e01ee7c6 - dmaengine: Move AMD PTDMA driver to amd directory

Fri, 25 Oct 2024 09:59:26 +0000

dmaengine: Move AMD PTDMA driver to amd directoryPTDMA driver is the AMD DMA driver, and newer AMD platforms support newerDMA engines. Hence, move the current drivers to the AMD directory. Thiswould also mean that future driver submissions to the AMD DMA driver willalso land in the AMD-specific directory.Reviewed-by: Raju Rangoju Signed-off-by: Basavaraj Natikar Link: https://lore.kernel.org/r/20241025095931.726018-2-Basavaraj.Natikar@amd.comSigned-off-by: Vinod Koul List of files: /linux-6.15/drivers/dma/Makefile

73d5fc92 - dmaengine: amd: qdma: Add AMD QDMA driver

Mon, 19 Aug 2024 21:19:48 +0000

dmaengine: amd: qdma: Add AMD QDMA driverAdds driver to enable PCIe board which uses AMD QDMA (the Queue-basedDirect Memory Access) subsystem. For example, Xilinx Alveo V70 AIAccelerator devices. https://www.xilinx.com/applications/data-center/v70.htmlThe QDMA subsystem is used in conjunction with the PCI Express IP blockto provide high performance data transfer between host memory and thecard's DMA subsystem. +-------+ +-------+ +-----------+ PCIe | | | | | | Tx/Rx | | | | AXI | | <=======> | PCIE | <===> | QDMA | <====>| User Logic| | | | | | | +-------+ +-------+ +-----------+The primary mechanism to transfer data using the QDMA is for the QDMAengine to operate on instructions (descriptors) provided by the hostoperating system. Using the descriptors, the QDMA can move data in boththe Host to Card (H2C) direction, or the Card to Host (C2H) direction.The QDMA provides a per-queue basis option whether DMA traffic goesto an AXI4 memory map (MM) interface or to an AXI4-Stream interface.The hardware detail is provided by https://docs.xilinx.com/r/en-US/pg302-qdmaImplements dmaengine APIs to support MM DMA transfers.- probe the available DMA channels- use dma_slave_map for channel lookup- use virtual channel to manage dmaengine tx descriptors- implement device_prep_slave_sg callback to handle host scatter gather listSigned-off-by: Nishad Saraf Signed-off-by: Lizhi Hou Link: https://lore.kernel.org/r/20240819211948.688786-2-lizhi.hou@amd.comSigned-off-by: Vinod Koul List of files: /linux-6.15/drivers/dma/Makefile
