Memory Read/Write Tracking using Region Handles (#1272) * 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

GPU - Improve Memory Allocation (#1722) * Implement TreeMap from scratch. Begin implementation of MemoryBlockManager * Implement GetFreePosition using MemoryBlocks * Implementation of Memory Management using a Tree. Still some issues to work around, but promising thus far. * Resolved invalid mapping issue. Performance appears promising. * Add tick metrics * Use the logger instead * Use debug loggin instead of info. * Remove unnecessary code. Add descriptions of added functions. * Improve memory allocation even further. As well as improve speed of position fetching. * Add TreeDictionary to Ryujinx Commons Removed Unnecessary Usigns * Add a Performance Profiler + Improve ReserveFixed * Begin transition to allocation in nvdrv * Create singleton nvmemallocator * Moved Allocation into Nv Related Files As requested by gdkchan, any allocation of memory has been moved into the driver files. Mapping remains in the GPU MemoryManager. * Remove unnecessary usings * Add missing descriptions * Correct descriptions * Fix formatting. * Remove unnecessary whitespace * Formatting / Convention Updates * Changes / Fixes Made syntax and convention changes as requested by gdkchan. Fixed an issue where IsRegionUsed would return the wrong boolean. Fixed an issue where GetFreePosition was asked for an address instead of a size. * Undo commenting of Assert in shader cache * Update Ryujinx.Common/Collections/TreeDictionary.cs Co-authored-by: gdkchan <gab.dark.100@gmail.com> * Resolved many suggestions * Implement Improved TreeDictionary Based off of Pseudo code and custom implementations. * Rename _set to _dictionary * Remove unused code * Remove unused code. * Remove unnecessary MapLow function. * Resolve data-structure based issues * Make adjustments to memory management. Deactive de-allocation for now, it causes more harm than good. * Minor refactorings + Re-implement deallocation Also cleaned up unnecessary code. * Add Tests for TreeDictionary * Update data structure to properly balance the tree * Experimental Implementation: 1. Reduce Time to Next Node to O(1) Runtime 2. Reduce While Loop Ct To 2 (In Most Cases) * Address issues w/ Deallocating Memory * Final Build + Fully Implement Dictionary Interface for new Data Structure + Cover All Memory Allocation Edge Cases, particularly w/ Games that De-Allocate a lot. * Minor Corrections Give TreeDictionary its own count (do not depend on inner dictionary) Properly remove adjacent allocations * Add AsList * Fix bug where internal dictionary wasn't being updated w/ new node for overwritten key. * Address comments in review. * Fix issue where block wouldn't break out (Fixes UE4 issues) * Update descriptions * Update descriptions * Reduce Node visibility to protect TreeDictionary Integrity + Remove usage of struct. * Update tests to use new TreeDictionary implementation. * Remove usage of dictionary in TreeDictionary * Refactoring / Renaming * Remove unneeded memoryblock class. * Add space for while * Add space for if * Formatting / descriptions * Clarified some descriptions * Reduce visibility of memory allocator * Edit method names to make more sense as memory blocks are no longer in use. * Make names consistent. * Protect against npe when sucessorof is called against keys that don't exist. (Not in use by memory manager, this is for other prs that might use this data structure) * Possible edge-case resolve * Update Ryujinx.Common/Collections/TreeDictionary.cs Co-authored-by: gdkchan <gab.dark.100@gmail.com> * Update Ryujinx.HLE/HOS/Services/Nv/NvMemoryAllocator.cs Co-authored-by: gdkchan <gab.dark.100@gmail.com> * Reduce # of unnecessary duplicate variables / Reduce visibility of variables only internally used. * Rename count to _count * Update Description of Add method. * Fix copypasta * Address comments * Address comments * Remove whitespace * Address comments, condense variables. * Consolidate vars * Fix whitespace. * Nit * Fix exception msg * Fix arrayIndex check * Fix arrayIndex check + indexer * Remove whitespace from cast Co-authored-by: gdkchan <gab.dark.100@gmail.com>
