the first cacheline if the buffer start address is not on a cacheline boundary. Normally a buffer which is not cacheline-aligned is bounced, but a special rule applies for mbufs, which are always misaligned due to the header. We know the cpu will not write to the header while dma is in progress (so we've been told anyway), but it may have written to the header shortly before starting a read, so we need to flush that write out to memory before invalidating the whole buffer. In collaboration with Mical Meloun and Svata Kraus. |
