Hi,
I am implementing a plugin that allocates several resources. I need to
cleanup some of these resources when QEMU finishes executing the guest
application. Where is the best exit point to place my cleanup functions?
I have tried registering a function call "atexit" but it does not seem

This allows forwarding TCP6 and UDP6 connections down to

The following patch implements ipv6 host port forwarding support
for qemu slirp net subsystem.
The slirp itself supports ipv6 communication, but
hostfwd currently does not allow listening on and forwarding
ports for ipv6 addresses.
This should be useful, when host works in v6-capable environment

There are two scenarios here, if we have a regular, directly assigned
physical device (including VFs), vfio's page pinning will populate the
full memory footprint of the guest regardless of the balloon. The
balloon is effectively fully deflated, but the balloon driver in the
guest hasn't released
Alex, I see this issue is closed but I have a question, do you know if
the problem only comes the balloon is resized to return memory to the
host. I ask because we have a situation where we will start a VM with
balloon enabled, and later it maybe possible a devices is assigned via
hot-plug. So I

Yes, I messed up with `-device`, because I initially tried to do it with

This will allow us to add TCG helpers at run-time.
While at it, rename tcg_find_helper to tcg_helper_find for consistency
with the added tcg_helper_foo functions.

The goals are to:
- Have a simple implementation that shares nothing with tracing code.
- Make sure we cannot deadlock, particularly under MTTCG. For this,
we acquire a lock when called from plugin code, and keep
RCU lists of callbacks so that we do not have to hold the lock
when calling

These "hooks" are callbacks from the guest to plugins. This is
useful when we need guest-host communication, for instance to
signal the beginning/end of a certain "region of interest" in
the guest program. Simulators typically would use "magic"
instructions for this, but that is painful to

XXX: store hostaddr from non-i386 TCG backends
XXX: what hostaddr to return for I/O accesses?
XXX: what hostaddr to return for cross-page accesses?
Here the trickiest feature is passing the host address to
memory callbacks that request it. Perhaps it would be more
appropriate to pass a "physical"

Here we implement several features:
- Inlining TCG code for simple operations. Crucially, we do not
export TCG ops to plugins. Instead, we give them a C API to
insert inlined ops. So far we only support adding an immediate
to a u64, e.g. to count events.
- "Direct" callbacks. These are
Add the API first to ease review.

For now only add it for ELF platforms, since we rely on the linker's
--dynamic-list flag to pass a list of symbols to be exported to the
executable. An alternative would be to use -rdynamic, but that would
expose all of QEMU's objects to plugins.
