2025-01-14Revert incorrect copyright attribution for non-contributed filesZephyron
- 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.
2024-12-31chore: update project references and add Citron copyrightZephyron
- Replaced all references to the old project name with Citron. - Added Citron copyright information alongside existing notices in all files.

2023-07-27wall_clock: Increase precision requirementsMorph
We are providing a conversion to nanoseconds in NativeClock, which is more precise than the GPU tick.
2023-06-07(wall, native)_clock: Add GetGPUTickMorph
Allows us to directly calculate the GPU tick without double conversion to and from the host clock tick.

2023-03-05core_timing: Use higher precision sleeps on WindowsMorph
The precision of sleep_for and wait_for is limited to 1-1.5ms on Windows. Using SleepForOneTick() allows us to sleep for exactly one interval of the current timer resolution. This allows us to take advantage of systems that have a timer resolution of 0.5ms to reduce CPU overhead in the event loop.

2022-07-06common/x64: Use TSC clock rate from CPUID when availableMarshall Mohror
The current method used to estimate the TSC is fairly accurate - within a few kHz - but the exact value can be extracted from CPUID if available.
2022-04-23general: Convert source file copyright comments over to SPDXMorph
This formats all copyright comments according to SPDX formatting guidelines. Additionally, this resolves the remaining GPLv2 only licensed files by relicensing them to GPLv2.0-or-later.

2022-01-30common: wall_clock: Check precision against the emulated CPU and CNTFRQMorph
In addition to requiring nanosecond precision, using the native clock requires that the hardware TSC has a precision greater than the emulated CPU and its clock counter.

2021-02-19common: wall_clock: Fix integer overflow with StandardWallClock.bunnei
- Previous optimized impl. resulted in an integer overflow, so revert. - This is our slow/fallback path that should never be really be used, so the optimization in unimportant.

2020-12-03audio_core: Make shadowing and unused parameters errorsLioncash
Moves the audio code closer to enabling warnings as errors in general.
2020-11-02common: Enable warnings as errorsLioncash
Cleans up common so that we can enable warnings as errors.
2020-09-30common/wall_clock: Add virtual destructorsReinUsesLisp
From -fsanitize=address, this code wasn't calling the proper destructor. Adding virtual destructors for each inherited class and the base class fixes this bug. While we are at it, mark the functions as final.
