List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , To: qemu-devel@nongnu.org Cc: kwolf@redhat.com, famz@redhat.com, rjones@redhat.com, Ian Main , stefanha@redhat.com, pbonzini@redhat.com This patch adds sync modes on top of the work that Stefan Hajnoczi has done. These patches apply on kevin/block. Hopefully all is in order as this is my first QEMU patch. Many thanks to Stephan and Fam Zheng for their help. V2: - No longer poll, instead use qemu_coroutine_yield(). - Use bdrv_co_is_allocated(). - Much better SYNC_MODE_NONE test. V3: - A few style fixes. - Better commit message explaining how TOP and NONE operate. - Verified using checkpatch.pl. V4: - Add patch to use the source as a backing hd during backup. - Add patch to default sync mode none to qcow2. V5: - Fix qcow2 patch. Forgot to git add final version. V6: - Default to requiring 'format' when mode is absolute-paths. - Removed one bad hunk that was misapplying. - Fixed docs, examples and tests to match changes. - Added tests for format bad/missing. - Added bdrv_set_in_use() to target. - Default to qcow2 patch not required. Ian Main (3): Implement sync modes for drive-backup. Add tests for sync modes 'TOP' and 'NONE' Add backing drive while performing backup. block/backup.c | 107 +++++++++++++++++++++++++++++------------ blockdev.c | 36 +++++++++----- include/block/block_int.h | 4 +- qapi-schema.json | 4 +- qmp-commands.hx | 2 + tests/qemu-iotests/055 | 108 +++++++++++++++++++++++++++++++++++++----- tests/qemu-iotests/055.out | 4 +- tests/qemu-iotests/group | 2 +- tests/qemu-iotests/iotests.py | 5 ++ 9 files changed, 211 insertions(+), 61 deletions(-) -- 1.8.1.4
