- Thread-topic: [PATCH 06/10] xen/arm/irq: allow eSPI processing in the do_IRQ function
The do_IRQ() function is the main handler for processing IRQs.
Currently, due to restrictive checks, it does not process interrupt
numbers greater than 1024. This patch updates the condition to allow
the handling of interrupts from the eSPI range.
