Add a hack to work around a bug in VBox: The APIC emulation requires an iret instruction following closely after writing the EOI register. Since we return from kernel mode traps with a jmp (yes you can return from an interrupt with a jmp!) the EOI is never triggered, making VBox believe we are still serving the interrupt and keeping the PPR on high level, preventing following interrupts. A small asm stub now does the work of both writing the EOI and doing an iret. svn path=/trunk/; revision=53665 |
