From ca59c3f4998e2d1beb3b0d0214611e3332238557 Mon Sep 17 00:00:00 2001 From: riperiperi Date: Mon, 2 Sep 2024 01:28:16 +0100 Subject: Vulkan: Feedback loop detection and barriers (#7226) * Vulkan: Feedback loop improvements This PR allows the Vulkan backend to detect attachment feedback loops. These are currently used in the following ways: - Partial use of VK_EXT_attachment_feedback_loop_layout - All renderable textures have AttachmentFeedbackLoopBitExt - Compile pipelines with Color/DepthStencil feedback loop flags when present - Support using FragmentBarrier for feedback loops (fixes regressions from https://github.com/Ryujinx/Ryujinx/pull/7012 ) TODO: - AMD GPUs may need layout transitions for it to properly allow textures to be used in feedback loops. - Use dynamic state for feedback loops. The background pipeline will always miss since feedback loop state isn't known on the GPU project. - How is the barrier dependency flag used? (DXVK just ignores it, there's no vulkan validation...) - Improve subpass dependencies to fix validation errors * Mark field readonly * Add feedback loop dynamic state * fix: add MoltenVK resolver workaround fix: add MoltenVK resolver workaround * Formatting * Fix more complaints * RADV dcc workaround * Use dynamic state properly, cleanup. * Use aspects flags in more places --- .../GraphicsDriver/DriverUtilities.cs | 24 ++++++++++++++++++++-- 1 file changed, 22 insertions(+), 2 deletions(-) (limited to 'src/Ryujinx.Common/GraphicsDriver/DriverUtilities.cs') diff --git a/src/Ryujinx.Common/GraphicsDriver/DriverUtilities.cs b/src/Ryujinx.Common/GraphicsDriver/DriverUtilities.cs index 7fe2a4f0..a9163f34 100644 --- a/src/Ryujinx.Common/GraphicsDriver/DriverUtilities.cs +++ b/src/Ryujinx.Common/GraphicsDriver/DriverUtilities.cs @@ -1,13 +1,33 @@ +using Ryujinx.Common.Utilities; using System; namespace Ryujinx.Common.GraphicsDriver { public static class DriverUtilities { + private static void AddMesaFlags(string envVar, string newFlags) + { + string existingFlags = Environment.GetEnvironmentVariable(envVar); + + string flags = existingFlags == null ? newFlags : $"{existingFlags},{newFlags}"; + + OsUtils.SetEnvironmentVariableNoCaching(envVar, flags); + } + + public static void InitDriverConfig(bool oglThreading) + { + if (OperatingSystem.IsLinux()) + { + AddMesaFlags("RADV_DEBUG", "nodcc"); + } + + ToggleOGLThreading(oglThreading); + } + public static void ToggleOGLThreading(bool enabled) { - Environment.SetEnvironmentVariable("mesa_glthread", enabled.ToString().ToLower()); - Environment.SetEnvironmentVariable("__GL_THREADED_OPTIMIZATIONS", enabled ?
