Hi,
+ if (s->sg_third_party) {
+ /* We've already parsed the guest RAM PRDT.
+ * This is essential for AHCI, where the PRDT is in a different
+ * format than in IDE BMDMA.
+ */
+ memcpy((uint8_t *)&prd, s->sg.sg, sizeof(prd));
+ s->sg.sg++;
+ } else {
+ cpu_physical_memory_read(bm->cur_addr, (uint8_t *)&prd, 8);
+ bm->cur_addr += 8;
+ prd.addr = le32_to_cpu(prd.addr);
+ prd.size = le32_to_cpu(prd.size);
+ }
Does it make sense to handle this via IDEBusOps too? cheers, Gerd
