- Add maximum memory size limit of 512GB (Overkill)
- Implement additional safety checks for memory mapping:
* Validate non-zero addresses
* Verify address alignment
* Add length validation against maximum size
- Remove redundant assertion for host_offset alignment
- Remove potentially problematic mapping verification
- Improve error logging for invalid mapping attempts
These changes enhance memory safety by adding proper bounds
checking and validation before performing memory mappings,
while removing a potentially problematic post-mapping
verification step.

Renames 'size' parameter to 'length' in IsValidMapping() methods to avoid
conflicts with Android NDK macros that define 'size'. This fixes compilation
issues on Android platforms where the 'size' macro is defined.
|
|
Implements several improvements to memory handling and validation:
- host_memory: Add IsValidMapping() and IsDirectMappingEnabled() methods to
validate memory access
- host_memory: Fix virtual base offset calculation to use proper pointer
arithmetic
- host_memory: Add size field to track allocation size
- nvhost_ctrl_gpu: Return InvalidState instead of InvalidValue for TPC mask
buffer size validation
- Update copyright year for citron
The changes improve memory safety by adding explicit validation checks and
fixing pointer arithmetic in the virtual memory implementation.

Adds missing <memory> header include in common_types.h. This header is
needed for std::unique_ptr and other smart pointer types that may be used
by code including this header.

This commit makes two main changes:
1. Adds support for GetTpcMasks2 (ioctl 0x13) in nvhost_ctrl_gpu:
- Implements new GetTpcMasks2 method to handle TPC mask queries
- Adds IoctlGetTpcMasks structure to store mask parameters
- Returns conservative single TPC configuration for compatibility
2. Enhances memory mapping validation in HostMemory:
- Adds verification check after memory mapping operations
- Improves error handling for direct mapped address enabling
- Adds logging for mapping and direct address failures
Additional changes:
- Updates copyright headers to include citron Emulator Project
- Improves error handling and validation in several paths
- Adds debug logging for TPC mask operations
This improves GPU virtualization support and memory mapping reliability.

Removes usage of std::wstring_convert and std::codecvt_utf8_utf16 which are
deprecated since C++17. Implements direct UTF conversions for:
- UTF16ToUTF8: Manual conversion with proper surrogate pair handling
- UTF8ToUTF16: Direct conversion supporting full Unicode range
- UTF8ToUTF32: New implementation with proper code point extraction
The new implementations are more robust and handle edge cases better while
avoiding deprecated functionality. Windows-specific code paths remain unchanged
using the existing UTF16W conversions.
This change improves maintainability and removes compiler warnings about
deprecated features while maintaining full Unicode support.

Add proper error handling and recovery mechanisms for memory mapping
operations instead of using assertions.

Updates all GitHub repository URLs to point to the new self-hosted Git instance
at git.citron-emu.org. This includes:
- Links in the About dialog UI and translations
- Android app string resources
- Documentation/wiki links
- Source code comments
The website URL (citron-emu.org) and support links remain unchanged.

- In commit b3facaa6bb30cdc39f2b7d632fef1e3bfeee7785, the copyright header was
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.

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
|
|
- 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

|
- Update copyright headers to include Citron Homebrew Project
- Add 2025 to copyright years
|
|
- Replaced all references to the old project name with Citron.
- Added Citron copyright information alongside existing notices in all files.
