Is there any source out there that I could check?

Does it have to be asm?
from
ps2cam_rpc.c :
Code: Select all
...
DI();
ee_kmode_enter();
iop_addr = (int *)(0xbc000000+ret[1]);
memcpy(&campacket[0],iop_addr, ret[0]);
ee_kmode_exit();
EI();
...

Forgive me if this isn't possible, but why not compile some code setting to kernel mode, and then disassemble it to see what it looks like in ASM?
Why does it specifically need to be in asm anyway? The PS2 SDK supports ASM embedded inside the C++ code.

Go look at ee_kmode_enter, it's all inline asm anyway.
