[alsa-devel] [PATCH v7 0/9] adapt SOF to use snd-hda-codec-hdmi

[alsa-devel] [PATCH v7 0/9] adapt SOF to use snd-hda-codec-hdmi

[Kai Vehmanen]

Hey,
here's the 7th round for this series that adapts SOF 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.

v7 changes:
- Only change since v6 is moving inlined logic from hda_dsp_common.h
  to hda_dsp_common.c and related changes to machine driver make rules.
  This is to address Takashi's feedback.
- Rebased on top of Mark's tree (agreed with Takashi and Pierre to
  submit via Mark's ASoC tree).

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/031358.html
 - 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)

[alsa-devel] [PATCH v7 1/9] ALSA: hda/hdmi - implement mst_no_extra_pcms flag

[Kai Vehmanen]

To support the DP-MST multiple streams via single connector feature,
the HDMI driver was extended with the concept of backup PCMs. See
commit 9152085defb6 ("ALSA: hda - add DP MST audio support").

This implementation works fine with snd_hda_intel.c as PCM topology
is fully managed within the single driver.

When the HDA codec driver is used from ASoC components, the concept
of backup PCMs no longer fits. For ASoC topologies, the physical
HDMI converters are presented as backend DAIs and these should match
with hardware capabilities. The ASoC topology may define arbitrary
PCMs (i.e. frontend DAIs) and have processing elements before eventual
routing to the HDMI BE DAIs. With backup PCMs, the link between
FE and BE DAIs would become dynamic and change when monitors are
(un)plugged. This would lead to modifying the topology every time
hotplug events happen, which is not currently possible in ASoC and
there does not seem to be any obvious benefits from this design.

To overcome above problems and enable the HDMI driver to be used
from ASoC, this patch adds a new mode (mst_no_extra_pcms flags) to
patch_hdmi.c. In this mode, the codec driver does not assume
the backup PCMs to be created.

[alsa-devel] [PATCH v7 2/9] ASoC: hdac_hda: add support for HDMI/DP as a HDA codec

[Kai Vehmanen]

Handle all HDA codecs using same logic, including HDMI/DP.

Call to snd_hda_codec_build_controls() is delayed for HDMI/DP HDA
devices. This is needed to discover the PCM device numbers as
defined in topology.

[alsa-devel] [PATCH v7 3/9] ASoC: Intel: skl-hda-dsp-generic: use snd-hda-codec-hdmi

[Kai Vehmanen]

Add support for using snd-hda-codec-hdmi driver for HDMI/DP
instead of ASoC hdac-hdmi. This is aligned with how other
HDA codecs are already handled.

When snd-hda-codec-hdmi is used, the PCM device numbers are
parsed from card topology and passed to the codec driver.
This needs to be done at runtime as topology changes may
affect PCM device allocation.

[alsa-devel] [PATCH v7 4/9] ASoC: Intel: skl-hda-dsp-generic: fix include guard name

[Kai Vehmanen]

Match the include guard define to actual filename. The source
directory now has an actual hda_dsp_common.h header, so the old
include guard may cause confusion.

[alsa-devel] [PATCH v7 5/9] ASoC: SOF: Intel: add support for snd-hda-codec-hdmi

[Kai Vehmanen]

Add support to implement HDMI/DP audio by using the common
snd-hda-codec-hdmi driver.

Change of codec driver affects user-space as the two
drivers expose different mixer controls. A new kernel
module option "use_common_hdmi" is added to user-space
to indicate which interface should be used. The default
driver can be selected via a Kconfig option.

instead of ASoC hdac-hdmi. This is aligned with how other
HDA codecs are already handled.

[alsa-devel] [PATCH v7 9/9] ASoC: Intel: bxt_rt298: common hdmi codec support

[Kai Vehmanen]

Add support for using snd-hda-codec-hdmi driver for HDMI/DP
instead of ASoC hdac-hdmi. This is aligned with how other
HDA codecs are already handled.

Should be NULL instead.

Hrm, this can be a problem.  I see there are multiple drivers that are
built with this object.  When they are built as modules and more than
one module get loaded on a system, it'll lead to a conflict because
both modules try to put the same stuff.

So, hda_dsp_common.o should be in the common helper module that is
used by both drivers, or we need other trick.

But I'm not entirely sure whether this is true on the recent kernel
build.  At least it *was* a problem in the past.

In anyway, please try to load the two modules on your system and check
whether the module loading works.


thanks,

Takashi

along the same lines, we have a Kconfig issue that I didn't see earlier.
These bxt parts will only compile with the Skylake driver with the 
upstream code, the following test applies:

if SND_SOC_INTEL_APL

In the SOF tree, we have a different test:

if SND_SOC_INTEL_APL || (SND_SOC_SOF_APOLLOLAKE && SND_SOC_SOF_HDA_LINK)

I kept this change back on purpose since we can only use APL+SOF on 
chromebooks with an experimental CoreBoot and only on pre-production 
hardware, but what this means is that GLK devices wouldn't work with 
SOF...I'll add this fix to my Kconfig update series.

Also I wonder if anyone tested bxt_rt298 with SOF? I see a topology for 
it but I've never seen any test results from anyone.

hmm, did a quick test and no problems seen, all modules load fine.

Another option is to go back to solution in v6 of the series and
have the helper functions inlines. But it seems v7 works as well, so maybe 
we'll stick with this.

ack, that's a good catch. I'll keep this machine driver change in
the series anyways (I want to include all machine drivers that are in 
upstream kernel and have the HDMI setup code).

No info about this. The patch in my series for bxt_rt298 is a mechanical 
update (it has the HDMI code for hdac-hdmi and it can be used with SOF/GLK 
-> driver updated in the series).

Hrm, then it might be built-in + module mixed case.  If that works, it
implies that my concern can be ignored.  Let's see.
