* common: add arm64 native clockGravatar Liam2023-10-081-1/+7
|
* wall_clock: Increase precision requirementsGravatar Morph2023-07-271-2/+2
| | | | We are providing a conversion to nanoseconds in NativeClock, which is more precise than the GPU tick.
* (wall, native)_clock: Add GetGPUTickGravatar Morph2023-06-071-2/+6
| | | | Allows us to directly calculate the GPU tick without double conversion to and from the host clock tick.
* (wall, native)_clock: Rework NativeClockGravatar Morph2023-06-071-45/+28
|
* core_timing: Use higher precision sleeps on WindowsGravatar Morph2023-03-051-0/+5
| | | | | | 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.
* wall_clock: Make use of SteadyClockGravatar Morph2023-03-051-23/+11
|
* common/x64: Use TSC clock rate from CPUID when availableGravatar Marshall Mohror2022-07-061-1/+1
| | | | 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.
* general: Convert source file copyright comments over to SPDXGravatar Morph2022-04-231-3/+2
| | | | | 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.
* common: Reduce unused includesGravatar ameerj2022-03-191-2/+0

* common: wall_clock: Check precision against the emulated CPU and CNTFRQGravatar Morph2022-01-301-6/+10
| | | | 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.
* common: wall_clock: Utilize constants for ms, us, and ns ratiosGravatar Morph2022-01-301-2/+2
|
* wall_clock: use standard wall clock if rtsc frequency is too lowGravatar german772022-01-271-1/+3
|
* common: wall_clock: Fix integer overflow with StandardWallClock.Gravatar bunnei2021-02-191-7/+8
| | | | | - 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.
* common: wall_clock: Optimize GetClockCycles/GetCPUCycles to use a single MUL ↵Gravatar bunnei2021-02-151-8/+9
| | | | instruction.
* audio_core: Make shadowing and unused parameters errorsGravatar Lioncash2020-12-031-2/+2
| | | | Moves the audio code closer to enabling warnings as errors in general.
* common: Enable warnings as errorsGravatar Lioncash2020-11-021-1/+1
| | | | Cleans up common so that we can enable warnings as errors.
* common/wall_clock: Add virtual destructorsGravatar ReinUsesLisp2020-09-301-1/+1
| | | | | | | | 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.
* Common/Kernel: Corrections and small bug fixing.Gravatar Fernando Sahmkow2020-06-271-6/+1

* HostTiming: Pause the hardware clock on pause.Gravatar Fernando Sahmkow2020-06-271-0/+4

* Core/HostTiming: Allow events to be advanced manually.Gravatar Fernando Sahmkow2020-06-181-4/+5
