* qemu-io: add aio read/write/flush commandsChristoph Hellwig2009-06-241-0/+353
| | | | | | | | | Add commands to exercise asynchronous reads/writes and to flush all outstanding aio commands. Commands to exercise aio cancellations will follow in a separate patch. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

* Fix dump output in qemu-io.Stefan Weil2009-06-241-4/+4
| | | | | | | | | | | | | | The dump output was not nicely formatted for bytes larger than 0x7f, because signed values expanded to sizeof(int) bytes. So for example 0xab did not print as "ab", but as "ffffffab". I also cleaned the function prototype, which avoids new type casts and allows to remove an existing type cast.

* qemu-io: Optionally verify only part of read dataKevin Wolf2009-05-011-10/+41
| | | | | | | | | | | | There are reasonable test cases where a read must span areas that are not uniformly filled with one pattern but contains several parts. This makes -P useless for them currently. Introducing additional options which determine the part of the read data that should be verified with the given pattern allows to check such reads.

* qemu-io: Verify read data by patterns (Kevin Wolf)aliguori2009-04-181-4/+40
| | | | | | | | | | | This patch adds a -P option to read and readv which allows to compare the read data to a given pattern. This can be used to verify data written by write -P.

* qemu-io: Fix handling of bdrv_is_allocated() return value (Kevin Wolf)aliguori2009-04-181-7/+5
| | | | | | | | | | | bdrv_is_allocated() returns a boolean which indicates if the offset is allocated, not 0 on success and everything else is an error.

* a couple of qemu-io fixes (Christoph Hellwig)aliguori2009-04-181-2/+2
| | | | | | | | | | | | | | | Fix two stupid bugs that I forgot to push out: - qiov->size already is in bytes, no need to shift it - actually use the supplied patter in the writev command Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@7178 c046a42c-6fe2-441c-8c8c-71466251a162
