* x64: Deduplicate RDTSC usageMorph2023-06-084-19/+80

* x64: Simplify RDTSC on non-MSVC compilersMorph2023-03-272-16/+10
| | | | Co-Authored-By: liamwhite <liamwhite@users.noreply.github.com>
* x64: Add MicroSleepMorph2023-03-272-0/+82
| | | | | | | MicroSleep allows the processor to pause for a "short" amount of time (in the microsecond range). This is useful for spin-waiting that does not require nanosecond precision. This uses the new TPAUSE instruction introduced on Intel's newest processors as part of the waitpkg instructions. For CPUs that do not support waitpkg instructions, this is equivalent to yield().

* x64: cpu_detect: Add detection of waitpkg instructionsMorph2023-03-272-0/+2
| | | | waitpkg introduces 3 instructions, UMONITOR, UMWAIT and TPAUSE.
* native_clock: Wait for 10 seconds instead of 30Morph2023-03-081-3/+3
| | | | It was experimentally determined to be sufficient.
* native_clock: Use RealTimeClock instead of SteadyClockMorph2023-03-081-4/+4
| | | | We want to synchronize RDTSC to real time.
* native_clock: Re-adjust the RDTSC frequencyMorph2023-03-082-5/+34
| | | | | 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.

* chore: make yuzu REUSE compliantAndrea Pappacoda2022-07-272-6/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | [REUSE] is a specification that aims at making file copyright information consistent, so that it can be both human and machine readable. It basically requires that all files have a header containing copyright and licensing information. When this isn't possible, like when dealing with binary assets, generated files or embedded third-party dependencies, it is permitted to insert copyright information in the `.reuse/dep5` file. Oh, and it also requires that all the licenses used in the project are present in the `LICENSES` folder, that's why the diff is so huge. This can be done automatically with `reuse download --all`. The `reuse` tool also contains a handy subcommand that analyzes the project and tells whether or not the project is (still) compliant, `reuse lint`. Following REUSE has a few advantages over the current approach: - Copyright information is easy to access for users / downstream - Files like `dist/license.md` do not need to exist anymore, as `.reuse/dep5` is used instead - `reuse lint` makes it easy to ensure that copyright information of files like binary assets / images is always accurate and up to date To add copyright information of files that didn't have it I looked up who committed what and when, for each file. As yuzu contributors do not have to sign a CLA or similar I couldn't assume that copyright ownership was of the "yuzu Emulator Project", so I used the name and/or email of the commit author instead.

* common/x64: Use TSC clock rate from CPUID when availableMarshall Mohror2022-07-062-0/+18
| | | | 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.

* cpu_detect: Add additional x86 flags and telemetryWunkolo2022-03-112-11/+40
| | | | | | | | | | | Adds detection of additional CPU flags to cpu_detect and additions to telemetry output. This is not exhaustive but guided by features that [dynarmic utilizes](https://github.com/merryhime/dynarmic/blob/bcfe377aaa5138af740e90af5be7a7dff7b62a52/src/dynarmic/backend/x64/host_feature.h#L12-L33) as well as features that are currently utilized but not reported to telemetry(invariant_tsc). This is intended to guide future optimizations. AVX512 in particular is broken up into its individual subsets and some other processor features such as [sha](https://en.wikipedia.org/wiki/Intel_SHA_extensions) and [gfni](https://en.wikipedia.org/wiki/AVX-512#GFNI) are added to have some forward-facing data-points. What used to be a single `CPU_Extension_x64_AVX512` telemetry field is also broken up into individual `CPU_Extension_x64_AVX512{F,VL,CD,...}` fields.

|
* cpu_detect: Compact capability fieldsWunkolo2022-03-091-20/+21
| | | | | As this structure gets more explicit, bools can be bitfields and small enums can use smaller types for their span of values.

|
* common/xbyak_api: Make BuildRegSet() constexprLioncash2022-01-261-8/+8
| | | | | This allows us to eliminate any static constructors that would have been emitted due to the function not being constexpr.
* common/cpu_detect: Remove CPU family and modelMorph2021-12-141-12/+0
| | | | We currently do not make use of these fields, remove them for now.
* native_clock: Wait for less time in EstimateRDTSCFrequencyMorph2021-12-041-18/+18
| | | | | 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.
* general: Replace high_resolution_clock with steady_clockMorph2021-12-021-3/+3
| | | | On some OSes, high_resolution_clock is an alias to system_clock and is not monotonic in nature. Replace this with steady_clock.

| | | | Cleans up common so that we can enable warnings as errors.
* common/wall_clock: Add virtual destructorsReinUsesLisp2020-09-301-1/+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.
* externals: Update Xbyak to 5.96Lioncash2020-08-301-16/+16
| | | | | | | | | I made a request on the Xbyak issue tracker to allow some constructors to be constexpr in order to avoid static constructors from needing to execute for some of our register constants. This request was implemented, so this updates Xbyak so that we can make use of it.

| | | | | | | Xbyak is currently entirely unused. Rather than carting it along, remove it and get rid of a dependency. If it's ever needed in the future, then it can be re-added (and likely be more up to date at that point in time).
