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).
Incidentals:
* Add a placeholder for RESOURCE_SYNC

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

This CL expands the existing boot.rs test to not just boot a kernel
but also provide a debian-based rootfs and a special init binary
that is used to communicate between test code and the guest VM.
The delegate binary listens for commands on /dev/ttyS1 and returns
the stdout of the executed command.
This allows the test code to setup pipes for the serial device to
issue commands in the client and receive the command output, which
provides a good foundation for tests of basic functionality without
the need to pass test binary code into the guest.
The integration tests will pull a prebuilt kernel and rootfs image
from cloud storage unless local files are specified via ENV variables.
The integration_tests/guest_under_test directory contains the files
needed to build and upload those prebuilts.

rutabaga_gfx is a cross platform, Rust-based, Wayland and
Vulkan-centric Virtual Graphics Interface (VGI).
Apologies for the mega-change, but it was hard to do this piece
by piece.
The rationale for this change is:
1) Android graphics virtualization experts have been proposing
for a VGI for many months (years?). Their goal is to boot
Android anywhere, everywhere.
2) For the {wayland, cross-domain} context type prototype,
it's desirable to create a {wayland, camera} connection at the
appropriate time. Details can be found in the code, though the
RutabagaChannels have yet to be hooked up.
There's a high chance neither effort will work. As such,
rutabaga is just a prototype.
However, even (1) and (2) don't end up working, this
refactor/cleanup by itself makes a ton of sense.
Here's a summary of revelant changes:
* Removed auto-generated {p_defines, p_format, virgl_protocol}.
These files were added for tests when bringing up crosvm-gpu,
and AFAICT these tests are not run. There's actually now a
commit queue for virglrenderer changes and container boot tests
that provides excellent coverage.
* Removed command_buffer.rs. Used only for the previously
mentioned tests. It's quite nice, but couldn't determine the right
place to put it. Maybe data_model? But removed it in the interim.
* Removed {write_from_guest_memory, read_to_volatile}. The same
basic functionality has been moved into {transfer_write,
transfer_read} in Rutabaga.
* Removed VirtioResource, Virtio3DResource, Virtio2DResource,
and VirtioGfxStreamResource in favor of VirtioGpuResource and
RutabagaResource. This leads to less duplication and clearer
separation between external library functions and VMM functions.
* Moved display and hypervisor memory management functions to
virtio_gpu.rs. This is because external components do not interface
with this functionality, and there was a lot of duplication (for example
map/unmap blob).
* Added context management between gfxstream and virglrenderer.
* Added separate gfxstream and virglrenderer flags.
* Clearer naming.
* Added simple implementations for context init and multiple timelines.
These changes have no effect since all Google kernels don't pass the
revelant flags, but are useful for theoretical {wayland, cross-domain}
prototype.
* Unify RESOURCE_CREATE_3D and RESOURCE_CREATE_2D handling.
* Better error handling.

Adds a new backend type, gfxstream, that calls out to a C library
implementing the actual rendering.
The purpose is to allow the Cuttlefish and Android Studio Emulator teams
to use crosvm with the current API-forwarding style of rendering
employed in the Android Studio Emulator.
Also, introduces a new key to the --gpu command line interface,
backend=, which selects from different backends. Note that the previous
behavior is now deprecated and will be removed after some time
(when all clients switch over to backend=).
The gfxstream backend itself implements a subset of 3d-related resource
and context creation/transfer/execbuffer commands. Their meaning is
specific to the way in which they are interpreted in the backend
library.
To interface with display, gfx stream backend takes a callback that is
run on guest vsync. The callback is responsible for repainting the
display's contents. gfx stream provides a callback, get_pixels, that can
be used asynchronously. The asyncness is not taken advantage of
currently but will be useful for cases where the client attached to the
VMM might want to update at a different rate than guest vsync.
The guts of the stream backend library is currently defined here:
https://android.googlesource.com/platform/external/qemu/+/refs/heads/emu-master-dev/android-qemu2-glue/emulation/virtio-goldfish-pipe.cpp
The linking of the library is controlled via the feature "gfxstream".
If the feature is turned off, we use a default do-nothing stub impl.
Next steps:
- integrate virtio-gpu-next so as to have host coherent memory for
vulkan
- Figure out low latency command submit/response with SUBMIT_CMD_3DV2

Drop the dependency on libusb and reimplement the host USB backend using
usb_sys to wrap the Linux usbdevfs ioctls.
This allows sandboxing to work without any dependency on libusb patches,
and it gives us the flexibility to modify and update the USB backend
without depending on an external third-party library.

This adds a new disk file type next to raw files and qcow images that
represent an indirection to further raw disk files. The disk file
itself is a proto file with references to file paths for other disks to
open and their virtual offsets and lengths.
The intention is to make it easy to assemble a single virtual hard disk
out of several distinct partition files. In the particular case of
Cuttlefish running Android in a VM, this is relevant as the Android
build system distributes partitions as separate raw files. While the
simple solution is to pass each partition as a separate raw disk, some
functionality (like the bootloader) assumes there is a partition table
with multiple distinct partitions on a single disk.
Implementing composite disk support in the VMM bridges this gap through
supporting the general-purpose case of a disk built out of multiple
component files.
If desired, this can be extended to support qcow files to support
unusual configurations like a mixed qcow/raw disk.
Enabled with the "composite-disk" feature.

This change has 3 parts:
- Modify the Cargo.toml to point at the bin and the lib source.
- Move modules and Config struct into the lib source
- Fix the argument/plugins module's doc comments which had never been
tested.
The motivation for this change is to make testing crosvm's major
functionality (booting guest kernels, emulating hardware, etc) easier to
do from a cargo test. Being able to launce a crosvm config via the API
instead of the binary's command line will be possible with this change.
A side benefit is that this also enables doc tests in the lib side of
crosvm. The doc tests in binaries are not run due to a limitation in how
they get tested by cargo.

This CL fixes four cases of what I believe are undefined behavior:
- In vhost where the original code allocates a Vec<u8> with 1-byte
alignment and casts the Vec's data pointer to a &mut vhost_memory
which is required to be 8-byte aligned. Underaligned references of
type &T or &mut T are always undefined behavior in Rust.
- Same pattern in x86_64.
- Same pattern in plugin::vcpu.
- Code in crosvm_plugin that dereferences a potentially underaligned
pointer. This is always undefined behavior in Rust.

This matches the version already used by crostini_client.
The newer protobuf version depends on the tempfile crate rather than
tempdir, the latter being now deprecated. So I replaced our immitation
tempdir crate with one that matches the API of tempfile instead. As a
reminder, we use this crate as a patch to avoid pulling in all of the
rand crate and its many dependencies.
