[alsa-devel] [RFC PATCH v2 0/6] adapt SOF to use snd-hda-codec-hdmi
by Kai Vehmanen 06 Sep '19

06 Sep '19

Hi all, here's a second RFC round for this series that adapts SOF (and one example machine driver) to use snd-hda-codec-hdmi (patch_hdmi.c) codec driver instead of hdac_hdmi (soc/codecs/hdac_hdmi.c). The primary goal is to unify the HDMI codec implementation between DSP and non-DSP HDA configurations, offer same interface to user-space and reduce maintenance load for all. If the approach looks ok, I'll remove RFC from v3 and update the remaining machine drivers (this v2 still changes only one machine driver and thus the RFC tag). v2 changes: - Codec selection via module parameter. Concerns were raised that a Kconfig option will not be sufficient as the patch changes user-space mixer controls. Distro kernels will want to use same kernel config for all platforms and a kconfig control would apply to all drivers. To address this, a combination of a module parameter, and a default value set via kconfig, was added to the patchset. This allows distros to support different combinations with a single kernel build. To switch codecs for a specific machine, UCM file update can be deployed together with a change to modprobe parameter. This is somewhat complicated, so further feedback is very welcome whether this is enough. - In machine drivers that are shared with SST and SOF, added runtime detection for which codec is used. For SST, the old hdac-hdmi is always used. - One patch dropped from series. This patch is no longer needed (pcm handles now passed to codec driver). Feature and testing info: - Tested on multiple Intel platforms supported by SOF. - Tested with ALSA console tools as well as with Pulseaudio. - requires Pulseaudio 12.x or newer, see https://lists.freedesktop.org/archives/pulseaudio-discuss/2019-August/03135… - HDMI, DP, DP-MST with multi-monitor use-scenarios work ok. - New feature for SOF: ELD /proc fs works just like in DSP-less mode. - New feature for SOF: jack detection works out-of-the-box with Pulseaudio (no need for card specific UCM for HDMI) - Pre-reviews at: https://github.com/thesofproject/linux/pull/1155 Kai Vehmanen (6): ALSA: hda - add mst_no_extra_pcms flag to hda_codec ASoC: Intel: skl-hda-dsp-generic: use snd-hda-codec-hdmi ASoC: hdac_hda: add support for HDMI/DP as a HDA codec ALSA: hda/hdmi - implement mst_no_extra_pcms flag ALSA: hda/hdmi - allow control creation without a linked pcm ASoC: SOF: Intel: add support for snd-hda-codec-hdmi include/sound/hda_codec.h | 1 + sound/pci/hda/patch_hdmi.c | 23 +++-- sound/soc/codecs/hdac_hda.c | 95 +++++++++++++++++--- sound/soc/codecs/hdac_hda.h | 12 ++- sound/soc/intel/boards/skl_hda_dsp_common.c | 28 +++++- sound/soc/intel/boards/skl_hda_dsp_common.h | 69 ++++++++++++++ sound/soc/intel/boards/skl_hda_dsp_generic.c | 7 -- sound/soc/sof/intel/Kconfig | 10 +++ sound/soc/sof/intel/hda-codec.c | 14 ++- sound/soc/sof/intel/hda.h | 6 +- 10 files changed, 231 insertions(+), 34 deletions(-) -- 2.17.1

[alsa-devel] [PATCH] ALSA: firewire-tascam: add note for FE-8
by Takashi Sakamoto 06 Sep '19

06 Sep '19

TASCAM FE-8 is the rest of model in TASCAM FireWire series. This device has no functionality to process audio signal and MIDI messages. Instead, it transfers control messages to host system corresponding to operations for some faders, buttons and knobs on its surface. Unlike the other devices in this series, the control messages are transmitted by asynchronous transactions. Some registers of device are used for registration of destination address for the transaction. The transaction includes quadlet-aligned data up to 32 quadlets. Userspace applications can receive the transaction and parse it for control message via Linux FireWire subsystem, without any support by ALSA firewire-tascam driver. Therefore the driver gives no support for it. This commit removes placeholder for FE-8 and add some comment for its functionalities as notes. $ python2 linux-firewire-utils/src/crpp < ~/git/am-config-rom/tascam/tascam-fe8.img ROM header and bus information block ----------------------------------------------------------------- 400 040f4798 bus_info_length 4, crc_length 15, crc 18328 (should be 14256) 404 31333934 bus_name "1394" 408 20ff7002 irmc 0, cmc 0, isc 1, bmc 0, cyc_clk_acc 255, max_rec 7 (256) 40c 00022eff company_id 00022e | 410 a094dcb7 device_id ffa094dcb7 | EUI-64 00022effa094dcb7 root directory ----------------------------------------------------------------- 414 0004bccc directory_length 4, crc 48332 418 0300022e vendor 41c 0c0083c0 node capabilities per IEEE 1394 420 8d000006 --> eui-64 leaf at 438 424 d1000001 --> unit directory at 428 unit directory at 428 ----------------------------------------------------------------- 428 0003eda4 directory_length 3, crc 60836 42c 1200022e specifier id 430 13800001 version 434 d4000004 --> dependent info directory at 444 eui-64 leaf at 438 ----------------------------------------------------------------- 438 0002461e leaf_length 2, crc 17950 43c 00022eff company_id 00022e | 440 a094dcb7 device_id ffa094dcb7 | EUI-64 00022effa094dcb7 dependent info directory at 444 ----------------------------------------------------------------- 444 0002ae47 directory_length 2, crc 44615 448 81000002 --> descriptor leaf at 450 44c 82000006 --> bus dependent info leaf at 464 descriptor leaf at 450 ----------------------------------------------------------------- 450 0004a79e leaf_length 4, crc 42910 454 00000000 textual descriptor 458 00000000 minimal ASCII 45c 54415343 "TASC" 460 414d0000 "AM" bus dependent info leaf at 464 ----------------------------------------------------------------- 464 0004a7d8 leaf_length 4, crc 42968 468 00000000 46c 00000000 470 46452d38 474 00000000 Signed-off-by: Takashi Sakamoto <o-takashi(a)sakamocchi.jp> --- sound/firewire/tascam/tascam.c | 4 +++- sound/firewire/tascam/tascam.h | 20 ++++++++++++++++++++ 2 files changed, 23 insertions(+), 1 deletion(-) diff --git a/sound/firewire/tascam/tascam.c b/sound/firewire/tascam/tascam.c index 231052db5680..addc464503bc 100644 --- a/sound/firewire/tascam/tascam.c +++ b/sound/firewire/tascam/tascam.c @@ -39,6 +39,9 @@ static const struct snd_tscm_spec model_specs[] = { .midi_capture_ports = 2, .midi_playback_ports = 4, }, + // This kernel module doesn't support FE-8 because the most of features + // can be implemented in userspace without any specific support of this + // module. }; static int identify_model(struct snd_tscm *tscm) @@ -214,7 +217,6 @@ static const struct ieee1394_device_id snd_tscm_id_table[] = { .vendor_id = 0x00022e, .specifier_id = 0x00022e, }, - /* FE-08 requires reverse-engineering because it just has faders. */ {} }; MODULE_DEVICE_TABLE(ieee1394, snd_tscm_id_table); diff --git a/sound/firewire/tascam/tascam.h b/sound/firewire/tascam/tascam.h index 64a2e4d2bbfe..15bd335fa07f 100644 --- a/sound/firewire/tascam/tascam.h +++ b/sound/firewire/tascam/tascam.h @@ -129,6 +129,26 @@ struct snd_tscm { #define TSCM_OFFSET_MIDI_RX_QUAD 0x4000 +// Although FE-8 supports the above registers, it has no I/O interfaces for +// audio samples and music messages.
