* service: sm/kernel/loader: Implement QueryPointerBufferSize, automatic ↵JPikachu2025-04-301-2/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | pointer buffer sizing, and SM service improvements This commit introduces multiple improvements to IPC handling and system management services, enhancing game compatibility and emulator stability. --- 1. Fully Implemented QueryPointerBufferSize Service: - Exposes the per-process IPC pointer buffer size through `QueryPointerBufferSize` instead of returning stubbed values. - Added `m_pointer_buffer_size` field to `KProcess`, initialized with a safe default (0x8000). - Introduced getter and setter methods (`GetPointerBufferSize()` / `SetPointerBufferSize()`). - Registered new handler in `sm_controller` for handling QueryPointerBufferSize requests. - Ensures accurate buffer size reporting for games relying on this service. --- 2. Automatic Pointer Buffer Sizing Per-Game: - Automatically determines heap size by parsing `main.npdm` from the game’s ExeFS: - Heap size > 1 GiB → pointer buffer size set to `0x10000`. - Heap size > 512 MiB → pointer buffer size set to `0xC000`. - Otherwise, defaults to `0x8000`. - Gracefully handles missing or malformed `main.npdm` by falling back to default settings. - Automatically configures pointer buffer size during `AppLoader_NCA::Load`. - Added logging for heap size detection and buffer size configuration for easier debugging. --- 3. SM Service Improvements: - Added full implementation of `QueryPointerBufferSize` within the SM service framework. - Cleaned up stubbed methods and ensured correct domain handling. - Registered new service commands (e.g., `SetPointerBufferSize` and `QueryPointerBufferSize`) in `sm_controller`. - Improved session handling with proper conversion to domain objects where necessary. --- Benefits: - Greatly improves compatibility with games that require larger IPC pointer buffers - Eliminates the need for manual per-game pointer buffer overrides. - More accurate emulation of Switch system services, improving stability for both commercial titles and homebrew. - Provides cleaner logging for easier debugging and maintenance. - Future-proofs IPC handling for upcoming titles with higher memory demands. --- Additional Notes: - Default pointer buffer size remains 0x8000 for smaller titles or if heap size cannot be determined. - Falls back to safe defaults without affecting overall emulator performance. - All new service calls properly registered and integrated without breaking existing functionality.

* loader: Resolve instances of variable shadowingLioncash2021-04-271-11/+28
| | | | | Eliminates variable shadowing cases across all the loaders to bring us closer to enabling variable shadowing as an error in core.

* core/loader: Remove dependencies on the global system instanceLioncash2020-09-161-3/+3
| | | | | | | | | Now all that remains is: 18 instances in file_sys code 14 instances in GDB stub code (this can be tossed wholesale) 4 instances in HLE code 2 instances in settings code.

* core/core: Move process execution start to System's Load()Lioncash2019-04-111-12/+14
| | | | | | | | | This gives us significantly more control over where in the initialization process we start execution of the main process. Previously we were running the main process before the CPU or GPU threads were initialized (not good). This amends execution to start after all of our threads are properly set up.

| | | | | | | | | | a SharedPtr A process should never require being reference counted in this situation. If the handle to a process is freed before this function is called, it's definitely a bug with our lifetime management, so we can put the requirement in place for the API that the process must be a valid instance.
