log for dce_mi_free_dmif line:636
If my machine with a Vega 64 idles for long enough for the GPU to be "=
put to
sleep" to save power, it won't wake up. If given inputs, The monitors =
get wake
up, but only show black, indicating that something is happening.
Looking at kernel logs, this always starts with:
[drm:generic_reg_wait [amdgpu]] *ERROR* REG_WAIT timeout 10us * 3500 tries -
dce_mi_free_dmif line:636
(full log attached separately)
While trying to "wake up" and/or if I try to switch to a differen=
t TTY, another
error pops up for every attempt, but the opening line is now:
[drm:generic_reg_wait [amdgpu]] *ERROR* REG_WAIT timeout 10us * 6000 tries -
dce_mi_allocate_dmif line:599
(full log also attached separately)
I experience this problem with every kernel version I tried from 4.16.x to =
and
including 4.18.7
Haven't tried earlier versions and not sure which kernel to try to build in
order to test the *latest* amdgpu code. Could test the latest amdgpu code i=
f I
could get pointed to it.
As a workaround, I have a tiny video on mpv running on infinite loop in the
background using an opengl output, to prevent the GPU from trying to sleep.=
