From 8ab4abbee6df256e7afb7e90a3332aed7453d538 Mon Sep 17 00:00:00 2001 From: Alex Williamson Date: Sat, 5 Jul 2014 15:26:52 -0600 Subject: [PATCH] PCI: Add bridge DMA alias quirk for Intel 82801 bridge This bridge sometimes shows up as a root complex device and sometimes as a discrete PCIe-to-PCI bridge. Testing indicates that in the latter case, we need to enable the PCIe bridge DMA alias quirk.
