Subject: [RFC v4 0/9] Add support for zoned device
Date: Tue, 12 Jul 2022 10:13:36 +0800	[thread overview]
Message-ID: <20220712021345.8530-1-faithilikerun@gmail.com> (raw)

This patch series adds support for zoned device to virtio-blk emulation. Zoned
Storage can support sequential writes, which reduces write amplification in SSD,
leading to higher write throughput and increased capacity.

v4:
- add block layer APIs (revision)
- add configurations for zoned block device

Sam Li (9):
  block: add block layer APIs resembling Linux ZonedBlockDevice ioctls.
  qemu-io: add zoned block device operations.
  file-posix: introduce get_sysfs_long_val for a block queue of sysfs
    attribute
  file-posix: introduce get_sysfs_str_val for device zoned model.
  qemu-iotests: test new zone operations.
  raw-format: add zone operations
  config: add check to block layer
  include: add support for zoned block devices
  qapi: add support for zoned host device
