Hi Kevin, Hanna,
Patch 1 -> patch 5 of this series are already reviewed by Alberto(these
affects throttle framework only), the patch 6 affects qemu block layer,
would you please review this(in the further step, merge this series if
this is acceptable)?

This commit makes the UFS device support query

The next patch would be support for UFS logical

Since v5:
- Fix to print an error message instead of a segmentation fault
when no drive property is specified for a ufs-lu device
Since v4:
Addressed review comment from Stefan Hajnoczi. The fixes are as
follows.
- Keep u->reg fields in host endian (Removed little-endian helper

Universal Flash Storage (UFS) is a high-performance mass storage device
with a serial interface. It is primarily used as a high-performance
data storage device for embedded applications.
This commit contains code for UFS device to be recognized
as a UFS PCI device.
Patches to handle UFS logical
This commit adds support for ufs logical unit.
The LU handles processing for the SCSI command,
unit descriptor query request.
This commit enables the UFS device to process
IO requests.

Hi,
I'm ready to merge this but encountered a bug when testing:
$ qemu-system-x86_64 --device ufs --device ufs-lu
Segmentation fault (core dumped)
Please ensure there is an error message like with SCSI disks:
$ qemu-system-x86_64 --device

For image creation code, we have central fallback code for protocols
that do not support creating new images (like NBD or iscsi). So for
them, you can only specify existing paths/exports that are overwritten
to make clean new images. In such a case, if the given path cannot be
opened (assuming a

Create a socketpair for the console output. This should help eliminate
race conditions around console text early in the boot process that might
otherwise have been dropped on the floor before being able to connect to

By using a socketpair for the console, we don't need the sock_dir
argument for the base class anymore, remove it.
The qtest subclass still uses the argument for the qtest socket for now.

Like we did for the QMP socket, use socketpair() for the console socket
so that hopefully there isn't a race condition during early boot where
data might get dropped on the floor.
"lightly tested"; passes local tests and gitlab CI. Doesn't seem to make
anything worse.
