Hi, Julien! During bringing up Xen on Renesas Lager board we faced with problem. A lot of Xen sources relies on statement, that IRQ number is less then 256 and variables, parameters, fields etc. are of type uint8_t. But we can have IRQs, that are greater then 255, for example on RCar H2 SoC. Also, as I saw from one of your latest commits, GICv supports 1020 physical interrupts. As a result, overflow can occur. So it seems logical to increase all irq staff to uint16_t or uint32_t. We have local patches for increasing some structures, functions etc. But before pushing these patches I want to know your opinion, what do you think about this problem? What type should we use uint16_t or uint32_t? How to find all places where uint8_t type is used for IRQ?
