The current design of having the VDA instance outside of the Decoder was
mandated by the use of lifetimes on libvda Sessions, which have been
removed from libvda. So it is now possible for the Decoder to own its
VDA instance.
This makes sense in itself since there is no reason for the VDA instance
to also be used by someone else, but is also required to add support for
non-libvda decoder backends.

In multi-process mode, we currently rely on dma-buf mmap() to
map GPU buffers into the guest. We usually have to fix the
Mesa driver, and maybe even the kernel to get to work. That's
"kind of" fine for ChromeOS, which owns the entire stack.
For their Virtual Graphics Interface (VGI) initiative, Android
upstream has requested multi-process mode to work in a
cross-platform, generic way. Using Vulkan is the only option
that meets the rigorous, uncompromising, strict, meticulous and
bone-crushing requirements of Android upstream.
This has possible two benefits:
1) We can enable multi-process mode on Nvidia or other
closed-source drivers, which is nice for Cuttlefish.
2) On open-source drivers, dma-buf memory is pinned to the
GTT (amdgpu), even when ideally it can be moved into faster
vram regions. This atleast gives the implementation the
chance to do the smarter and faster option.
We shouldn't run into any SELinux issues since the main crosvm
process is not sandboxed.
Incidentals:
* Changes vulkano_gralloc to consider integrated GPUs and dGPUs.
Metadata query is preferred done on the integrated GPU.
* Update vulkano_gralloc to match top of tree vulkano.

This patch adds support for creating udmabufs via a guest provided
sg-list. Ideally, we'd create the udmabuf from a virtio-gpu guest
dedicated heap, but that needs further investigation.
In terms of the protocol, these following prototype items are added:
BLOB_CREATE_GUEST_HANDLE: "create an udmabuf" or an OS-specific
equivalent. This can be used with the guest dedicated heap or system
memory. Right now, only system memory is used.
We also want to associate the udmabuf with any host side metadata. For
example, SET_SCANOUT_BLOB doesn't passthrough the modifiers since
virtio-gpu KMS + modifiers is annoying. Simple solution: just ask the
host for the modifier. This could also enable different caching types
if the guest blob is mappable (for example, the MSM GPU driver currently
only supports WC mappings. We might also want cached mappings for
camera).

Hello everyone ..! After 2.5 years of "on the side" inquiries,
I have finally completed my investigations [1] of the udmabuf!!
udmabuf is a kernel driver that turns memfd pages into dmabufs.
The original hope was it would reduce texture upload costs for
virgl, which it did for larger textures [2]. But no measurable
improvements where seen with real games. In addition, a more
advanced "gfx-streaming" model has since come into the horizon[3][4],
which is more performant, conformant, secure and simpler than
virgl. As such, building more on virgl does not seem to be best
option, but that's another story for another day.
Where does that leave udmabuf, then?!? The investigation was
able to turn up two possible use cases:
1) Intel integrated + dGPU PCI-passthrough resource sharing
When the dGPU is passthroughed into the guest, the dGPU's memory
is not available to the host. Ideally, for zero-copy, we would
like to get the render target out of the guest somehow and then
send to the display. Many approaches have been proposed, such
as Vivek Kasireddy's Vdmabuf driver [5]. The current thinking
is virtgpu guest blobs can be exported, and then imported into
the dGPU -- Vivek is looking into this approach right now ..!!
Sommelier or virtgpu KMS can then share the guest blob with the
host. It's a quite complex use case and requires changes to guest
Mesa GBM to get (such as metadata query) to get the right modifier.
Indeed, some would even say you need a virtgpu context type optimized
for sharing across domain boundaries. minigbm already supports this
for Android upstream's Virtual Graphics Interface (VGI) initiative.
2) Guest VRAM dedicated heap created udmabufs
This use case, proposed by automative virtualization expert Dmitry
Sepp [6], is primarily for automotive hypervisors (such COQOS).
It's typically not easy for such hypervisors to get zero-copy via
BLOB_MEM_HOST3D, and these hypervisors have had their homebrew
versions of udmabuf for many years. It's important to upstream the
workarounds that are currently done for such hypervisors. To increase
security and isolation, a guest dedicated heap is preferred over guest
system memory. We might even need dedicated queues, who knows.
crosvm seems like the most likely upstream target due to it's world
class blob support and open-source nature. As such, this CL adds basic
udmabuf capabilites so these use cases can be developed further via
crosvm.

Previously we restricted the virtio_input_event/input_event's value
field to u32. In actuality, this field is an i32 in the kernel, and the
negative values are used for relative mice (among other things). This CL
switches the value field to be signed.

To be truly OS-agnostic, we need an OS-agnostic Rust wrapper over
the OS-specific handle type. SafeDescriptor seems to be the best
option, and I hope it on crates.io in the future.
This converts virtio_gpu/rutabaga to use the SafeDescriptor handle
when practical. minigbm still uses File in some places, since it
needs to SeekFrom(..), but minigbm is a Linux only thing anyways.

Some judgement calls were made about unnecessary wrapping. Usually they
would get resolved by removing the wrapping or returning a convenient
error, but the ones that returned results for consistency with other
functions were added to the allow list.
The error handling in the usb code had a lot of unit error types which
is now a clippy lint. This was resolved by either removing the result
entirely or returning a convenient error.
The field_reassign_with_default lint is faulty and was added to the list
of supressions. This affected virtio-wayland code.

For some PCI device, its MMIO bar size may not be page size aligned.
When setting user memory region for such bar with not aligned size, KVM
will report failure back and failed to map that bar. As current crosvm
can continue run with this failure, the performance will be hurt as each
time when guest is accessing this bar, it will trap to hypervisor.
To resolve this, extend the size to be page size aligned when setting
user memory region in KVM and do DMA map. This should be safe to extend
because the mmap actually rounds up the mmap size to be page aligned.
