andi,
In LinuxBIOS, we don't set the MPS 0x467 and the AP still can be started by BSP.
are these really needed for x86_64?
Dprintk("Setting warm reset code and vector.\n");
CMOS_WRITE(0xa, 0xf);
local_flush_tlb();
Dprintk("1.\n");
*((volatile unsigned short *) phys_to_virt(0x469)) = start_rip >> 4;
Dprintk("2.\n");
*((volatile unsigned short *) phys_to_virt(0x467)) = start_rip & 0xf;
Dprintk("3.\n");
the STARTUP IPI should work well with MPS v1.4
