Description Vedran Miletić 2017-09-01 07:55:59 UTC 
I'm running https://cgit.freedesktop.org/~agd5f/linux/ branche amd-staging-drm-next on Vega 10. I have 3 AOC DisplayPort 1080p monitors connected to Vega's 3 DisplayPorts, regular cables, nothing funky.

I don't see anything obviously wrong or broken (presumably because I have no FreeSync-supporting display), but the following is reported by the kernel:

Comment 1 Dieter Nützel 2017-09-01 15:23:35 UTC 
I've reported this 2 times to amd-gfx-devel (Alex, Harry et al.) in the last several days. Was '[amd-staging-drm-next] kernel crash with amdgpu on RX580 in
'drm_object_property_get_value'.

Should be 'drm_object_property_[get|set]_value'.

Yes, it is _NO_ crash only warning (my bad) and it is _WORKED_ on.

Here comes what Alex mailed me about:

>> Was:
>> [amd-staging-drm-next] kernel crash with amdgpu on RX580 in
>> 'drm_object_property_get_value'
>>
>> I get this in _all_ current 'amd-staging-drm-next' versions. ;-(
>>
> It's not a crash, just a warning.  It's due to a recent change in the
> drm core, but we haven't gotten around to sorting it out yet.

Found it: https://lists.freedesktop.org/archives/amd-gfx/2017-August/012283.html

Guess I should subscribe to one more list. :-)

Maybe or I _should_ make better bug reports in the beginning...;-)

Comment 4 Dieter Nützel 2017-09-01 15:47:12 UTC 
This one is related, too:

Comment 5 Vedran Miletić 2017-11-03 22:24:19 UTC 
Fixed for me with Nov 2 commits.
Comment 6 dwagner 2017-11-04 15:48:28 UTC 
The recent patches to amdgpu made those annoying kernel warning messages go away for me, too. Along with them went some initialization and self-test messages, such as e.g.

> [drm] GPU post is not needed
> [drm] amdgpu: irq initialized.
> amdgpu: [powerplay] amdgpu: powerplay sw initialized
... which probably (hopefully) were not really relevant, either.
Comment 7 Dieter Nützel 2017-11-04 21:33:07 UTC 
Yes, I only can second it on RX580 (since some days ;-) ).

Should be CLOSED.
