- Errors-To:
- linux-arm-kernel-bounces+linux-arm-kernel=archiver.kernel.org@lists.infradead.org
- 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
