Implements several previously stubbed functions in the NVDRV service:
- Initialize proper transfer memory handling
- Add error notifier configuration
- Implement channel timeout and timeslice management
- Add object context allocation and tracking
- Add GPU interface stubs for new functionality
The changes improve the accuracy of GPU-related operations while maintaining
compatibility with the existing codebase. All functions now properly validate
parameters and handle endianness correctly using _le types.
- The GetManagerDisplayService function in IApplicationDisplayService is fully implemented, so remove the stubbed warning and change the log level to DEBUG to match its implementation status.
- Updated the QueryPointerBufferSize function to return the correct u16 pointer buffer size.
- Ensured the function logs its call at the debug level.
- Used IPC::ResponseBuilder to construct the response with the correct buffer size.
This change addresses the stubbed implementation and ensures compliance with the HIPC protocol.
- Added the SetGestureOutputRanges function to the IHidServer class to address the unimplemented function '92' error.
- This fix was discovered through log analysis, which showed a critical assertion failure in the HID service for an unknown function '92'.
- The log indicated a userspace panic and backtrace, pointing to the need for implementing this function to prevent execution breaks.
- Updated CMakeLists.txt to remove specific version requirements for several packages, enhancing flexibility.
- Updated subproject commit references for VulkanMemoryAllocator and vcpkg.

updated to include "Citron Homebrew Project" across multiple files, regardless
of whether any contributions were made.
- This commit removes the incorrect attribution and reverts the copyright header
to its previous state.
- Copyright attribution should only be added when meaningful contributions have
been made to the file.
- This commit ensures proper compliance with copyright standards and maintains
correct attribution to the respective contributors.
- Special thanks to Tachi for pointing out the need for these corrections and
ensuring that proper attribution practices are followed.
Add conditional compilation directives to handle packed struct definitions
differently between MSVC and other compilers. MSVC uses #pragma pack
while GCC/Clang use __attribute__((packed)). This change affects:
- ZBCColorEntry
- ZBCDepthEntry
- IoctlZbcSetTable
The functionality remains the same, but ensures proper struct packing
across different compiler environments.
This commit makes several improvements to device memory management and buffer
queue handling:
DeviceMemoryManager:
- Add null pointer and size checks for ReadBlock
- Fill unmapped memory with a known pattern (0xCC) instead of zeros
- Add better error logging for invalid memory accesses
- Add null pointer check for source pointer in memcpy
BufferQueueProducer:
- Improve error handling in WaitForFreeSlotThenRelock
- Add proper abandoned state checking during wait conditions
- Clean up and simplify buffer scanning logic
- Improve logging messages with more descriptive information
- Remove redundant buffer count validation
- Fix potential infinite loop condition during wait
These changes improve stability and error handling while making the code more
maintainable and debuggable. The use of a known pattern for unmapped memory
helps identify uninitialized memory access issues.
Implements TryPopFromFriendInvitationStorageChannel to properly handle
friend invitation data storage and retrieval. This includes:
- Add ResultNoData error code to am_results.h
- Add friend_invitation_storage_channel storage queue to Applet struct
- Implement proper data handling in TryPopFromFriendInvitationStorageChannel
The implementation now properly manages a queue of friend invitation data
and returns appropriate results based on data availability.
Resolves a build failure caused by a mismatch between the defined and expected size of the `IoctlZbcSetTable` structure in `nvhost_ctrl_gpu`. The `static_assert` incorrectly expected the size to be 44 bytes, while the actual size was 48 bytes.
Changes include:
- Updated `static_assert` to correctly reflect the 48-byte size of `IoctlZbcSetTable`.
- Verified packing and alignment to ensure compliance with hardware specifications.
- Reviewed and confirmed correctness of `u32` type definitions.
This fix addresses a regression introduced in commit 9be4bf9aa5, which implemented ZBCSetTable functionality, and ensures successful compilation and adherence to the ZBC table implementation's design.
Implements basic Zero Bandwidth Clear (ZBC) table support in nvhost_ctrl_gpu.
This adds storage and validation for both color and depth clear values,
replacing the previous stub implementation. ZBC is a hardware optimization
technique used by NVIDIA GPUs to efficiently handle buffer clearing operations.
Changes include:
- Added ZBC table storage structures
- Implemented parameter validation
- Added separate handling for color and depth modes
- Improved debug logging
- Added documentation explaining ZBC functionality
