From e88718a32db1d5315e98d1e2c83b9dd512e3251f Mon Sep 17 00:00:00 2001 From: LoVisual AI Date: Sat, 10 Oct 2026 13:08:27 +0000 Subject: [PATCH] =?UTF-8?q?feat(mod):=20Stage=203=20(partial)=20=E2=80=94?= =?UTF-8?q?=20RenderBackendOps=20interface=20+=203=20GL=20mixins?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Per mod/docs/optimize-layer-design.md Stage 3 (partial). This commit ships the simplest GL mixins and the strategy interface that splits GL/Vulkan backends. SkinAtlas/AnimFreeze/HudCache/FrameFence deferred to a later pass because they're more complex (vertex-format / glCopyImageSubData / RenderPipeline+RenderPass). RenderBackendOps interface (features/.../optimize/gl/RenderBackendOps.java): - Backend-agnostic surface for lazy clear, TBO cache, RenderTypes cache. - current() resolves the active backend — returns GlRenderBackendOps on GL, null on Vulkan (so all WrapOperations fall through to the vanilla call). - Stage 4 will add a VulkanRenderBackendOps no-op implementation. GlRenderBackendOps (features/.../optimize/gl/GlRenderBackendOps.java): - Concrete GL implementation. Three caches ported from ZakoOpt: * Lazy clear (from zako.opt.mixin.gl.GlCommandEncoderClearMixin). * TBO cache (from zako.opt.gl.TexBufferCache + the TexBufferMixin). * RenderTypes cache (from zako.opt.mixin.gl.RenderTypesMixin). - All three gated on OptimizeToggles.microOpts() (the Stage 1 'micro_opts' toggle wired in Optimize.java). - Includes test helpers (resetForTesting, boundTboTextureForTesting, cachedRenderTypeCountForTesting). Three new mixins (mixins/optimize/): - RenderTypesMixin: WrapOperation on RenderTypes.entityTranslucent's BiFunction.apply — cache by Identifier when flag=true (the common case). Drops the per-call Objects.hash(Pair) hit. - GlCommandEncoderClearMixin: WrapOperation on GlCommandEncoder's clearColorAndDepthTextures → GlStateManager._glBindFramebuffer — skip the bind-framebuffer-0 because the next render pass binds its own target anyway and GlStateManager's cache already skips redundant binds. - GlCommandEncoderTexBufferMixin: WrapOperation on GlCommandEncoder's trySetup → glBindTexture (track bound) and glTexBuffer (skip re-attach when the same (format, buffer) pair is already attached). Re-attaching makes the driver revalidate the texture (clouds: ~2% of a frame). lovisual.mixins.json: - Register all three mixins + OptimizeDebugHudMixin in the 'client' array, alphabetically under optimize.* (before accessors.*). OptimizeDebugHudMixin (mixins/optimize/OptimizeDebugHudMixin.java): - F3 overlay for the Optimize layer — Stage 2 of the design doc. - Adds three blocks of lines to F3 (after the existing LoVisual Engine block): * 'LoVisual Optimize' — toggles summary + budget mode + scale + frame time. * 'frame:' — EMA-averaged per-section timings (entities/particles/HUD/effects/text). * 'props:' — when any -Dlovisual.opt.* is set, list which ones. - Mirrors the existing hud.DebugHudMixin pattern (ModifyArg on extractLines). Tests (JUnit 5): 11 new tests in GlRenderBackendOpsTest — pure-logic pieces of RenderBackendOps + Identifier equality/hash. Total suite: 849 tests, 0 failures. checkFolderLimit: OK (0 folders >4). --- .../misc/optimize/gl/GlRenderBackendOps.java | 140 +++++++++++++ .../misc/optimize/gl/RenderBackendOps.java | 118 +++++++++++ .../optimize/GlCommandEncoderClearMixin.java | 40 ++++ .../GlCommandEncoderTexBufferMixin.java | 57 ++++++ .../optimize/OptimizeDebugHudMixin.java | 101 ++++++++++ .../mixins/optimize/RenderTypesMixin.java | 62 ++++++ mod/src/main/resources/lovisual.mixins.json | 4 + .../optimize/gl/GlRenderBackendOpsTest.java | 185 ++++++++++++++++++ 8 files changed, 707 insertions(+) create mode 100644 mod/src/main/java/dev/loki/lovisual/features/module/modules/misc/optimize/gl/GlRenderBackendOps.java create mode 100644 mod/src/main/java/dev/loki/lovisual/features/module/modules/misc/optimize/gl/RenderBackendOps.java create mode 100644 mod/src/main/java/dev/loki/lovisual/mixins/optimize/GlCommandEncoderClearMixin.java create mode 100644 mod/src/main/java/dev/loki/lovisual/mixins/optimize/GlCommandEncoderTexBufferMixin.java create mode 100644 mod/src/main/java/dev/loki/lovisual/mixins/optimize/OptimizeDebugHudMixin.java create mode 100644 mod/src/main/java/dev/loki/lovisual/mixins/optimize/RenderTypesMixin.java create mode 100644 mod/src/test/java/dev/loki/lovisual/features/module/modules/misc/optimize/gl/GlRenderBackendOpsTest.java diff --git a/mod/src/main/java/dev/loki/lovisual/features/module/modules/misc/optimize/gl/GlRenderBackendOps.java b/mod/src/main/java/dev/loki/lovisual/features/module/modules/misc/optimize/gl/GlRenderBackendOps.java new file mode 100644 index 00000000..63f558ff --- /dev/null +++ b/mod/src/main/java/dev/loki/lovisual/features/module/modules/misc/optimize/gl/GlRenderBackendOps.java @@ -0,0 +1,140 @@ +package dev.loki.lovisual.features.module.modules.misc.optimize.gl; + +import dev.loki.lovisual.render.engine.optimize.OptimizeToggles; +import it.unimi.dsi.fastutil.ints.Int2LongOpenHashMap; + +import java.util.Map; +import java.util.concurrent.ConcurrentHashMap; + +/** + * GL backend implementation of {@link RenderBackendOps}. + * + *
