Currently, virtio-blk does all operations serially, which makes every operation wait for all preceding operations to complete. This commit enables the virtio-blk device to run multiple worker threads simultaneously. This allows the virtio-blk device to handle multiple requests in parallel. For now, this feature is behind a runtime command-line flag to make the feature swithable for experiments. BUG=b:267716786 TEST=`cargo test -p devices` passes. TEST=`tast run $DUT arc.AuthPerf.unmanaged_virtio_blk_vm` passes. TEST=`tast run $DUT arc.AuthPerf.unmanaged_virtio_blk_vm` passes with multiple workers enabled by hard-code change. Confirmed multiple virtio_blk threads worked. TEST=`crosvm run --block ...,multiple-workers=true` runs with multiple virtio_blk threads Change-Id: I089768afed3ea0f126c907d7ae62a1c55be1b829 Reviewed-on: https://chromium-review.googlesource.com/c/crosvm/crosvm/+/4272807 Reviewed-by: Daniel Verkamp <dverkamp@chromium.org> Reviewed-by: Keiichi Watanabe <keiichiw@chromium.org> Commit-Queue: Takaya Saeki <takayas@chromium.org> |
