Revision as of 18:21, 8 April 2016
Cafe OS syscalls are issued by doing the following:
li r0, 0x0100 # load syscall value->r0 sc # syscall instruction blr # return control to program
When you send a call to the kernel, it goes to FFF00C00, which then jumps to FFF021A0 + (fastcall << 5).
Normal syscalls are divisible by 0x100, so all of them will jump to FFF0021A0 itself, which is a jump to the table dispatcher.
The dispatcher uses the RAMPID and syscall it was sent to load an address from its table which it then jumps to (which, if zero, just crashes as it's invalid).
Below is all RAMPIDs' access to syscalls. The loader mostly has its own special variations of syscalls.
RAMPID 1, system (home menu, browser, and error handler), and apps/games usually all have access to the same syscalls.
