Reto Buerki c7cadf52a6 hw_x86_64: setup ISR and IDT ... * Add isr.s assembler file: The file declares an array of Interrupt Service Routines (ISR) to handle the exception vectors from 0 to 19, see Intel SDM Vol. 3A, section 6.3.1. * Add Idt class: * The class Genode::Idt represents an Interrupt Descriptor Table as specified by Intel SDM Vol. 3A, section 6.10. * The setup function initializes the IDT with 20 entries using the ISR array defined in the isr.s assembly file. * Setup and load IDT in Genode::Cpu ctor: The Idt::setup function is only executed once on the BSP. * Declare ISRs for interrupts 20-255 * Set IDT size to 256		2015-03-27 11:53:18 +01:00
