- Thread-topic: [PATCH v5 06/12] xen/arm/irq: allow eSPI processing in the gic_interrupt function
The gic_interrupt function is the main handler for processing IRQs.
Currently, due to restrictive checks, it does not process interrupt
numbers greater than 1019. This patch updates the condition to allow
the handling of interrupts from the eSPI range.
