Few questions - AMDGPU - VALVe - GCN 1.0

[Amarildo]

So someone on reddit told me they figured out how to not make it hang: https://github.com/flto/linux/commit...4b606d4048304c
direct link to patch: https://github.com/flto/linux/commit...4048304c.patch

I can confirm, it works. csgo and xonotic work, bioshock crashes it:

 [TTM] Failed to expire sync object before buffer eviction

More importantly: dpm doesn't really work. It has bad performance (same as booting with amdgpu.dpm=0) and

echo high > /sys/class/drm/card1/device/power_dpm_force_performance_level

hangs the rendering completely and further hangs the whole system when trying to do anything else with the GPU.

But: It's progress and it looks like we can soon expect something working.

I'm using this patch for DPM: https://raw.githubusercontent.com/am...ster/dpm.patch
You could adjust it to the amdgpu path on your source dir and see if it works for you.

Am, the bug report mentioned in the code says

That tree is using the same code power management as radeon, just ported to amdgpu.

and on radeon dpm is working fine. So far it seems to be broken for everyone, so it may be a more basic problem.
