[PATCH 0/2] support BLKSECDISCARD

Posted by yadong.qi@intel.com 4 years, 2 months ago

From: Yadong Qi <yadong.qi@intel.com>

Support BLKSECDISCARD passthrough for raw host_device backend.

For virtio-blk device:
    Add new virtio feature: VIRTIO_BLK_F_SECDISCARD.
    Add new virtio command: VIRTIO_BLK_T_SECDISCARD.

Usage:
    qemu-system-x86_64 \
    ... \
    -drive file=/dev/mmcblk0p2,if=none,format=raw,discard=on,secdiscard=on,id=sd0 \
    -device virtio-blk-pci,drive=sd0,id=sd0_vblk \
    ...

Yadong Qi (2):
  block:hdev: support BLKSECDISCARD
  virtio-blk: support BLKSECDISCARD
