the default is -1 (auto). Power management has always been enabled by
default on CI. the option is mainly there to disable power management
(amdgpu.dpm=0). Since there are two implementations for CI (the older
one ported from radeon and the newer powerplay one), explicitly
setting it to 1 was us
OK, thanks. Although for reference, if DPM is now enabled by default I
would have expected amdgpu.dpm=1 to be a no-op rather than cause a black
screen and an oops... ;-).
Cheers,

Yes, all 4.19.x kernels have been fine without the amdgpu.dpm=1 kernel
parameter. In fact, this is how I am running my kernel right now. With the
4.18.x series I did specify amdgpu.dpm=1 explicitly on the GRUB2 command
line, and I inherited this setting when I migrated to 4.19.

Does it work without amdgpu.dpm=1 on your kernel command line? You
don't need to specify it, it;s enabled by default. The default dpm
implementation changed so specifying dpm=1 will change the dpm
implementation used by the driver.

I can't reproduce this. Can you bisect?

Hi,
I'm still unable to enable DPM with my R7 360, AMDGPU driver, Linux 4.19.7
kernel. Dmesg log is attached, showing that it is correctly using PCIE gen2
speeds.

Hi, thanks for the reply.
That patch doesn't solve my issue, although it does mean that the DRM layer
no longer tries to enable "gen 3" PCIE link speeds.
I have attached the dmesg output for a stock 4.19.4 kernel that also has
your patch applied.

Hi,
I have recently tried to use dpm=1 with the amdgpu driver for the 4.19.x
kernel, but unfortunately the screen just went black. This is a regression
from the 4.18.x kernel.
I have attached the full dmesg log, but the relevant section look to be:
[8.958679] WARNING: CPU: 0 PID: 320 at driv
10 matches
