This is a note to let you know that I have just added a patch titled iommu/amd: Fix interrupt remapping for aliased devices to the linux-3.11.y-queue branch of the 3.11.y.z extended stable tree which can be found at: http://kernel.ubuntu.com/git?p=ubuntu/linux.git;a=shortlog;h=refs/heads/linux-3.11.y-queue If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.11.y.z tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Luis ------ From ae362474623d0dfe4826f49151b9c8cc18e1cb29 Mon Sep 17 00:00:00 2001 From: Alex Williamson <alex.williamson@redhat.com> Date: Tue, 22 Apr 2014 10:08:40 -0600 Subject: iommu/amd: Fix interrupt remapping for aliased devices commit e028a9e6b8a637af09ac4114083280df4a7045f1 upstream. An apparent cut and paste error prevents the correct flags from being set on the alias device resulting in MSI on conventional PCI devices failing to work. This also produces error events from the IOMMU like: AMD-Vi: Event logged [INVALID_DEVICE_REQUEST device=00:14.4 address=0x000000fdf8000000 flags=0x0a00] Where 14.4 is a PCIe-to-PCI bridge with a device behind it trying to use MSI interrupts.
