Description bakarichard91 2018-07-17 01:31:33 UTC
Created attachment 277363 [details]
dmesg

Notebook: Acer A315-41G-*

4.* kernels start only using these parameters:
amdgpu.runpm=0 radeon.modeset=0 or compiled without VGA switcheroo.

lspci and dmesg attached

Even with these parameters significant heating occurs however this can be fixed by running "sudo echo OFF > /sys/kernel/debug/vgaswitcheroo/switch" command.

It would be the best if both of them worked correctly like on win10.

Please attach your full dmesg output from boot and `lspci -nn` output.
Comment 4 bakarichard91 2018-07-17 15:47:30 UTC
Hi,

Sorry for the duplication. It's worth to mention that APIC problems occured too which have been fixed using kernel parameters. (manual pci addressing)

possible fix

Does this patch fix the issue?
Comment 8 bakarichard91 2018-07-17 19:35:35 UTC
Hi, I've patched it and it loads perfectly without any additional parameters. I'm checking the temperature now.

Will this ever be merged to the "master"?

Thanks for the help. The support of linux is better than than support of any commerical product.

Assuming it fixes the issue, I'll go ahead and apply it to upstream and stable kernels.

This is apparently not a duplicate of that bug.  Similar symptoms, but different root cause.
Comment 11 bakarichard91 2018-07-17 20:58:09 UTC
I played Vietcong but the GPU hasn't switched, is that okay? Is there any way to monitor frequencies? However temperature seems to be OK now.
Comment 12 Alex Deucher 2018-07-18 14:17:25 UTC
If you are using X, you need to use xrandr to setup the dGPU for render offload.  E.g., see:
https://wiki.archlinux.org/index.php/PRIME
or similar pages.
Comment 13 bakarichard91 2018-07-18 15:00:27 UTC
That is clear, thanks.

Another topic, you seems to be competent to ask your opinion: what do you think why are my gpu and cpu core temps ~5-8C higher than on Windows 10. This is the best what open/free drivers can produce? Tlp is in use of course.
If I know well, my Acer notebook's power management is totally acpi controlled however the DSDT table was broken in Linux and I had to manually addressing two pci/apic controllers to even start the kernel.
Do you have any suggestion what I should do not to be my legs burnt.
Thanks.
Comment 14 Alex Deucher 2018-07-18 15:18:18 UTC
On the GPU side, we are working on enabling gfxoff and stutter mode which should save some additional power.  They are not enabled by default yet, but should be in the near future.  For the platform side (CPU, FCH, etc.), you may want to run something like powertop and see what can be done to save power on things like USB, SATA, etc.
Comment 15 bakarichard91 2018-07-28 17:48:20 UTC
Hi Alex, kernel 4.18rc6 works perfectly. This can be closed I think. Thanks again.
(Power problems were fixed with patching DSDT/SSDT tables)

Hi Richard,

In an attempt to understand the problem better, could you attach these two files:

sudo acpidump > acpidump.txt
sudo lspci -nnvvvxxxx > lspci-nnvvvxxxx.txt
