Probably question to Kevin,
I've tried to make AP bootstrap run in parallel
to speed up smp_setup with many CPUs.
However it hangs and I couldn't debug it.
Debugging works fine in 16bit mode as described in wiki
but from the point when entry
Changelog since:
v1:
* s/count_cpu/apic_id_init/
* merge handle_x2apic() into apic_id_init()
RFC:
* move out max-cpus check out of mptable_setup()
* factor out CPU counting/apic ID detection in separate function
* return back accidentially deleted debug message with APIC ID
MPTable doesn't support more than 255 CPUs and
QEMU supplies an alternative MADT table which
guest will use instead of it. So do not install
legacy tables if more than 254 CPUs are provided

v2:
* s/count_cpu/apic_id_init/
* call apic_id_init() after sending SIPI,
it will be needed for switching BSP into x2APIC mode

1 file changed,
SDM[*1] says that if there are CPUs with APIC ID
greater than 254, BIOS is to pass control to OS
in x2APIC mode. Use the fact that QEMU passes in
"etc/max-cpus" max possible "APIC ID + 1" to
detect need for x2APIC mode. Also instead of
CMOS_BIOS_SMP_COUNT which is limited to 256 CPUs
use a new rom
MaxCountCPUs could never be 0 or less CountCPUs
anymore, remove code that wouldn't be executed.
