He(he)llo !

Just looking for documentation this time :D

Where can I find the IRQ number list ???

I'd like tyo use the syscall 0x10 (#16)

Code: Select all

 
AddIntcHandler&#40;
     a0=Interrupt_Signal, 
     a1=Interrupt_Handler, 
     a2=? &#40;0 seems to be used...&#41;
&#41;;

I understood that Interrupt_Signal could be :
0x1 = HBL (true ?)
0x2 = VBL start
0x3 = VBL end

So those are only GS signals (yep ? more ?)

Where all those interrupts signals are documented ?

According ps2lib it is
s32 AddIntcHandler(s32 cause, s32(*handler_func)(s32 cause), s32 next);
However I don't know meaning of "next" arg.

Btw here is my suggestions about INTC.

0 - GS
1 - SBUS
2 - vblank start
3 - vblank end
4 - VIF0
5 - VIF1
6 - VU0
7 - VU1
8 - IPU
9&10 - some timers
