More Radeon & AMDGPU Fixes Line-Up For Linux 4.10

[netkas]

Hello
I was able to get a log from this strange crash, in fact it's only driver crash, not whole system:

I meant the issue doesn't happen when amdgpu is not used, so the issue is in amdgpu.

[netkas]

it doesn't happen when I use nomodeset kernel option.
it doesn't happen when I run Unigine Valley.

[netkas]

Made a long test, after about 30 minutes the screen went black and system freezed (amdgpu, 4.11-wip)
any idea how I can retrive some logs in such situation?

[indepe]

It is fixed:
https://cgit.freedesktop.org/~agd5f/...1047fc08e6a5a9
This proves that amd reacts fast and end users, use the wip kernel.

Thanks for letting us know! I suppose this works on standard builds once admgpu supports Tahiti cards by default ?!

[netkas]

Thanks for fixing it Alex!

some update: it's greenish only on hdmi, it's ok on DP

[indepe]

tried 4.9.5 kernel

with radeon - same patch, same behaviour


with amdgpu:
the log - http://pastebin.com/NiTiWAYi
the patch - http://rgho.st/68s7Zq9V9

system doesn't freeze.

but everything is green.

in console, black became green, white is still white.
Xorg - everything is greenish, I can see colors - red, blue, green (in glxgear), but the darker the color the more greenish it is. the brighter the color the more magentish it is.

Are you meanwhile in contact with AMD and/or Mesa developers about the side-effects of your fix?

I don't know anything about this, so I can only contribute an un-educated guess: perhaps something else needs to be done when the second VBIOS is recognized, like allocating a second color translation table, and without that the two monitors "share" some data structures that are not designed to be shared.

patches for drm-next-4.11-wip
radeon: http://rgho.st/6xtTt6XDf
amdgpu: http://rgho.st/8HxfqWdFg

Please generate proper git patches, sign off on them, and send the patches to the amd-gfx mailing list.

[netkas]

If you use kernel from kernel.org or similar, they have minimal amount of new amdgpu code (see the diff column from kernel.org) , so code is UNFINISHED AS YOU SEE WITH DMESG. Use this for the amdgpu driver:
https://cgit.freedesktop.org/%7Eagd5...-next-4.11-wip
And this:
https://launchpad.net/~paulo-miguel-...mesa/+packages

already had mesa &stuff from that ppa installed.

I have tried the kernel form drm-next-4.11-wip.
There is absolutely no difference in results versus 4.9.5 (== exactly same results)


also, 4.9.5+amdgpu hardfreezed after some time too (it took much longer than with radeon driver)

when system freeze happens, display goes black as well.
