![]() GIC CPU interfaces versions predating GIC v4.1 were not built to accommodate vINTID within the vSGI range; as reported in the GIC specifications (8.2 "Changes to the CPU interface"), it is CONSTRAINED UNPREDICTABLE to deliver a vSGI to a PE with ID_AA64PFR0_EL1.GIC < b0011. Check the GIC CPUIF version by reading the SYS_ID_AA64_PFR0_EL1. Disable vSGIs if a CPUIF version < 4.1 is detected to prevent using vSGIs on systems where they may misbehave.
