Subject[PATCH 0/2] x86/tsc: split X86_FEATURE_TSC_RELIABLE into two
Date
This patch series split X86_FEATURE_TSC_RELIABLE into two separate
flags: X86_FEATURE_TSC_RELIABLE and X86_FEATURE_TSC_KNOWN_FREQ.
This change allows us to redefine TSC features at fine granularity.
This is driven by certain Intel processors/SoCs with frequency-known
TSC so the whole calibration stuff should be skipped.

Bin Gao (2):
x86/tsc: add X86_FEATURE_TSC_KNOWN_FREQ flag
x86: use KNOWN_FREQ and RELIABLE TSC flags on certain processors/SoCs
