Message-ID: <1323092077-25501-1-git-send-email-joerg.roedel@amd.com> Date: Mon, 5 Dec 2011 14:34:15 +0100 From: Joerg Roedel <joerg.roedel@....com> To: <iommu@...ts.linux-foundation.org> CC: <linux-kernel@...r.kernel.org> Subject: [PATCH 0/22] Initial AMD IOMMUv2 support Hi, here is a patch-set that adds initial support for the AMD IOMMU version 2 to the Linux kernel. The main feature of the new IOMMU version is support for DMA demand-paging and multiple DMA address spaces per device. The patch-set consists of 2 parts. Patches 1-16 implement the hardware access functions to setup and manage the IOMMUv2 functionality of the hardware. Patches 17-22 implement a seperate module which makes use these functions to implement a page-fault handler for devices which can be used by real device drivers. Any feedback appreciated.
