NO! I run with no change to ACPI either in BIOS nor Boot Switch.
Looking at ANY AMD X_64 CPU you can see the boot log for yourself!
We currently have both neither a CPU thermal ladder and no Kernel throttling.
As such the CPU runs at max clock all the time and the GPU follows the CPU's
lead and given a warm ambient temp a full installation(reason above) can and
will either invoke BIOS overheat and a shut-down and/or completely cook both
CPU/GPU
The bugger in the middle of this is AMD's Cool 'n Quiet!
When Enabled the CPU always starts at the least clock speed and slowly upshifts
its clock speed speed when under pressure. The reason this has BIOS default of
Disabled is that the upshifts in clock speed takes for ever to occur and makes
the PC perform like a slug.
The BIOS default is thankfully DISABLED.
Cool 'N Quiet is AMD's BIOS control over CPU clock speed and it can and does
slow the CPU/GPU clock when thermal sensors get far too hot!
The issue is that we have is
We currently have both neither a CPU thermal ladder and no Kernel throttling of
the CPU/GPU.
EVERY boot log of an AMD X_64 CPU will show that there is NO thermal
Monitoring because of ?? and the Kernel has no throttling because of ?
We have a Widget that can report thermal monitoring so why cant out boot
process monitor the CPU/GPU temp and take action when required?
Attached are images that show that KDE cannot use Power Control and has No
ability to use power control.
We need a CPU Thermal Ladder for AMD X_64 CPU's and the ability to slow its
clock via either Kernel or Thermal Ladder or ???
Thanks for taking this seriously, everyone else in development gave up in 2008
and all the users who have reported any type of CPU being cooked have also
given up...:-)
