From 4db8699bcfa8faddb5727b1cb010a4d9b8a42e8c Mon Sep 17 00:00:00 2001 From: Venkatesh Pallipadi Date: Fri, 29 Jul 2005 16:15:00 -0700 Subject: [IA64] Add ACPI based P-state support Patch to support P-state transitions on ia64. This driver is based on ACPI, and uses the ACPI processor driver interface to find out the P-state support information for the processor. This driver plugs into generic cpufreq infrastructure. Once this driver is loaded successfully, ondemand/userspace governor can be used to change the CPU frequency dynamically based on load or on request from userspace process.
