Without memory barrier, the change of used ring index could not
immediately detected by FE, this would bring some problems.
For virtio-blk FE driver, when it receives an interrupt, and confirms the
used ring index has changed, it will first set ring flags with
VRING_AVAIL_F_NO_INTERRUPT, then get buffer from virtqueue, after
process this request, it will mask VRING_AVAIL_F_NO_INTERRUPT, and get
used ring index again before return. If used ring changes, it will
process it. At the same time, BE will read this flags before each notify,
if VRING_AVAIL_F_NO_INTERRUPT was set, BE will not inject interrupt.
Without memory barrier, before FE mask VRING_AVAIL_F_NO_INTERRUPT, BE
has finished notify without interrupt, then FE mask
VRING_AVAIL_F_NO_INTERRUPT, and get used ring index but failed (index
has changed from BE side). FE will return from interrupt handler
function, and wait for next interrupt which was not injected by BE. Thus,
this will cause kernel hung.

To reset USB DRD role is one workaround for adb lost issue with xDCI
passthrough which reproduced in S3 stress test.
This workaround will involve the system global reset if xDCI working in
SuperSpeed mode. This is maybe caused by PMC firmware can't graceful
power gate the xDCI during S3 suspend. The current USB DRD driver will
set STATIC switch bits which will cause ungraceful DRD switch, it may
make the xDCI enter a unknown state, then involved this global reset
issue.
BTW, base on latest code base, the adb lost issue can't reproduce even

To support discard for virtio-blk, the backend file should also located
in a filesystem which support discard. So, mount /data partition with '
-o discard'.
Then, add 'discard' to virtio-blk to enable this feature.
1. Erase operations on UOS will trigger the discard on SOS instead of
writing zero, which will save erase time.
2. Discard in storage firmware will move the mapped host address range to
the unmapped host address range. So, when delete a file in UOS, discard
will trigger the space collection on storage, so that in the next write
operation, it need not to do erase first.

Support DISCARD command is meaningful when eMMC usage is high or
there are lots of remove operations. For example, when Guest
Android is running, there will be lots of files being created and
removed. However, virtio-blk BE does not support DISCARD command,
data remove operation in UOS will not trigger erase in eMMC. After
period of time, the eMMC will be consumed out, and erase must be
done by eMMC firmware before writing any new data. This causes the
eMMC performance decrease in the whole system (SOS and UOS).
To solve the problem, DISCARD should be supported in virtio-blk BE.
