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

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.

Enable the ZERO_MESSAGE_{OPEN,OPENDIR} features when the cache policy is
"always". This feature allows the kernel to skip the open message after
a successful lookup, reducing the amount of work that the server does.
This is implemented by changing the file descriptors stored in the
InodeData from O_PATH fds to O_RDONLY fds for files and directories.
Other types of directory entries (symlinks, special files, etc) still
use O_PATH fds.
If the kernel sends a write request for an fd opened in read-only mode
or a read request for an fd opened in write-only mode (can happen when
creating a new file), then we open a new fd in read-write mode before
performing the read/write. This only needs to happen the first time we
get a request that doesn't match the open flags.
This change should improve performance of opening and reading many small
files. It improves the blogbench read score by ~40% but reduces the
write score by ~25%. It also reduces the work done by the virtio-fs
server when loading roblox. The first load time is reduced by
~17% (3.04 seconds -> 2.52 seconds) and non-initial load times are

The cross-domain context is specialized for cross domain
allocation/resource sharing. It takes direct inspiration from
the pioneering virtio_wl device and tries to incorporate
similiar functionality into virtio_gpu.
The goal here is just to introduce the building blocks so we
can continue experimenting. In particular, this change:
* hooked up the RutabagaChannels. This is typically a socket to
Wayland or Mojo for the camera use case.
* added CROSS_DOMAIN_CMD_INIT and CROSS_DOMAIN_CMD_GET_IMAGE_REQS
to the cross-domain protocol. Further commands (such as
CROSS_DOMAIN_SEND) will be needed, but that requires more
Sommelier refactorings.
* added a path to RutabagaGralloc to allocate via minigbm or shared
memory.
* Recieves responses via a shared ring buffer of type BLOB_MEM_GUEST.
The synchronization protocol looks positively primitive compared to
the revolutionary Address Space Graphics (ASG) algorithm [1], but
it may be sufficient for the Wayland use case.

rutabaga_gralloc is a cross-platform, Rust-based buffer
manager.
The rationale for this change is:
1) For the {cross-domain, wayland} context type, we need to
have a good story for the crucial "wl-dmabuf" feature. As
minigbm has been thoroughly tested on ChromeOS and currently
powers the "wl-dmabuf" feature, it only makes sense for us to
have a path to minigbm for the cross-domain prototype. This
will be used by Sommelier.
2) While minigbm allocation works well on Chromebooks, it is
not sufficient for cross-platform purposes. For their Virtual
Graphics Interface (VGI) initiative, Android graphics
virtualization experts have expressed their desire for a Vulkan
based allocator. This will to go alongside cros_gralloc in
minigbm, which is considered by many to be the ""world's
premiere gralloc implementation".
3) Android graphics virtualization experts have expressed their
desire for vkMapMemory(..) to be used when crosvm is in
multi-process mode. Currently, only dma-buf mmap() is supported
for zero-copy blobs in multi-process mode. dma-buf mmap() is not
guaranteed to work on Nvidia (a "must have" for Cuttlefish) or
any other driver for that matter (we *make* it work for ChromeOS).
Possibly only solution: vkMapMemory ;-)
With these goals in mind, here's a summary of the revelant changes:
* Renamed the {gpu_allocator.rs, GpuMemoryAllocator trait} to be
{gralloc.rs, Gralloc trait}.
* Moved all GPU allocation out of the resources crate and into
the rutabaga_gfx crate. This will allow the resources crate to
be focused on managing resources for virtual machines.
* Moved the gpu_buffer crate into the gralloc module in the
rutabaga_gfx crate. The same functionality is now under
"minigbm.rs", "minigbm_bindings.rs" and "rendernode.rs"
* Added an optional dependency on vulkano.rs. vulkano.rs is a safe
Rust wrapper around the Vulkan api [a]. It's emphasis on type
safety makes a good fit for crosvm, though there are other high
quality crates out there (gfx-rs, ash.rs). Though development
has slowed down, it should satisfy goals (2) and (3) quite easily.
* Added a system_gralloc implementation based on memfd. This can be
used when minigbm or Vulkano features are not used, to replicate the
highly useful "wl-shm" feature in Sommelier. Astute observers will
note this can also enable seamless Wayland windowing without GPU
features for Android too. Some minor changes to the base crate were
needed.
* Cut down on the amount of DrmFormats to the subset needed by
Sommelier and cros_gralloc.
* Moved checked arithmetic into it's own file.
* Internally renamed to "wl-dmabuf" feature to be the "minigbm"
feature. This is because "wl-dmabuf" has a dependency on minigbm.
* Small rutabaga_gfx cleanups

The arcvm guest has been observed to fail early in boot with a low
probability; the root cause seems to be a missing interrupt from the
virtio-block device causing the guest to wait forever for a notification
that does not happen.
In testing, it seems that ignoring the VIRTQ_AVAIL_F_NO_INTERRUPT flag
set by the guest avoids the issue; possibly there is a race in the
publishing of used descriptors versus the checking of this flag, but I
was not able to find a definitive solution.
Ignoring the flag means that we may occasionally trigger an interrupt
when the guest has indicated that one is not necessary; this is, at
worst, a slight performance degradation, not a correctness issue, since
the guest kernel will ignore spurious interrupts.
