WebAs an example, to set the interrupt affinity for the Ethernet driver on a server with four CPU cores, first determine the IRQ number associated with the Ethernet driver: # grep eth0 … WebThis value is used for setting the interrupt threshold. When IOC interrupt events occur, an internal counter counts down from the Interrupt Threshold setting. When the count reaches zero, an interrupt out is generated by the DMA engine. Note: The minimum setting for the threshold is 0x01. A write of 0x00 to this register has no effect.

Attempting to set the IrqThreshold to different values on subsequent calls to xilinx_dma_start_transfer() proves unreliable. - As a result, the only safe thing to do is set IrqThreshold=1 (which issues an interrupt on the completion of every segment/BD, as was done in previous versions of the driver). rawley lodge resortWebJoin your friends at the I Ran the D 5k Run/Walk on Saturday, May 6, 2024.

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.
