* 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.
* Improve performance when converting texture formats.
Still more work to do.
* Speed up buffer -> texture copies.
No longer copies byte by byte. Fast path when formats are identical.
* Fix a few things, 64 byte block fast copy.
* Spacing cleanup, unrelated change.
* Fix base offset calculation for region copies.
* Fix Linear -> BlockLinear
* Fix some nits. (part 1 of review feedback)
* Use a generic version of the Convert* functions rather than lambdas.
This is some real monkey's paw shit.
* Remove unnecessary span constructor.
* Revert "Use a generic version of the Convert* functions rather than lambdas."
This reverts commit aa43dcfbe8.
* Fix bug with rectangle destination writing, better rectangle calculation for linear textures.
* Viewport swizzle support on NV and clip origin
* Initialize default viewport swizzle state, emulate viewport swizzle on shaders when not supported
* Address PR feedback
* Support separate textures and samplers
* Add missing bindless flag, fix SNORM format on buffer textures
* Add missing separation
* Add comments about the new handles
* 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.
* Implement Constant Color blends and init blend states
* Address gdkchan's comments
Also adds Set methods to GpuState
* Fix descriptions of QueryModified
* Initial conditional rendering support
* Properly reset state
* Support conditional modes and skeleton a counter cache for future host conditional rendering
* Address PR feedback
* 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
* Add a missing syncpoint check in QueryEvent of NvHostSyncPt
* Address Ac_K's comments and fix GetSyncpoint for ChannelResourcePolicy == Channel
* fix SyncptWait & SyncptWaitEx cmds logic
* Address ripinperi's comments
* Address gdkchan's comments
* Move user event management to the control channel
* Fix mm implementation, nvdec works again
* Address ripinperi's comments
* Address gdkchan's comments
* Implement nvhost-ctrl close accurately + make nvservices dispose channels when stopping the emulator
* Fix typo in MultiMediaOperationType
* Implement RasterizeEnable
* Match viewport count to hardware
* Simplify ScissorTest tracking around Blits
* Disable RasterizerDiscard around Blits and track its state
* Read RasterizeEnable reg as bool and add doc
* Only enumarate cached textures that are modified when flushing, rather than all of them.
* Remove locking.
* Add missing clear.
* Remove texture from modified list when data is disposed.
In case the game does not call either flush method at any point.
* Add ReferenceEqualityComparer from jD for the HashSet
* Use correct shader local size instead of a hardcoded size
* Remove unused uniform block
* Update XML doc
* Local memory size has 23 bits on maxwell
* Generate compute QMD struct from nv open doc header
* Remove dummy arrays when shared or local memory is not used, other improvements
Support shared color masks (used by Nouveau and maybe the NVIDIA
driver).
Support draw buffers (also required by OpenGL).
Support viewport transform disable (disabled for now as it breaks some
games).
Fix instanced rendering draw being ignored for multi draw.
Fix IADD and IADD3 immediate shader encodings, that was not matching
some ops.
Implement FFMA32I shader instruction.
Implement IMAD shader instruction.
