Remove a few ioports that did nothing, but were specifically wired up to
stubs so they would not generate debug prints.
Port 0xed will only be used by Linux if io_delay=alternate is set on the
cmdline, which was only required for some quirky PC hardware.
Ports 0xf0 ("busy latch reset") and 0xf1 ("coprocessor reset") were only
required by some i386 PC clones without native FPU support.
Dropping this code simplifies the removal of the no_legacy cfg which
will be done by a future change.

a. The size of pcie cfg mmio is limited to 64MB, so the max pci bus number is 64.
This isn't ennough for vfio-pci device, as such device's bus number is same as

b. In manatee, CrOS may be required to have the same pcie cfg mmio base and size

Adds another method for fencing where a rutabaga component may provide
an asynchronous callback for fence completion. When this method is
enabled, fences no longer need to be polled on the main thread.
When async_fence_cb is enabled, optional polling still occurs for
Rutabaga Components that still rely on it for other purposes (e.g.
virglrenderer for GL query checking).
Both the old and new methods of fence handling are supported with this
CL; e.g. timer-based polling and async callback, but timer-based polling
is the only one active. Follow-up CL(s) will switch to using the async
callback for each RutabagaComponent. Support for the old timer-based
polling will be removed after the async callback method stabilizes in
production.
Also, use a BTreeMap rather a HashMap since we only expect a dozen or so
entries at most. In such cases, a BTreeMap is faster.
* v1 (lfrb@collabora.com): remove all polling + add async_cb
* v2 (ryanneph@google.com): re-introduce optional polling to fix
virglrenderer that relies on it for GL query checking.
* v3 (ryanneph@google.com): replace timer-based polling with
eventfd-based poll() signaling for components that want to use it.
* v4 (ryanneph@google.com): add async fence handling beside timer-based
polling to support both for a short time.
This is a pseudo-reland of commit
a999284da2, but modifications have been
made to support both fencing methods simultaneously.

The queue size defines the number of available descriptors, that can be
used for exchanging messages between guest and hypervisor. Each
virtio-video command uses at least 1 descriptor (eg. CMD_QUEUE uses 2).
The amount of descriptors in use depends on the number of sessions and
buffers in input and output video queue.
In the worst case scenario the peak number can reach over 672 for 8
simultaneous streams, with 26 + 16 buffers each just for CMD_QUEUE
commands alone.
If the entire queue is overfilled with CMD_QUEUE for OUTPUT queue only,
the driver has no free descriptors for INPUT queue buffers. This leads
to encoder/decoder starvation, hence no OUTPUT buffer can be produced
and no CMD_QUEUE will finish, which leads to dead locking the device.
This patch increases the queue size with consideration of above details
with some headroom to avoid driver's deadlock.

This makes the VirtioDevice::device_type() function return type more
descriptive, and it lets us implement fmt::Display for the type instead
of a custom type_to_str() function.

This patch split msi emulation from vfio-pci to a seperate file
msi.rs and make it usable for other devices. And we make pcie
bridge use msi instead of msi-x. The reason to use msi is that
msi-x would need extra mmio bar allocation, which does not work
when bridge is hotplugged into the system.
BUG=None
TEST=check msi functionality in both pcie root port and vfio device

ITMT option allows VM to enable ITMT scheduling, but it doesn't ensure
the success of ITMT scheduling in VM.
Whether ITMT enabling can succeed depends on HWP and ACPI CPPC support
on hardware.
This option exposes related HWP and CPPC information to VM and the
intel_pstate driver of VM will decide wheter to enable ITMT scheduling
or not.
BUG=b:225375705
TEST=Set `--itmt` and check /proc/sys/kernel/sched_itmt_enabled
