* ahci-test: test atapi read_cd with bcl, nb_sectors = 0John Snow2016-11-141-7/+29
| | | | | | | | | | | | | | | | | | | | | | | | Commit 9ef2e93f introduced the concept of tagging ATAPI commands as NONDATA, but this introduced a regression for certain commands better described as CONDDATA. read_cd is such a command that both requires a non-zero BCL if a transfer size is set, but is perfectly content to accept a zero BCL if the transfer size is 0. This test adds a regression test for the case where BCL and nb_sectors are both 0. Flesh out the CDROM tests by: (1) Allowing the test to specify a BCL (2) Allowing the buffer comparison test to compare a 0-size buffer (3) Fix the BCL specification in libqos (It is LE, not BE) (4) Add a nice human-readable message for future SCSI command additions Signed-off-by: John Snow <jsnow@redhat.com> Reviewed-by: Kevin Wolf <kwolf@redhat.com> Message-id: 1477970211-25754-4-git-send-email-jsnow@redhat.com [Line length edit --js] Signed-off-by: John Snow <jsnow@redhat.com>

* tests: Don't assume structure of PCI IO base in ahci-testDavid Gibson2016-10-281-6/+7
| | | | | | | | | | | | | | | | | | | | | In a couple of places ahci-test makes assumptions about how the tokens returned from qpci_iomap() are formatted in ways it probably shouldn't. First in verify_state() it uses a non-NULL token to indicate that the AHCI device has been enabled (part of enabling is to iomap()). This changes it to use an explicit 'enabled' flag instead. Second, it uses the fact that the token contains a PCI address, stored when the BAR is mapped during initialization to check that the BAR has the same value after a migration. This changes it to explicitly read the BAR register before and after the migration and compare. Together, these changes will make the test more robust against changes to the internals of the libqos PCI layer.
