Hi, Rafael, Lv

May I ask for your help.

Recently, I am very confused about the generation of the MADT
in ACPI table.

1: Why we put all the Apic Ids which flag==1 in front of the
one which flag==0 in MADT?

Just like that:

-----orginal-----------------MADT-------
Apic Id	Enable Flag	Apic Id	Enable Flag
0x00	1		0x00	1
0x02	1		0x02	1
0x04	0		0x10	1
0x06	0		0x12	1
0x10	1		0x04	0
0x12	1		0x06	0
0x14	0		0x14	0
0x16	0		0x16	0

If the flag is the same, It will not change the order.

-----orginal-----------------MADT---------
Apic Id	Enable Flag	Apic Id	Enable Flag
0x00	0		0x00	0
0x02	0		0x02	0
0x04	0		0x04	0
0x06	0		0x06	0
0x10	0		0x10	0
0x12	0		0x12	0
0x14	0		0x14	0
0x16	0		0x16	0


2: If the order rule can be changed ?
If it can be done, What should I do?

Thanks,
Liyang.
