"Advanced option-> CPU option -> PSS disable/enable"is the switch option of CPPC. Disabling *PSS* option will make Win11 OS switch to generic ACPI processor = pm management. Back to this issue, somehow ASUS has enabled CPPC support in bios,as it sho= wes "PSS ENABLED" in this video.=20 https://bugzilla.kernel.org/attachment.cgi?id=3D306662 But the key CPUID bit of CPPC func enablement still is not written "1" in t= his new version BIOS, besides, the dmesg log shows the _cpc obj in the ACPI ta= ble is null, "ACPI CPPC: _CPC in PCC is not supported". So the conclusion is, CPPC func is enabled in this new version BIOS and Win= OS is using it, but it doesn't support Linux OS. Maybe ASUS didn't put too much notice to the user case on linux os? --=20 You may reply to this email to add a comment. You are receiving this mail because: You are the assignee for the bug.=
