    Subject[PATCH v2 -mm 0/7] I/OAT: Add support for DCA - Direct Cache Access
    Date
    Andrew,

    Here's a new rev of the IOAT DCA patches that are currently in -mm. These
    patches include updates based on feedback on the first set, as well as a
    couple of other fixes we found internally. These were originally posted
    on 20-Jul-2007 - see http://marc.info/?l=linux-kernel&m=118489237427303&w=2

    The following series implements support for providers and clients of
    Direct Cache Access (DCA), a method for warming the cache in the correct
    CPU before needing data.

    ioat-new-device-ids.patch
    - add devices id's for newer Intel chipsets which support DMA and DCA
    ioat-rename-source-file.patch
    - prepare for adding new functionality
    ioat-dma-cleanups.patch
    - cleanup some code ugliness
    ioat-split-startup-code.patch
    - split the DMA support code from the PCI startup
    ioat-add-msi-msix-support.patch
    - add support for various interrupt handling schemes
    ioat-add-dca-support.patch
    - add the dca driver
    ioat-add-ioat-dca.patch
    - add DCA services to the ioatdma driver
