ldr:shel
This is "nn::ldr::detail::IShellInterface".
| Cmd | Name |
|---|---|
| 0 | #SetProgramArgument |
| 1 | #FlushArguments |
SetProgramArgument
Takes a type-0x9 input buffer with launch arguments (as string), an u32 (size of arguments string), and an input title-id.
Loads a process for the specified title-id and passes along the supplied arguments. Loaded processes are kept in a queue waiting for PM to launch them. The maximum number of waiting processes in this list is 10.
FlushArguments
Clears the loaded processes waiting queue.
ldr:dmnt
This is "nn::ldr::detail::IDebugMonitorInterface".
| Cmd | Name |
|---|---|
| 0 | #SetProgramArgument |
| 1 | #FlushArguments |
| 2 | #GetProcessModuleInfo |
GetProcessModuleInfo
Takes in a u64 Process ID, and a C descriptor out array of #ModuleInfos. Returns the number of ModuleInfos copied to output.
ModuleInfo is the same here as for ro:dmnt.
ModuleInfo has the following layout:
ModuleInfo
| Offset | Size | Description |
|---|---|---|
| 0x0 | 0x20 | Build ID |
| 0x20 | 0x8 | Mapped Address |
| 0x28 | 0x8 | Mapped Size |
ldr:pm
This is "nn::ldr::detail::IProcessManagerInterface".
| Cmd | Name |
|---|---|
| 0 | CreateProcess |
| 1 | #GetProgramInfo |
| 2 | #PinProgram |
| 3 | #UnpinProgram |
GetProgramInfo
Takes an ncm::ProgramLocation, parses the NPDM, and writes a #ProgramInfo to a C descriptor buffer as follows:
ProgramInfo
| Offset | Size | Description |
|---|---|---|
| 0x0 | 0x1 | MainThreadPrio. Arg1 to svcStartProcess |
| 0x1 | 0x1 | DefaultCpuId. Arg2 to svcStartProcess |
| 0x2 | 0x1 | ApplicationType, see here. |
| 0x3 | 0x1 | Padding |
| 0x4 | 0x4 | MainThreadStackSize. Arg3 to svcStartProcess |
| 0x8 | 0x8 | TitleIdRange_Min |
| 0x10 | 0x4 | ACID Service Access Control list size |
| 0x14 | 0x4 | ACI0 Service Access Control list size |
| 0x18 | 0x4 | ACID FS Access Control buffer size |
| 0x1C | 0x4 | ACI0 FS Access Control buffer size |
| 0x20 | <Varies> | ACID Service Access Control list |
| <Varies> | <Varies> | ACI0 Service Access Control list |
| <Varies> | <Varies> | ACID FS Access Control buffer |
| <Varies> | <Varies> | ACI0 FS Access Control |
PinProgram
Takes an ncm::ProgramLocation, returns a u64 "PinId".
UnpinProgram
Takes a PinId from #PinProgram.
