Comment 40 for bug 1776563

Hi all,

After a bit of testing the power management seems to be better but it is far away from perfect. I don't see any anomaly watching temperature sensors (instead of ath10k_hwmon-pci(?!??)) but my notebook is definitely warm if I hold it on my lap.
This is more better on win10, I don't know why.

mosomaci@pc:~$ sensors
k10temp-pci-00c3
Adapter: PCI adapter
Tdie: +55.0°C (high = +70.0°C)
Tctl: +55.0°C

amdgpu-pci-0100
Adapter: PCI adapter
vddgfx: +0.81 V
fan1: N/A
temp1: +50.0°C (crit = +104000.0°C, hyst = -273.1°C)
power1: 1.13 kW (cap = 28.00 W)

ath10k_hwmon-pci-0300
Adapter: PCI adapter
temp1: +91.0°C

amdgpu-pci-0400
Adapter: PCI adapter
vddgfx: N/A
vddnb: N/A
fan1: N/A
temp1: +55.0°C (crit = +80.0°C, hyst = +0.0°C)
power1: N/A

Could our APIC fix not a perfect solution for this problem? I know that the DSDT is totally broken:

I would be very thankful if anybody culd fix it.

IOMMU seems to be OK:

Otherwise this DSDT thing is a crap. We want to go to the Mars and make self-driving cars but we can not create a hardware configuration on which a 27 years old operating system can be installed.
