Cafe OS syscalls
Revision as of 07:30, 9 April 2016 by NWPlayer123 (talk | contribs) (TODO: Not actually sure which RAMPID system it uses, I assume Browser is always 4? Also, "OS" prefix is only for userspace symbols eg coreinit to mark what is a syscall)
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 a RAMPID and the syscall table at FFEAAA40 (5.5.0) to get the secondary table each RAMPID is able to access.
0 (Kernel), 2, and 3 all use the empty table, root.rpx has its own table with a few unique calls, RAMPID 4, 5, and 6 share "syscall_system", and apps/games (RAMPID 7) have their own. See Cafe OS wiki page for more info.
Below is a list of what all of them, as well as the loader which has its own barebones table, have access to call.
