            Bug ID: 210683
           Summary: Nasty gpu powersave regression Navi14
           Product: Drivers
           Version: 2.5
    Kernel Version: 5.10-rc7
          Hardware: All
                OS: Linux
              Tree: Mainline
            Status: NEW
          Severity: high
          Priority: P1
         Component: Video(DRI - non Intel)
          Assignee: drivers_video-dri@kernel-bugs.osdl.org
          Reporter: eutychios23@gmail.com
        Regression: No

Regression compared to kernel 5.19, the gpu idles constantly from 5W-6W to
15W-16W after upgrading to kernel 5.10rc7 resulting in higher temps at idle

Just tested kernel 5.10 stable and idle powersave is still broken on the gpu
compared to kernel 5.9

vddgfx also plays between 6.00mv-700mv compared to a steady 6.00 mv in kernel
5.9 at idle

Please attach your dmesg output.  Can you bisect?

Created attachment 294239
  --> https://bugzilla.kernel.org/attachment.cgi?id=294239&action=edit
dmesg outputs for 5.9.14 and 5.10.1.

I can reproduce the issue on the RX 6800 (Navi 21 XL).

I use Radeontop to inspect the memory/GPU clock of my GPU.

When using Linux 5.9.14:
- In both KDE Plasma and tty2, Memory Clock hovers at around 100MHz.
- GPU Power reported by lm_sensors is around 5-7W.

When using Linux 5.10.1:
- In tty2, Memory Clock hovers at around 100MHz and GPU Power reported by
lm_sensors is around 5-7W.
- In KDE Plasma, Memory Clock is usually around 1GHz (100%), although it can be
down to ~470MHz, and GPU Power reported by lm_sensors is around 30W.
- Disconnecting one of my two monitors does not change the memory clock.

I am trying to bisect the commit, but many revisions seem to give a blank
screen or the amdgpu module is not loaded. (I suspect I am not building the
kernel properly)

Tested linux-firmware versions: 20201120.bc9cd0b, 20201218.646f159

git bisect for Navi 21.

Not sure if I am doing is properly, but I performed a git bisect between 5.9
and 5.10 on drivers/gpu/drm/amd.

Note that none of the supposedly "good" commits actually fixed the issue. I
just mark them as "good" because those commits either cannot modeset to my
monitor's resolution, or the kernel fails to write certain registers to my GPU
and causes my display lose signal and go to standby. So technically the "first
bad commit" is just the first commit that I can boot into SDDM/KDE and can also
reproduce the issue.

Please let me know if there are anything else I can help with. I have a spare
Vega 64 (Vega 10) card lying around, but it has its own memory clock issues as
far as I remember =/

This seems to affect APUs as well. I can reproduce the issue on Raven (3500U).

I can confirm this with an RX 5700 XT.

GPU-power and temperatures with running fans @1100 rpm:

with kernel 5.9.14 during idle = 10 -11 W, temps around 32-35 deg C
with kernel 5.10.1 and 5.10.2 during idle = 35 W, temps around 42-45 deg C

--- Comment #9 from Andreas Prittwitz (m4ng4n@gmx.de) ---
I have done some addtional testing.
I am running an up to date openSUSE Tumleweed with KDE Plasma.
My monitor is capable of running at 60, 100, 120 and 144 Hz refresh rate.

For some reason unknown to me it was set to 60 Hz after the last update.
With this setting it idled at 35 W instead of the usual 11 W.
Also the memory/GPU frequencies come down to what they used to and where they
should be.

After setting it back to 144 Hz, wattage at idle came back down to 11 W.
Setting it back to 60 Hz refresh rate lets the wattage come back up to 35 W.
This is reproducible any time.

Setting it to 100 and 120 Hz resepectively lets the graphics card also idle at
11W.

It seems, at least on my system, that this bug only affects me, when the
monitor is set to 60 Hz refresh rate.
