Running CoreFreq with ARCH_PMC=UMC compiled build fails on 3500X #428

Closed emansom closed 1 year ago

emansom commented 1 year ago

Continuation of a bug discovered while debugging #422.

When trying to launch the daemon (_all pieces compiled with ARCH_PMC=UMC via locally modified PKGBUILD_) on a 3500X running on a X570 platform with various UEFI tweaks, it fails with the following message:

ewout@enthoo ~ % sudo systemctl status corefreqd.service

Is it possible to lower the Idle Limit with acpi_idle btw?

When checking with ryzen_monitor it does scale down to C6 all the way, so just wrong ACPI data the motherboard/UEFI is providing.

Thank you for the screenshots.

Apparently PMC appears not to be programmed the same on Zen architecture families. Reason I will keep this feature as a build option. There's not enough explanations in specifications.

No idea how to manage acpi_idle I prevent drivers from loading and make CoreFreq registers itself as the CPU-Idle handler. When done, I set kernel to put Core(s) in I/O wait. In kernel window, you will next change default C2 to C6 (technically: I/O read at base address + C6 index)

Registration can be requested from the Settings window. Just make sure mainstream drivers are blacklisted or unloaded before corefreqk.ko More in my Wiki
