[linux-yocto] [PATCH 1/2] x86 tsc: enumerate SKL cpu_khz and tsc_khz via CPUID

2016-06-30 Thread Saul Wold
From: Len Brown Skylake CPU base-frequency and TSC frequency may differ by up to 2%. Enumerate CPU and TSC frequencies separately, allowing cpu_khz and tsc_khz to differ. The existing CPU frequency calibration mechanism is unchanged. However, CPUID extensions are preferred, when available. CPU
