ACPI table HMAT has been introduced, QEMU now builds HMAT tables for
Heterogeneous Memory with boot option '-numa node'.
Add test cases on PC and Q35 machines with 2 numa nodes.
Because HMAT is generated when system enable numa, the
following tables need to be added for this test:

Commit 65f14ab98da1 ("usb-host: skip reset for untouched devices")
filters out multiple usb device resets in a row. While this improves
the situation for usb some devices it doesn't work for others :-(
So go add a config option to make the behavior configurable.

This patch set tries enable compress during postcopy.
postcopy requires to place a whole host page, while migration thread migrate
memory in target page size. This makes postcopy need to collect all target
pages in one host page before placing via userfaultfd.
To enable compress during postcopy,
In postcopy, it requires to place whole host page instead of target
page.
Currently, it relies on the page offset to decide whether this is the
last target page. We also can count the target page number during the
iteration. When the number of target page equals
(host page size / target page size)
For the first target page, all_zero is set to true for this round check.
After target_pages introduced, we could leverage this variable instead
of checking the address offset.

The virtio-net fuzz target feeds inputs to all three virtio-net
virtqueues, and uses forking to avoid leaking state between fuzz runs.

specially the compx 2.4g receiver changed from hostaddr 7 to 8 and when
this happens qemu 4 seems to work not as good as qemu 3.

Hi,
I'm working on a project that wants to replace houdini (ARM-to-x86
translation layer for Android from Intel) with a free open-source
implementation. I'm trying to leverage qemu user-mode to achieve that, but
it requires code changes to allow

Most qos-related objects were specified in the qos-test-obj-y variable.
qos-test-obj-y also included qos-test.o which defines a main().
This made it difficult to repurpose qos-test-obj-y to link anything

This now allows changing the logfile while logging is active,
and also solves the issue of a seg fault while changing the logfile.
Any read access to the qemu_logfile handle will use
the rcu_read_lock()/unlock() around the use of the handle.
To fetch the handle we will use atomic_rcu_read().
We al
qemu_log_lock() now returns a handle and qemu_log_unlock() receives a
handle to unlock. This allows for changing the handle during logging
and ensures the lock() and unlock() are for the same file.

One test ensures that the logfile handle is still valid even if
the logfile is changed during logging.
The other test validates that the logfile handle remains valid under
the logfile lock even if the logfile is closed.

This patch adds thread safety to the qemu_logfile handle. This now
allows changing the logfile while logging is active, and also solves
the issue of a seg fault while changing the logfile.
This patch adds use of RCU for handling the swap out of the
old qemu_logfile file descriptor.
Robert Fole
This is being added in preparation for using RCU with the logfile handle.
Also added qemu_logfile_init() for initializing the logfile mutex.
