Dma request synchronization
WebSynchronization refers to co-ordination of pipelined operations performed on buffers. Most GPU clients will schedule an asynchronous operation to render to the buffer, then immediately send the buffer to the compositor to be attached to a surface. WebTo request a channel dma_request_chan () API is used. Interface: struct dma_chan *dma_request_chan(struct device *dev, const char *name); Which will find and return the name DMA channel associated with the ‘dev’ device. The association is done via DT, ACPI or board file based dma_slave_map matching table.
