Revert "venus: firmware: Correct non-pix start and end addresses"

  This reverts commit a837e5161cfffbb3242cc0eb574f8bf65fd32640, which broke
probing of the venus driver, at least on the SC7180 SoC HP X2 Chromebook:

  [   11.455782] qcom-venus aa00000.video-codec: Adding to iommu group 11
  [   11.506980] qcom-venus aa00000.video-codec: non legacy binding
  [   12.143432] qcom-venus aa00000.video-codec: failed to reset venus core
  [   12.156440] qcom-venus: probe of aa00000.video-codec failed with error -110

Matthias Kaehlcke also reported that the same change caused a regression in
SC7180 and sc7280, that prevents AOSS from entering sleep mode during system
suspend. So let's revert this commit for now to fix both issues.

Hi Javier and Matthias,
Can we try the attached patch if that fixes the suspend issue for sc7180 and sc7280 ?

On my side the patch fixes the issue for sc7280, but not sc7180.

Some more info for sc7180:

[   10.313055] qcom-venus aa00000.video-codec: failed to reset venus core
[   10.331454] qcom-venus: probe of aa00000.video-codec failed with error -110

So venus didn't probe successfully. As a result sync_state() of its rpmhpd and
interconnects isn't called and they keep running at max speed, which prevents
the Always-On subsystem from suspending:

[   30.171148] qcom-rpmhpd 18200000.rsc:power-controller: Consumer 'aa00000.video-codec' did not probe (successfully)
[   30.682950] qnoc-sc7180 9680000.interconnect: Consumer 'aa00000.video-codec' did not probe (successfully)
[   30.701843] qnoc-sc7180 1740000.interconnect: Consumer 'aa00000.video-codec' did not probe (successfully)
[   30.720168] qnoc-sc7180 1638000.interconnect: Consumer 'aa00000.video-codec' did not probe (successfully)
[   30.738478] qnoc-sc7180 1500000.interconnect: Consumer 'aa00000.video-codec' did not probe (successfully)

(these debug logs are not upstream)

I tested your attached patch on an SC7180 machine (HP X2 Chromebook) and as Matthias
mentioned, it still causes the driver's probe to fail:

So what should we do about this folks? Since not allowing the driver to probe
on at least SC7180 is a quite serious regression, can we revert for now until
a proper fix is figured out?

I am able to repro this issue on sc7180 and discussing with firmware team on the cause
of reset failure. The original patch was raised for fixing rare SMMU faults during warm
boot of video hardware. Hence looking to understand the regressing part before we
proceed to revert.

Great, if you are working on a proper fix then that would be much better indeed.

Thanks for the follow-up!

Yeah, that's great, but OTOH: there is almost certainly just one week
before 6.2 will be released. Ideally this should be fixed by then.
Vikash, do you think that's in the cards? If not: why not revert this
now to make sure 6.2 works fine?

Hmm, no reply. And we meanwhile have Wednesday and 6.2 is almost
certainly going to be out on Sunday. And the problem was called "a quite
serious regression" above. So why not quickly fix this with the revert,
as proposed earlier?

Vikash? Javier?

I agree with you, that we should land this revert and then properly
fix the page fault issue in v6.3.

But it's not my call, the v4l2/media folks have to decide that.

In that case: Mauro, what's your opinion here?

No reply from Mauro and Linus chose to not apply the revert I pointed
him to. That at this point leads to the question:

Vikash, did you or somebody else make any progress to fix this properly?

We tried with different settings for the registers and arrive at a conclusion that
the original configuration was proper. There is no need to explicitly configure
the secure non-pixel region when there is no support for the usecase. So, in summary,
we are good to have the revert.

Stan, could you please help with the revert and a pull request having this revert
alongwith other pending changes ?

Vikash,

Could you or someone else from QC please Review/Ack these two patches,
since it seems that Stanimir moved on and maybe is not working in this
driver anymore?

You can find the thread and explanation of the issue here:

https://lore.kernel.org/lkml/Y+KPW18o%2FDa+N8UI@google.com/T/

But Stanimir already picked it and sent a PR for v6.3 including it.
  

Hi Javier, Dikshita, Stan,

the revert wasn't applied to v6.2 series. Can you please apply it and include it for v6.2.10?

While "media: venus: dec: Fix capture formats enumeration order" may have been
applied to v6.3, this still leaves the regression introduced by "venus:
firmware: Correct non-pix start and end addresses". As pointed out by Matthias
Kaehlcke, the commit prevents SC7180 and sc7280 AOSS from entering sleep mode
during system suspend. This is a serious regression in v6.2 kernel series.

To me it looks like it was submitted[1], but not yet applied even to the
media tree[2] -- while guess, maybe due problems mentioned in[3]? Or am
I missing something?

That fix is sitting in the media tree for a while and afaics still
hasn't been sent to Linus (which is needed to get this fixed in 6.2.y).

Mauro, could you maybe take care of that?

I see the revert made it to 6.3-rc5 as commit f95b8ea7. Now it just needs to
be included for v6.2.10

Thank you

I pointed Linus to this and he merged the revert directly; and it's
already queued for the next 6.2.y release:

Now to the remaining venus regression:

I only notice now: from [1] above it looks like that regression fix was
applied to a tree that seems to be intended for 6.4. Is that okay for
everybody, or should we ask Linus to pick this up as well (unless of
course Mauro shows up and forwards the patch, of course)? They fix a
regression from 5.19 afaics, so not a fresh problem, but apparently one
that bugged a few people recently.
