| |
With the current range specified for the CPU interface there is an error message at boot:
GIC: GICv2 detected, but range too small and irqchip.gicv2_force_probe not set
Setting irqchip.gicv2_force_probe=1 in bootargs results in:
GIC: Aliased GICv2 at 0x0000000010320000, trying to find the canonical range over 128kB GIC: Adjusting CPU interface base to 0x000000001032f000 GIC: Using split EOI/Deactivate mode
Using the adjusted CPU interface base and 8K size results in only the final line remaining and fully working system as well as /proc/interrupts showing additional IPI3,4,5,6:
IPI3: 0 0 CPU stop (for crash dump) interrupts IPI4: 0 0 Timer broadcast interrupts IPI5: 0 0 IRQ work interrupts IPI6: 0 0 CPU wake-up interrupts
