* 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
* Changes to allow explicit management of service threads
* Remove now unused code
* Remove ThreadCounter, its no longer needed
* Allow and use separate server per service, also fix exit issues
* New policy change: PTC version now uses PR number
* Implement block placement
Implement a simple pass which re-orders cold blocks at the end of the
list of blocks in the CFG.
* Set PPTC version
* Use Array.Resize
Address gdkchan's feedback
* Relax block ordering constraints
Before `block.Next` had to follow `block.ListNext`, now it does not.
Instead `CodeGenerator` will now emit the necessary jump instructions
to ensure control flow.
This makes control flow and block order modifications easier. It also
eliminates some simple cases of redundant branches.
* Set PPTC version
* SIMD&FP load/store with scale > 4 should be undefined
* Catch more invalid encodings for FP&SIMD LDR/STR (reg variant)
* Set PTC version to PR number
* Allow launching with custom data directories
Don't load alternate keys when using custom directory
* Address gdkchan's comments
* Misc fixes to log levels
Added more enabled log levels by default
Moved successful config updation to Notice as
1. It's not a warning
2. Warnings could've been disabled by the config load and hence message
would be lost
* Add Compare instruction
* Add BranchIf instruction
* Use test when BranchIf & Compare against 0
* Propagate Compare into BranchIfTrue/False use
- Propagate Compare operations into their BranchIfTrue/False use and
turn these into a BranchIf.
- Clean up Comparison enum.
* Replace BranchIfTrue/False with BranchIf
* Use BranchIf in EmitPtPointerLoad
- Using BranchIf early instead of BranchIfTrue/False improves LCQ and
reduces the amount of work needed by the Optimizer.
EmitPtPointerLoader was a/the big producer of BranchIfTrue/False.
- Fix asserts firing when assembling BitwiseAnd because of type
mismatch in EmitStoreExclusive. This is harmless and should not
cause any diffs.
* Increment PPTC interval version
* Improve IRDumper for BranchIf & Compare
* Use BranchIf in EmitNativeCall
* Clean up
* Do not emit test when immediately preceded by and
* Logger class changes only
Now compile-time checking is possible with the help of Nullable Value
types.
* Misc formatting
* Manual optimizations
PrintGuestLog
PrintGuestStackTrace
Surfaceflinger DequeueBuffer
* Reduce SendVibrationXX log level to Debug
* Add Notice log level
This level is always enabled and used to print system info, etc...
Also, rewrite LogColor to switch expression as colors are static
* Unify unhandled exception event handlers
* Print enabled LogLevels during init
* Re-add App Exit disposes in proper order
nit: switch case spacing
* Revert PrintGuestStackTrace to Info logs due to #1407
PrintGuestStackTrace is now called in some critical error handlers
so revert to old behavior as KThread isn't part of Guest.
* Batch replace Logger statements
* Use movd,movq for i32/64 VectorExtract %x, 0x0
* Increment PPTC interval version
* Use else-if instead
- Address gdkchan's feedback.
- Clean up Debug.Assert calls
* Inline `count` expression into Debug.Assert
Apparently the CoreCLR JIT will not eliminate this. :(
