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
