%w means 'word'.

    static inline void PortWrite32(uint16_t port, uint32_t value) {
        __asm volatile("outl %w0, %w1" : : "a" (value), "d" (port));
    }

    static inline uint32_t PortRead32(uint16_t port) {
        uint32_t ret;
        __asm volatile("inl %w1, %w0" : "=a" (ret) : "d" (port));
        return ret;
    }
