List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , To: qemu-devel@nongnu.org Cc: Ian Main This patch adds sync modes on top of the work that Stefan Hajnoczi has done. These patches apply on kevin/block with '[PATCH] block: add drive_backup HMP command' also applied. 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. Ian Main (4): Implement sync modes for drive-backup. Add tests for sync modes 'TOP' and 'NONE' Add backing drive while performing backup. Change default to qcow2 for sync mode none. block/backup.c | 104 ++++++++++++++++++++++++++++++------------ blockdev.c | 27 +++++++---- include/block/block_int.h | 4 +- qapi-schema.json | 4 ++ qmp-commands.hx | 1 + tests/qemu-iotests/055 | 67 +++++++++++++++++++++++++-- tests/qemu-iotests/055.out | 4 +- tests/qemu-iotests/group | 2 +- tests/qemu-iotests/iotests.py | 5 ++ 9 files changed, 171 insertions(+), 47 deletions(-) -- 1.8.1.4
