Those are always naturally aligned, so cannot cross a page boundary,
thus instead of generating two 8-byte loads with translation on each
(and double swap for LE on LE), we use a helper that will do a single
translation and memcpy the result over (or do appropriate swapping
if needed).

This adds the skip option which allows qemu-img dd to skip a number of blocks
before copying the input.
A test case was added to test the skip option.

The virtio crypto device is a virtual crypto device (ie. hardware
crypto accelerator card). The virtio crypto device can provide
five crypto services: CIPHER, MAC, HASH, AEAD, KDF, ASYM, PRIMITIVE.
In this patch, CIPHER, MAC, HASH, AEAD services are introduced.

Hi all!
There are some fixes, related to previously posted test
[PATCH] backup: block-job error BUG
I'm not sure that proposed solution is a true way to fix the problem,
but it just works for me.
Vladimir Sementsov-Ogievskiy (3):
blockjob: fix dead pointer in txn list
backup: fix transac
Job may be freed in block_job_unref and in this case this would break
transaction QLIST.
Fix this by removing job from this list before unref.

Prevent a situation, when some jobs from transaction are already
finished and user tries to cancel a job from this transaction.

When there are several backups in one transaction, successed block job
must wait for possible cancelling by other block job (if it fails).

Public bug reported:
I have a VM running rawhide (Fedora development) and I can't poweroff
the machine when I enable virtio-vga. Reboot works correctly. Using QXL
works also. The machine arrive to print the "Powering off" message (from
Linux kernel) but then hangs.
The command line is
/usr/bin/q
Hi,
I have recently started working on QEMU and it seems a daunting task
to say the least, hence I wanted some head-start. I have browsed the
source but I still need to bring closer some dots so I can start
working on some experimental changes. I will have to ask further
questions based on my new
