Date: Tue, 3 May 2022 20:48:26 +0200 [thread overview]
Message-ID: <20220503184831.78705-1-p.raghav@samsung.com> (raw)

This iteration is against io_uring-big-sqe brach (linux-block).
On top of a739b2354 ("io_uring: enable CQE32").
fio testing branch:

Changes since v2:
- Rewire uring-cmd infrastructure on top of new big CQE
- Prep patch (refactored) and feedback from Christoph
- Add new opcode and structure in nvme for uring-cmd
- Enable vectored-io
Changes since v1:
https://lore.kernel.org/linux-nvme/20220401110310.611869-1-joshi.k@samsung.com/
- Trim down by removing patches for polling, fixed-buffer and bio-cache
- Add big CQE and move uring-cmd to use that
- Remove indirect (pointer) submission
v1:
https://lore.kernel.org/linux-nvme/20220308152105.309618-1-joshi.k@samsung.com/
