[alsa-devel] ALSA: Soc_compress open file node allows more than once
by b_lkasam＠codeaurora.org 28 Dec '17

28 Dec '17

Hi ALSA team, This is regarding compress offload framework file operations wrt open system call. For open call to this driver currently allows for same node more than once. This may result in memleak issues or data corruption if same node in use by multiple instances. can we have restriction to avoid open of same node using some refcount? we can either have refcount under compr->private_data and cross check in below function before proceeding. static int snd_compr_open(struct inode *inode, struct file *f) Please suggest accordingly. Thanks Laxminath Kasam, Qualcomm.

[alsa-devel] [RFC v1] ALSA: xen-front: Add Xen para-virtualized frontend driver
by Oleksandr Andrushchenko 22 Dec '17

22 Dec '17

Hi, all! Foreword ======== This RFC is aimed to introduce support of para-virtualized sound frontend driver for Xen [1] and gather opinions from the relevant communities (ALSA, Xen). It implements the protocol from [2] with the following limitations: - mute/unmute is not supported - get/set volume is not supported Volume control is not supported for the reason that most of the use-cases (at the moment) are based on scenarios where unprivileged OS (e.g. Android, AGL etc) uses software mixers. Both capture and playback are supported. The relevant backend is implemented as a user-space application [3] and uses accompanying helper library [4]. Both frontend driver and backend were tested on real HW running Xen hypervisor (Renesas R-Car ARM based H3/M3 boards, x86). Discussion ========== During the first attempt to upstream the driver [5] number of comments and concerns were raised, one of the biggest flaws in the design were questioned by both Clemens Ladisch [6] and Takashi Sakamoto [7]: the absence of synchronization between frontend and backend during capture/playback. Two options were discussed: “In design of ALSA PCM core, drivers are expected to synchronize to actual hardwares for semi-realtime data transmission. The synchronization is done by two points: 1) Interrupts to respond events from actual hardwares. 2) Positions of actual data transmission in any serial sound interfaces of actual hardwares. “ and finally a change to the existing protocol was suggested: “In 'include/xen/interface/io/sndif.h', there's no functionalities I described the above: 1. notifications from DomU to Dom0 about the size of period for interrupts from actual hardwares. Or no way from Dom0 to DomU about the configured size of the period. 2. notifications of the interrupts from actual hardwares to DomU.” This is implemented as a change to the sndif protocol [8] and allows removing period emulation: 1. Introduced a new event channel from back to front 2. New event with number of bytes played/captured (XENSND_EVT_CUR_POS, to be used for sending snd_pcm_period_elapsed at frontend (in Linux implementation). Sent in bytes, not frames to make the protocol generic and consistent) 3. New request for playback/capture control (XENSND_OP_TRIGGER) with start/pause/stop/resume sub-ops. Along with these changes other comments on the driver were addressed, e.g. split into smaller chunks, moved the driver from misc to xen etc. Hope, this helps to get the full picture of what was discussed and makes it possible to move forward. Waiting for your valuable comments, Thank you, Oleksandr [1] https://github.com/andr2000/linux/commits/snd_upstream_v1 [2] https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/inc… [3] https://github.com/xen-troops/snd_be [4] https://github.com/xen-troops/libxenbe [5] https://lkml.org/lkml/2017/8/7/363 [6] http://mailman.alsa-project.org/pipermail/alsa-devel/2017-August/123617.html [7] http://mailman.alsa-project.org/pipermail/alsa-devel/2017-August/123744.html [8] https://github.com/andr2000/linux/commit/095d7feae00bf00c852c67c4f1044de560…

[alsa-devel] [PATCH v3 0/5] TDA1997x HDMI video receiver
by Tim Harvey 18 Dec '17

18 Dec '17

This is a v4l2 subdev driver supporting the TDA1997x HDMI video receiver. I've tested this on a Gateworks GW54xx 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 mode. 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) History: 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] Line6 Helix - usb compliant but not working correct
by Jens Verwiebe 14 Dec '17

Hi folks I recently got a Line6 Helix LT which can work usb compliant for example on OSX or IOS. No driver is needed but the samplerate is fixed to 48000 ( which is okay for the first ). Now i expected this device to work ootb in alsa, which turned out to be half the truth. Connecting the device threw " usb 7-2: parse_audio_format_rates_v2(): unable to retrieve number of sample rates (clock 16)" so i investigated a bit and found this workaround: --- "/media/Workdata3/Development/kernel_lowlat_4.4-97/linux-4.4.97/sound/usb/clock (Kopie).c" 2017-11-08 10:06:31.000000000 +0100 +++ /media/Workdata3/Development/kernel_lowlat_4.4-97/linux-4.4.97/sound/usb/clock.c 2017-11-14 23:06:51.750924051 +0100 @@ -361,6 +361,13 @@ static int set_sample_rate_v2(struct snd struct uac_clock_source_descriptor *cs_desc; clock = snd_usb_clock_find_source(chip, fmt->clock, true); + /* + * Line6 HELIX does not respond to sample rate + * set requests.

[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] [PATCH 0/6] ALSA: usb: UAC3. Add support for Basic Audio Device (BADD)
by Jorge Sanjuan 13 Dec '17

13 Dec '17

This adds functionality for the Basic Audio Device (BADD) subset that is defined in the USB Audio Class 3 (UAC3). The new class requires the device to have 3 usb configurations as follows: 1: Legacy Mode: UAC1 or UAC2. 2: BADD device with a prefined topology. (Minimum). 3: UAC3 device for more detailed description or more complex devices that can't be covered by the BADD profile. This patch series also includes some minor fixes to the usb card driver. Also, this has been implemented on top of the the patch which adds UAC3 support to the usb sound card driver: commit ddd452d7b04b86fb5f9285a19ac54deca9264ac1 Author: Ruslan Bilovol <ruslan.bilovol(a)gmail.com> Date: Tue Nov 7 04:01:20 2017 +0200 Jorge Sanjuan (6): ALSA: usb: ADC3: Add initial BADD spec support ALSA: usb: ADC3.

[alsa-devel] [PATCH v6 00/17] Add support for Cirrus Logic CS47L35/L85/L90/L91 codecs
by Richard Fitzgerald 13 Dec '17

13 Dec '17

The Cirrus Logic CS47L35, CS47L85, CS47L90/91 codecs are complex audio SoC devices. In addition to the core audio capability they have onboard GPIO, regulators, DSPs and interrupt controller and a large register map space accessed over SPI or I2C. This family of codecs is based around common IP blocks and they are managed by a set of common drivers referred to as "Madera".

[alsa-devel] Cherry Trail + RT5645 devices with a mono speaker ?
by Hans de Goede 08 Dec '17

08 Dec '17

Hi Pierre-Louis, Bard, I've been looking into getting some Cherry Trail + RT5645 devices with a mono speaker I have to work properly. Specifically the goal is to mix the right channel into the left output, so that sounds which are only played over the right channel do not get lost. I'm using this UCM file: https://github.com/plbossart/UCM/blob/master/byt-rt5640/HiFi Looking at the rtl5640 UCM file, getting the mono speaker to work (in a first simple attempt) should be as simple as replacing: cset "name='SPOR MIX SPKVOL R Switch' on" With cset "name='SPOL MIX SPKVOL R Switch' on" But this does not work, the speaker test sound for the right speaker is still silent (works with headphones). I've also looked into directly poking the RT5645_SPO_MIXER i2c register for testing, but when checking its value with the original unmodified UCM file: [root@localhost ~]# i2cget -y -f 1 0x1a 0x48 w 0x06c8 That is: 0xc806 as the output of i2cget "w" mode needs byteswapping. Note that both the RT5645_M_SV_L_SPM_L and RT5645_M_SV_R_SPM_L bits are already cleared, which is weird as this is before I've modified anything. Also the RT5645_M_SV_R_SPM_R bit is cleared, but that is expected. Even if I manually set reg 0x48 to 0x07c8 which AFAIK should enable output of both left and right channels on the left speaker I still only get sounds played on the left channel. Any insights / help with this would be very much welcome. Regards, Hans
