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
reduced by 50% (0.3 seconds -> 0.15 seconds).

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.

There are a lot of changes in this one but these are the high-level
points:
* Both executors now support non-fd futures and it's now possible to
start a poll operation on one thread and then await the result inside
a UringExecutor on another thread. The reverse doesn't work yet but
will once we make UringContext sync.
* A few layers of indirection have been removed so hopefully both the
implementation and the interface are simpler.
* The thread local magic is gone in favor of directly calling methods on
an executor. Executor handles can be cheaply cloned to make this
easier.
* Heap allocations are limited to the spawn and spawn_local methods so
it's possible to completely avoid heap allocations if callers only use
the run_until method.
* The IoSource, Executor, FutureList traits are gone.

Support virtio-fs's DAX (direct memory access) operation which allows the guest
to directly access file pages.
Specifically, FUSE_SETUP_MAPPING and FUSE_REMOVE_MAPPING operations are
supported.
This option can be used by specifing `dax` option when mount a file system in
the guest.
The DAX optoin improved file I/O performance in most cases.
In Fio tests, both of read and write score were improved by 1.3-14x depending on
test cases.
In Blogbench tests, which create many small files, DAX improved the write score
by 1.5x while the read score was reduced to ~25% (20391 -> 4593).
Here is an excerpt of results:
Fio
* seq_read: 10.2x (143528 -> 1464911)
* seq_write: 3.3x (61253 -> 896791)
* rand_read: 11.6x (138753 -> 1612739)
* rand_write: 14.6x (61253 -> 896791)
* surfing_read: 1.3x (98473 -> 127907)
* surfing_write: 1.3x (83309 -> 108089)
Blogbench
* read: 0.23x (20391 -> 4593)
* write: 1.50x (248 -> 373)

As part of moving from RawFd to RawDescriptor and related types
(https://crrev.com/c/2462330), the USB attach code was modified to
accept a MaybeOwnedDescriptor instead of a MaybeOwnedFd. Since
MaybeOwnedDescriptor::Owned contains a SafeDescriptor instead of a File,
and the usb_util Device::new() constructor requires a File, a conversion
is required. However, the patch mentioned above used as_raw_descriptor
and File::from_raw_descriptor to do this conversion, but this leaves
both the SafeDescriptor and the newly-created File assuming ownership of
the USB fd. When the SafeDescriptor went out of scope, the fd would be
closed, causing the fd in the File to be invalid (meaning the USB device
does not function at all).
This would show up in the crosvm logs like this:
[devices/src/usb/host_backend/utils.rs:61] fail to submit transfer IoctlFailed(2151175434, Error(25))
[devices/src/usb/xhci/xhci_transfer.rs:399] backend is already disconnected
To fix this, use into_raw_descriptor rather than as_raw_descriptor to
transfer ownership out of the SafeDescriptor without closing the fd.

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.

This CL
- simplifies ac97_bus_master audio thread spawn logic
- makes data ownership more clear for future maintenance
- saves several redundant lock calls
High level design:
ac97_bus_master <=> one AudioThreadInfo for each Ac97Function
<=> start / stop an AudioWorker
Changes in this CL:
- Add AudioWorker which contains the data, logic inside spawn::thread()
and some controls which own by AudioThreadInfo
- Remove `fn audio_thread`.
- Make AudioThreadInfo an audio thread control interface for each
Ac97Function
- `start` consumes an worker and spawn a running thread
- `stop` stops the thread and destroy the worker
- Add is_running support
- Combine several regs.lock() calls to save mutex lock time.
- Add create_audio_worker to create AudioWorker
