Hi, Marc
thanks for your info. From the above info there are two sides about your
system.
1. CPUfreq module can' work.
What Rui and Len said is very right. From the acpidump we can know that
c-states and p-states can't be supported on your system.
Scope (_PR)
{
Processor (CPU0, 0x00, 0x00001010, 0x06) {}
Processor (CPU1, 0x01, 0x00001010, 0x06) {}
Processor (CPU2, 0x02, 0x00001010, 0x06) {}
Processor (CPU3, 0x03, 0x00001010, 0x06) {}
}
There are no definitions of C-states(CST,CSD) and P-states(PSS).
In the initialization of cpufreq module the cpufreq will check whether P-state
is supported. If the check fails , the cpufreq can't be loaded. Unfortunately
there is no definiton of P-states, so the cpufreq module can't be loaded.
Will you please update the bios ? Maybe the latest bios has solved this
problem.
2. AE_NOT_FOUND message (this error message should be ignored.)
Four cpus are defined in the DSDT table. And Two cpus are defined and
eanbled in the APIC table.
In the initialization the system will check whether the cpu defined in DSDT
table exists. If it exists it will attch the cpu to the driver of
acpi_process_driver.
There are two steps to check whether CPU exists.
A. check whether the cpu is defined and enabled in the APIC table.
B. check whether the cpu is hotplugged using the _STA method of CPU, which
is defined in the DSDT table.
Because there is no detailed info about CPU in the DSDT table, the system
will report the error message of AE_NOT_FOUND.
Please ignore the info. It has no effect on your system.
