Screen flicckering due to "drm/amdgpu: enable gfxoff again on raven series"

Screen flicckering due to "drm/amdgpu: enable gfxoff again on raven series"

[Pinky]

Hello,

I have today compiled the drm-next kernel from (1) and find out the screen is
flickering and shows various artifacts. By bissecting I found the cause
is commit 005440066f929ba0dca8f4e0aebfbf8daac592cc. By reverting it the
problem went out.

I does not have idea about what to do next. Sorry if this should be posted to
some bugzilla instead, I have got a bit lost. If so, would You please
point my out what to do?

With best regards,
    Pinkava J.

This may be related to stutter mode rather than gfxoff.  If so, there is a fix in the pipeline for that.  Does setting appending amdgpu.ppfeaturemask=0xfffdbfff on the kernel command line fix it?

Re: Screen flicckering due to "drm/amdgpu: enable gfxoff again on raven series"

[Pinky]

Yes, this one seems to be already in the drm-next branch (HEAD is
now 7cdd4dc58d28).

Just for completenes, there seems to be few more (probably unrelated) bugs.
One with mouse (1), some artifact sometimes appear and terminal in X
sometimes display black instead of text when scrooling. I did not intend
to discuss this here, just mentioning it.

I'm not sure what is going on them.  You have RLC firmware version
53815 (0x0000d237) so gfx power gating is being disabled as of
083d022913f2f8c3bc1183a13874ad777b9f5bdd.

Does setting amdgpu.ppfeaturemask=0xfffd3fff fix the issue?

Re: Screen flicckering due to "drm/amdgpu: enable gfxoff again on raven series"

[Pinky]

Yes this seems to solve the issue, even amdgpu.ppfeaturemask=0xffff7fff
provides the same efect.

Hi Pinkava,

We have a similar issue that screen flickering caused by stutter mode.

But per your testing result, I am a bit confused.

You mentioned that "ppfeaturemask=0xfffd3fff" could be fixed the issue, but "0xfffdbfff" doesn't fix it.
However, this is the same configuration while you add below patch.  Because the gfxoff feature will be disabled while detect the RLC ucode is 53815 (0x0000d237).

Hello Ray,

sorry for confussion, I re-tested it, there are two separate bugs:

flickering - probably related to stutter mode bug
   (white flickering stripes on screen, )

artifacts - the original issue i have reported (broken but steady image)

5.1.0-rc2-1-next-git-g7cdd4dc58d28 - artifacts, flickering
  amdgpu.ppfeaturemask=0xffff7fff - flickering
  amdgpu.ppfeaturemask=0xfffdffff - artifacts
  amdgpu.ppfeaturemask=0xfffd7fff - OK

  amdgpu.ppfeaturemask=0xffffbfff - artifacts, flickering
  amdgpu.ppfeaturemask=0xfffdbfff - artifacts
  amdgpu.ppfeaturemask=0xfffd3fff - OK

Sorry again for confussion. Is there a patch for the shutter so I can
test it?

With best regards,
    Pinkava J.

Hersen, would you mind to share your patch to Pinkava? He want to give a test.
