Subject: [PATCH v9 0/5] Add zoned storage emulation to virtio-blk driver
Date: Fri, 24 Mar 2023 18:13:52 +0800 [thread overview]
Message-ID: <20230324101357.2717-1-faithilikerun@gmail.com> (raw)
This patch adds zoned storage emulation to the virtio-blk driver.
The patch implements the virtio-blk ZBD support standardization that is
recently accepted by virtio-spec. The link to related commit is at
https://github.com/oasis-tcs/virtio-spec/commit/b4e8efa0fa6c8d844328090ad15db65af8d7d981
The Linux zoned device code that implemented by Dmitry Fomichev has been
released at the latest Linux version v6.3-rc1.
Aside: adding zoned=on alike options to virtio-blk device will be
considered in following-up plan.
v9:
- address review comments
* add docs for zoned emulation use case [Matias]
* add the zoned feature bit to qmp monitor [Matias]
* add the version number for newly added configs of accounting [Markus]
v8:
- address Stefan's review comments
* rm aio_context_acquire/release in handle_req
* rename function return type
* rename BLOCK_ACCT_APPEND to BLOCK_ACCT_ZONE_APPEND for clarity
v7:
- update headers to v6.3-rc1
v6:
- address Stefan's review comments
* add accounting for zone append operation
* fix in_iov usage in handle_request, error handling and typos
v5:
- address Stefan's review comments
* restore the way writing zone append result to buffer
* fix error checking case and other errands
v4:
- change the way writing zone append request result to buffer
- change zone state, zone type value of virtio_blk_zone_descriptor
- add trace events for new zone APIs
v3:
- use qemuio_from_buffer to write status bit [Stefan]
- avoid using req->elem directly [Stefan]
- fix error checkings and memory leak [Stefan]
v2:
- change units of emulated zone op coresponding to block layer APIs
- modify error checking cases [Stefan, Damien]
v1:
- add zoned storage emulation
