I have not found wherever in docs how many EDMA requests are submitted per a
single PCI transfer and how to determine and set up properly the PCI EDMA queue
length. I supposed that must be only one request but it seems to be not actually true. In my application I always have a problem with lost PCI transfers unless I set up that queue length to 14. But this is not acceptable for my case. Does anyone know how to do it right, and hence find a way to reduce queue lenth? Thnx. |
