Andreas Herrmann 9566e91d49 x86: fix detection of CONSTANT_TSC bit for AMD CPUs ... Commits - c52f61fcbdb2aa84f0e4d831ef07f375e6b99b2c (x86: allow TSC clock source on AMD Fam10h and some cleanup) - e30436f05d456efaff77611e4494f607b14c2782 (x86: move X86_FEATURE_CONSTANT_TSC into early cpu feature detection) are supposed to fix the detection of contant TSC for AMD CPUs. Unfortunately on x86_64 it does still not work with current x86/mm. For a Phenom I still get: ... TSC calibrated against PM_TIMER Marking TSC unstable due to TSCs unsynchronized time.c: Detected 2288.366 MHz processor. ... We have to set c->x86_power in early_identify_cpu to properly detect the CONSTANT_TSC bit in early_init_amd. Attached patch fixes this issue. Following the relevant boot messages when the fix is used: ... TSC calibrated against PM_TIMER time.c: Detected 2288.279 MHz processor. ... Initializing CPU#1 ... checking TSC synchronization [CPU#0 -> CPU#1]: passed. ... Initializing CPU#2 ... checking TSC synchronization [CPU#0 -> CPU#2]: passed. ... Booting processor 3/4 APIC 0x3 ... checking TSC synchronization [CPU#0 -> CPU#3]: passed. Brought up 4 CPUs ... Patch is against x86/mm (v2.6.24-rc8-672-ga9f7faa). Please apply. Set c->x86_power in early_identify_cpu. This ensures that X86_FEATURE_CONSTANT_TSC can properly be set in early_init_amd.
