- Move the message handler into its debugger class part,
- Move all message types into one file and collapse 3 of the ones with no data into a generic, stateless message with a single property being its type,
- Add an Fpscr helper property on IExecutionContext along with a comment about what Fpscr is (similar to the other registers in there)
- Moved the Rcmd helpers (such as GetRegisters, GetMinidump, etc) into a dedicated Debugger class part,
- Fixed the double-collection (ToArray being called twice) in GetThreadUids & GetThread in KProcess
This PR changes the core count to be defined in the device instead of
being a const value.
This is mostly a change for future features I want to implement and
should not impact any functionality.
The console will now log the range of cores requested from the
application, and for now, if the requested range is not 0 to 2 (the 3
cores used for application emulation), it will give an error message
which tells the user to contact me on discord. I'm doing this because
I'm interested in finding applications/games that don't use 3 cores and
the error will be removed in the future once I've gotten enough data.
* Kernel: Wake cores from idle directly rather than through a host thread
Right now when a core enters an idle state, leaving that idle state requires us to first signal the core's idle thread, which then signals the correct thread that we want to run on the core. This means that in a lot of cases, we're paying double for a thread to be woken from an idle state.
This PR moves this process to happen on the thread that is waking others out of idle, instead of an idle thread that needs to be woken first.
For compatibility the process has been kept as similar as possible - the process for IdleThreadLoop has been migrated to TryLeaveIdle, and is gated by a condition variable that lets it run only once at a time for each core. A core is only considered for wake from idle if idle is both active and has been signalled - the signal is consumed and the active state is cleared when the core leaves idle.
Dummy threads (just the idle thread at the moment) have been changed to have no host thread, as the work is now done by threads entering idle and signalling out of it.
This could put a bit of extra work on threads that would have triggered `_idleInterruptEvent` before, but I'd expect less work than signalling all those reset events and the OS overhead that follows. Worst case is that other threads performing these signals at the same time will have to wait for each other, but it's still going to be a very short amount of time.
Improvements are best seen in games with heavy (or very misguided) multithreading, such as Pokemon: Legends Arceus. Improvements are expected in Scarlet/Violet and TOTK, but are harder to measure.
Testing on Linux/MacOS still to be done, definitely need to test more games as this affects all of them (obviously) and any issues might be rare to encounter.

* Didn't I already do this
* Cleanup
* perf: use ByteMemoryPool
* feat: KPageTableBase/KPageTable new methods to read and write `ReadOnlySequence<byte>`
* new: add IWritableBlock.Write(ulong, ReadOnlySequence<byte>) with default impl
* perf: use GetReadOnlySequence() instead of GetSpan()
* perf: make `Parcel` IDisposable, use `ByteMemoryPool` for internal allocation, and make Parcel consumers dispose of it

* feat: add nanosleep for linux and macos
* Add Windows 0.5ms sleep
- Imprecise waits for longer waits with clock alignment
- 1/4 the spin time on vsync timer
* Remove old experiment
* Fix event leak
* Tweaking for MacOS
* Linux tweaks, nanosleep vsync improvement
* Fix overbias
* Cleanup
* Fix realignment
* Add some docs and some cleanup
NanosleepPool needs more, Nanosleep has some benchmark code that needs removed.
* Rename "Microsleep" to "PreciseSleep"
Might have been confused with "microseconds", which no measurement is performed in.
* Remove nanosleep measurement
* Remove unused debug logging
* Nanosleep Pool Documentation
* More cleanup
* Whitespace
* Formatting
* Address Feedback
* Allow SleepUntilTimePoint to take EventWaitHandle
* Remove `_chrono` stopwatch in SurfaceFlinger
* Move spinwaiting logic to PreciseSleepHelper
Technically, these achieve different things, but having them here makes them easier to reuse or tune.
* Implement reprotect method on virtual memory manager (currently stubbed)
* Force all exclusive memory accesses to be ordered on AppleHv
* Format whitespace
* Fix test build
* Fix comment copy/paste
* Fix wrong bit for isLoad
* Update src/Ryujinx.Cpu/AppleHv/HvMemoryManager.cs
