[PATCH v2 0/6] ATS capability support for Intel IOMMU

From: Yu Zhao
Date: Sat Jan 17 2009 - 23:21:35 EST


This patch series implements Address Translation Service support for
the Intel IOMMU. ATS makes the PCI Endpoint be able to request the
DMA address translation from the IOMMU and cache the translation in
the Endpoint, thus alleviate IOMMU pressure and improve the hardware
performance in the I/O virtualization environment.

Changelog: v1 -> v2
added 'static' prefix to a local LIST_HEAD (Andrew Morton)
