0e29379bcf vmm: Make gdb break/resuming more resilient
When starting the VM such that it is already on a breakpoint (via
stop_on_boot) when attached to gdb then start the vCPUs in a paused
state rather than starting the vCPUs later (upon resume).

Further, make the resumption/break of the VM more resilient by only
attempting to resume the vCPUs if were are already in a break point and
only attempting to pause/break if we were already running.

Fixes: #4354

45fbf840db hypervisor, vmm: move away from CpuId type
CpuId is an alias type for the flexible array structure type over
CpuIdEntry. The type itself and the type of the element in the array
portion are tied to the underlying hypervisor.

Switch to using CpuIdEntry slice or vector directly. The construction of
CpuId type is left to hypervisors.

This allows us to decouple CpuIdEntry from hypervisors more easily.

a455917db5 vmm: fix missed API or debug events
Previously, we were assuming that every time an eventfd notified us,
there was only a single event waiting for us.  This meant that if,
while one API request was being processed, two more arrived, the
second one would not be processed (until the next one arrived, when it
would be processed instead of that event, and so on).  To fix this,
make sure we're processing the number of API and debug requests we've
been told have arrived, rather than just one.  This is easy to
demonstrate by sending lots of API events and adding some sleeps to
make sure multiple events can arrive while each is being processed.

For other uses of eventfd, like the exit event, this doesn't matter —
even if we've received multiple exit events in quick succession, we
only need to exit once.  So I've only made this change where receiving
an event is non-idempotent, i.e. where it matters that we process the
event the right number of times.

Technically, reset requests are also non-idempotent — there's an
observable difference between a VM resetting once, and a VM resetting
once and then immediately resetting again.  But I've left that alone
for now because two resets in immediate succession doesn't sound like
something anyone would ever want to me.

121729a3b0 vmm: Split signal handling for VM and VMM signals
The VM specific signal (currently only SIGWINCH) should only be handled
when the VM is running.

The generic VMM signals (SIGINT and SIGTERM) need handling at all times.

Split the signal handling into two separate threads which have differing
lifetimes.

Tested by:
1.) Boot full VM and check resize handling (SIGWINCH) works & sending
    SIGTERM leads to cleanup (tested that API socket is removed.)
2.) Start without a VM and send SIGTERM/SIGINT and observe cleanup (API
    socket removed)
3.) Boot full VM, delete VM and observe 2.) holds.
4.) Boot full VM, delete VM, recreate VM and observe 1.) holds.

93237f0106 vmm: Set MADT "Online Capable" flag
The Linux kernel now checks for this before marking CPUs as
hotpluggable:

commit aa06e20f1be628186f0c2dcec09ea0009eb69778
Author: Mario Limonciello <mario.limonciello@amd.com>
Date:   Wed Sep 8 16:41:46 2021 -0500

    x86/ACPI: Don't add CPUs that are not online capable

    A number of systems are showing "hotplug capable" CPUs when they
    are not really hotpluggable.  This is because the MADT has extra
    CPU entries to support different CPUs that may be inserted into
    the socket with different numbers of cores.

    Starting with ACPI 6.3 the spec has an Online Capable bit in the
    MADT used to determine whether or not a CPU is hotplug capable
    when the enabled bit is not set.

65ec6631fb vmm: cpu: Store the vCPU snapshots in ascending order
The snapshots are stored in a BTree which is ordered however as the ids
are strings lexical ordering places "11" ahead of "2". So encode the
vCPU id with zero padding so it is lexically sorted.

This fixes issues with CPU restore on aarch64.

See: #4239

81ba70a497 pci, vmm: Defer mapping VFIO MMIO regions on restore
When restoring a VM, the restore codepath will take care of mapping the
MMIO regions based on the information from the snapshot, rather than
having the mapping being performed during device creation.

When the device is created, information such as which BARs contain the
MSI-X tables are missing, preventing to perform the mapping of the MMIO
regions.

65dc1c83a9 vmm: cpu: Save and restore CPU states during snapshot/restore
Based on recent KVM host patches (merged in Linux 5.16), it's forbidden
to call into KVM_SET_CPUID2 after the first successful KVM_RUN returned.
That means saving CPU states during the pause sequence, and restoring
these states during the resume sequence will not work with the current
design starting with kernel version 5.16.

In order to solve this problem, let's simply move the save/restore logic
to the snapshot/restore sequences rather than the pause/resume ones.

ade3a9c8f6 virtio-devices, vmm: Optimised async virtio device activation
In order to ensure that the virtio device thread is spawned from the vmm
thread we use an asynchronous activation mechanism for the virtio
devices. This change optimises that code so that we do not need to
iterate through all virtio devices on the platform in order to find the
one that requires activation. We solve this by creating a separate short
lived VirtioPciDeviceActivator that holds the required state for the
activation (e.g. the clones of the queues) this can then be stored onto
the device manager ready for asynchronous activation.

5f722d0d3f vmm: Fix loading RAW firmware
Whenever going through the codepath of loading a RAW firmware, we always
add an extra RAM region to the guest memory through the memory manager.
But we must be careful to use the updated guest memory rather than a
previous reference that wasn't containing the new region, as this can
lead to the following error:

VmBoot(FirmwareLoad(InvalidGuestAddress(GuestAddress(4290772992))))

This is fixed by the current patch, getting the latest reference onto
the guest memory from the memory manager right after the new region has
been added.

c47e3b8689 gdb: Do not use VmmOps for memory manipulation
We don't use the VmmOps trait directly for manipulating memory in the
core of the VMM as it's really designed for the MSHV crate to handle
instruction decoding. As I plan to make this trait MSHV specific to
allow reduced locking for MMIO and PIO handling when running on KVM this
use should be removed.

user from creating a disk such as "__serial" which would then cause a

fdeb4f7c46 Revert "vmm, openapi: Token Bucket fields should be uint64"
This reverts commit 87eed369cd.

The reason we're reverting this is that OpenAPI Specification[0] doesn't
know how to deal with unsigned types. :-/

Right now the best to do is keep it as it's, as an int64, and try to fix
OpenAPI, or even switch to swagger, as the latter knows how to properly
deal with those.  However, switching to swagger is far from being an 1:1
transition and will require time to experiment, thus reverting this for
now seems the best approach.

Instead of defining some very generic resources as PioAddressRange or
MmioAddressRange for each PCI BAR, let's move to the new Resource type
PciBar in order to make things clearer. This allows the code for being
more readable, but also removes the need for hard assumptions about the
MMIO and PIO ranges. PioAddressRange and MmioAddressRange types can be
used to describe everything except PCI BARs. BARs are very special as
they can be relocated and have special information we want to carry
along with them.

7fd76eff05 vmm: Don't error if live resizing is not possible
The introduction of a error if live resizing is not possible is a
regression compared to the original behaviour where the new size would
be stored in the config and reflected in the next boot. This behaviour
was also inconsistent with the effect of resizing with no VM booted.

Instead of generating an error allow the code to go ahead and update the
config so that the new size will be available upon the reboot.

2c8045343c vmm,cpu: Deny resizing only if the vcpu amount has changed
188078467d made clear that resize should
only happen when dealing with a "dynamic" CpuManager.  Although this is
very much correct, it causes a regression on Kata Containers (and on any
other consumer of Cloud Hypervisor) in cases where a resize would be
triggered but the vCPUs values wouldn't be changed.

There's no doubt Kata Containers could do better and do not call a
resize in such situations, and that's something that should **also** be
solved there.  However, we should also work this around on Cloud
Hypervisor side as it introduces a regression with the current Kata
Containers code.

6b0df31e5d vmm: Add support for enabling AMX in vm guests
AMX is an x86 extension adding hardware units for matrix
operations (int and float dot products). The goal of the extension is
to provide performance enhancements for these common operations.

On Linux, AMX requires requesting the permission from the kernel prior
to use. Guests wanting to make use of the feature need to have the
request made prior to starting the vm.

This change then adds the first --cpus features option amx that when
passed will enable AMX usage for guests (needs a 5.17+ kernel) or
exits with failure.

The activation is done in the CpuManager of the VMM thread as it
allows migration and snapshot/restore to work fairly painlessly for
AMX enabled workloads.

7a8061818e vmm: Don't expose MemoryManager ACPI functionality unless required
When running non-dynamic or with virtio-mem for hotplug the ACPI
functionality should not be included on the DSDT nor does the
MemoryManager need to be placed on the MMIO bus.

Fixes: #3883

f6dfb42a64 vmm: cpu: Don't place CpuManager on MMIO bus when non-dynamic
This is now consistent with not supplying the _CRS for the device when
CpuManager is not dynamic.

1756b23aea vmm: device_manager: Check IOMMU placed device hotplug
Rather than just printing a message return an error back through the API
if the user attempts to hotplug a device that supports being behind an
IOMMU where that device isn't placed on an IOMMU segment.

Ensure devices that are specified to be on a PCI segment that is behind
the IOMMU are IOMMU enabled if possible or error out for those devices
that do not support it.

6d2224f1ba vmm: device_manager: Create IOMMU mapping for hotplugged virtio devices
Previously it was not possible to enable vIOMMU for a virtio device.
However with the ability to place an entire PCI segment behind the
IOMMU the IOMMU mapping needs to be setup for the virtio device if it is
behind the IOMMU.

This can already be calculated by the summing the tables reported by the
Linux kernel but this is more convenient.
