details in bindings - fix typos - fix default quant range for VGA - fix quant range handling and conv matrix - add additional standards and capabilities to timings_cap v3: - fix typo in dt bindings - added dt bindings for GW551x - use V4L2_DV_BT_FRAME_WIDTH/HEIGHT macros - fixed missing break - use only hdmi_infoframe_log for infoframe logging - simplify tda1997x_s_stream error handling - add delayed work proc to handle hotplug enable/disable - fix set_edid (disable HPD before writing, enable after) - remove enabling edid by default - initialize timings - take quant range into account in colorspace conversion - remove vendor/product tracking (we provide this in log_status via infoframes) - add v4l_controls - add more detail to log_status - calculate vhref generator timings - timing detection fixes (rounding errors, hswidth errors) - rename configure_input/configure_conv functions v2: - encorporate feedback into dt bindings - change audio dt bindings - implement dv timings enum/cap - remove deprecated g_mbus_config op - fix dv_query_timings - add EDID get/set handling - remove max-pixel-rate support - add audio codec DAI support - added media-ctl and v4l2-compliance details v1: - initial RFC Media device topology: # media-ctl -d /dev/media0 -p Media controller API version 4.13.0 Media device information ------------------------ driver imx-media model imx-media serial bus info hw revision 0x0 driver version 4.13.0 Device topology -

[alsa-devel] [alsa-lib][PATCH v3 4/4] pcm: plug: add SND_PCM_FORMAT_{S, U}20 to linear_preferred_formats
by Maciej S. Szmigiero 14 Dec '17

14 Dec '17

This commit adds the recently added formats SND_PCM_FORMAT_{S,U}20 to the linear_preferred_formats array in pcm_plug. Let's give them lower priority than more standard S24 formats but a higher priority than less typical 3-byte versions. Signed-off-by: Maciej S.

[alsa-devel] [alsa-lib][PATCH v3 3/4] pcm: linear, route: handle linear formats with 20-bit sample on 4 bytes
by Maciej S. Szmigiero 14 Dec '17

14 Dec '17

The previous patch has added 20-bit PCM formats SND_PCM_FORMAT_{S,U}20 to alsa-lib. We need to extend the linear format conversion code with handling of these sample formats so they can also be utilized by applications that only recognize the more typical ones like SND_PCM_FORMAT_S16. Since the conversion arrays are indexed by a format bit width divided by 8 the easiest way to handle these formats is to treat them like they were 40-bit wide (the next free integer multiple of 8 bits). This doesn't create a collision risk with a future format since there can't really be a 40-bit sample format that occupies 4 bytes. Make sure we use the getput conversion method for these formats since a direct conversion from / to them is not supported. Signed-off-by: Maciej S.

[alsa-devel] [alsa-lib][PATCH v3 2/4] pcm: add and describe SND_PCM_FORMAT_{S, U}20
by Maciej S. Szmigiero 14 Dec '17

14 Dec '17

This patch adds and describes in various functions that query format properties SND_PCM_FORMAT_{S,U}20 formats that were recently added to the kernel as SNDRV_PCM_FORMAT_{S,U}20. These formats are similar to existing 20-bit PCM formats SND_PCM_FORMAT_{S,U}20_3, however they occupy 4 bytes instead of 3. Signed-off-by: Maciej S.

[alsa-devel] [PATCH] ASoC: sun4i-i2s: Show detailed error when DAI configuration callbacks fail
by Chen-Yu Tsai 14 Dec '17

14 Dec '17

When any of the DAI hardware configuration callbacks (.hw_param, .set_fmt, .set_sysclk) fails, there is no explanation about why it failed. This is particularly confusing for .hw_param, which covers many parameters of the DAI. Telling the users what parameter isn't supported, and what the requested value was goes a long way for developers trying to combine sun4i-i2s with external codecs. This patch adds dev_err calls explaining what isn't supported or failed, and what the value was. sun4i_i2s_set_clk_rate()'s first parameter was changed to a struct snd_soc_dai *dai, so we can get the underlying device.

In the first jack detection while booting, the result will always show as headset, even we insert the headphone.

[alsa-devel] [PATCH] alsactl: Only start restore service when asoundrc file exists
by Ikey Doherty 14 Dec '17

14 Dec '17

This solves the chicken and egg problem on fresh installations whereby the alsa state file does not yet exist, and alsa-restore unit attempted to launch without first having a state file.
