| |
Hi everybody!
System: AOpen i915GMm-HFS motherboard, kernel 2.6.16 CPU: Intel(R) Pentium(R) M processor 1.86GHz stepping 08
During startup a BogoMips value of 3730.21 is calculated. That should be the correct value for the cpu running at full speed. But:
"cat /proc/cpuinfo" on the idle system displays the correct cpu speed, but a wrong bogomips value:
cpu MHz : 800.000 bogomips : 3730.21
"cat /proc/cpuinfo" on the busy system displays the correct cpu speed too, but again a wrong bogomips value:
cpu MHz : 1867.000 bogomips : 8705.38
The relevant snippets from .config:
CONFIG_X86_PC=y CONFIG_MPENTIUMM=y
CONFIG_CPU_FREQ=y CONFIG_CPU_FREQ_TABLE=y CONFIG_CPU_FREQ_DEBUG=y CONFIG_CPU_FREQ_STAT=y CONFIG_CPU_FREQ_STAT_DETAILS=y CONFIG_CPU_FREQ_DEFAULT_GOV_PERFORMANCE=y CONFIG_CPU_FREQ_GOV_PERFORMANCE=y CONFIG_CPU_FREQ_GOV_POWERSAVE=y CONFIG_CPU_FREQ_GOV_USERSPACE=y CONFIG_CPU_FREQ_GOV_ONDEMAND=y CONFIG_CPU_FREQ_GOV_CONSERVATIVE=y
CONFIG_X86_ACPI_CPUFREQ=y CONFIG_X86_SPEEDSTEP_CENTRINO=y CONFIG_X86_SPEEDSTEP_CENTRINO_ACPI=y
cu, knut
