okay so this is a page straight out of the Kernel API Manual, bestie β welcome, come sit with me π«Ά
β¨ NAME β¨
xilinx_cdma_start_transfer β Starts cdma transfer π
β¨ SYNOPSIS β¨
void xilinx_cdma_start_transfer (struct xilinx_dma_chan *chan );
like, that's the whole signature. void return, no cap β she just does it and doesn't report back π
πΈ ARGUMENTS πΈ
chanβ a driver specific channel struct pointer, aka the one piece of info you gotta hand over. It's a pointer tostruct xilinx_dma_chanand it's lowkey the main character of this whole function π
