Because it's a sequential scan to get the completion status, so the count may >0 even error was true. e.g.
request 1 successful
request 2 successful
request 3 fail
so the rte_dma_completed(dev_id, vchan, 3, &idx, &error) will return 2 and error was mark with true.
If return 0 and error with true in above situation, this means that the driver must scans all completions first. which
will lead to low performance.
Therefore, the recommended handling method is as follows:
count = rte_dma_completed(dev_id, vchan, COMP_BURST_SZ, &idx, &error);
if (likely(count > 0)) {
// process success completed
}
if (unlikely(error)) {
//
}
