* Add short duration texture cache
This texture cache takes textures that lose their last pool reference and keeps them alive until the next frame, or until an incompatible overlap removes it. This is done since under certain circumstances, a texture's reference can be wiped from a pool despite it still being in use - though typically the reference will return when rendering the next frame.
While this may slightly increase texture memory usage when quickly going through a bunch of temporary textures, it's still bounded due to the overlap removal rule.
This greatly increases performance in Hyrule Warriors: Age of Calamity. It may positively affect some UE4 games which dip framerate severely under certain circumstances.
* Small optimization
* Don't forget this.
* Add short cache dictionary
* Address feedback
* Address some feedback
* Make all structs readonly when applicable. It should reduce amount of needless defensive copies
* Make structs with trivial boilerplate equality code record structs
* Remove unnecessary readonly modifiers from TextureCreateInfo
* Make BitMap structs readonly too
* Initial Implementation
About as fast as nvidia GL multithreading, can be improved with faster command queuing.
* Struct based command list
Speeds up a bit. Still a lot of time lost to resource copy.
* Do shader init while the render thread is active.
* Introduce circular span pool V1
Ideally should be able to use structs instead of references for storing these spans on commands. Will try that next.
* Refactor SpanRef some more
Use a struct to represent SpanRef, rather than a reference.
* Flush buffers on background thread
* Use a span for UpdateRenderScale.
Much faster than copying the array.
* Calculate command size using reflection
* WIP parallel shaders
* Some minor optimisation
* Only 2 max refs per command now.
The command with 3 refs is gone. 😌
* Don't cast on the GPU side
* Remove redundant casts, force sync on window present
* Fix Shader Cache
* Fix host shader save.
* Fixup to work with new renderer stuff
* Make command Run static, use array of delegates as lookup
Profile says this takes less time than the previous way.
* Bring up to date
* Add settings toggle. Fix Muiltithreading Off mode.
* Fix warning.
* Release tracking lock for flushes
* Fix Conditional Render fast path with threaded gal
* Make handle iteration safe when releasing the lock
This is mostly temporary.
* Attempt to set backend threading on driver
Only really works on nvidia before launching a game.
* Fix race condition with BufferModifiedRangeList, exceptions in tracking actions
* Update buffer set commands
* Some cleanup
* Only use stutter workaround when using opengl renderer non-threaded
* Add host-conditional reservation of counter events
There has always been the possibility that conditional rendering could use a query object just as it is disposed by the counter queue. This change makes it so that when the host decides to use host conditional rendering, the query object is reserved so that it cannot be deleted. Counter events can optionally start reserved, as the threaded implementation can reserve them before the backend creates them, and there would otherwise be a short amount of time where the counter queue could dispose the event before a call to reserve it could be made.
* Address Feedback
* Make counter flush tracked again.
Hopefully does not cause any issues this time.
* Wait for FlushTo on the main queue thread.
Currently assumes only one thread will want to FlushTo (in this case, the GPU thread)
* Add SDL2 headless integration
* Add HLE macro commands.

* Make GPU memory manager a member of GPU channel
* Move physical memory instance to the memory manager, and the caches to the physical memory
* PR feedback
* Ground work for separate GPU channels
* Rename TextureManager to TextureCache
* Decouple texture bindings management from the texture cache
* Rename BufferManager to BufferCache
* Decouple buffer bindings management from the buffer cache
* More comments and proper disposal
* PR feedback
* Force host state update on channel switch
* Typo
* PR feedback
* Missing using
* Support for resources on non-contiguous GPU memory regions
* Implement MultiRange physical addresses, only used with a single range for now
* Actually use non-contiguous ranges
* GetPhysicalRegions fixes
* Documentation and remove Address property from TextureInfo
* Finish implementing GetWritableRegion
* Fix typo
* Interrupt GPU command processing when a frame's fence is reached.
* Accumulate times rather than %s
* Accurate timer for vsync
Spin wait for the last .667ms of a frame. Avoids issues caused by signalling 16ms vsync. (periodic stutters in smo)
* Use event wait for better timing.
* Fix lazy wait
Windows doesn't seem to want to do 1ms consistently, so force a spin if we're less than 2ms.
* A bit more efficiency on frame waits.
Should now wait the remainder 0.6667 instead of 1.6667 sometimes (odd waits above 1ms are reliable, unlike 1ms waits)
* Better swap interval 0 solution
737 fps without breaking a sweat. Downside: Vsync can no longer be disabled on games that use the event heavily (link's awakening - which is ok since it breaks anyways)
* Fix comment.
* Address Comments.
* Add swizzle matching rules.
Improves rules which try to match incompatible formats as perfect, such as D32 float -> R32 float.
Remove Format.HasOneComponent, since this information is now available via the FormatInfo struct.
* Fix this rule.
* Update component counts for depth formats.
* Initial implementation of Render Target Scaling
Works with most games I have. No GUI option right now, it is hardcoded.
Missing handling for texelFetch operation.
* Realtime Configuration, refactoring.
* texelFetch scaling on fragment shader (WIP)
* Improve Shader-Side changes.
* Fix potential crash when no color/depth bound
* Workaround random uses of textures in compute.
This was blacklisting textures in a few games despite causing no bugs. Will eventually add full support so this doesn't break anything.
* Fix scales oscillating when changing between non-native scales.
* Scaled textures on compute, cleanup, lazier uniform update.
* Cleanup.
* Fix stupidity
* Address Thog Feedback.
* Cover most of GDK's feedback (two comments remain)
* Fix bad rename
* Move IsDepthStencil to FormatExtensions, add docs.
* Fix default config, square texture detection.
* Three final fixes:
- Nearest copy when texture is integer format.
- Texture2D -> Texture3D copy correctly blacklists the texture before trying an unscaled copy (caused driver error)
- Discount small textures.
* Remove scale threshold.
Not needed right now - we'll see if we run into problems.
* All CPU modification blacklists scale.
* Fix comment.
* Implement GPU syncpoints
This adds support for GPU syncpoints on the GPU backend & nvservices.
Everything that was implemented here is based on my researches,
hardware testing of the GM20B and reversing of nvservices (8.1.0).
Thanks to @fincs for the informations about some behaviours of the pusher
and for the initial informations about syncpoints.
* syncpoint: address gdkchan's comments
* Add some missing logic to handle SubmitGpfifo correctly
* Handle the NV event API correctly
* evnt => hostEvent
* Finish addressing gdkchan's comments
* nvservices: write the output buffer even when an error is returned
* dma pusher: Implemnet prefetch barrier
lso fix when the commands should be prefetch.
* Partially fix prefetch barrier
