Subject: [PULL v2 13/16] virtio-blk: add zoned storage emulation for zoned devices
Date: Mon, 15 May 2023 12:05:03 -0400 [thread overview]
Message-ID: <20230515160506.1776883-14-stefanha@redhat.com> (raw)
In-Reply-To: <20230515160506.1776883-1-stefanha@redhat.com>
From: Sam Li <faithilikerun@gmail.com>
This patch extends virtio-blk emulation to handle zoned device commands
by calling the new block layer APIs to perform zoned device I/O on
behalf of the guest. It supports Report Zone, four zone oparations (open,
close, finish, reset), and Append Zone.
The VIRTIO_BLK_F_ZONED feature bit will only be set if the host does
support zoned block devices. Regular block devices(conventional zones)
will not be set.
The guest os can use blktests, fio to test those commands on zoned devices.
Furthermore, using zonefs to test zone append write is also supported.
