libqos/ahci: Swap memread/write with bufread/write
Where it makes sense, use the new faster primitives. For generally small reads/writes such as for the PRDT and FIS packets, stick with the more wasteful but easier to debug memread/memwrite. For ahci-test (before migration tests): With this patch: real 0m3.675s user 0m2.582s sys 0m1.718s Without any qtest protocol improvements: real 0m14.171s user 0m12.072s sys 0m12.527s Signed-off-by: John Snow <jsnow@redhat.com> Message-id: 1430864578-22072-6-git-send-email-jsnow@redhat.com
