Subject: [PATCH 0/4] Add Support for GET LBA STATUS 16 command in scsi emulation
Date: Tue, 2 Jun 2020 15:41:57 +0800 [thread overview]
Message-ID: <20200602074201.10879-1-lma@suse.com> (raw)
In this current design, The GET LBA STATUS parameter data only contains
an eight-byte header + one LBA status descriptor.
How to test:
host:~ # qemu-system-x86_64 \
...
-drive file=/vm0/disk0.raw,format=raw,if=none,id=drive0,discard=unmap \
-device scsi-hd,id=scsi0,drive=drive0 \
...
guest:~ # dd if=/dev/zero of=/dev/sda bs=512 seek=1024 count=256
guest:~ # sg_unmap -l 1024 -n 32 /dev/sda
guest:~ # sg_get_lba_status /dev/sda -l 1024
No indication of the completion condition
RTP=0
descriptor LBA: 0x0000000000000400 blocks: 32 deallocated
Lin Ma (4):
block: Add bdrv_co_get_lba_status
block: Add GET LBA STATUS support
