* video_core: replace Fortune's Weave's DLSS with AMD FSR 3.1Duck91231 hours1-2/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fire Emblem: Fortune's Weave's DLSS network can't run here, and the temporal stand-in is only an approximation of it. FSR 3.1 takes the same inputs DLSS does: the jittered colour, motion vectors, the jitter and the depth, which the game's first DLSS pass reads through cbuf0+0x298 (Z32, reversed, the colour's size). Kepler compute keeps it next to the motion vectors. Fsr3Upscaler ports the host side of the SDK's ffx_fsr3upscaler.cpp: the eight passes (prepare inputs, luma and shading-change pyramids, shading change, reactivity, luma instability, accumulate, RCAS), the internal images and the constants, recorded through the scheduler with the shaders from externals/FidelityFX-SDK. It takes HDR colour, render-size motion vectors and reversed depth, computes its own exposure, and uses the no-wave SPD variants on devices without compute quad operations. The SDK's GLSL uses separate textures and samplers, so DescriptorBankInfo gains sampled image and sampler counts (default 0). FSR's RCAS follows the RCAS Sharpness slider. The result goes to FSR's own RGBA16F image and is drawn into the game's output, which keeps its format. TextureCacheRuntime::TemporalUpscale runs FSR 3.1 first. Without the depth, at mismatched scales, on a device lacking FSR's formats or features, or if its pipelines fail to build, the stand-in runs instead, and the bilinear blit stays last. EDEN_NX2_DLSS_REPLACEMENT=standin forces the stand-in. A gap of more than 250 ms between evaluations restarts the history. The BlitColor overload that takes a raw image view transitions its source to SHADER_READ_ONLY_OPTIMAL but described it as GENERAL in the descriptor (a validation error); it now describes the layout it uses.

* nx2: read GPU-written command lists from copies instead of drainingTakoroka36 hours1-0/+14
| | | | | | | | | | | | | | | | | | | | | | The trees fix (#52) drains the split and flushes for every command list on a GPU-written page: in a Mario Kart World race ~13,500 lists and ~400 GPU round trips a second, during which the back has nothing to do. The replay ran at ~40 fps instead of ~45. The front now marks the pages those lists are on. The buffer cache notes writes to them; after a compute dispatch or DMA copy that writes one it copies the page into host memory and submits. The front waits for the back only up to the last compute or copy work it sent (not everything queued), then reads the copy once the GPU is done with it. Pages the GPU wrote once, long before, and the CPU now writes lists to have no copy: their first list drains and flushes the whole page, which is then read from guest memory until GPU work writes it again. CPU writes and inline uploads reach guest memory, so they keep such a page synced but make a copy stale. A page a draw writes always drains. Mario Kart World time-trial replay, Radeon 780M: ~40 -> ~45 fps, trees drawn, no list drains left.
* video_core: temporal upscale stand-in for Fortune's Weave's DLSSDuck9122 days1-0/+11
| | | | | | | | | | | | | | | | | The one-frame blit left 3D edges aliased and shaking: the game jitters its camera every frame for DLSS to accumulate. Fire Emblem: Fortune's Weave's first DLSS pass (also rejected) has the motion vectors (cbuf0+0x290, R16G16) and the frame's jitter (+0x1b0/+0x1b4, in input pixels). Kepler compute keeps them, and the stand-in for the last network pass now draws temporal_upscale.frag: input samples placed where the jitter put them and weighted by distance, blended with the previous result reprojected along the motion vectors (Catmull-Rom) and clipped to the 3x3 neighbourhood in YCoCg. The history is copied from the result right after drawing it, so post-processing the game later applies to its output does not feed back. EDEN_NX2_TEMPORAL_UPSCALE=0 restores the blit.

Solutioin was to share locks between both. P.S.: THIS IS INTENDED TO FIX RANDOM CRASHES IN UE, OBJECTIVELY REPRODUCIBLE IN ENDER MAGNOLIA IN ANDROID.

* video_core: Reimplement the buffer cacheReinUsesLisp2021-02-131-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Reimplement the buffer cache using cached bindings and page level granularity for modification tracking. This also drops the usage of shared pointers and virtual functions from the cache. - Bindings are cached, allowing to skip work when the game changes few bits between draws. - OpenGL Assembly shaders no longer copy when a region has been modified from the GPU to emulate constant buffers, instead GL_EXT_memory_object is used to alias sub-buffers within the same allocation. - OpenGL Assembly shaders stream constant buffer data using glProgramBufferParametersIuivNV, from NV_parameter_buffer_object. In theory this should save one hash table resolve inside the driver compared to glBufferSubData. - A new OpenGL stream buffer is implemented based on fences for drivers that are not Nvidia's proprietary, due to their low performance on partial glBufferSubData calls synchronized with 3D rendering (that some games use a lot). - Most optimizations are shared between APIs now, allowing Vulkan to cache more bindings than before, skipping unnecesarry work. This commit adds the necessary infrastructure to use Vulkan object from OpenGL. Overall, it improves performance and fixes some bugs present on the old cache. There are still some edge cases hit by some games that harm performance on some vendors, this are planned to be fixed in later commits.
* video_core: Rewrite the texture cacheReinUsesLisp2020-12-301-2/+10
| | | | | | | | | | | | | | The current texture cache has several points that hurt maintainability and performance. It's easy to break unrelated parts of the cache when doing minor changes. The cache can easily forget valuable information about the cached textures by CPU writes or simply by its normal usage.The current texture cache has several points that hurt maintainability and performance.

* video_core: Remove all Core::System references in rendererReinUsesLisp2020-09-061-5/+2
| | | | | | | | | Now that the GPU is initialized when video backends are initialized, it's no longer needed to query components once the game is running: it can be done when yuzu is booting. This allows us to pass components between constructors and in the process remove all Core::System references in the video backend.
* {maxwell_3d,buffer_cache}: Implement memory barriers using 3D registersReinUsesLisp2020-04-281-0/+3
| | | | | | | | | | | | | Drop MemoryBarrier from the buffer cache and use Maxwell3D's register WaitForIdle. To implement this on OpenGL we just call glMemoryBarrier with the necessary bits. Vulkan lacks this synchronization primitive, so we set an event and immediately wait for it. This is not a pretty solution, but it's what Vulkan can do without submitting the current command buffer to the queue (which ends up being more expensive on the CPU).
