Hi Thomas,
Sorry to bother you. I am always wondering what's the difference between x86_cpu_to_apicid and x86_bios_cpu_apicid. Or in other words, I don't know why x86_bios_cpu_apicid is required. From code both x86_cpu_to_apicid and x86_bios_cpu_apicid stores the apicid correspond to a certain logic cpu number. With my understanding x86_cpu_to_apicid can do what x86_bios_cpu_apicid is doing except for its usage in below commit.
commit 1f12e32f4cd5243ae46d8b933181be0d022c6793 Author: Thomas Gleixner <tglx@linutronix.de> Date: Mon Feb 22 22:19:15 2016 +0000
x86/topology: Create logical package id
Could you please help to explain when it's convenient to you?
Thanks Baoquan
