Inputs are read from registers starting from r0 and outputs are written back to the same registers (also starting with r0).

ID	Name	Inputs	Outputs
0x01	ControlMemory	`r0`: `MemoryOperation operation` `r1`: `u32 addr0` `r2`: `u32 addr1` `r3`: `u32 size` `r4`: `MemoryPermission permissions`	`r0`: `Result` `r1`: `u32 addr_out`
0x02	QueryMemory	`r2`?: `u32 addr`	`r0`: `Result` `r1`: `u32 base_process_virtual_address` `r2`: `u32 size` `r3`: `u32 permission` `r4`: `MemoryState state` `r5`: `PageFlags page_flags`
0x03	ExitProcess	None	None
0x04	GetProcessAffinityMask	`r0`: `[out] u8* affinitymask` `r1`: `Handle process` `r2`: `s32 processorcount`	`r0`: `Result`
0x04	SetProcessAffinityMask	`r0`: `Handle process` `r1`: `[in] u8* affinitymask` `r2`: `s32 processorcount`	`r0`: `Result`
0x05	GetProcessIdealProcessor	`r1`?: `Handle process`	`r0`: `Result` `r1`: `s32 processorid`
0x1B	SetTimer	Timer handle, initial_low, interval_low, initial_high, interval_high	Result
0x2D	ConnectToPort	??, pointer to port name	Result, handle to KClientSession
0x32	SendSyncRequest	handle to KClientSession	Result
