this series adds some optimizations for qemu-img during convert which have been developed recently: - skipping input based on get_block_status - variable I/O buffer size - align write requests to cluster_size - show progress in sectors or percent
v1->v2: - introduce opt_transfer_length in BlockLimits [Paolo] - remove knobs for iobuffer_size and alignment and use them unconditionally [Paolo] - calculate I/O buffer size by BlockLimits information [Paolo] - change the alignment patch to round down to the last and not to the next aligned sector [Paolo] - limit updates in the sector progress output - new patch to increase the default for min_sparse [Paolo] Peter Lieven (9): qemu-img: add support for skipping zeroes in input during convert qemu-img: fix usage instruction for qemu-img convert block/iscsi: set bdi->cluster_size block: add opt_transfer_length to BlockLimits block/iscsi: set bs->bl.opt_transfer_length qemu-img: dynamically adjust iobuffer size during convert qemu-img: round down request length to an aligned sector qemu-img: add option to show progress in sectors qemu-img: increase min_sparse to 128 sectors (64kb) block/iscsi.c | 10 +++ include/block/block_int.h | 3 + qemu-img-cmds.hx | 4 +- qemu-img.c | 159 ++++++++++++++++++++++++++++++--------------- qemu-img.texi | 6 +- 5 files changed, 126 insertions(+), 56 deletions(-) -- 1.7.9.5
