[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 1/2] ARM: tegra: remove Whistler support
by Stephen Warren 13 Jun '17

13 Jun '17

From: Stephen Warren <swarren(a)nvidia.com> Whistler is an ancient Tegra 2 reference board. I may have been the only person who ever used it with upstream software, and I've just recycled the board hardware. Hence, it makes sense to remove support from software.

[alsa-devel] [PATCH RFC 0/7] HDMI audio support for Exynos Odroid boards
by Sylwester Nawrocki 09 Jun '17

09 Jun '17

In this series I gathered patches touching various subsystems to make the overall review easier, finally I'm going to post independently patches for each subsystem and the dts patch(es) will be postponed to subsequent merge window. The main purpose of this series is to add audio codec interface to the Exynos DRM driver, so HDMI audio can be properly supported, also on boards where HDMI is the only connector available for audio. Currently in mainline the ASoC simple-card is used for Odroid XU3, I decided to change it and use a dedicated ASoC machine driver, which allowed to implemement specific clock settings (EPLL and the I2S root clock adjusted to audio sample rates) and to ensure proper number of audio channels gets negotiated in multicodec system configuration. This series is based on v4.11-rc6, has been tested on Odroid XU3.

[alsa-devel] Problems with the DP MST audio support patchset
by Pascal Wichmann 26 May '17

26 May '17

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Hello, I am not sure whether alsa-devel is the right place for this kind of question. If it is not, please tell me a better place for them. I am building my kernel against the drm-tip freedesktop repository which includes the patches from December 2016 (message id <1480992519-108079-1-git-send-email-libin.yang(a)intel.com> and follow-ups on alsa-devel). I am using a ThinkPad X250 and the ThinkPad Ultra Dock with the HDMI output connected to my YAMAHA HTR-2866; this hdmi output is seen as display port and uses DP MST from the dock. In principle, everything is working quite well; however, I frequently recognize two weird behaviours: * First of all, my audio receiver has 5.1 support. When I configure my laptop to send 5.1 audio using alsa or pulseaudio, there is only silence and no audio signal reaches the receiver; however, when I choose 7.1 digital surround (which my receiver actually does not suppo rt natively), everything works well and the two additional speakers are split to the existing ones (I do not know whether alsa/the kernel or the receiver does this, probably it is the receiver). This problem is pretty much only esthetical, as everything works fine if I use the 7.1 "work-around" (Digital Stereo does work also, but obviously does not support the full 5.1 setup) * The other problem -- which is actually very annoying -- is that there frequently is silence though there is audio playing; this happens now and then, but when there has been *no* output for a while, it always happens a few seconds after starting the new output and lasts for two to three seconds. During these periods of silence, the icons on my receiver indicating that there is an audio source are also gone. This problem occurs with 7.1 configuration as well as with Digital Stereo. I am not sure what these problems are caused by and do not know what kin d of debug information you may require to get more hints on how to solve them. Any hints are appreciated. Thank you for your advice, Pascal Wichmann -----BEGIN PGP SIGNATURE----- iQIzBAEBCAAdFiEE/gJ8Tpn0OtJz8hxD6+YIa34W/zYFAljbj5cACgkQ6+YIa34W /zbIVg//QP4A0wUE2MyaEAenN8nUpNV5ASglRTZ0N5hXBjD+B/sxIMkJdtSynlcB eBYL90ZLuFHxdfXsltifeY29D7CaHfyqQCeJUfzV+RgUGrlv0wqk2vA9Dfc+RTIT PBORlyuknqIV14z8vxMGO/1+Po/S8AFplK/QJs9Y+irGAX+CAhBMlVMt8V5rbL+e oD8KRWgPIwuYShhd0f3tmgqdhRn9RUQgBaYOaq1pXdI/nNDHZuRA021zytkkV4rR NGG2zOsgrrXo82ac1AAeUXlNczqUCM7UXNLjpVYUQQotEMZd9d6oL5/Iq/bD7Z8i Z+bzOWymzaaThqarc11UL9ngJr6JsDNXgdDrLgLbkSE1r6Knq66qzOmzZL7qeUDI 1JeCNkmztn82VLovRogQTY8p8Ye7gXwVUPNDocCoeBKgRA6u2VGs+zJljCDOiyT9 cCA+QGMpRMz+KLt82Bt5/vE6TzngUEOZli34wNhf6DaHYo+0j4TpiCZT3roIVlp+ C+tPvDsbt9SfVLKvmoDCKAS8o5wp7+jESAsTEMzssBeN6LYKTWeAJeZHymf17ckb Y3oub8Wk5bEvZh0AO5q7wqdWMLuTc9BSmJ8eJA0jNV+m9sGKxaTB/qFMfNoJjfFD yvBBeYvic0btTtOiQAPEia1igNR9vt1hpj5wCI6xNQwSekM1bOQ= =/6Dp -----END PGP SIGNATURE-----

[alsa-devel] HDA Intel ALC889A optical spdif input on MacBooks
by René Rebe 22 May '17

22 May '17

Hi, recently I wanted to connect my low noise mic pre-amp via optical spdif to a spare "10 year” old MacBook or MacBookPro. Those indeed have a optical input in the 3.5mm headphone jack. On macOS this also works and works as expected. On Linux, however, no matter what I do I only get zeros when recording the -D iec958. In /proc I see 3 capture sub-devices, where the 2nd is labeled: # cat /proc/asound/card0/pcm1c/info ... id: ALC889A Digital name: ALC889A Digital ... The behavior is the same on booth the MacBook as well as the MacBook Pro with either of those PCI devices: 00:1b.0 Audio device: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 02) 00:1b.0 Audio device: Intel Corporation 82801H (ICH8 Family) HD Audio Controller (rev 03) I have the feeling there could be some auto sensing be involved, as in the macOS system preferences I see the input switching from Mic to Optical Input as soon as I plugin in an active fibre. As I’m not familiar with this Intel HD stuff, any hint how to start analyzing and poking this mystery would be highly appreciated.
