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
Line 8:
Line 8:
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.+
Normal syscalls are divisible by 0x100, so all of them will jump to FFF0021A0 itself, which is a jump to the table dispatcher.
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).
+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#Processes|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.
