* [core, gpu, threads] Multithreading refactor (#4254)CamilleLaVey2026-08-081-33/+505
| | | | | | This insufferable work tries to cover some holes on previous threading implementation from yuzu's team, starting with Windows and Linux reordering of priorities (NICE), reworks previous Android's threading and cpu affinity with adpf, adjust emulated clocks/gpu for better "accuracy" with their work, bumps android minSDK for all flavors, legacy will now work with AP 29 to cover A10 - A12, standard will reach A13 as base and finally the optimized build will come with API 35, mostly targeted on devices with A15 support and newer, NDK and AGP wasn't upgraded yet. The performance cost efficiency have been improved based on device power configuration; preventing overheating if certain devices tended to fall into NICE0 (not allocated threads priority, all task ran with higher priority, 11 tasks running within the limited 2 - 7 threads available on the most common configuration 1x3x4 or 1x4x3).

* [core/core_timing] better MWAITX and WAITPKG delays (#3984)lizzie2026-05-301-2/+104
| | | | | | | | | | | | | This implements MWAITX and WAITPKG extensions (umonitor, mwait) for CPUs that support them. Reduces wait times and bypasses the timing stuff from the OS that is slow (windows notably). generally it should answer within 0.2 to 0.5 microsecs (since most requests wait for that long). Also does a general rework of static ctors and stuff Signed-off-by: lizzie <lizzie@eden-emu.dev> Reviewed-on: https://git.eden-emu.dev/eden-emu/eden/pulls/3984 Reviewed-by: MaranBr <maranbr@eden-emu.dev> Reviewed-by: crueter <crueter@eden-emu.dev>
* [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?!?!?!

* Fix thread naming on Linux, which limits names to 15 bytes.comex2020-08-051-0/+12
| | | | | | | | | | | | | | | - In `SetCurrentThreadName`, when on Linux, truncate to 15 bytes, as (at least on glibc) `pthread_set_name_np` will otherwise return `ERANGE` and do nothing. - Also, add logging in case `pthread_set_name_np` returns an error anyway. This is Linux-specific, as the Apple and BSD versions of `pthread_set_name_np return `void`. - Change the name for CPU threads in multi-core mode from "yuzu:CoreCPUThread_N" (19 bytes) to "yuzu:CPUCore_N" (14 bytes) so it fits into the Linux limit. Some other thread names are also cut off, but I didn't bother addressing them as you can guess them from the truncated versions. For a CPU thread, truncation means you can't see which core it is!

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * IOFile: Make the move constructor and move assignment operator noexcept Certain parts of the standard library try to determine whether or not a transfer operation should either be a copy or a move. The prevalent notion of move constructors/assignment operators is that they should not throw, they simply move an already existing resource somewhere else. This is typically done with 'std::move_if_noexcept'. Like the name says, if a type's move constructor is noexcept, then the functions retrieves an r-value reference (for move semantics), or an l-value (for copy semantics) if it is not noexcept. As IOFile deletes the copy constructor and copy assignment operators, using IOFile with certain parts of the standard library can fail in unexcepted ways (especially when used with various container implementations). This prevents that. * fix various instances of -1 being assigned to unsigned types * do not assign in conditional statements * File/IOFile: Check _tfopen_s properly * common/file_util.cpp: address review comments Co-authored-by: Lioncash <mathew1800@gmail.com> Co-authored-by: Shawn Hoffman <godisgovernment@gmail.com> Co-authored-by: Sepalani <sepalani@hotmail.fr>
* common/thread: Remove unused functionsLioncash2019-03-291-37/+0
| | | | | | | | | | Many of these functions are carried over from Dolphin (where they aren't used anymore). Given these have no use (and we really shouldn't be screwing around with OS-specific thread scheduler handling from the emulator, these can be removed. The function for setting the thread name is left, however, since it can have debugging utility usages.

| | | | This is inconsistent with our coding style.
* common/thread: Remove SleepCurrentThread()Lioncash2018-11-211-11/+0
| | | | | | | This is also unused and superceded by standard functionality. The standard library provides std::this_thread::sleep_for(), which provides a much more flexible interface, as different time units can be used with it.
* common/thread: Remove unused CurrentThreadId()Lioncash2018-11-211-10/+0
| | | | | | This is an old function that's no longer necessary. C++11 introduced proper threading support to the language and a thread ID can be retrieved via std::this_thread::get_id() if it's ever needed.
