Hi, all This version reworked on REQ_FLUSH and REQ_FUA support as suggested by Christoph and dropped the block core bits since Jens has picked them up. Fio test shows bio-based IO path gives the following performance improvement: 1) Ramdisk device With bio-based IO path, sequential read/write, random read/write IOPS boost : 28%, 24%, 21%, 16% Latency improvement: 32%,

Hi, all Changes in v7: - Using vbr->flags to trace request type - Dropped unnecessary struct virtio_blk *vblk parameter - Reuse struct virtblk_req in bio done function - Added performance data on normal SATA device and the reason why make it optional Fio test shows bio-based IO path gives the following performance improvement: 1) Ramdisk device With bio-based IO path, sequential

Hi, Jens & Rusty This version is rebased against linux-next which resolves the conflict with Paolo Bonzini's 'virtio-blk: allow toggling host cache between writeback and writethrough' patch. Patch 1/3 and 2/3 applies on linus's master as well. Since Rusty will pick up patch 3/3 so the changes to block core (adding blk_bio_map_sg()) will have a user. Jens, could you please

This patchset implements bio-based IO path for virito-blk to improve performance. Fio test shows it gives, 28%, 24%, 21%, 16% IOPS boost and 32%, 17%, 21%, 16% latency improvement for sequential read/write, random read/write respectively.

Note: the virtio-vsock device specification is currently under review but not yet finalized. Please review this code but don't merge until I send an update when the spec is finalized. Thanks! v3: * Remove unnecessary 3-way handshake, just do REQUEST/RESPONSE instead of REQUEST/RESPONSE/ACK * Remove SOCK_DGRAM support and focus on SOCK_STREAM first (also drop v2 Patch 1, it's

Hi folks, This version added REQ_FLUSH and REQ_FUA support as suggested by Christoph and rebased against latest linus's tree. Jens, could you please consider picking up the dependencies 1/4 and 2/4 in your tree. Thanks! This patchset implements bio-based IO path for virito-blk to improve performance. Fio test shows bio-based IO path gives the following performance improvement: 1) Ramdisk
