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.

2023-06-07(wall, native)_clock: Add GetGPUTickMorph
Allows us to directly calculate the GPU tick without double conversion to and from the host clock tick.

2023-03-07native_clock: Wait for 10 seconds instead of 30Morph
It was experimentally determined to be sufficient.
2023-03-07native_clock: Use RealTimeClock instead of SteadyClockMorph
We want to synchronize RDTSC to real time.
2023-03-07native_clock: Re-adjust the RDTSC frequencyMorph
The RDTSC frequency reported by CPUID is not accurate to its true frequency. We will spawn a separate thread to calculate the true RDTSC frequency after a measurement period of 30 seconds has elapsed.

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.

2021-12-03native_clock: Wait for less time in EstimateRDTSCFrequencyMorph
In my testing, waiting for 200ms provided the same level of precision as the previous implementation when estimating the RDTSC frequency. This significantly improves the yuzu executable launch times since we reduced the wait time from 3 seconds to 200 milliseconds.
2021-12-02general: Replace high_resolution_clock with steady_clockMorph
On some OSes, high_resolution_clock is an alias to system_clock and is not monotonic in nature. Replace this with steady_clock.
