From 0ac3c571315a53c14d2733564f14ebdb911fe903 Mon Sep 17 00:00:00 2001 From: Zhao Yakui Date: Thu, 15 Nov 2007 17:05:46 +0800 Subject: [PATCH] ACPI: Get throttling info from BIOS only after evaluating _PDC Previously _PDC was evaluated later, and thus we'd not get the chance to tell the BIOS that we can suport FixedHW registers (MSRs) and the BIOS would always ask us to use System I/O access for throttling.
