errors in dmesg
If xorg is started while screens are off or disconnected, ugly messages get
printed into dmesg and the screens do not get activated if they are then turned
on. Also seems to kill x11vnc if that was started.

Bug ID: 108573
Summary: Cannot set pstate values with under-voltage values for
Vega M
Product: DRI
Version: unspecified
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: DRM/AMDgpu
Assignee: dri-devel(a)lists.freedesktop.org
Reporter: rstrube(a)gmail.com
There are some folks on the Windows side of the fence that have had great
success under-volting their Vega M chips to improve thermals (and because TDP
is shared between the CPU and GPU on Kaby Lake G, also their overall
performance).
Following information from the amdgpu kernel documentation I applied the
following kernel boot parameters:
amdgpu.runpm=0 amdgpu.ppfeaturemask=0xffffffff
Note: I needed the runpm=0 so that the Vega M is active at all times, otherwise
it powers down and I'm unable to make any changes to the pstates using the
sysfs API.
Then doing the following I was able to see the current pstates:
cat /sys/bus/pci/drivers/amdgpu/0000:01:00.0/pp_od_clk_voltage
OD_SCLK:
0: 225MHz 750mV
1: 400MHz 750mV
2: 535MHz 750mV
3: 715MHz 750mV
4: 850MHz 750mV
5: 960MHz 750mV
6: 985MHz 750mV
7: 1011MHz 750mV
OD_MCLK:
0: 300MHz 750mV
1: 500MHz 750mV
2: 700MHz 750mV
OD_RANGE:
SCLK: 225MHz 1011MHz
MCLK: 300MHz 700MHz
VDDC: 750mV 750mV
Then this to support updating the pstates:
echo "manual" >
/sys/bus/pci/drivers/amdgpu/0000:01:00.0/power_dpm_force_performance_level
Then I could push in new pstates values, provided the voltage was *exactly*
750mV. I could set a higher clock speed for a pstate, but I was unable to make
any changes to the voltage.
echo "s 0 226 750" > /sys/bus/pci/drivers/amdgpu/0000:01:00.0/pp_od_clk_voltage
works and increases the MHz from 225 -> 226 for pstate 0, but
echo "s 0 226 749" > /sys/bus/pci/drivers/amdgpu/0000:01:00.0/pp_od_clk_voltage
-bash: echo: write error: Invalid argument
Checking dmesg I see that the voltage range is constrained between 750 and 750.
[ 4362.487021] amdgpu: [powerplay] OD voltage is out of range [750 - 750] mV
Would it be possible to add support for under-volting Vega M using the sysfs
API?
I also noticed that it's not possible to set any pstate higher than 1011 MHz,
perhaps that's a harder sell, but it might also be nice to be able to overclock
the Vega M a little!
P.S. I tried finding these values in the kernel source code, but I was
extremely confused about the way they are defined. I figured worse case
scenario I could manually modify these limits and recompile the kernel.
Thanks!
Rob

Radeon R5 M330 gpu hungs when dpm enabled and running gpu intensive programs
with DRI_PRIME=1. If amdgpu.dpm disabled no freezes happens, but gpu always on
same clock speed. This happens on every linux ditro I tried. Oldest kernel I
tryed was 4.9, now I'm using amd-staging-drm-next kernel and still have
problem.
Also this happens with radeon module with radeon.dpm=1 but just before hung lot
of texture/shader artifacts appears on screen

In SuperTuxKart, upon loading the first track of the story mode, the display
freezes. The GPU resets but when it comes back everything is messed up and it
keeps resetting continuously.
I'm using latest kernel 3.19-rc3 with the "drm/radeon: fix VM flush..." patches
(also tested without it), latest mesa from git, latest drm from git.
I'll see a journald dump outputs something interesting.

picture of the corrupted screen
I'm using Ubuntu 18.04.1 and amdgpu 18.40-676022.
After resume to RAM, my screen was corrupted, showing big black horizontal
bands: I attach a picture to show better.
After moving the mouse on the bands, the windows were refreshed and they went
back to normality.
I also attach a bunch of logs as explained here:

- since 4.18, the hdmi output says "12 bit"
- since 4.18.8 there's no video output !!
