It is a soft IP core, which provides high-bandwidth direct memory access between memory and AXI4-Stream video type target peripherals including peripherals which support AXI4-Stream Video Protocol. The core provides efficient two dimensional DMA operations with independent asynchronous read and write channel operation. For more information on the IP, please refer to http://www.xilinx.com/support/documentation/ip_documentation/axi_vdma/v6_1/pg020_axi_vdma.pdf This patch also provides a test client, which assumes read and write channels of the core are configured in a back-to-back connection. It transfers data on the write channel, read and verify the data on the read channel. Use cases: ++++++++++ 1. Xilinx Video Targeted Reference design http://www.wiki.xilinx.com/Zynq+Base+TRD+14.5 2. Common Display Framework http://events.linuxfoundation.org/sites/events/files/slides/20131024-elce.pdf Regards, Srikanth Changes in v4: - Rebased on v3.14.0-rc5 - Reverted the changes that were done for the earlier patch series, 1/3 - 'Support multiple interleaved frames with non-contiguous memory' as suggested by Jaswinder, Thanks. Changes in v3: - Created a separate patch for the DT binding documentation as suggested by Vinod, Thanks. - Added support for interleaved frames with non-contiguous memory as suggested by Lars, Thanks. - Rebased on v3.14.0-rc2 Srikanth Thokala (2): dma: Add Xilinx Video DMA DT Binding Documentation dma: Add Xilinx AXI Video Direct Memory Access Engine driver support .../devicetree/bindings/dma/xilinx/xilinx_vdma.txt | 75 ++ drivers/dma/Kconfig | 14 + drivers/dma/Makefile | 1 + drivers/dma/xilinx/Makefile | 1 + drivers/dma/xilinx/xilinx_vdma.c | 1390 ++++++++++++++++++++ include/linux/amba/xilinx_dma.h | 47 + 6 files changed, 1528 insertions(+), 0 deletions(-) create mode 100644 Documentation/devicetree/bindings/dma/xilinx/xilinx_vdma.txt create mode 100644 drivers/dma/xilinx/Makefile create mode 100644 drivers/dma/xilinx/xilinx_vdma.c create mode 100644 include/linux/amba/xilinx_dma.h -- 1.7.4 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
