On a Raspberry Pi 4B running QNX 8.0.0 with hypervisor enabled, an Ubuntu Linux 20.04.1 guest kernel panics early in the boot process, when trying to set up the GICv3, which is virtualized on top of the v2 hardware of the BCM2711.
GICv2 support has been restored in Hypervisor 8.0 build 549 (published on June 12, 2025), and is available to download via QNX Software Center.
Please refer to the release notes for this specific release:
---------- Support for memory-mapped and system registers has been added for guests that use GIC version 2.
To use GIC version 2, add this line to the VM configuration:
vdev gic version 2 ----------
To resolve this issue, please upgrade to the latest hypervisor version ( >= build 549) via QNX Software Center, and run a test with the above recommended change to the qvm config file.
NOTE: This entry has been validated against the SDP version listed above. Use caution when considering this advice for any other SDP version. For supported releases, please reach out to QNX Technical Support if you have any questions/concerns.
