According to Intel 64 and IA-32 Architectures SDM, Volume 3,
Chapter 14.2, "Software needs to exercise care to avoid delays
between the two RDMSRs (for example interrupts)".
So, disable interrupts during reading MSRs IA32_APERF and IA32_MPERF.
Since the TSC is also takes place in the calculation
According to Intel 64 and IA-32 Architectures SDM, Volume 3,
Chapter 14.2, Software needs to exercise care to avoid delays
between the two RDMSRs (for example interrupts).
So, disable interrupts during reading MSRs IA32_APERF and IA32_MPERF.
