plugins: Add enforcement of QEMU_PLUGIN_CB flags in register R/W callbacks
This patch adds functionality to enforce the requested QEMU_PLUGIN_CB_
flags level passed when registering a callback function using the
plugins API. Each time a callback is about to be invoked, a thread-local
variable will be updated with the level that callback requested. Then,
called API functions (in particular, the register read and write API)
will call qemu_plugin_get_cb_flags() to check the level is at least the
level they require.

plugins: Add register write API
This patch adds a function to the plugins API to allow plugins to write

so all the register-related functions are grouped together in the file.

emulated outside QEMU, in a separate process. vfio-user reuses the
existing VFIO defines, structs and concepts.
It has been earlier discussed as an RFC in:

System type: operating system of the guest (e.g. "LINUX ").
System name: user configurable name of the guest (e.g. "TESTVM ").
System level: distribution and kernel version, if the system type is Linux

docs: define policy forbidding use of AI code generators
There has been an explosion of interest in so called AI code
generators. Thus far though, this is has not been matched by a broadly
accepted legal interpretation of the licensing implications for code
generator outputs. While the vendors may claim there is no problem and
a free choice of license is possible, they have an inherent conflict
of interest in promoting this interpretation. More broadly there is,
as yet, no broad consensus on the licensing implications of code
generators trained on inputs under a wide variety of licenses
The DCO requires contributors to assert they have the right to
contribute under the designated project license. Given the lack of
consensus on the licensing of AI code generator output, it is not
considered credible to assert compliance with the DCO clause (b) or (c)
where a patch includes such generated code.
This patch thus defines a policy that the QEMU project will currently
not accept contributions where use of AI code generators is either
known, or suspected.
These are early days of AI-assisted software development. The legal
questions will be resolved eventually. The tools will mature, and we
can expect some to become safely usable in free software projects.
The policy we set now must be for today, and be open to revision. It's
best to start strict and safe, then relax.
Meanwhile requests for exceptions can also be considered on a case by
case basis.

docs: define policy limiting the inclusion of generated files
Files contributed to QEMU are generally expected to be provided in the
preferred format for manipulation. IOW, we generally don't expect to
have generated / compiled code included in the tree, rather, we expect
to run the code generator / compiler as part of the build process.
There are some obvious exceptions to this seen in our existing tree, the
biggest one being the inclusion of many binary firmware ROMs. A more
niche example is the inclusion of a generated eBPF program. Or the CI
dockerfiles which are mostly auto-generated. In these cases, however,
the preferred format source code is still required to be included,
alongside the generated output.
Tools which perform user defined algorithmic transformations on code are
not considered to be "code generators". ie, we permit use of coccinelle,
spell checkers, and sed/awk/etc to manipulate code. Such use of automated
manipulation should still be declared in the commit message.
One off generators which create a boilerplate file which the author then
fills in, are acceptable if their output has clear copyright and license
status. This could be where a contributor writes a throwaway python
script to automate creation of some mundane piece of code for example.

physmem: Support coordinated discarding of RAM with guest_memfd
A new field, attributes, was introduced in RAMBlock to link to a
RamBlockAttributes object, which centralizes all guest_memfd related
information (such as fd and status bitmap) within a RAMBlock.
Create and initialize the RamBlockAttributes object upon ram_block_add().
Meanwhile, register the object in the target RAMBlock's MemoryRegion.
After that, guest_memfd-backed RAMBlock is associated with the
RamDiscardManager interface, and the users can execute RamDiscardManager
specific handling. For example, VFIO will register the
RamDiscardListener and get notifications when the state_change() helper
invokes.
As coordinate discarding of RAM with guest_memfd is now supported, only
block uncoordinated discard.
Chenyi Qiang [Thu, 12 Jun 2025 08:27:45 +0000 (16:27 +0800)]
ram-block-attributes: Introduce RamBlockAttributes to manage RAMBlock with guest_memfd
Commit 852f0048f3 ("RAMBlock: make guest_memfd require uncoordinated
discard") highlighted that subsystems like VFIO may disable RAM block
discard. However, guest_memfd relies on discard operations for page
conversion between private and shared memory, potentially leading to
the stale IOMMU mapping issue when assigning hardware devices to
confidential VMs via shared memory. To address this and allow shared
device assignement, it is crucial to ensure the VFIO system refreshes
its IOMMU mappings.
RamDiscardManager is an existing interface (used by virtio-mem) to
adjust VFIO mappings in relation to VM page assignment. Effectively page
conversion is similar to hot-removing a page in one mode and adding it
back in the other. Therefore, similar actions are required for page
conversion events. Introduce the RamDiscardManager to guest_memfd to
facilitate this process.
Since guest_memfd is not an object, it cannot directly implement the
RamDiscardManager interface. Implementing it in HostMemoryBackend is
not appropriate because guest_memfd is per RAMBlock, and some RAMBlocks
have a memory backend while others do not. Notably, virtual BIOS
RAMBlocks using memory_region_init_ram_guest_memfd() do not have a
backend.
To manage RAMBlocks with guest_memfd, define a new object named
RamBlockAttributes to implement the RamDiscardManager interface. This
object can store the guest_memfd information such as the bitmap for
shared memory and the registered listeners for event notifications. A
new state_change() helper function is provided to notify listeners, such
as VFIO, allowing VFIO to do dynamically DMA map and unmap for the shared
memory according to conversion events. Note that in the current context
of RamDiscardManager for guest_memfd, the shared state is analogous to
being populated, while the private state can be considered discarded for
simplicity. In the future, it would be more complicated if considering
more states like private/shared/discarded at the same time.
In current implementation, memory state tracking is performed at the
host page size granularity, as the minimum conversion size can be one
page per request. Additionally, VFIO expected the DMA mapping for a
specific IOVA to be mapped and unmapped with the same granularity.
Confidential VMs may perform partial conversions, such as conversions on
small regions within a larger one. To prevent such invalid cases and
until support for DMA mapping cut operations is available, all
operations are performed with 4K granularity.
In addition, memory conversion failures cause QEMU to quit rather than
resuming the guest or retrying the operation at present. It would be
future work to add more error handling or rollback mechanisms once
conversion failures are allowed. For example, in-place conversion of
guest_memfd could retry the unmap operation during the conversion from
shared to private. For now, keep the complex error handling out of the
picture as it is not required.

ui/vnc: Update display update interval when VM state changes to RUNNING
If a virtual machine is paused for an extended period time, for example,
due to an incoming migration, there are also no changes on the screen.
VNC in such case increases the display update interval by
VNC_REFRESH_INTERVAL_INC (50 ms). The update interval can then grow up
to VNC_REFRESH_INTERVAL_MAX (3000 ms).
When the machine resumes, it can then take up to 3 seconds for the first
display update. Furthermore, the update interval is then halved with
each display update with changes on the screen. If there are moving
elements on the screen, such as a video, this can be perceived as
freezing and stuttering for few seconds before the movement is smooth
again.
This patch resolves this issue, by adding a listener to VM state changes
and changing the update interval when the VM state changes to RUNNING.

and the display is refreshed immediately if the timer is expired.
