Hi Thomas, Jason
I've a question about nr_irqs(with CONFIG_SPARSE_IRQ enabled) on arch arm64, and want to ask for your suggestions.
The nr_irqs is set to NR_IRQS by default and NR_IRQS is small(64). Arch/arm platforms will re-set nr_irqs to a larger value. I didn't find similar way for arm64. The way I can think of is to redefine NR_IRQS. But according comments in include/asm-generic/irq.h, NR_IRQS should not be a large value. so what's the preferred way to extend nr_irqs, for arm64 specifically? Thanks in advance.
Best Regards Qiao
