Meta core internal interrupts (from HWSTATMETA and friends) are vectored onto the TR1 core trigger for the current thread. This is demultiplexed in irq-metag.c to individual Linux IRQs for each internal interrupt. External SoC interrupts (from HWSTATEXT and friends) are vectored onto the TR2 core trigger for the current thread. This is demultiplexed in irq-metag-ext.c to individual Linux IRQs for each external SoC interrupt. The external irqchip has devicetree bindings for configuring the number of irq banks and the type of masking available.
