CVS commit: src/sys/dev/acpi

Module Name:    src
Committed By:   jruoho
Date:           Mon Aug 16 20:07:57 UTC 2010

Modified Files:
        src/sys/dev/acpi: acpi_cpu.c acpi_cpu_pstate.c

Log Message:
Two changes:

  1.    Initialize P-states properly to P0. It is processor-specific
        what value we might get without initialization. (Some AMD CPUs
        have even specific registers for the state after cold reset.)

  2.    Following design notes for Windows, set the lowest-power P-state
        upon suspend and restore the saved state after resume.
