At present, crosvm can support handle RDMSR in userspace by read MSR of
Host directly. This is the RDMSR passthrough in userpace.
This patch adds more MSR handler support, including:
- WRMSR passthrough: write the corresponding MSR of Host directly in
userspace; The control of MSR will work on host;
- RDMSR emulation: crosvm uses a dummy MSR value to let Guest reads on.
This value can be different with real MSR of Host;
- WRMSR emulation: crosvm uses a dummy MSR value to let Guest writes
into. This means the control of MSR won't really work (on Host).

This reverts commit d2d66bc0a4.
Reason for revert: It turns out that adding the first page to the pool

since crosvm will actually use it for MMIO regions. The first page
has special semantics in other code though, and thus we get stray
accesses to this region, with hard-to-predict consequences.

The get_high_mmio_base_size() function duplicates and hard-codes the

the plat_mmio variables can be used instead of duplicating the math.
Also reorder the SystemAllocator::builder() calls so that they are in

Platform device is another type of device which might be assigned

In contrary to PCI, platform device has no config space which
describes device resources and makes it self-contained and
self-discoverable. Therefore, platform device resources are described in
FW and host is the one who enumerates/probes devices by parsing DT/ACPI.
We have ioctl i/f which allows to expose all that info to VMM.

Note, for now all IRQs are abstracted to wired line (SPI in ARM GIC world)

The --cpu-cluster option can be used to report a physical grouping of
CPUs in the device tree as a "cpu-map" node:
https://www.kernel.org/doc/Documentation/devicetree/bindings/arm/topology.txt
Each instance of the --cpu-cluster option specifies a new group
consisting of a list of CPUs, and it may be repeated to add multiple
groups.
The --cpu-capacity option can be used to specify the relative
performance of CPUs so that the guest kernel's scheduler can make better
decisions on systems with heterogeneous cores (e.g. big.LITTLE).
--cpu-capacity units are left up to each architecture; for devicetree
systems, capacity is used to fill the cpu capacity-dmips-mhz (Dhrystone
benchmark MIPS per MHz) field in each cpu node:
https://www.kernel.org/doc/Documentation/devicetree/bindings/arm/cpu-capacity.txt
For example, on a trogdor board, there are 6 little cores (0-5) with a
capacity of 452, and 2 big cores (6-7) with a capacity of 1024, which
results in a crosvm command line argument of:
--cpu-capacity 0-452,1=452,2=452,3=452,4=452,5=452,6=1024,7=1024
Currently, these options only have an effect on devicetree platforms and
are ignored elsewhere; they may be expanded in the future to fill in the
equivalent ACPI tables if systems with heterogeneous CPUs are used
there.

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

Allow devices to be added to a Bus without a mutex. If a device
implements BusDeviceSync and is inserted into the Bus via the new
insert_sync function, the Bus will not lock the device before write and
read operations. This feature will allow IrqChip implementations to use
the mmio bus for APIC mmio, and allow each vcpu to write to their
respective APICs simultaneously.
This also changes the BusDevice trait so read and write functions take a
new BusAccessInfo struct. The BusAccessInfo conveys the full address of
the read/write operation, the offset of the address relative to the
device start address, and an id that in practice will hold the vcpu id
for the vcpu thread perforing the read/write.
As a result, inserts into the Bus are no longer distinguished between
full_addr and non full_addr inserts. Instead, each device's BusDevice
implementation must decide whether they use the absolute read/write
address or the relative read/write offset.

This allows code to create references to traits such as `&dyn Vcpu` for
`&dyn IrqChip`. This also allows keeping such traits inside of opaque
`Box` like wrappers.
To achieve this, trait methods referencing `Self` have an additonal
`where` clause that restricts them to sized types. Associated types are
removed and replaced with their trait equivalents (as parameters) or an
opaque Box (as return values).
To work around certain cases where a concrete type is needed, such as
for KVM based `IrqChip` impls, the `downcast_rs` trait is used to allow
`dynamic_cast` style casting.
The binary size impact of this change is small. For comparison, here is

New option, --size-only, speeds up using build_test for getting release
binary size by skipping everything else. The lto flag is also added for
release builds to get a more realistic comparison.
The list of crates to test is built up automatically instead of
hard coded. To modify what gets included, empty .build_test_* files are
checked for existance. This is better than hard coding the list of
packages because it was frequently out of date.
For certain crate tests, a dynamic library that only exists in a sysroot
is required. This change includes a fix that adds the sysroot's lib
directory to the LD_LIBRARY_PATH env variable, similar to how
