It's already backported to 5.10, just after 5.10.46 was released:
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=linux-5.10.y&id=fea853aca3210c21dfcf07bb82d501b7fd1900a7

Just found out the reverted commit was introduced just before the 5.10.46 tag
was created, which should mean that any version before 5.10.46 should NOT
have this problem. The version uploaded to the Debian archive before that
was 5.10.40-1, which in my case was linux-image-5.10.0-7-amd64.
I no longer had that installed, so added the following line to /e/a/sources.list:
deb [check-valid-until=no] https://snapshot.debian.org/archive/debian/20210529T204006Z/ sid main
Installed linux-image-5.10.0-7-amd64 and rebooted into that ...

So running a kernel != 5.10.46 does not have this problem :)

I just found out it's 2 commits that should be reverted
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=linux-5.10.y&id=1bd81429d53ded4e111616c755a64fad80849354

The first one I saved (and attached) as 'fix-bug991453-part1.patch' and the
second one as 'fix-bug991453-part1.patch'
Then I followed step 4.2.1 and 4.2.2 of the kernel handbook:
https://kernel-team.pages.debian.net/kernel-handbook/ch-common-tasks.html#s-common-official
That resulted in 'linux-image-5.10.0-8-amd64-unsigned_5.10.46-2a~test_amd64.deb'
which I then installed on my system and rebooted into that.

0.03G / 1.63G Shader Clock 1.78%
These are the same 'scores' as I had with the 5.10.0-7-amd64 kernel.
So applying the mentioned/attached patches on top of the current kernel
as available in Debian Testing/Bullseye and Sid, fixes the problem.
In the last year I've spend considerable time to bring down my energy
usage/needs and I never expected that (reverting) 2 kernel commits
would save me 67W (continuously), so thank you very much piorunz for
bringing this to my attention.
I normally have a quiet system and noticed it often wasn't quiet lately;
I blame(d) 'baloo' (file indexing) for that, but it turns out it was mostly
my GPU running at 100% all the time.
As it looks like a lot of users with AMD GPUs are affected and the
considerable energy wasted because of it (Climate Change),
I really hope/urge that these 2 patches/reverts are applied before Bullseye
gets released.
Cheers,
Diederik
