Kernel 5.6.4 upgrade AMDGPU discrete card running all the time.

On my Dell Laptop ,after upgrading to 5.6.4 kernel, discrete card is running all the time, with Radeon drivers it's ok, it happens only with AMDGPU.

this are making laptop working more hot than normal..  usually i use PRIME for activate the discrete card for some applications... but now.. it's on all the time.

this is a bug in the kernel with AMDGPU driver or something? anyone are experiencing this?

 $ lspci -k 
01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Chelsea LP [Radeon HD 7730M]
	Subsystem: Dell Chelsea LP [Radeon HD 7730M]
	Kernel driver in use: amdgpu
	Kernel modules: radeon, amdgpu

$sensors

Re: Kernel 5.6.4 upgrade AMDGPU discrete card running all the time.

Your card appears to be GCN 1 and may very well be a special design for dell.

Try linux-lts kernel or an older 5.6.x kernel to see if changes in amdgpu kernel driver caused this.

Hi, running LTS 5.4.32-1 it seems normal as it should, current kernel really broke AMDGPU driver on my dell..

Then I suggest you keep both linux and linux-lts installed and setup your bootloader to be able to switch between them.

AMDGPU was doing very well here, until it gets fixed, I think I'll stay with Radeon., These are stable too btw

thanks man.

I can confirm with the same issue. I'm currently using a 5.6.3 kernel.

Re: Kernel 5.6.4 upgrade AMDGPU discrete card running all the time.

Is the issue present under 5.7-rc7?  Is there an upstream bug report?
Edit:
If the issue was introduced between 5.6.3 and 5.6.4 has a bisection to locate the cause been attempted?
https://cdn.kernel.org/pub/linux/kernel … eLog-5.6.4 not seeing any amdgpu changes from 5.6.3

Well, since then I am now running the stable 5.6.15 .. the problem with AMDGPU drivers still persists as I reported before.

I have not tested with mainline... only with stable and LTS .. and as I said earlier, LTS is working fine with AMDGPU.

You can report your issue to upstream using https://gitlab.freedesktop.org/drm/amd/-/issues see also https://www.kernel.org/doc/html/latest/ … -bugs.html

https://gitlab.freedesktop.org/drm/amd/-/issues/1157 if this is your report the issue was introduced between 5.4 and 5.6 not between 5.6.3 and 5.6.4?

Re: Kernel 5.6.4 upgrade AMDGPU discrete card running all the time.

I noticed this happening in 5.6.4. but not immediately after the update, I really don't know when EXACTLY amdgpu started to behave like that, because I hadn't noticed it before.

then I ran LTS and it was ok .. so I assume it is between 5.4 and 5.6 ..
