* Return mapped buffer pointer directly for flush, WriteableRegion for textures
A few changes here to generally improve performance, even for platforms not using the persistent buffer flush.
- Texture and buffer flush now return a ReadOnlySpan<byte>. It's guaranteed that this span is pinned in memory, but it will be overwritten on the next flush from that thread, so it is expected that the data is used before calling again.
- As a result, persistent mappings no longer copy to a new array - rather the persistent map is returned directly as a Span<>. A similar host array is used for the glGet flushes instead of allocating new arrays each time.
- Texture flushes now do their layout conversion into a WriteableRegion when the texture is not MultiRange, which allows the flush to happen directly into guest memory rather than into a temporary span, then copied over. This avoids another copy when doing layout conversion.
Overall, this saves 1 data copy for buffer flush, 1 copy for linear textures with matching source/target stride, and 2 copies for block textures or linear textures with mismatching strides.
* Fix tests
* Fix array pointer for Mesa/Intel path
* Address some feedback
* Update method for getting array pointer.
* Initial implementation of buffer flush (VERY WIP)
* Host shaders need to be rebuilt for the SSBO write flag.
* New approach with reserved regions and gl sync
* Fix a ton of buffer issues.
* Remove unused buffer unmapped behaviour
* Revert "Remove unused buffer unmapped behaviour"
This reverts commit f1700e52fb8760180ac5e0987a07d409d1e70ece.
* Delete modified ranges on unmap
Fixes potential crashes in Super Smash Bros, where a previously modified range could lie on either side of an unmap.
* Cache some more delegates.
* Dispose Sync on Close
* Also create host sync for GPFifo syncpoint increment.
* Copy buffer optimization, add docs
* Fix race condition with OpenGL Sync
* Enable read tracking on CommandBuffer, insert syncpoint on WaitForIdle
* Performance: Only flush individual pages of SSBO at a time
This avoids flushing large amounts of data when only a small amount is actually used.
* Signal Modified rather than flushing after clear
* Fix some docs and code style.
* Introduce a new test for tracking memory protection.
Sucessfully demonstrates that the bug causing write protection to be cleared by a read action has been fixed. (these tests fail on master)
* Address Comments
* Add host sync for SetReference
This ensures that any indirect draws will correctly flush any related buffer data written before them. Fixes some flashing and misplaced world geometry in MH rise.
* Make PageAlign static
* Re-enable read tracking, for reads.
Here come Salieri, my implementation of a disk shader cache!
"I'm sure you know why I named it that."
"It doesn't really mean anything."
This implementation collects shaders at runtime and cache them to be later compiled when starting a game.
* WIP Range Tracking
- Texture invalidation seems to have large problems
- Buffer/Pool invalidation may have problems
- Mirror memory tracking puts an additional `add` in compiled code, we likely just want to make HLE access slower if this is the final solution.
- Native project is in the messiest possible location.
- [HACK] JIT memory access always uses native "fast" path
- [HACK] Trying some things with texture invalidation and views.
It works :)
Still a few hacks, messy things, slow things
More work in progress stuff (also move to memory project)
Quite a bit faster now.
- Unmapping GPU VA and CPU VA will now correctly update write tracking regions, and invalidate textures for the former.
- The Virtual range list is now non-overlapping like the physical one.
- Fixed some bugs where regions could leak.
- Introduced a weird bug that I still need to track down (consistent invalid buffer in MK8 ribbon road)
Move some stuff.
I think we'll eventually just put the dll and so for this in a nuget package.
Fix rebase.
[WIP] MultiRegionHandle variable size ranges
- Avoid reprotecting regions that change often (needs some tweaking)
- There's still a bug in buffers, somehow.
- Might want different api for minimum granularity
Fix rebase issue
Commit everything needed for software only tracking.
Remove native components.
Remove more native stuff.
Cleanup
Use a separate window for the background context, update opentk. (fixes linux)
Some experimental changes
Should get things working up to scratch - still need to try some things with flush/modification and res scale.
Include address with the region action.
Initial work to make range tracking work
Still a ton of bugs
Fix some issues with the new stuff.
* Fix texture flush instability
There's still some weird behaviour, but it's much improved without this. (textures with cpu modified data were flushing over it)
* Find the destination texture for Buffer->Texture full copy
Greatly improves performance for nvdec videos (with range tracking)
* Further improve texture tracking
* Disable Memory Tracking for view parents
This is a temporary approach to better match behaviour on master (where invalidations would be soaked up by views, rather than trigger twice)
The assumption is that when views are created to a texture, they will cover all of its data anyways. Of course, this can easily be improved in future.
* Introduce some tracking tests.
WIP
* Complete base tests.
* Add more tests for multiregion, fix existing test.
* Cleanup Part 1
* Remove unnecessary code from memory tracking
* Fix some inconsistencies with 3D texture rule.
* Add dispose tests.
* Use a background thread for the background context.
Rather than setting and unsetting a context as current, doing the work on a dedicated thread with signals seems to be a bit faster.
Also nerf the multithreading test a bit.
* Copy to texture with matching alignment
This extends the copy to work for some videos with unusual size, such as tutorial videos in SMO. It will only occur if the destination texture already exists at XCount size.
* Track reads for buffer copies. Synchronize new buffers before copying overlaps.
* Remove old texture flushing mechanisms.
Range tracking all the way, baby.
* Wake the background thread when disposing.
Avoids a deadlock when games are closed.
* Address Feedback 1
* Separate TextureCopy instance for background thread
Also `BackgroundContextWorker.InBackground` for a more sensible idenfifier for if we're in a background thread.
* Add missing XML docs.
* Address Feedback
* Maybe I should start drinking coffee.
* Some more feedback.
* Remove flush warning, Refocus window after making background context
* Initial implementation. Still pending better valid-overlap handling,
disposed pool, compressed format flush fix.
* Very messy backend resource cache.
* Oops
* Dispose -> Release
* Improve Release/Dispose.
* More rule refinement.
* View compatibility levels as an enum - you can always know if a view is only copy compatible.
* General cleanup.
Use locking on the resource cache, as it is likely to be used by other threads in future.
* Rename resource cache to resource pool.
* Address some of the smaller nits.
* Fix regression with MK8 lens flare
Texture flushes done the old way should trigger memory tracking.
* Use TextureCreateInfo as a key.
It now implements IEquatable and generates a hashcode based on width/height.
* Fix size change for compressed+non-compressed view combos.
Before, this could set either the compressed or non compressed texture with a size with the wrong size, depending on which texture had its size changed. This caused exceptions when flushing the texture.
Now it correctly takes the block size into account, assuming that these textures are only related because a pixel in the non-compressed texture represents a block in the compressed one.
* Implement JD's suggestion for HashCode Combine

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.

* 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.
* Implementation of query queue and host conditional rendering
* Resolve some comments.
* Use overloads instead of passing object.
* Wake the consumer threads when incrementing syncpoints.
Also, do a busy loop when awaiting the counter for a blocking flush, rather than potentially sleeping the thread.
* Ensure there's a command between begin and end query.
