This series adds the support of DISCARD and WRITE_ZEROES commands and extends the virtio-blk-test to test WRITE_ZEROES command when the feature is enabled. v4: - fixed error with mingw compiler in patch 4 gcc and clang want %lu, but mingw wants %llu for BDRV_REQUEST_MAX_SECTORS. Since is less than INT_MAX, I casted it to integer and I used %d in the format string of error_setg. (mingw now is happy) v3: - rebased on master (I removed Based-on tag since the new virtio headers from linux v5.0-rc1 are merged) - added patch 2 to add host_features field (as in virtio-net) [Michael] - fixed patch 3 (previously 2/5) using the new host_features field - fixed patch 4 (previously 3/5) following the Stefan's comments: - fixed name of functions and fields - used vdev and s pointers - removed "wz-may-unmap" property - split "dwz-max-sectors" in two properties v2: - added patch 1 to use virtio_blk_handle_rw_error() with discard operation - added patch 2 to make those new features machine-type dependent (thanks David) - fixed patch 3 (previously patch 1/2) adding more checks, block_acct_start() for WRITE_ZEROES requests, and configurable parameters to initialize the limits (max_sectors, wzeroes_may_unmap). (thanks Stefan) I moved in a new function the code to handle a single segment, in order to simplify the support of multiple segments in the future. - added patch 4 to change the assert on data_size following the discussion with Thomas, Changpeng, Michael, and Stefan (thanks all) - fixed patch 5 (previously patch 2/2) using local dwz_hdr variable instead of dynamic allocation (thanks Thomas) Thanks, Stefano Stefano Garzarella (6): virtio-blk: add acct_failed param to virtio_blk_handle_rw_error() virtio-blk: add host_features field in VirtIOBlock virtio-blk: add "discard" and "write-zeroes" properties virtio-blk: add DISCARD and WRITE_ZEROES features tests/virtio-blk: change assert on data_size in virtio_blk_request() tests/virtio-blk: add test for WRITE_ZEROES command hw/block/virtio-blk.c | 214 +++++++++++++++++++++++++++++++-- hw/core/machine.c | 2 + include/hw/virtio/virtio-blk.h | 5 +- tests/virtio-blk-test.c | 75 +++++++++++- 4 files changed, 282 insertions(+), 14 deletions(-) -- 2.20.1
