|Subject:||[PATCH v3 -mm 0/7] I/OAT: Add support for DCA - Direct Cache Access|
|Date:||Wed, 29 Aug 2007 12:01:29 -0700|
Andrew, Here's rev 3 of the IOAT DCA patches that are currently in -mm. These patches include updates based on feedback on the previous sets, 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&... They apply to 2.6.23-rc4 and are targeted for merge into 2.6.24. 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 b/drivers/Kconfig | 2 b/drivers/Makefile | 1 b/drivers/dca/Kconfig | 7 b/drivers/dca/Makefile | 2 b/drivers/dca/dca-core.c | 200 +++++++ b/drivers/dca/dca-sysfs.c | 88 +++ b/drivers/dma/Kconfig | 60 +- b/drivers/dma/Makefile | 1 b/drivers/dma/ioat.c | 211 ++++++++ b/drivers/dma/ioat_dca.c | 263 ++++++++++ b/drivers/dma/ioat_dma.c | 960 ++++++++++++++++++++++++++++++++++++++ b/drivers/dma/ioatdma.h | 35 + b/drivers/dma/ioatdma_hw.h | 2 b/drivers/dma/ioatdma_registers.h | 6 b/include/asm-i386/cpufeature.h | 1 b/include/linux/bitops.h | 6 b/include/linux/dca.h | 47 + b/include/linux/pci_ids.h | 2 drivers/dma/ioatdma.c | 817 -------------------------------- 19 files changed, 1861 insertions(+), 850 deletions(-) Thanks, sln -- ====================================================================== Mr. Shannon Nelson LAN Access Division, Intel Corp.
