Added files:
sys/dev/acpica acpi_perf.c
Log:
Add the ACPI Performance states driver. This driver offers two or more
settings as exported via the ACPI _PSS method. OEMs use this interface
to encapsulate chipset or processor-specific methods (e.g., SpeedStep or
Powernow) and export their settings in a standard way. On systems that
have valid ACPI Performance states and a hardware-specific driver (e.g.,
ichss), acpi_perf(4) is preferred.
