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.
