* [common] Switch to boost::unordered_flat containers (#4326)crueter2026-08-311-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Replaces all instances of ankerl's unordered map/set with boost's `unordered_flat_*` classes. This uses std::hash since boost::hash is actually a lot slower. Also adds an abstraction layer in `Common` so future changes are quicker and easier. Other implementation details: - ankerl provided hash specializations for tuple and pair, so those were ported here - std::erase_if doesn't work on boost, so just used the ADL'd erase_if This should be about equal or superior performance as unordered_dense for everything except iteration.

* [common/logging] Simplify logging logic and fix issues when logging before ↵lizzie2026-03-121-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | system is created (#3688) - our logging code was bigger than spdlog itself, why???? just keep it simple - fix issues when logging before logging system is even started - removes the "initialized logging twice" issue - removes uneeded indirection in file logging - uses direct formatting instead of jumping hoopla-around the fmt::format() ressult - code duplication and dead code removal as usual I did explore dup2() but I think it's not worth the hassle I did try `fwopen()` but it's better if things are just kept as-is. there is a lot of noise because I removed a bunch of redundant files on logging and just put everything in one file now normally this wouldn't be a good idea, however consider: the complexity of logging; it's less than 500 lines... does it really need a whole subsystem?!?!?!

Ensures compatibility with color formats and adds fallbacks for depth/stencil. • Memory fix misallocation: Adds checks for null/zero-length operations in memory management and improves cleanup to avoid crashes (Related to crash issues due to misallocation, RP5 and 865) • Vulkan Initialization (RAII): this almost rewrites the way vulkan initializes to avoid crashes, using a correct order now (thanks @crueter for the initial fix) •Please check before merging: - Test MSAA workflows (especially color/depth transitions and low memory cases). - Verify memory operations (e.g., unmapping zero-length regions). - Check Vulkan object lifetimes and platform-specific behavior. - Check others plataforms beyond android Why is everything in one PR?

This helps with the buildup of mappings in /proc/YUZU_PID/maps after a longer gaming session, improving stability without having to increase vm.max_map_count to a ridiculous value. The amount of placeholder mappings will no longer outgrow the amount of actual memfd mappings in cases of high memory fragmentation.
