Message-ID: <4A0C17BB.4010300@solarflare.com> Date: Thu, 14 May 2009 14:08:11 +0100 From: Neil Turton <nturton@...arflare.com> To: "Roedel, Joerg" <Joerg.Roedel@....com> CC: Linux Kernel <linux-kernel@...r.kernel.org>, iommu@...ts.linux-foundation.org Subject: [PATCH] Fixed the handling of device aliases in the AMD IOMMU driver. The devid parameter to set_dev_entry_from_acpi is the requester ID rather than the device ID since it is used to index the IOMMU device table. The handling of IVHD_DEV_ALIAS used to pass the device ID. This patch fixes it to pass the requester ID.
