| |
Hi-
By BIOS (1.2.3 on a Dell XPS 13 9350) seems to want to enable C1E auto-promotion (ugh!), which results in this difference across suspend/resume according to turbostat:
-cpu3: MSR_IA32_POWER_CTL: 0x0024005d (C1E auto-promotion: DISabled) +cpu3: MSR_IA32_POWER_CTL: 0x0024005f (C1E auto-promotion: ENabled)
Should intel_idle learn to re-disable idle promotion on resume?
