Could someone more knowledgeable than me please reassure me ... Referring to code in linux-2.6.22.1: libata-core.c (kernel.org), in ata_fill_sg():
if sg_dma_address(sg) is 64k-aligned and sg_dma_len(sg) is 64k (0x10000), then in the while loop, the "if ((offset..." test is false, since it tests for *greater than* 64k So then ap->prd[idx].flags_len gets set to (0x10000 & 0xFFFF) = 0 ! So this sg element ends up with a zero length, even though the transfer size should be 64k. Is this correct behaviour, if not, should it be corrected ? Sorry if I'm just being paranoid !
