But there is a problem, when QEMU initialize GICv3, it will check the variable `num_irq <= 1020 && (num_irq & 32) == 0`, which will lead to error abort. So there is no way to bypass the ```num_irq <= 1020``` check and we cannot use irq number bigger than 992 while in ARM GIC specification, irq number < 1020 should all be aviliable to use.""" +reproduce = "n/a" +additional = "n/a" |
