39 * IDT vectors, but all other device interrupts allocate IDT vectors
40 * on demand. Currently we have 191 IDT vectors available for device
41 * interrupts on each CPU. On many systems with I/O APICs, a lot of

45 * The first 16 IRQs (0 - 15) are reserved for ISA IRQs. Interrupt
46 * pins on I/O APICs for non-ISA interrupts use IRQ values starting at
73 * "turn on" the interrupt on the CPU side by setting up an IDT entry, and
101 * An interrupt source. The upper-layer code uses the PIC methods to
102 * control a given source. The lower-layer PIC drivers can store additional
