Setup needed to use pass-through PCI devices

If you want to use any pass-through PCI devices with this updated hypervisor version, you need to modify your host buildfile and your VM configuration.

In your host buildfile, add the following library file and binary:
# PCI Multiplexer Client API
/lib/libpci_mux.so=libpci_mux.so

# PCI Multiplexer Service, used by QNX Hypervisor
/sbin/pci-connector=pci-connector
Then, run the PCI multiplexer service (which is included with QNX Hypervisor) by adding the following to the startup script, at any time after pci-server is started:
# Start PCI Multiplexer service for QNX Hypervisor
# Note that the -n option determines what path a guest configuration should
# use with its "set pci-mux-path /dev/<insert -n argument here>" option
# to enable any host PCI devices that are to be passed through to the guest
# (e.g. "set pci-mux-path /dev/pci_mux").
pci-connector -n pci_mux
In the configuration of the VM that will pass through the devices to the guest, ensure the path for /dev/pci_mux matches that in the -n option passed to pci-connector above. Add the following lines (in addition to your PCI pass-throughs, whatever those might be):
set pci-mux-path /dev/pci_mux

Updates and fixed issues

Description Applicable Architecture(s) Application-Level Impact System-Level Impact Reference Number
Support for memory-mapped and system registers has been added for guests that use GIC version 2. AArch64 None To use GIC version 2, add this line to the VM configuration: vdev gic version 2 2988683
The pass sched VM configuration option has been fixed to set the pulse priority for interrupts. General None None 2984876
The guest power state implementation has been fixed so the correct code runs when the conditions configured for power state notification are met. AArch64 None None 2984456
