Detailed Description

interrupt_handler() Interrupt handler

Variable Documentation

interrupt_entry

void* const interrupt_entry[]

Array of function pointer to the default low-level interrupt handlers.

The index corresponds to the vectors entry function, e.g. interrupt_entry[6] points to interrupt_entry_6, handling the trap for invalid opcode.

The entry functions and this array are defined in assembly in interrupt/handler.asm and used in kernel_init() to initialize the Interrupt Descriptor Table (IDT).
