[PATCH v2 00/17] ASoC: Intel: haswell and broadwell boards update

[PATCH v2 00/17] ASoC: Intel: haswell and broadwell boards update

[Cezary Rojewski]

A number of patches improving overall quality and readability of
haswell.c and broadwell.c source files found in sound/soc/intel/boards.
Both files are first renamed and only then actual changes are being
incrementally added. The respective names are: hsw_rt5640 and bdw_rt286
to match the pattern found in more recent boards.

Most patches bring no functional change - the more impactful patches at
are placed the end:

Refactor of suspend/resume flow for the bdw_rt286 board by dropping
dev->remove() in favour of card->remove() and adjust jack handling to
reduce code size slightly by implementing card_set_jack().

The last patch is removing of FE DAI ops. Given the existence of
platform FE DAI capabilities (either static declaration or through
topology file), this code is redundant.


Changes in v2:
- fixed wording error in patch 02/17 so it correctly mentions
  'haswell_rt5640', not 'broadwell_rt286'
- decided not to add kernel module names changes to this patchset so the
  review is not complicated unnecessarily. Will send them separately
  instead

Make use of 100 character limit and modify indentation so code is easier

While at it, rename local variable 'chan' to 'channels' to match
hsw_rt5640 board's equivalent.

[PATCH v2 16/17] ASoC: Intel: bdw_rt286: Refactor suspend/resume

[Cezary Rojewski]

Make use of card->remove() rather than pdev->remove() to unassign jack
during card unbind procedure.

To reduce code size, define unified jack setter in form of
bdw_rt286_set_jack() and invoke it during remove(), suspend_pre() and
resume_port().

This seems to have rather negative side effects in our modprobe/modprobe
-r tests?

The pattern of disabling the jack in the platform device .remove is
fairly common, I don't recall having seen a machine driver doing this in
the card .remove step. Are you sure this is equivalent?

Reverting this patch removes the kernel oops.

I don't have time to debug further - but this adds to my point of
minimizing risk on legacy code, doesn't it? suspend-resume is difficult
to get right, and easy to break. I have done the latter more often that
the former.

if you want to reproduce the issue, see
https://github.com/thesofproject/linux/pull/3696

Thanks for the report. Indeed, the latest "optimization" broke the 
card->remove() path.

Jacks are often initialized during dai_link initialization which is 
completely out of platform_device area. This report made me think 
further - if we assign jack in dai_link->init(), we should be able to 
drop it in dai_link->exit().

Not exactly! ->init() is done once card components are already accounted 
for (available for use) but snd_soc_link_exit() is called during 
snd_soc_remove_pcm_runtime() when card components are available no 
longer - soc_remove_link_components().

TLDR: teardown path is not symmetric with its counterpart, perhaps a 
problem yet to be addressed. I'll see if moving the jack-NULLing to 
codec's DAI ->remove() won't be a better temporary (?) solution than 
reverting to platform_device->remove() usage.


Mark,

Is it fine to leave v2 series as is, just ignoring this single 16/17 
patch? Or should I resend entire series as v3 without this very patch? 
I'd like to address the problem via a separate change.

It's a problem that impacted other platforms, see e.g.

static void kabylake_rt5660_codec_exit(struct snd_soc_pcm_runtime *rtd)
{
	struct kbl_codec_private *ctx = snd_soc_card_get_drvdata(rtd->card);

	/*
	 * The .exit() can be reached without going through the .init()
	 * so explicitly test if the gpiod is valid
	 */
	if (!IS_ERR_OR_NULL(ctx->gpio_lo_mute))
		gpiod_put(ctx->gpio_lo_mute);
}

I vaguely recall hitting this myself when working with codec properties.
It's worthy of a comment in the ASoC header to make sure this is better
known/shared.

I see in other drivers that the use of component_set_jack() is
symmetrical between .init and .exit, so far we haven't seen any issues
with sof_rt5682.c and others.

I'll send a separate mail where we can discuss the teardown path. Don't 
believe the problem can be ignored. Even for the bdw_rt286.c usage of 
link->exit() generates:

   rt286 i2c-INT343A:00: ASoC: DAPM unknown pin LDO1

the following is the cause:

soc_remove_component() calls both component->remove() and 
snd_soc_dapm_free() for the component (in that order) so when 
link->exit() finally gets executes DAPM widgets are no longer there.

Please ignore this question. I've opted to use link->exit() just like 
many other boards do and module reloads just fine. A separate thread 
will be opened for the card teardown flow discussion as mentioned by me 
earlier. link->exit() has its own problems too.

I'll send v3 tomorrow morning.

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark
