[alsa-devel] [RFC PATCH 0/7] AC97 device/driver model revamp
by Robert Jarzmik 04 Sep '17

04 Sep '17

It all started in the pxa device-tree submission here : https://lkml.org/lkml/2016/2/25/965 It will be maintained in : git fetch https://github.com/rjarzmik/linux.git work/ac97 And now it transformed into this RFC, which would bring a ground for AC'97 devices closer to the linux device/driver model. This is just an RFC to see if we understand each other Mark. Amongst the driving ideas behind this RFC : - use device/driver model for AC'97 device/driver binding is based on vendor_id{1,2} - use auto-probe of the AC'97 bus to enumerate codecs and create devices - be compatible with previous platform_data model for codecs => this enables a smooth transition, where a codec (here wm9713) can be used either through platform_device or automatic discovery - struct snd_ac97 is not used This structure is really heavy, and doesn't represent an AC97 device, but rather an AC'97 codec internals IIUC. I think it's right place would be in include/sound/ac97/codec.h. This is also a problem for regmap adherence, hence the include/sound/ac97/compat.h. - a new AC'97 bus Kconfig is created This was done for a smooth transition ... let's see if it's a good idea. - split the AC'97 into : - the codec - the digital controller - the bus Amongst the things that are not all touched yet : - ac97_codec.c The generic AC'97 codec in sound/pci/ac97/ac97_codec.c has really a lot features, which are not at all PCI related. They could be transfered to sound/ac97, without the pci specific field. => this deserves a deep ahead thinking, which I'll do if the current approach is accepted by the communauty. The most important patch is 2/7 "ALSA: ac97: add an ac97 bus". This is the main evaluation point for the serie, the others are here so that I can test it all. Well, this is a long term effort, which might need a complete rewrite according to the comments it'll get. Let's expose it for comments and see how I can progress with it.

[alsa-devel] [PATCH v8 0/5] Add platform clock for BayTrail platforms
by Pierre-Louis Bossart 10 Jul '17

10 Jul '17

These patches specifically enable the audio MCLK required by Baytrail CR devices. It is the remaining part of a bigger set of patches (already merged in Mark Brown's tree) that enable sound for Baytrail CR devices (especially Asus T100TAF) [1]. They include the clock driver and clock enabling in the pmc_atom code (along with moving of the non-architectural pmc_atom driver code into drivers/platform/x86 as suggested by Thomas Gleixner [2]). This move includes a new header in include/linux/platform_data/x86/. While there is an agreement that the definitions for PMC clocks are not really platform data this location is seen as a good-enough compromise with an agreement between Darren Hart and Andy Shevchenko [3] [1] http://mailman.alsa-project.org/pipermail/alsa-devel/2016-August/111704.html [2] http://mailman.alsa-project.org/pipermail/alsa-devel/2016-October/113936.ht… [3] http://mailman.alsa-project.org/pipermail/alsa-devel/2016-December/115892.h… Changes from v7: - Replaced clk-readl/writel by regular readl/writel - Fixed two nitpick comments (newline and driver name string) - Fixed [5:0] to [0..5] in comment (missed in v6) Changes from v6: - Addressed comments from Stephen Boyd, Andy Shevchenko and Vinod Koul - Renamed clk-byt-plt to clk-pmc-atom - Rebase to 4.10-rc3 (broonie/for-next) - Added helper functions to make error handling more compact - Removed module-related code since it's not possible/supported - Removed useless tests on remove - PMC_CLK_OFFSET move to clk-pcm-atom (more logical) - Split typo correction and makefile fix in separate patches - small fixes (spaces, defaults in switches, alphabetical order, use of clk_writel/readl and no test on write, simpler error handling, use of while(i--), unsigned loop variables, kernel doc fields, format-patch -M -C -D, use of PLATFORM_DEVID_NONE) Changes from v5: - fix build error reported by kbuild test robot - split the clk driver code from x86 platform changes Changes from v4: - move the pmc_atom driver from arch/x86/platform/atom to drivers/platform/x86 Changes from v3: - replace devm_kzalloc with devm_kcalloc - add x86 architecture maintainers Changes from v2: - move clk platform data structures to a separate include file - store clk_hw pointer for the fixed rate clocks Changes from v1: - register the clk device as child of pmc device - pass iomem pointer from pmc driver to clk driver to avoid using pmc_atom_read()/write() and use readl/writel API instead - use devm_clk_hw_register/clkdev_hw_create instead of clk_register/clkdev_create Irina Tirdea (3): clk: x86: Add Atom PMC platform clocks arch/x86/platform/atom: Move pmc_atom to drivers/platform/x86 platform/x86: Enable Atom PMC platform clocks Pierre-Louis Bossart (2): clk: Make x86/ conditional on CONFIG_COMMON_CLK platform/x86: fix typo in comment arch/x86/Kconfig | 4 - arch/x86/platform/atom/Makefile | 1 - drivers/acpi/acpi_lpss.c | 2 +- drivers/clk/Makefile | 2 + drivers/clk/x86/Makefile | 1 + drivers/clk/x86/clk-pmc-atom.c | 371 +++++++++++++++++++++ drivers/platform/x86/Kconfig | 5 + drivers/platform/x86/Makefile | 1 + .../atom => drivers/platform/x86}/pmc_atom.c | 88 ++++- include/linux/platform_data/x86/clk-pmc-atom.h | 44 +++ .../linux/platform_data/x86}/pmc_atom.h | 2 +- 11 files changed, 506 insertions(+), 15 deletions(-) create mode 100644 drivers/clk/x86/clk-pmc-atom.c rename {arch/x86/platform/atom => drivers/platform/x86}/pmc_atom.c (87%) create mode 100644 include/linux/platform_data/x86/clk-pmc-atom.h rename {arch/x86/include/asm => include/linux/platform_data/x86}/pmc_atom.h (98%) -- 2.7.4

[alsa-devel] additional high input device for snd-dice (A&H Zed R16)
by Allan Klinbail 26 Jun '17

26 Jun '17

Hi, I noticed on the changelog that some devices are able to access all channels without doing any .asoundrc funkiness. Form 4.6 kernel onwards - Add support for previously unavailable higher PCM channels on certain devices with high channel count, notably Focusrite Saffire PRO 40, Focusrite Liquid Saffire 56, and TC Electronic Studio Konnekt 48. These devices spread the PCM and MIDI channels across 2 tx + 2 rx IEEE 1394 channels instead of just 1 tx + 1 rx IEEE 1394 channel, as most other devices do. Pretty sure I've tested with 4.6 and wasn't able to achieve this with my device. But can test again with 4.8 if I am wrong. My device is an Allen and Heath Zed R16.. While latency performance in the way ALSA works is not satisfactory for my usage others may wish to use this device with ALSA for simplicity. (remove the need for FFADO entirely as there is no software mixer for this device and remove the need for any MIDI bridge) Currently under ALSA in 44.1k or 48k the device has 16 inputs and 16 outputs on the first firewire channel, and then and additional 10 ins and 10 outs on the second. If this is any help, here is the vendor info, as used by FFADO { # Allen and Heath Zed R16. Information from Brendan Pike. vendorid = 0x000004C4; modelid = 0x00000000; vendorname = "Allen and Heath"; modelname = "Zed R16"; driver = "DICE"; mixer = "Generic_Dice_EAP"; } On that latency topic- just voicing my opinion and I don't expect change. When the paradigm of using periods/frames and buffers is common across all OS and driver platforms, I don't believe that the driver should force developers to implement a new method, even if there are better ways of doing things. That might be okay for small open source projects, but bigger commercial applications would not be likely to maintain separate configuration options for Linux, they are more likely to drop Linux altogether if forced to adopt I also know that Takashi S, does not agree but as FFADO devs have agreed to keep the driver in FFADO I don't mind..

If yes, can't we simply remove this volume instead? thanks, Takashi

[alsa-devel] [PATCH 0/7] of_graph: prepare for ALSA graph support
by Kuninori Morimoto 17 May '17

17 May '17

Hi Rob, Mark Cc Guennadi, Laurent Now OF graph is mainly used by V4L2 SoC, and ALSA SoC is using different style for SoC <-> Codec binding. But, for example, HDMI case, V4L2 <-> ALSA need to collaborate, and then ALSA SoC needs to adjust to OF graph. OTOH, V4L2's "OF graph" position is same as ALSA SoC "sound card" position. And ALSA SoC side want to keep existing supported feature on new OF graph style. I'm posting this on ALSA SoC ML now. Now, current of_graph is indicating port/endpoint, but there is no way to understand that it is for video port ? or sound port ? or other device port ? For example, HDMI has video port, and sound port. Because of this reason, ALSA SoC side can't handle OF graph correctly. Thus, this patch-set tries to add new "type" on OF graph. And this patch-set includes small feature which are useful for ALSA SoC side OF graph support.

[alsa-devel] [PATCH 1/1] ASoC: fsl_asrc: use dma_transfer_direction enum when calling dmaengine_prep_dma_cyclic
by Nicolas Iooss 21 Apr '17

21 Apr '17

When fsl_asrc_dma_prepare_and_submit() calls dmaengine_prep_dma_cyclic(), it uses either DMA_TO_DEVICE or DMA_FROM_DEVICE. These values are both items of dma_data_direction enum, not of dma_data_direction enum, which is the type expected by dmaengine_prep_dma_cyclic(). Replace DMA_TO_DEVICE with DMA_MEM_TO_DEV and DMA_FROM_DEVICE with DMA_DEV_TO_MEM to fix this type mismatch issue.

[alsa-devel] PROBLEM: Internal microphone (& combined headset jack, in default config) not working on Acer VN7-592G (Skylake)
by Ralf Jung 04 Apr '17

04 Apr '17

Hi all, (This is my first bugreport to a mailing list, so I hope I'm filling out everything properly here...) [1.] Internal microphone (& combined headset jack, in default config) not working on Acer VN7-592G (Skylake) [2.] The internal microphone of my new laptop, an Acer Aspire V Nitro Black Edition (VN7-592G) with Skylake, is not working. The machine has a single "headset" jack which is supposed to support both speakers, microphones, and "combined jacks" that carry both audio-in and audio-out (like they are common on smartphones). Without any further configuration, the jack works only for external speakers. A plugged-in microphone doesn't seem to do anything, for a combined headset (i.e. sth. with both microphone and speaker in one jack), only the speaker part works. I tried all combinations of settings in pavucontrol, i.e., "Speakers" (that's the internal ones) vs. "Headphones" for audio output and "Microphone" vs. "Headset Microhpone" for the audio input. I was able to improve the situation by adding this to modprobe.d: options snd-hda-intel model=dell-headset-multi Now, mics and external speakers plugged in work fine (where for mics, I need to manually configure them in pacuvontrol: "Speakers" and "Microphone"). Combined headsets also work (with "Headphones" and "Headset Microphone"), i.e. I get audio in and audio out, but the audio in from the microphone is fairly noisy. I am not sure whether this is due to the headset or the laptop; I am using the same headset with my phone and people I called did not complain about noise. Furthermore, there is a weird effect: I have a headset with *separate* plugs for speaker and mic (which I used above to test the speaker vs. mic functionality). If I plug in the speaker part, but configure it as a microhpone (out: "Speakers", in: "Microphone"), then I actually get a (rather noisy) input signal. Not sure what is going on there, but I'm reasonably sure it is getting that signal from the headset, not the internal mic of the laptop. Even with this configuration, the internal microphone of the laptop dos not work. The system seems entirely unaware that there even is an internal microphone. Here's a Ubuntu bugreport with other folks having the same problem: <https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1523100> [3.] Keywords: audio microphone skylake combined-jack [4.] Kernel information [4.1.] Kernel version (from /proc/version): Linux version 4.9.1 (r@r-schwarzschild) (gcc version 6.2.1 20161124 (Debian 6.2.1-5) ) #1 SMP Sun Jan 8 11:40:58 CET 2017 This is a vanilla kernel compiled myself; I'm otherwise on Debian testing amd64.

[alsa-devel] [PATCH v2 1/2] ASoC: wm8960: Let wm8960 codec driver manage its own MCLK
by Zidan Wang 04 Apr '17

04 Apr '17

From: Zidan Wang <b50113(a)freescale.com> When we want to use wm8960 codec, we should enable its MCLK in machine driver. It's reasonable for wm8960 codec driver to manage its own MCLK. When current bias_level is SND_SOC_BIAS_ON, it is preparing for a transition away from ON. In this case, disable the codec mclk. When current bias_level is not SND_SOC_BIAS_ON, it preparing for a transition to ON. In this case, enable the codec mclk.

[alsa-devel] [PATCH 0/7] DisplayPort audio support on Cherrytrail
by Takashi Iwai 31 Mar '17

31 Mar '17

Hi, the following patches enable DisplayPort Audio on Cherrytrail machines when applied on top of my topic/intel-lpe-audio branch. Tests of DP audio were run on Dell Wyse 3040. The regression test were performed on Baytrail (Compute Stick) and Cherrytrail (Zotac PI330) in HDMI mode. On Cherrytrail there were no issues changing between HDMI and DP connectors dynamically. Could you i915 people review and give ACK if they are OK? The changes in drm/i915 side are fairly trivial, so I'd like to take them through sound git tree once after I receive your ACKs. Changes since RFC: - reordered and squashed patches - clean-up of register definitions and offsets (based on feedback from Jani/Ville) - unmute amp for both HDMI and DP unconditionally - mute amp on invalid ELD (unplug) - remove test for chicken bit which seems to have no effect in hardware - cosmetic edits to make checkpatch happy - change i915 notification argument to pass the plataform device instead Most of hard work in this patchset has been done by Pierre, so all credits go to him. thanks, Takashi === Pierre-Louis Bossart (4): drm/i915: add DP support in LPE audio mode drm/i915: add DisplayPort amp unmute for LPE audio mode ALSA: x86: intel_hdmi: add definitions and logic for DP audio ALSA: x86: Use config base depending on the pipe Takashi Iwai (3): drm/i915: Avoid MST pipe handling for LPE audio drm/i915: Pass pipe to LPE audio notification drm/i915: Pass platform device to LPE audio notifier drivers/gpu/drm/i915/i915_drv.h | 3 +- drivers/gpu/drm/i915/i915_reg.h | 10 ++ drivers/gpu/drm/i915/intel_audio.c | 38 +++++--- drivers/gpu/drm/i915/intel_lpe_audio.c | 28 +++++- include/drm/intel_lpe_audio.h | 7 +- sound/x86/intel_hdmi_audio.c | 173 ++++++++++++++++++++++++++++----- sound/x86/intel_hdmi_audio.h | 8 +- sound/x86/intel_hdmi_lpe_audio.c | 83 ++++++++++++---- sound/x86/intel_hdmi_lpe_audio.h | 29 ++++++ 9 files changed, 315 insertions(+), 64 deletions(-) -- 2.11.0
