Alexander Motin 326a8d3e08 hwpmc: Skip GLOBAL_CTRL updates on stop_pmc(). ... After we wipe PMC configuration, including its local enable bit(s), we don't really care about its global enable bit. Global enable bits now may only be cleared by interrupt handler in case of error (sample buffer overflow). Being set is actually a reset default for them. This saves one WRMSR per process-scope PMC per context switch, that is clearly visible in profiles. MFC after: 1 month		2022-06-02 18:35:55 -04:00
