MADT is used to specify the GSI base for each IO-APIC and the number of interrupt pins per IO-APIC is programmed into Max. Redir. Entry register of that IO-APIC. On platforms with multiple IO-APICs, there can be holes in the GSI space. For example, on a platform with 2 IO-APICs, the following configuration has a hole (from 24 to 31) in the GSI space. IO-APIC 1: GSI base - 0, number of pins - 24 IO-APIC 2: GSI base - 32, number of pins - 8 This patch also adjusts the size for variables used to represent the total number of IO-APICs on the system from uint16_t to uint8_t as the ACPI MADT uses only 8-bits to indicate the unique IO-APIC IDs.
