From c41fddd25e8ddd3cf0b3cefeaf6595d2e4ede0fa Mon Sep 17 00:00:00 2001 From: gdkchan Date: Sun, 26 May 2024 15:20:10 -0300 Subject: [PATCH] Vulkan: Extend full bindless to cover cases with phi nodes (#6853) * Key textures using set and binding (rather than just binding) * Extend full bindless to cover cases with phi nodes * Log error on bindless access failure * Shader cache version bump * Remove constant buffer match to reduce the chances of full bindless triggering * Re-enable it for constant buffers, paper mario does actually need it * Format whitespace --- .../Shader/DiskCache/DiskCacheHostStorage.cs | 2 +- .../Optimizations/BindlessElimination.cs | 55 +++++++++++++++---- 2 files changed, 46 insertions(+), 11 deletions(-) diff --git a/src/Ryujinx.Graphics.Gpu/Shader/DiskCache/DiskCacheHostStorage.cs b/src/Ryujinx.Graphics.Gpu/Shader/DiskCache/DiskCacheHostStorage.cs index 990c6ba3b1..fbf48f017e 100644 --- a/src/Ryujinx.Graphics.Gpu/Shader/DiskCache/DiskCacheHostStorage.cs +++ b/src/Ryujinx.Graphics.Gpu/Shader/DiskCache/DiskCacheHostStorage.cs @@ -22,7 +22,7 @@ namespace Ryujinx.Graphics.Gpu.Shader.DiskCache private const ushort FileFormatVersionMajor = 1; private const ushort FileFormatVersionMinor = 2; private const uint FileFormatVersionPacked = ((uint)FileFormatVersionMajor << 16) | FileFormatVersionMinor; - private const uint CodeGenVersion = 6870; + private const uint CodeGenVersion = 6852; private const string SharedTocFileName = "shared.toc"; private const string SharedDataFileName = "shared.data"; diff --git a/src/Ryujinx.Graphics.Shader/Translation/Optimizations/BindlessElimination.cs b/src/Ryujinx.Graphics.Shader/Translation/Optimizations/BindlessElimination.cs index 29501b710e..02a83fbe40 100644 --- a/src/Ryujinx.Graphics.Shader/Translation/Optimizations/BindlessElimination.cs +++ b/src/Ryujinx.Graphics.Shader/Translation/Optimizations/BindlessElimination.cs @@ -38,6 +38,12 @@ namespace Ryujinx.Graphics.Shader.Translation.Optimizations // If we can't do bindless elimination, remove the texture operation. // Set any destination variables to zero. + string typeName = texOp.Inst.IsImage() + ?
