Implements several IPC commands in IApplicationFunctions related to GPU error
handling and system events:
- EnableApplicationAllThreadDumpOnCrash (cmd 124)
- SetDelayTimeToAbortOnGpuError (cmd 131)
- TryPopFromNotificationStorageChannel (cmd 151)
- SetHdcpAuthenticationActivated (cmd 170)
- GetLaunchRequiredVersion (cmd 180)
- UpgradeLaunchRequiredVersion (cmd 181)
Also adds the LaunchRequiredVersion struct definition to the header file.
These are currently stubbed implementations that log warnings when called.

Reverts overly restrictive storage buffer validation and size calculation
that was causing rendering issues in The Legend of Zelda: Tears of the
Kingdom, particularly in underground/depth areas. The simplified approach:
- Uses GetMemoryLayoutSize() instead of manual page probing
- Removes unnecessary 4GB memory bounds validation
- Streamlines address translation and alignment handling
This fixes numerous reported cases of missing or corrupted rendering in
TOTK's underground areas where storage buffer operations are heavily used
for depth-related effects.
Implements proper reference counting for binder objects based on the official
documentation. This adds both weak and strong reference counting support to
the IBinder interface and its implementations (BufferQueueProducer and
BufferQueueConsumer).
The implementation follows the documented behavior where:
- type 0 affects weak references
- type 1 affects strong references
- During initialization: {addval=1, type=0} followed by {addval=1, type=1}
- For onFirstRef: {addval=1, type=1}
- For onLastStrongRef: {addval=-1, type=1}
Reference counters are implemented using std::atomic to ensure thread safety.

- vi:s sessions can use everything except GetManagerDisplayService
- vi:m sessions can use all commands
REFS: switchbrew.org/wiki/Display_services#IApplicationDisplayService
Removes the save states menu and unused help menu items as they require
additional research and implementation work. Specifically:
- Remove save states menu and associated actions (Save/Load)
as proper implementation requires more research
- Remove unused help menu items:
* Open Mods Page
* Open Quickstart Guide
* Open FAQ
- Keep core help functionality (Report Compatibility and About)
- Reorder menu properties for better organization
This change helps maintain a cleaner UI by removing placeholder
features that are not yet ready for implementation.
Refactors the MM (Memory Management) service implementation with improved:
- Session management using a vector of Session objects instead of global vars
- Type safety with proper enums and member encapsulation
- Error handling with consistent patterns
- Modern C++ features (std::erase_if, std::find_if, emplace_back)
- Logging with detailed debug messages
- Code organization and const correctness
Key changes:
- Add Session class with proper encapsulation
- Add EventClearMode enum (Manual = 0, Auto = 1)
- Update Module enum naming for consistency
- Implement proper session tracking and lookup
- Add detailed parameter logging
- Use modern C++ algorithms for session management
The implementation now properly handles multiple sessions and matches
the documented nn::mmnv::IRequest interface more closely.
Refs: switchbrew.org/wiki/Display_services#mm:u
service/mm: add missing vector include and update copyright
- Add missing <vector> include for std::vector usage
- Add Citron copyright notice
- Maintain existing include ordering
This is a minor cleanup change to ensure proper header inclusion
and copyright attribution.
Add proper type definitions and parameter handling for the Memory Management
(mm:u) service based on the Switch documentation:
- Add Module enum for hardware components (CPU, GPU, EMC, etc)
- Add Priority and Setting type definitions as u32
- Add EventClearMode enum for initialization
- Implement proper parameter handling for all IPC calls
- Add detailed logging with parameter values
The Module enum now properly reflects the documented hardware components:
CPU, GPU, EMC, System Bus, Memory Select, and NVIDIA modules (NVDEC,
NVENC, NVJPG).
This makes the implementation match the documented nn::mmnv::IRequest
interface.

- Redesign loading screen progress bar with gradient animation
- Update loading screen typography using Segoe UI
- Add comprehensive dark theme styling to main window
- Modernize menu, toolbar, and dock widget appearances
Relaxes validation checks in the NVDRV GPU service and improves error notifier
handling to prevent potential hangs. Key changes:
- Remove strict size validation in SetErrorNotifier
- Relax GPFIFO entry count validation to only check for non-zero values
- Add proper error notifier state tracking in GPU class
- Improve debug logging messages
The previous strict validation was causing issues with some games like ACNH.
These changes maintain necessary checks while being more permissive with
edge cases that don't impact functionality.
Technical changes:
- Store error notifier state in GPU class for future implementation
- Remove upper bound check on GPFIFO entries
- Simplify error notifier setup flow
This should resolve hanging issues while maintaining core functionality.
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.
Adds UI elements for future save state support:
- New "Save States" menu in the main menubar
- Save and Load action items with keyboard shortcuts
- No functionality implemented yet, just UI stubs
- Add proper invocation info handling for tessellation and fragment stages
- Return patch vertices info shifted by 16 bits for tessellation stages
- Return sample mask shifted by 16 bits for fragment stage
- Return standard format (0x00ff0000) for compute and other stages
- Implement consistently across SPIRV, GLSL, and GLASM backends
- Remove stubbed warning message
- 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.
Two main changes in this commit:
1. Replace NVIDIA-specific GL_NV_gpu_shader5 extension with the more widely
supported GL_EXT_shader_explicit_arithmetic_types_float16 in the scaleforce
shader. This improves compatibility across different GPU vendors.
2. Refactor ARM32 exception handling:
- Restructure exception cases for better readability
- Update exception handling to match current Dynarmic API
- Fix indentation in switch statement
- Remove AccessViolation case as it's no longer supported in current API
These changes improve shader compatibility and align the exception handling
with the current Dynarmic implementation.
- 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.
Replaces the battery temperature reading implementation with a more
compatible approach using ACTION_BATTERY_CHANGED broadcast intent.
This change provides better backwards compatibility and adds proper
error handling for the temperature reading functionality.
Add stub implementations for previously unhandled flow test conditions in the
shader recompiler's IR emitter. These conditions were previously throwing
"Not Implemented" exceptions when encountered.
The following flow test cases are now stubbed:
- FCSM_TR (Fragment Shader Coarse/Fine Mode Test and Reject)
- CSM_TA (Coarse/Fine Mode Test Accept)
- CSM_TR (Coarse/Fine Mode Test and Reject)
- CSM_MX (Coarse/Fine Mode Maximum)
- FCSM_TA (Fragment Shader Coarse/Fine Mode Test Accept)
- FCSM_MX (Fragment Shader Coarse/Fine Mode Maximum)
Currently these stubs:
1. Return false (ir.Imm1(false)) as a placeholder value
2. Log a warning message indicating the stub
3. Allow shaders using these conditions to compile rather than fail
This is a step toward proper implementation of coarse/fine mode shader
operations. The stubs prevent crashes while making it clear which code paths
need full implementation.
Technical notes:
- Removed the previous FCSM_TR implementation that used flag operations
- Added consistent warning messages for tracking stub usage
- Kept within the existing GetFlowTest switch statement structure
Implements the USE_AUTO_STUB setting in the Android frontend:
- Added USE_AUTO_STUB to BooleanSetting enum
- Added UI switch setting with description in SettingsItem
- Added setting to system settings section in SettingsFragmentPresenter
- Added string resources for setting title and description
The setting allows users to toggle automatic stubbing of missing services
and functions, which may improve compatibility at the cost of stability.
- 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.
- REF: https://switchbrew.org/wiki/HID_services#ActivateGesture
- Replace emoji thermal indicators with modern progress bar UI
- Switch temperature source to battery sensor for better accuracy
- Adjust temperature thresholds (30°C-45°C range)
- Add automatic Vulkan Validation Layer download for Android
The thermal display now shows a visual progress bar with percentage
instead of emojis, making it easier to gauge system temperature at
a glance. Temperature reading now comes from the battery sensor
which is more reliable across devices.
Build system improvements include automated VVL binary downloads
and installation for Android builds when CITRON_DOWNLOAD_ANDROID_VVL
is enabled.
Previously, the code would unconditionally add a constant buffer descriptor
at index 0 whenever storage buffers were present, which could cause conflicts
and crashes. This change:
- Adds validation to check if constant buffer 0 already exists
- Only adds the descriptor if it's not already present
- Prevents potential descriptor conflicts in shaders
This should resolve crashes in Vulkan games related to invalid descriptor
layouts and resource binding conflicts.
Add support for bindless texture constant buffers in the compute pipeline
creation process. When storage buffer descriptors are present, create a
constant buffer descriptor to handle bindless textures. This fixes the
"Failed to track bindless texture constant buffer" error.
Changes:
- Add constant buffer descriptor with index 0 and count 1 when storage
buffers are present
- Place descriptor creation before SPIR-V code generation to ensure proper
shader compilation
This resolves issues with bindless texture access in compute shaders.
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.
Updates the Discord Rich Presence implementation to use Tinfoil's media
server for game images and improves the overall presentation.
Technical changes:
- Switch to Tinfoil media server for game images
- Add proper title ID handling and display
- Improve error handling for image requests
- Increase network timeout to 10 seconds
- Cache URL to prevent string destruction
- Update Discord client ID
- Clean up code formatting and organization
UI/UX improvements:
- Remove title ID from game state display
- Update default text to be more descriptive
- Improve error logging for failed image fetches
- Maintain image persistence between updates
This change provides better game image support and a cleaner Discord
presence display while improving reliability of the integration.
Replace hardcoded 128-byte alignment with a defined CACHE_LINE_SIZE constant
of 64 bytes for the atomic indices in RingBuffer. This value is more
appropriate for most modern CPU architectures and simplifies the
implementation by using a consistent value regardless of compiler support
for hardware_interference_size.
Changes:
- Add CACHE_LINE_SIZE constant set to 64 bytes
- Use CACHE_LINE_SIZE for atomic index alignment in both code paths
- Remove outdated TODO comment about hardware_destructive_interference_size
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
Added two new audio feature support tags with their corresponding revision
numbers:
- AudioCompressorStatistics (rev 16): For tracking compressor statistics
- AudioVolumeResetSupport (rev 17): For volume reset functionality
These features align with the documented Nintendo Switch audio service
capabilities and maintain compatibility with the existing feature support
system.
Fixes the StorageBufferBinding function to properly handle memory validation
and size detection. Key changes include:
- Fix ReadBlock usage to properly handle void return values
- Implement safer memory validation using byte-level reads
- Improve size detection logic for storage buffers
- Fix NVN buffer size reading
- Add proper bounds checking for device memory addresses
- Add better error logging for invalid conditions
This addresses the "Failed to find storage buffer for cbuf index 0" errors
by implementing more robust memory validation and size detection. The changes
ensure proper handling of invalid memory addresses and prevent crashes from
accessing out-of-bounds memory.
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.
- Modify DmaPusher to use safe memory reads when handling compute
operations at High GPU accuracy
- Prevent potential memory corruption issues that could lead to
invalid dispatch parameters
- Previously, unsafe reads could result in corrupted launch_description
data in KeplerCompute::ProcessLaunch, causing invalid vkCmdDispatch
calls
- By enforcing safe reads specifically for compute operations, we
maintain performance for other GPU tasks while ensuring compute
dispatch stability
This change requires >= High GPU accuracy level to take effect.
Simplifies the negative reciprocal calculation in FSWZADD by using the
dedicated FPRecip operation instead of manually constructing a division.
This change:
- Replaces FPDiv(Imm32(f32(1.0f)), src_b) with FPRecip(src_b)
- Results in more efficient code for calculating 1.0/x
- Fixes build errors from undefined IR emitter methods
Fixes incorrect method names in the floating point swizzled add implementation:
- FNeg -> FPNeg
- FDiv -> FPDiv
- FImm32(1.0f) -> Imm32(ir.f32(1.0f))
These changes align with the correct IR emitter interface naming conventions,
where floating-point operations use the 'FP' prefix and immediate values are
properly constructed using f32().
Implements the Internal Stage Buffer Entry Read (ISBERD) instruction in the
Maxwell shader recompiler. This replaces the previous stubbed implementation
with actual buffer reading functionality.
The implementation:
- Validates unsupported features (skew, o, mode, shift)
- Performs buffer read using IR::InternalStageBufferRead
- Stores the read value to the destination register
This removes the "(STUBBED) called" warning messages that were previously
being logged during shader compilation.
Implements the ISBERD (Internal Stage Buffer Entry Read) instruction's
mode and shift options that were previously throwing NotImplemented
exceptions. This includes:
- Patch mode for reading patch data
- Prim mode for reading primitive data
- Attr mode for reading attribute data
- U16 shift for 16-bit unsigned values
- B32 shift for 32-bit values
The implementation follows Maxwell's ISA specification for handling
different buffer read modes and data shifts.
Added new feature support tags to track audio functionality across firmware
versions. Changes include:
- Added Audio Out/In Auto buffer support tags (3.0.0+)
- Added Final Output Recorder features including work buffer (3.0.0+, 9.0.0+)
- Added Audio Renderer features like manual execution and voice drop
- Added Audio Device features including notifications and auto volume
- Added Hardware Opus decoder features including large frame support
- Added System Audio features like master volume and hearing protection
This provides more complete feature detection for audio functionality
introduced in firmware versions 3.0.0 through 19.0.1.
