From b01ac7e26453677318776885d4ab870f59553ae6 Mon Sep 17 00:00:00 2001 From: Patrick Rudolph Date: Sun, 26 Jul 2020 14:23:37 +0200 Subject: cpu/intel/common: Fill cpu voltage in SMBIOS tables Introduce a weak function to let the platform code provide the processor voltage in 100mV units. Implement the function on Intel platforms using the MSR_PERF_STATUS msr. On other platforms the processor voltage still reads as unknown. Tested on Intel CFL. The CPU voltage is correctly advertised.
