- Update vcpkg baseline to a42af01b72c28a8e1d7b48107b33e4f286a55ef6
- Add SPIRV-Tools and SPIRV-Headers as submodules
- Update Vulkan-related submodules to latest stable versions
- Improve memory access error handling:
- Add specific handling for null pointer accesses in ARM32 emulation
- Return 0 for null pointer reads instead of undefined behavior
- Silently ignore writes to null pointers
- Add more detailed error messages distinguishing between null pointer
access and other unmapped memory errors
- Treat addresses below 0x1000 as potential null pointer accesses
These changes should provide more graceful handling of null pointer
accesses and improve stability when running games that attempt invalid
memory operations.
- 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.
Adds support for InfoType::SystemResourceSize (0x1C) which is required for
proper initialization of the Virtual Address Memory Manager (VAMM). This
implementation:
1. Adds SystemResourceSize to the InfoType enum in svc_types.h
2. Implements the GetInfo handler for SystemResourceSize in svc_info.cpp
3. Returns 512MB (0x20000000 bytes) as the system resource size
4. Adds debug logging for the SVC call
The 512MB value is chosen based on typical system resource allocations
needed for VAMM initialization on the Nintendo Switch.
This fixes crashes in games that rely on VAMM functionality, particularly
during nn::os::detail::VammManager::InitializeIfEnabled().
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
- Add Memory_10Gb and Memory_12Gb to MemoryLayout enum
- Update memory layout settings to support up to 12GB
- Add SMC enums for 10GB and 12GB memory sizes and arrangements
- Increase MainMemorySizeMax from 8GB to 12GB
- Add memory pool size calculations for 10GB and 12GB configurations
- Update UI translations for new memory options
Adds logic to track and skip duplicate consecutive addresses when logging
backtraces. This improves log readability by removing redundant entries
that point to the same address in sequence.
Updates version constants to match Nintendo Switch firmware 19.0.1:
- HOS version numbers (19.0.1)
- Version hash
- Display version string
- Display title string
- The personalization array in GenerateTelemetryId() was too small (18 bytes)
for the string "citron Telemetry ID" which requires 20 bytes including the
null terminator
- Increased the array size to 20 to properly accommodate the full string
