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.

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/Kconfig

dmaengine: fsl-edma: avoid linking both modulesKbuild does not support having a source file compiled multiple timesand linked into distinct modules, or built-in and modular at thesame time. For fs-edma, there are two common components that arelinked into the fsl-edma.ko for Arm and PowerPC, plus the mcf-edma.komodule on Coldfire. This violates the rule for compile-testing:scripts/Makefile.build:236: drivers/dma/Makefile: fsl-edma-common.o is added to multiple modules: fsl-edma mcf-edmascripts/Makefile.build:236: drivers/dma/Makefile: fsl-edma-trace.o is added to multiple modules: fsl-edma mcf-edmaI tried splitting out the common parts into a separate modules, butthat adds back the complexity that a cleanup patch removed, and itgets harder with the addition of the tracepoints.As a minimal workaround, address it at the Kconfig level, by disallowingthe broken configurations.Link: https://lore.kernel.org/lkml/20240110232255.1099757-1-arnd@kernel.org/Fixes: 66aac8ea0a6c ("dmaengine: fsl-edma: clean up EXPORT_SYMBOL_GPL in fsl-edma-common.c")Signed-off-by: Arnd Bergmann Acked-by: Peng Fan Link: https://lore.kernel.org/r/20240528115440.2965975-1-arnd@kernel.orgSigned-off-by: Vinod Koul List of files: /linux-6.15/drivers/dma/Kconfig
