Performance states

Performance states

[Dumitru Ciobarcianu]

Hello,

While trying to test 2.6-test1 kernel I found that I don't have anymore
the performance management for my CPU.

Is is something I forgot to enable (triplechecked first....) ?

>From 2.4+acpi patch dmesg: 
ACPI: Processor [CPU0] (supports C1 C2 C3, 2 performance states)

>From 2.6-test1 dmesg:

Where did the performance states went ? :)

They went to CONFIG_CPU_FREQ and CONFIG_X86_ACPI_CPUFREQ. However, there are
a few bugs in the X86_ACPI_CPUFREQ driver which I'll try to solve the next
few days.
