Multi thread, where to start?

[WEREMSOFT]

I'd like to create a simple thread that do something in another core, in Pure64 I can see that the other cores are initialized. Does the kernel provides some functionality to execute, lets say, a function in another core?

Just a quick note first - BareMetal does not support multi-threading in the conventional sense. Multi-core is supported based on the available hardware (as well as "virtually" via Intel HyperThreading). So if your system has 8 CPU Cores you can execute 8 things concurrently.

smptest.asm is a very small example of this.

; b_smp_set -- Set a specific CPU to run code
;  IN:	RAX = Code address
;	RCX = CPU APIC ID
; OUT:	RAX = 0 on error
; Note:	Code address must be 16-byte aligned

b_system is called with smp_set to set a CPU core to run code.
