Functions§

  • bus_freq_hz
    Returns the Bus frequency in Hz, based on reading Intel-specific cpuids, or None if the frequency can’t be determined from cpuids.
  • fake_tsc_frequency_cpuid
    Given the tsc frequency in Hz and the bus frequency in Hz, return a fake version of cpuid leaf 0x15.
  • tsc_freq_hz
    Returns the TSC frequency in Hz, based on reading Intel-specific cpuids, or None if the frequency can’t be determined from cpuids.
  • tsc_frequency_cpuid
    Gets the TSC frequency for cpuid leaf 0x15 from the existing leaves 0x15 and 0x16.
