Irqthreshold
It seems that writing the IrqThreshold any time that the DMA is not halted (or paused) is inherently a race condition, since (in software) you can't guarantee which descriptors have already been processed while the DMA is running, it's not possible to "update" the IrqThreshold to trigger the interrupt precisely after your last descriptor. WebLinux generic IRQ handling Introduction The generic interrupt handling layer is designed to provide a complete abstraction of interrupt handling for device drivers. It is able to handle all the different types of interrupt controller hardware. Device drivers use generic API functions to request, enable, disable and free interrupts.

WebApr 28, 2024 · For 64-bit address space, i.e. xlnx,addrwidth = 64. The CDMA spec says that: "TAILDESC_PNTR [_MSB] register causes the AXI CDMA SG Engine. to start fetching descriptors starting from the CURDESC_PNTR register value." It seems that DMA will start the transfer if either TAILDESC_PNTR or TAILDESC_PNTR_MSB is written.
