CVS commit: src/sys/dev/acpi

Module Name:    src
Committed By:   jruoho
Date:           Tue Aug 17 10:17:52 UTC 2010

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

Log Message:
Add support for the optional dynamic minimum (in terms of MHz) via _PDL.
Comparable to T-states, this gives effectively a window of available
performance states for passive cooling. An example:

Init:           max = 0, min = Pn.

                Time j.                         Time j + 1.
                -----------                     -----------
2000 MHz        P0      max                     P0
                P1                              P1      max
                P2                 ==>          P2
                P3                              P3      min
                P4                              P4
                P5      min                     P5
 500 Mhz        Pn                              Pn
                -----------                     -----------

Search:         repeat (i = P0; i <= P5)        repeat (i = P1; i <= P3)
