61ee6744f2 rutabaga_gfx: nuke base dependency
The base crate has some nifty abstractions but also
pulls in things like minijail, audio_streams and
various random items.

This prevents true cross-platform interoperatibility,
which requires the ability to upload to crates.io
with relative ease.

This change removes the base crate.  The replacement
strategy is two fold:

- For things like SafeDescriptor which don't have
  adequate solutions on crates.io, just copy it
  internally.  I think SafeDescriptor in particular --
  since it works on bot Windows/Linux should probably
  be made into a separate crate long-term since it is
  generically valuable.  Similarly for the Event and
  WaitContext APIs.  For now, live with the duplication.

- Otherwise, the nix crate does most of the Linux
  specific items.

The cross-domain context type has a lot of dependencies
on Linux sockets / epoll.  This is refactored to look more
like the Fuchsia solution, which uses std::sync::mspc
channels to connect to an utility Wayland FIDL library.

The rest of Rutabaga mostly relies just on SafeDescriptor
and the ability to clone it.  rutabaga_gralloc allows
provides shared memory used via virtwl.

Another thing to call out is zerocopy is now strongly
versioned to the latest stable release on crates.io

I also got rid of #[cfg(feature = "virgl_renderer_next")]
on the renderer server fd, since it was complicating the
refactoring.  SafeDescriptor works everywhere and adding
the #ifdef should be reserved for the lowest-levels of
platform specific code when possible.

Overall, this makes compiling on Fuchsia hosts much
simpler.

BUG=b:273555494
TEST= - run cross_domain context type, see Wayland apps
      - note there is a previous bug in cross domain
        when resizing windows, it occurs before this CL.
        The reason seems to be raciness and can likely be fixed
        gfxstream-like seqno.
      - run gfxstream + virgl on Linux, verify everything works.

51f9faf3a4 rutabaga: Update Vulkano to 0.31.0
- We now have ::empty() for flags instead of ::none().

- PhysicalDeviceType was changed to vulkan_enum which is not Ord, so we
  have to change BTreeMap to HashMap.

- The abstract holders for MemoryType or QueueFamily are gone, so more
  index tracking is required. Some constructors take indices now.

- Physical devices are proper objects now, and are enumerated via the
  instance. To keep things simple, this CL only replaces with equivalent
  logic, but the next one should replace device indices entirely with
  device UUIDs.

- Device memory errors were condensed into a single DeviceMemoryError
  type. We also need to handle the VulkanError type from
  enumerate_physical_devices.

Both libraries have previously been built as part of

build.rs file of rutabaga_gfx.

This is the last third party dependency that we need to build from
source, and allows us to build/test on the host machine instead of
requiring the builder container.

It also allows us to greatly simplify the builder containers, which
I will do in a follow-up CL as we also need to upgrade them to bullseye.

This is the original CL with one minor exception: we don't bind
mount the camera socket with the GPU device.  That was the prior
behavior, and for some reason it really doesn't work with Mali +
SECCOMP[1].  It's not really important for the Wayland prototype,
so we'll let the camera team figure it out if and when they are
so inclined.

a9c4b3a749 rutabaga_gfx: cross-domain: a new year's miracle in February
The cross-domain context is specialized for cross domain

similiar functionality into virtio_gpu.

The goal here is just to introduce the building blocks so we
can continue experimenting.  In particular, this change:

  CROSS_DOMAIN_SEND) will be needed, but that requires more

293913c01a rutabaga_gfx: rutabaga_gralloc: a shimmering beacon of hope
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

028b8044bc crosvm: clearer naming about GPU features
It's possible to compile the gpu device without virgl_renderer.
In fact, in many instances, this may be required.

This builds the gpu device default, but only with --gpu do I see
/dev/dri/renderN128, so this should be safe.

b1394f719d rutabaga_gfx: an electrifying possibility
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.
