[PATCH 00/23] Intel SST driver update

[PATCH 00/23] Intel SST driver update

[Alan Cox]

This is a forward port of various further Intel work on the SST driver in
staging. This keeps the staging driver up to date while the ALSA driver
development continues.

[PATCH 01/23] intel_sst: Save audio state across D3 on Medfield

[Alan Cox]

From: Vinod Koul <vinod.koul@intel.com>

During suspend and runtime_suspend audio dsp will be in D3 state
and will loose its context.

This patch adds support in driver to save the dsp context
and restore this context during resume

This line is in the original patch from Vinod in this function that
added the driver to the tree (git commit id fffa1cca), so the patch
doesn't apply at all.  Do you see this too?

If I comment out this chunk, the patch fails later on as well:

patching file drivers/staging/intel_sst/intelmid.c
Hunk #1 FAILED at 805.
1 out of 1 hunk FAILED -- saving rejects to file drivers/staging/intel_sst/intelmid.c.rej


Which is odd.

What tree did you generate this series against?  I don't have any
outstanding sst patches in my "to-apply" queue, did I miss some that you
previously sent that I should have applied first?

confused,

I see it present in ffa1cca then removed then added back

I see the problem - Mark Brown took a patch in staging via the ASoC tree
which clashes with this.

fa880004682cf0d10e7a7c71dc8d56bbd67ac3d5

which is not only a staging patch but also breaks compilation of the code
because the sst_drv_ctx symbol isn't even exported or visible to the
intelmid module, which suggests it wasn't even compile tested.

Best plan seems to be for the patch Mark took to go into the staging tree
as well, and I'll then rebuild the patch stack on top of it and fix the
fact it didn't even build.

In general we have a bigger problem here, the ASoC driver appears to be
violating rule #1 of staging - nothing outside of staging should be using
or depending upon staging code in the first place.

I am assured that this patch is essential to build with the Intel
drivers that are currently upstream in ASoC, though I've not personally
verified that.  I'd not be surprised if the tests whoever submitted it
did had only been done with the module built in, though I'd have
expected whatever tests people do on -next to pick that up since x86
seems to be a popular target there.

To recap the previous discussion: staging is just not in the slightest
bit viable for ASoC stuff, code that does anything non-trivial is going
to get broken between releases.  Especially with something like this
where the drivers are for unreleased hardware that has no current end
users it's just not a problem for the core if drivers do stuff like this
so long as they don't do anything visibly bad or cause problems for the
people who do build test whatever architecture is affected.

Yes I know that - and its active development of a nice clean driver going
on upstream so doesn't belong there anyway. The ASoC driver should
probably have its own copy of the bits of the staging driver that it
needs however.

I can fix this collision up easily enough and if doing it not via the
rules is best fine by me. I think it might be wiser however if the ASoC
driver took its own copy of the bits it actually needed.

That sounds like a good idea.

Mark, can you try to let me know if you are patching staging code?  If
you want to "own" a driver in the staging tree, that's fine, just let me
konw and I'll funnel patches to you for it (we do that for other staging
drivers).

It's just that for times like this, when I have no idea that someone
else modified it in linux-next, and then patches fail to apply, that it
gets messy.

thanks,

I CCed you in on the thread where the patch was applied.  Probably you
forgot about it as it was described as a build fix for my tree.

I'm not really that interested in the Intel patches in staging, the bulk
of them require a from scratch rewrite to go upstream as they're so far
from following the Linux driver model for these things.

I must have, sorry about that.

Ok, then I guess I can handle them.

Alan, how do you want to go about sending patches that we can apply
somehow?

Best bet is to apply Mark's patch into your git tree then apply mine on
top I think. Git will see the same patch in both trees and resolve it all
nicely for -next.

Have a pointer to which patch that was?

It's 774fd7 (sst: fix compile error) which is in -next.

That's one of the, I needed another as well :)

Anyway, I've queued all of these up now so hopefully we should all be in
sync correctly.

Once you move over to proper CODEC drivers the core will take care of
this stuff for you.

Please see 00/23

"This is a forward port of various further Intel work on the SST driver in
staging. This keeps the staging driver up to date while the ALSA driver

[PATCH 04/23] intel_sst: ignore IRQ when suspended

[Alan Cox]

From: Vinod Koul <vinod.koul@intel.com>

The irq for audio is shared, so when device is supended driver should
not the read register and ignore the interrupt.

This patch ignores interrupts when device is suspended.

[PATCH 06/23] intel_sst: parameter tuning ioctl

[Alan Cox]

From: Vinod Koul <vinod.koul@intel.com>

This patch adds new IOCTL for application interface.

Using parameter tuning IOCTL, application can fine
tune the audio firmware for it's requirement.

[PATCH 08/23] intel_sst: rework jack implementation

[Alan Cox]

From: Ramesh Babu K V <ramesh.babu@intel.com>

This patch fixes the below issues w.r.t jack implementation

a) The current jack implementation in driver is implemented
   in intelmid.c. It has moved to vendor files for better managebility
b) Cleaned up jack reporting per upstream comments
c) Implemented jack for msic, added code to read adc and deduce jack
   type based on mic bias
d) Support detection of american headset

[PATCH 09/23] intel_sst: Set de-bounce time

[Alan Cox]

From: Lu Guanqun <guanqun.lu@intel.com>

In order to make jack detection behave properly, we have to set
the de-bounce time, otherwise, some weird events happens:
e.g. no plug-out event seen.

[PATCH 13/23] intel_sst: move jack detection related configs to init time

[Alan Cox]

From: Lu Guanqun <guanqun.lu@intel.com>

The old policy will not enable MIC2BIAS on Moorstown platform
by default, it's only enabled when the user selects HS_MIC as input source.
Therefore when user selects DMIC and then inserts the jack,
no interrupt will be generated to notify the driver about the
jack insertion event and to take action to auto mute the speaker.

The new policy will enable this bit by default,
then no matter what the output device is, an interrupt will be generated.

This behaviour is more likely what a user expects.

[PATCH 16/23] intel_sst: MRST can only do mono recording

[Alan Cox]

From: Wu Fengguang <wfg@linux.intel.com>

Fix bug

	$ arecord -Dplughw -c2
	Recording WAVE 'stdin' : Unsigned 8 bit, Rate 8000 Hz, Stereo
	arecord: set_params:1116: Unable to install hw params:
	ACCESS:  RW_INTERLEAVED
	FORMAT:  U8
	SUBFORMAT:  STD
	SAMPLE_BITS: 8
	FRAME_BITS: 16
	CHANNELS: 2
	[...]

Root cause is, the driver is reporting 2-channel capture capability
that is not supported by the MRST hardware. So the plughw plugin
end up requesting 2-channel capture which fails.

[PATCH 23/23] intel_sst: fix output noises when it's not in playback

[Alan Cox]

From: Lu Guanqun <guanqun.lu@intel.com>

When the corresponding output device is not in playback, we can hear a little
noises.

Fix it by powering on the device only when it's in playback.

What's the plan for moving these out of staging?  Quite a few of these
patches feel like moves in the wrong direction, adding more code that's
going to have problems with mainline rather than addressing the issues
that prevent merges.

There is a separate driver being written. In the meantime this driver is
getting updated and maintained because in the real world people have
customers and products to deliver.

It might as well therefore be maintained in tree as out. That seems to
serve Linux users rather better.

Sure, I was just asking if there was a plan to work on this properly -
the normal expectation in staging is that we'll see in place refactoring
and this series clearly isn't that.  You seem a little defensive here...

Of course, as do most of us, I was mostly making sure that there was a
plan here.

There I disagree (on both points). We have a collection of drivers in
staging some of which are in the 'refactor and move' category (eg SEP)
others of which are in the 'until the nice one is done' category - eg
much of the wireless stuff, rim4 and a few other drivers.

Yes there is a plan. SST essentially gets updated to fix stuff that needs
to work (eg runtime PM for Moorestown) but isn't the future. My favourite
sst patch is going to be the one which reads 'added 0 lines, removed
bazillions' because at that point it ceases to be my problem ;)
