SYS_NUM_MSI is the number of available system MSIs. OpenSBI and the Linux wired-MSI domain therefore treat valid system MSI indices as the half-open range [0, SYS_NUM_MSI). The driver stores this count in nr_irqs, but its translation callback only subtracts gsi_base. For DT, gsi_base is zero, so an interrupt specifier at or above SYS_NUM_MSI can be retained as the hardware interrupt number. The wired MSI allocation path uses a separate descriptor index and preserves the hardware number in the MSI cookie, so the domain size does not reject it. Reject a raw value below gsi_base and a translated value outside that half-open range.
