From 5fde244d39b88625ac578d83e6625138714de031 Mon Sep 17 00:00:00 2001 From: Shaohua Li Date: Wed, 23 Jul 2008 10:32:24 +0800 Subject: PCI: disable ASPM per ACPI FADT setting The ACPI FADT table includes an ASPM control bit. If the bit is set, do not enable ASPM since it may indicate that the platform doesn't actually support the feature.
