37521ddff7 pci: vfio: Restore BARs in a more straightforward way 
In case a list of resources is provided to allocate_bars(), it directly
means we're restoring some existing BARs. That's why we shouldn't share
the codepath that creates BARs from scratch as we don't need to interact
with the device to retrieve the information.

Whenever resources are provided, we simply iterate over the list of
possible BAR indexes and create the BARs if the resource could be found.

11e9f43305 vmm: Use new Resource type PciBar 
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.

ed87e42e6f vm-device, pci, devices: Remove InterruptSourceGroup::{un}mask 
The calls to these functions are always preceded by a call to
InterruptSourceGroup::update(). By adding a masked boolean to that
function call it possible to remove 50% of the calls to the
KVM_SET_GSI_ROUTING ioctl as the the update will correctly handle the
masked or unmasked case.

This causes the ioctl to disappear from the perf report for a boot of

The same way we mask the writes coming from the guest to the message

The point is to prevent the guest from writing to read-only bits.

16-bit word.

Those are:

* MSI Enable: 0
* Multiple Message Enable: 6-4

b11a8a5ab5 pci: vfio: Mmap region based on capabilities 
Now that vfio-ioctls correctly exposes the list of capabilities related
to each region, Cloud Hypervisor can decide to mmap a region based on
the presence or absence of MSIX_MAPPABLE. Instead of blindly mmap'ing
the region, we check if the MSI-X table or PBA is present on the BAR,
and if that's the case, we look for MSIX_MAPPABLE.
If MSIX_MAPPABLE is present, we can go ahead and mmap the entire region.
If MSIX_MAPPABLE is not present, we simply ignore the mmap'ing of this
region as it wouldn't be supported.

ed5f25446a pci: vfio: Support mapping BAR containing MSI-X 
In order to get proper performance out of hardware that might be passed
through the VM with VFIO, we decide to try mapping any region marked as
mappable, ignoring the failure and moving on to the next region. When
the mapping succeeds, we establish a list of user memory regions so that
we enable only subparts of the global mapping through the hypervisor.
This allows MSI-X table and PBA to keep trapping accesses from the guest
so that the VMM can properly emulate MSI-X.

0eb78ab177 vmm: Extract PCI related state from DeviceManager 
Move the PCI related state from the DeviceManager struct to a PciSegment
struct inside the DeviceManager. This is in preparation for multiple
segment support. Currently this state is just the bus itself, the MMIO
and PIO config devices and hotplug related state.

The main change that this required is using the Arc<Mutex<PciBus>> in
the device addition logic in order to ensure that
the bus could be created earlier.

0faa7afac2 vmm: Add fast path for PCI config IO port 
Looking up devices on the port I/O bus is time consuming during the
boot at there is an O(lg n) tree lookup and the overhead from taking a
lock on the bus contents.

Avoid this by adding a fast path uses the hardcoded port address and
size and directs PCI config requests directly to the device.

Command line:
target/release/cloud-hypervisor --kernel ~/src/linux/vmlinux --cmdline "root=/dev/vda1 console=ttyS0" --serial tty --console off --disk path=~/workloads/focal-server-cloudimg-amd64-custom-20210609-0.raw --api-socket /tmp/api

PIO exit: 17913
PCI fast path: 17871
Percentage on fast path: 99.8%

perf before:

marvin:~/src/cloud-hypervisor (main *)$ perf report -g | grep resolve
     6.20%     6.20%  vcpu0            cloud-hypervisor    [.] vm_device:🚌:Bus::resolve

perf after:

marvin:~/src/cloud-hypervisor (2021-09-17-ioapic-fast-path *)$ perf report -g | grep resolve
     0.08%     0.08%  vcpu0            cloud-hypervisor    [.] vm_device:🚌:Bus::resolve

The compromise required to implement this fast path is bringing the
creation of the PciConfigIo device into the DeviceManager::new() so that
it can be used in the VmmOps struct which is created before
DeviceManager::create_devices() is called.

This needed a bunch of manual updates as well, including vfio-ioctls and
vhost crates. The vhost crate is being patched with the latest version
from rust-vmm because the version 0.1.0 on crates.io doesn't include the
patches we need yet.

6e63df98ba pci: vfio: Fix and clarify BAR calculation code 
The BAR calculation code was incorrect for calculating I/O BARs but also
has misleading comments (mixing bits and bytes, first and least
significant, etc).

This change adjusts the algorithm to more closely match the version
described in the PCI specification and takes advantage of Rust's binary
literals for ease of reading. Although this is slightly longer by
calculating the 64-bit and 32-bit paths separately I think this is
easier to read.

1f2915bff0 vmm: hypervisor: split set_user_memory_region to two functions 
Previously the same function was used to both create and remove regions.
This worked on KVM because it uses size 0 to indicate removal.

MSHV has two calls -- one for creation and one for removal. It also
requires having the size field available because it is not slot based.

Split set_user_memory_region to {create/remove}_user_memory_region. For
KVM they still use set_user_memory_region underneath, but for MSHV they
map to different functions.

This fixes user memory region removal on MSHV.

933d41cf2f vmm: Provide DMA mapping handlers to virtio-mem devices 
Now that virtio-mem devices can update VFIO mappings through dedicated
handlers, let's provide them from the DeviceManager.

Important to note these handlers should either be provided to virtio-mem
devices or to the unique virtio-iommu device. This must be mutually
exclusive.

080ea31813 pci, vmm: Manage VFIO DMA mapping from DeviceManager 
Instead of letting the VfioPciDevice take the decision on how/when to
perform the DMA mapping/unmapping, we move this to the DeviceManager
instead.

The point is to let the DeviceManager choose which guest memory regions
should be mapped or not. In particular, we don't want the virtio-mem
region to be mapped/unmapped as it will be virtio-mem device
responsibility to do so.

acfbee5b7a interrupt: Make notifier function return Option<EventFd> 
In anticipation for supporting the notifier function for the legacy
interrupt source group, we need this function to return an EventFd
instead of a reference to this same EventFd.

The reason is we can't return a reference when there's an Arc<Mutex<>>
involved in the call chain.

We need to be able to return the barrier from the code that prepares to
activate the virtio device. This triggered by a write to the
configuration fields stored in the PCI BAR. Since bars can be accessed
by both memory mapping and through PCI config I/O several prototypes
must be changed.

1fc6d50f3e misc: Make Bus::write() return an Option<Arc<Barrier>> 
This can be uses to indicate to the caller that it should wait on the
barrier before returning as there is some asynchronous activity
triggered by the write which requires the KVM exit to block until it's
completed.

This is useful for having vCPU thread wait for the VMM thread to proceed
to activate the virtio devices.
