[PATCH] drm/i915: Add has_psr-flag to gen9lp

[PATCH] drm/i915: Add has_psr-flag to gen9lp

[David Weinehall]

While testing Jim Bride's latest batch of PSR patches I noticed
that gen9lp doesn't include the has_psr flag, and that our GLK
system thus reported PSR as unsupported.

This patch simply adds has_psr.

SKL isn't GEN9LP, so this is unrelated.

PineView isn't GEN9LP, so this is also unrelated.

Re: [PATCH] drm/i915: Add has_psr-flag to gen9lp

[Rodrigo Vivi]

a long time ago I had agreed with Daniel that we would only add new
platforms after it was enabled by default on previous platforms.
a big reason for that is that we was willing to reduce the platforms
to validate and do better validation one by one before enabling.

However now I believe it would be beneficial to have that supported
added so we can get more brave people using in different platforms so
we could capture more corner cases before we enable it by default.
Also we can still enable by default one platform at time if needed.

So:

I also checked the spec to see if there was anything else new or
different for these platforms and didn't find anything so:

Reviewed-by: Rodrigo Vivi <rodrigo.vivi@intel.com>

But let's wait a bit to merge to give Daniel or others a time to nack ;)

Cheers,
Rodrigo.

A bit more testing shows that while our GLK systems work perfectly fine
with PSR (and gets the expected power savings), the BXT system we tested
on didn't cope quite so well.  I'll have to dig into this a bit to see
if there's something Broxton-related info on PSR in Bspec I missed,
or if it's just our BXT-P RVP that's buggy.

An update: while testing revealed that our BXT-P RVP doesn't work with
PSR, the GLK definitely does. CI would like to do PSR testing on GLK,
which obviously isn't possible if PSR is reported as unsupported on GLK.

Based on BSpec alone the PSR failure on BXT-P shouldn't be a
Broxton/Apollo Lake issue, but rather an issue with the RVP board
(or the panel), so I'd say that this patch still makes sense.

After all it only changes gen9lp to report that they *can* support PSR
(thus allowing for testing of PSR on such platforms), it doesn't enable
it by default.

So I'd like to nudge once more that this patch be merged.

Daniel, any objections?

It would be very important if we could narrow down the issue on BXT.
Panel?! Bios?! Missing Workaround? Different user space?
One of the biggest problem with PSR is that when it works well in all
machines we have and we enable it we end up finding someone in the
community with a machine that does not work well. We have an opportunity to
investigate and understand very well what are the issues on this BXT. We
shouldn't loose track of it.
And maybe adding that to CI we will be forced to record the bug! ;)

I agree. Let's add it. Also good to enable on CNL as well. If the panel
that you have there on CNL that is on CI doesn't support it you are about
to recurve some panels that does support PSR2.

Agreed. I haven't been able to find any newer BIOS for that device,
the user space should be the same.

Missing workaround might well be the case, and the panel is definitely
not the same as the one the GLK has. We have several other panels that
could be tested with though.

"Luckily" I own one of those machines :P

That opportunity is now rapidly fleeing, since the HW in
question is a BXT B0, for which the "drop workarounds" patch series
has already been submitted and gotten a R-B.

Yeah, enabling on CNL too makes sense and getting systematic PSR2 testing
would be awesome.

"recurve" => "receive"?

Agree. But since it was a while ago I was trying to hit CI retest on that,
but I couldn't. So could you please resubmit? I just want to see if that
will cause some noise that will force us to file a bug so CI doesn't start
flip-floping again because of this.

nevermind... on another review I notice cnl is already there imported from HSW_FEATURES.

yeap...
(phone auto-corrector believe recurve is the best option for recieve than receive :))

Thanks,

This seems relevant, and promising.
