swung0x48 122da27249 [Fix] (DirectGLES): overhaul readback/copy/blit driver-state handling with shadow-backed RAII guards - pixel-PACK/UNPACK PBO binding caches resting at 0 (the old bind-then-query 'restore' left the user PBO bound forever, capturing later client-memory readbacks), a PACK pixel-store shadow replacing per-readback glGetIntegerv syncs, a driver FBO-binding shadow behind all scoped binders (per-instance prev slots, nest-safe), scratch-FBO attachment shadows that detach cross-aspect residue exactly when present (depth CopyTex* attachments used to wedge later GetTexImage color reads and vice versa), scissor guards around emulation blits (app scissor clipped depth copies), stale-driver-error drains before single-shot glGetError consumers (fallbacks silently dropped readbacks / GenerateMipmap raised phantom app errors in production builds), ClearBufferiv missing BindCurrentFBO(Draw), cube-face glBindTexture INVALID_ENUM cache poisoning, per-slice GL_PACK_IMAGE_HEIGHT/SKIP_IMAGES semantics on 3D GetTexImage, backend texture ids deleted on wrapper destruction with cache/scratch-FBO scrubs (ids used to leak for the context lifetime and dangling cache pointers could false-skip binds), and context-death/MakeCurrent invalidation for all new shadows; regression tests drive the shadows against a recording mock GLES table 2026-07-21 19:54:54 -04:00
swung0x48 bc2d698b3e [Fix] (DirectGLES): apply the read buffer when one FBO is bound as both draw and read 
- SyncCurrentFBO skips the READ-target pass when the same GL FBO is bound as
  both draw and read (the common GL_FRAMEBUFFER case), but the read buffer
  (glReadBuffer) is only applied inside SyncToBackend's READ path — so the skip
  silently dropped every glReadBuffer change, leaving the backend read buffer
  stuck at COLOR_ATTACHMENT0.
- Extract the read-buffer application into BackendFramebufferObject::
  SyncReadBufferToBackend and invoke it from the skip branch (target == Read)
  as well as from SyncToBackend, so reads always target the right attachment.
- Bind the backend FBO as READ inside the helper before glReadBuffer, since the
  skip path only bound it as DRAW.
- Fixes KHR-GL3x.draw_buffers.draw_buffers_1 (reading COLOR_ATTACHMENT1 while
  the FBO stays GL_FRAMEBUFFER-bound returned attachment 0's value); the render
  was already correct, only the readback resolved the wrong attachment.

swung0x48 3049c4b82b [Fix] (ShaderTranspiler): stop blanking block comments in the source handed to glslang 
- BlankBlockComments replaced comment chars with spaces but preserved interior newlines, so a block comment spanning a newline inside a #define truncated the macro body (VALUE became empty)
- glslang has a conformant preprocessor and collapses a block comment to one space across newlines, so the delivered source now keeps comments intact and lets glslang handle them
- Fixes KHR-GL3x.shaders.preprocessor multiline_comment_define / redefine_object_multiline_comment / function_redefinition_3 (6 cases, both devices)
- FilterUnsupportedGpuShaderInt64 relied on the blanking to skip commented-out #extension lines; it now masks comments locally (MaskCommentsAndQuotedText) like the sibling passes, collecting edits and applying them back-to-front
- conditional_inclusion.basic_2 (defined() via macro expansion) stays failing by design: glslang rejects it as UB and working around it would mean re-running preprocessing MobileGL defers to glslang

swung0x48 2b3850b76b [Fix] (DirectGLES): upload RGB565/RGB5_A1 shadow data as packed 16-bit types 
- The 8-bit unorm shadow was uploaded as GL_UNSIGNED_BYTE, leaving the 8->5/6-bit requantization to the driver
- That rounding direction is implementation-defined: Adreno rounds to nearest (lossless round trip), Mali floors
- On Mali mid-range texels drifted one 5-bit step down, failing all 20 KHR-GL33.pixelstoragemodes.teximage3d rgb565/rgb5a1 cases (eps 1/32); layers with exact values (0.125/0.25/1.0-ish) passed, matching the observed 0,1,7-valid pattern
- PreparePackedNormUpload repacks shadow rows to GL_UNSIGNED_SHORT_5_6_5 / 5_5_5_1 with round-to-nearest, which exactly recovers the original 5/6-bit values (the shadow expansion is injective), so the driver stores them verbatim
- Idempotent across each region's level loop (glType is shared); RGBA4 exempt since its 8-bit expansion (v*17) is exact under either rounding
- Wired at all four SyncMipmapsToBackend upload regions (append-mipmaps, immutable TexSubImage, mutable full, dirty-level update)

swung0x48 2a0ae743a0 [Fix] (DirectGLES): glFinish before the glGetTexImage temp-FBO readback 
- Mali (tile-based) does not resolve a texture's render into memory when it is read back through a different (temp) FBO than the one it was rendered with
- The cross-FBO glReadPixels raced the deferred tile resolve and returned pre-render clear contents
- Distinct render targets read back byte-identical, so KHR-GLxx.glsl_noperspective failed on Mali-G715 (all four programs read as the clear colour)
- glGetTexImage is already a CPU/GPU sync point so the extra drain is negligible; Adreno resolves eagerly and was unaffected

swung0x48 6839219c10 [Fix] (GLImpl): report GL_NO_ERROR from glGetGraphicsResetStatus 
- The generic export stub returned (GLenum)1; dEQP reads any non-zero status as a lost device
- It is polled after every case (gl3cTestPackages.cpp:121) and sets QP_TEST_RESULT_DEVICE_LOST
- Under the default --deqp-terminate-on-device-lost=enable that tears the whole CTS run down
- MobileGL tracks no GPU resets, so GL_NO_ERROR ("no reset detected") is the honest, spec-correct answer
- Routed through GLImpl::GetGraphicsResetStatus like every other entry point, no inline body in Definitions.cpp
 2026-07-21 02:40:15 -04:00
swung0x48 52ddb440ca [Feat] (SelfTest/DriverPost): add a noperspective correctness check to the GLES POST - render a strong-perspective quad and read the centre texel to verify the varying interpolates screen-linear (not perspective-correct), carried through the native GL_NV_shader_noperspective_interpolation path when present or MobileGL's exact gl_Position.w/gl_FragCoord.w emulation when absent. PASS = native and correct; WARN = emulated and correct (the fallback path shipping packs hit on such devices); FAIL = interpolation wrong/perspective-correct, or the program will not build. The ESSL header matches the device version because noperspective is rejected at #version 300 es on some drivers even with the extension enabled 2026-07-21 02:09:17 -04:00
swung0x48 79feeffd25 [Feat] (ShaderTranspiler, DirectGLES): emulate noperspective on GLES devices lacking GL_NV_shader_noperspective_interpolation - EmulateNoPerspectivePass pre-multiplies each NoPerspective output by gl_Position.w in the vertex stage and recovers each input via gl_FragCoord.w in the fragment stage (exact screen-linear L = P(a*w)*gl_FragCoord.w, handling whole-variable and component/access-chain reads, scalar and vector varyings), forces highp on emulated varyings, and strips what it cannot emulate; replaces the smooth-strip fallback so no NV extension is ever required. Restricts the vertex pre-multiply to the entry function so a non-inlined helper cannot double-scale 2026-07-20 23:48:48 -04:00
swung0x48 202037b5a3 [Fix] (DirectVulkan): shrink the blended depth-write quirk to MIN/MAX extremum blends only - a fixture-wide trace sweep showed the additive ONE+ONE arm never fires on the 26.3 OIT chain (its accumulation passes disable depth writes themselves) and only hit unrelated additive glow content; also fail reflection toward the gl_FragDepth exemption and zero phantom default-FBO blend slots so stale indexed state cannot trigger the strip 2026-07-20 23:39:28 -04:00
swung0x48 bce9c48c8e [Feat] (ShaderTranspiler, DirectGLES): support noperspective conformantly instead of stripping it - let the qualifier reach glslang as the core SPIR-V NoPerspective decoration (native on DirectVulkan; SPIRV-Cross emits ESSL noperspective + GL_NV_shader_noperspective_interpolation on DirectGLES), and for GLES devices lacking that extension add StripNoPerspectivePass to drop the decoration and fall back to smooth; the old naked substring erase discarded the interpolation shader packs need and mangled identifiers containing the word 2026-07-20 22:59:43 -04:00
swung0x48 b6a7807a3a [Fix] (MG_Util/ShaderTranspiler): reject malformed #version directives instead of legalizing them - an unrecognized version number (329/331), a bad profile keyword, a float or trailing token used to be rewritten to "#version 330 core" (or rescued to 460 by the retry); now InspectShaderLanguage marks such directives invalid so NormalizeVersionDirective and RetargetLegacyVersionDirectiveTo460 leave them for glslang to reject, while every valid version still normalizes as before 2026-07-20 22:03:36 -04:00
swung0x48 48ba622387 [Fix] (MG_Util/ShaderTranspiler): keep #line directives instead of deleting them, dropping only the GLSL-illegal quoted filename and the ones that precede #version, so __LINE__ and compiler diagnostics follow the application's own numbering 2026-07-20 21:06:38 -04:00
swung0x48 05260d1262 [Fix] (MG_Util/ShaderTranspiler): blank block comments lexically instead of erasing them - a '//*** banner ***' line opened a comment the old scanner never closed, so it deleted the rest of the shader, and a commented-out builtin definition renamed every genuine call to a name nothing defines 2026-07-20 21:06:37 -04:00
swung0x48 6eb5ff51c5 [Fix] (MG_Impl/GLImpl): reject the RGTC internal formats on 3D texture targets - RGTC compresses 4x4 blocks of a 2D image and has no 3D form, and the check must run on the raw enum because RGTC now resolves to plain R8/RG8 storage 2026-07-20 21:05:57 -04:00
swung0x48 e526f8e8ac [Fix] (MG_Util/Converters): resolve the GL_COMPRESSED_* internal formats to the uncompressed storage that backs them instead of rejecting them as unknown - GL prescribes this base-format fallback for the six generic formats, and RGTC stores uncompressed because ES exposes no compressor 2026-07-20 21:05:57 -04:00
swung0x48 e724e88eec [Fix] (MG_State, MG_Impl/GLImpl): allocating a mipmap level no longer truncates the chain above it - AllocateLevel now only grows and the callers that genuinely redefine the whole level set (glTexStorage*, mip regeneration, multisample storage, level-0 respecification) drop the tail explicitly 2026-07-20 21:02:54 -04:00
swung0x48 3b175fb88a [Fix] (MG_Impl/GLImpl): a multisample sample count above the format's maximum is INVALID_OPERATION, not INVALID_VALUE - matching both the spec and the native Adreno driver 2026-07-20 21:02:53 -04:00
swung0x48 b5a4e7075a [Fix] (MG_Impl/GLImpl): record a GL error from the unimplemented compressed texture entry points instead of throwing - a C++ exception unwinding through the C GL ABI hard-crashes any caller, and glGetCompressedTexImage reported success while writing nothing 2026-07-20 21:02:53 -04:00
swung0x48 520c2b6750 [Fix] (MG_Backend/DirectGLES): sync GL_TEXTURE_SWIZZLE_* on multisample targets - the early return meant to skip the sampler-only parameters dropped every swizzle write, which the frontend already treats as legal on those targets 2026-07-20 21:02:52 -04:00
swung0x48 57cc652b1d [Fix] (MG_Impl/GLImpl): glIsTransformFeedback reports GL_FALSE instead of claiming every name it is handed is a live transform feedback object 2026-07-20 21:02:52 -04:00
swung0x48 65ea54da9e [Refactor] (ShaderTranspiler, DirectVulkan): replace the hand-rolled SPIR-V word walkers with a DecoratePositionInvariantPass and SPIRV-Reflect-based InstanceIndex detection 2026-07-20 08:35:00 -04:00
swung0x48 c81dd04f08 [Test] (CI, trace_replay): force the blended depth-write quirk on the Linux DirectVulkan OIT retrace lane and tighten that case's SSIM threshold to 0.995 2026-07-20 07:39:25 -04:00
swung0x48 c158bfa584 [Fix] (DirectVulkan): narrow the blended depth-write quirk to order-independent accumulation blends, exempting sorted-transparency, gl_FragDepth writers and fully masked attachments 2026-07-20 07:39:25 -04:00
swung0x48 f9f455144c [Refactor] (MG_Config, DirectVulkan): route the blended depth-write quirk through the FeaturesTable as MOBILEGL_MAGMA_DISABLE_BLENDED_DEPTH_WRITE instead of an ad-hoc getenv 2026-07-20 04:37:23 -04:00
swung0x48 64e4840de2 [Fix] (DirectVulkan): fall back to immutable images when the mutable probe fails, gate robustBufferAccess behind MOBILEGL_DISABLE_ROBUST_BUFFER_ACCESS, decode R32/RG32/R16-class readback formats, and warn when shaderStorageImage*WithoutFormat is unavailable 2026-07-20 02:36:26 -04:00
swung0x48 bf7b5755cc [Refactor] (ShaderTranspiler, MG_Backend, MG_Util): gate the subgroup prefix-scan rewrite behind a generic device-quirk registry with GPU vendor detection and MOBILEGL_QUIRK_SUBGROUP_PREFIX_SCAN override, warn on template mismatch, and block ARB/NV subgroup spellings 2026-07-20 02:36:26 -04:00
swung0x48 293f64b3c2 [Fix] (MG_Impl, DirectGLES): correct ARB_clear_texture error codes, reject cube maps in CopyTextureSubImage2D, advertise the extension on Espryt, and pin the error contracts with tests 2026-07-20 02:36:25 -04:00
swung0x48 f0cc07c937 [Perf] (DirectVulkan): bound vertex-stream conversion by the draw's real fetch range, reuse cached prefixes, pin cached source buffers, and stop repacking client arrays for pointer alignment 2026-07-20 02:36:25 -04:00
swung0x48 4658536652 [Perf] (DirectVulkan): keep the render pass alive for steady-state storage-image draws and skip storage-image collection for programs without them 2026-07-20 02:36:24 -04:00
swung0x48 04b4627c65 [Fix] (DirectVulkan): pass depth/stencil formats through sampled-view resolution so D24S8/D32FS8 samplers stop dropping draws, and memoize per-binding view-format resolution 2026-07-20 02:36:24 -04:00
swung0x48 68e13705c8 [Fix] (MG_Backend/DirectVulkan, ShaderTranspiler, MG_Test, TraceReplay): make iterationRP retrace pass on 64-lane Vulkan devices with subgroup-width emulation and format-aware readback 2026-07-20 02:36:23 -04:00
swung0x48 e5388c0e7e [Fix] (MG_Backend, MG_Impl, ShaderTranspiler, MG_Test): support iterationRP custom images and storage format reinterpretation 2026-07-20 02:35:30 -04:00

swung0x48 626c7f26fd [Test] (CMake, CI): enable top-level testing and label tests (unit/benchmark/integration) so ctest runs from the build root 2026-07-18 11:37:56 -04:00

swung0x48 594916850f [Fix] (MG_State, MG_Backend/DirectVulkan): bump the texture bind generation when a context default texture crosses the undefined<->defined boundary so cached sampled sets re-resolve, and collect the fallback texture into the sampled set so its first use transitions outside the render pass 2026-07-17 22:33:31 -04:00
swung0x48 c718d6bad8 [Fix] (MG_Test/Backend/DirectVulkan): link the whole MobileGL_s archive on MSVC so dllimport-declared gl*/egl* references resolve against the in-library entry points 2026-07-17 21:32:17 -04:00
swung0x48 abfda60ff1 [Perf] (MG_Backend/DirectGLES): check the unbind cache before activating the texture unit so the bind-0 sweep stops issuing redundant glActiveTexture per draw 2026-07-17 21:32:16 -04:00
swung0x48 92cced9bcc [Fix] (MG_State, MG_Impl, MG_Test): enforce strict GL 3.3 core rules only on contexts that explicitly request a core profile - texture deleted-name reservation keep and VAO-0 draws relax otherwise or under MOBILEGL_RELAXED_SEMANTICS, and GL_CONTEXT_PROFILE_MASK reports the requested profile 2026-07-17 21:32:16 -04:00
swung0x48 1929a7c546 [Fix] (MG_State, MG_Backend/DirectGLES): preserve legacy texture reuse and clear default backend bindings - keep generated-but-unbound names alive for Minecraft 1.7.10 atlas uploads, synchronize bind-0 to native GLES without 1D/2D alias churn, and cover both paths with BGRA sub-image and binding-cache regressions 2026-07-17 21:32:15 -04:00
swung0x48 df7f5a369d [Fix] (MG_Backend/DirectVulkan): render passes had zero subpass dependencies and same-layout transitions emit no barrier, so tilers could race tile loads against prior passes' stores (flickering artifacts in multi-pass chains like MC 26.3 OIT); add conservative external dependencies both ways 2026-07-17 21:03:52 -04:00
swung0x48 0de9861da4 [Fix] (MG_Backend/DirectVulkan): render-pass cache grew unbounded; age entries per present and evict after 1024 unused frames 2026-07-17 20:03:54 -04:00
swung0x48 6b223e4d23 [Fix] (MG_Backend/DirectVulkan): blendEnable was baked into pipelines without checking VK_FORMAT_FEATURE_COLOR_ATTACHMENT_BLEND_BIT; disable blending on formats that lack it 2026-07-17 20:03:53 -04:00
swung0x48 48568cdb89 [Fix] (MG_Backend/DirectVulkan): deferred glClear/glClearBuffer ignored color/depth/stencil write masks; gate the queued planes like the scissored path 2026-07-17 20:03:53 -04:00
swung0x48 8d83dedc0f [Fix] (MG_Backend/DirectVulkan): pending deferred clears outlived blit/copy writes into the same texture and later stomped them (OIT's cloud_depth copy was erased by its own earlier queued clear); materialize destination pending clears before blit/copy writes 2026-07-17 19:24:55 -04:00
swung0x48 a25d8ee0e7 [Fix] (MG_Backend/DirectGLES): GLES clamps glClearColor to [0,1], zeroing the -FLT_MAX MAX-blend identity; route out-of-range color clears through glClearBufferfv 2026-07-17 11:45:55 -04:00
swung0x48 c30bd0fabb [Fix] (MG_Backend/DirectGLES, MG_Impl/GLImpl): draw/read-buffer state could land on the wrong FBO (glDrawBuffer's static-array latch; SyncToBackend emitting glDrawBuffers/glReadBuffer for the non-bound target; no resync on bound-FBO attachment/drawbuffer edits) leaving MC 26.3's OIT color clears as no-ops; apply per bound target and track the FBO object version 2026-07-17 11:45:54 -04:00
swung0x48 c9fbf79d6a [Fix] (MG_Backend/DirectGLES): blend equations were never synced to the driver (OIT's GL_MAX ran as ADD); diff and emit glBlendEquationSeparate(i) alongside the factor sync 2026-07-17 11:45:53 -04:00
swung0x48 f39e8738da Merge origin/dev (readback overhaul c6d22e6e) into default-texture-objects - true per-target default texture objects supersede the readback branch texture-0 silent no-ops: removed the null-slot early-outs in TexImage1D/2D/3D(Multisample) and TexBuffer plus the DefaultTextureOperationsAreSilentNoOps test so name-0 operations actually (re)specify the default objects; deduped the shared state-reset fixes, keeping upstream std::clamp for GL_MAX_UNIFORM_BUFFER_BINDINGS, the Int-typed ActiveTexture combined-units range check, renderbuffer name-0 unbind, and vertex-attrib-0 current-value writes with the attrib-0 round-trip test 2026-07-16 23:50:47 -04:00

swung0x48 981f10e4da [Fix] (MG_Impl/GLImpl): unblock the non-texture sections of GL CTS per-case state reset - clamp advertised GL_MAX_UNIFORM_BUFFER_BINDINGS to the state layer indexed-binding capacity (glBindBufferBase rejected indices past it), let glBindRenderbuffer(0) unbind without recording INVALID_OPERATION (name 0 must never reach the name-table lookup), and allow writes to generic vertex attribute 0 current value (core GL has no attribute-0 restriction; gluStateReset writes vertexAttrib4f(0,...) after every case) - with these plus the default-texture work, multi-case glcts batches complete in one process instead of aborting after the first case 2026-07-16 23:36:58 -04:00
swung0x48 076cd0d19d [Feat] (MG_State, MG_Impl/GLImpl): per-target default texture objects (name 0) - binding 0 binds a real per-context default object (the initial binding of every unit/target slot, rebound on delete of a bound texture), so glTexImage*/glTexParameter*/glGetTex* on it work like any texture while glIsTexture(0)/Gen/Delete keep excluding it and TexStorage* rejects it per spec; backends skip image-less defaults as cheaply as the old null slots (DirectGLES per-draw sync/bind loops, DirectVulkan sampler-fallback resolve); also accept the full advertised GL_MAX_COMBINED_TEXTURE_IMAGE_UNITS range in glActiveTexture, allow zero-layer TexImage3DMultisample, and let glTexBuffer(buffer=0) detach - the texture section of GL CTS per-case state reset (gluStateReset) now runs clean 2026-07-16 23:36:43 -04:00
swung0x48 5cd82f2002 Merge origin/dev (efd7b473) into readback overhaul - unify DirectGLES 2D-array target support under MapToBackendTextureTarget, keep canonical UNorm8 shadows for RGBA4/RGB565 (supersedes packed-word transfer types; GL_RGB565 aliases RGB5), keep upstream GLSL 330 normalization, anisotropy params, error-count semantics and VK clear/scissor fixes 2026-07-16 23:17:37 -04:00
swung0x48 d4922cb0fb [Fix] (MG_Backend, MG_Impl/GLImpl, MG_Util): make anisotropic filtering actually reachable - advertise GL_EXT/ARB_texture_filter_anisotropic only where the host driver or the samplerAnisotropy device feature supports it, answer GL_MAX_TEXTURE_MAX_ANISOTROPY_EXT from the backend limit, and honor the sampler state on DirectVulkan (feature enable, limit clamp, LINEAR-only gate, resolved value in the sampler cache key) 2026-07-16 22:59:11 -04:00
swung0x48 870d882fef [Fix] (MG_Backend/DirectGLES, MG_Impl/GLImpl, MG_Util): GL CTS packed_pixels + texture_swizzle readback overhaul - canonical shadow layouts for legacy sized/unsized/packed internal formats (RGB5->RGB565, RGB10/12->RGB16, RGBA2->RGBA4, RGB10_A2(UI)/RGB9_E5/R11F_G11F_B10F packed-word shadows with per-texel encode/decode incl. 5_9_9_9_REV and 10F_11F_11F_REV client types), GL_UNSIGNED_INT_10_10_10_2 pixel type mapping, conversion-first GetTexImage with CPU-shadow fallback for non-attachable formats and stale-temp-FBO detach, narrow implementation read pairs + SNORM read candidates + 2_10_10_10_REV wide-read decode with RGBA expansion, PACK image/skip and SWAP_BYTES honored on the CPU repack (never in ES), state-reset conformance (default-texture TexParameter/TexImage/TexBuffer no-ops, renderbuffer 0 unbind, vertex attrib 0 current value, ActiveTexture up to combined units, UBO binding count clamp), FramebufferTexture3D/TextureLayer slice attachments via glFramebufferTextureLayer, capability-driven FBO UNSUPPORTED for non-renderable colors, ReadPixels integer-ness mismatch error, single-value texture swizzle validation, and DirectGLES 1D/1D-array/2D-array texture emulation (2D/2D-array backend targets matching SPIRV-Cross ES 1D-as-2D shaders) 2026-07-16 22:41:54 -04:00
swung0x48 e2f873c95c [Fix] (MG_Util/ShaderTranspiler): retry a legacy shader at 460 when it fails to parse as normalized 330 core, so sources using 420-era syntax without the matching #extension line keep compiling as they did on real drivers 2026-07-16 22:33:30 -04:00

swung0x48 25323bfb8e [Fix] (MG_Backend/DirectGLES, MG_Impl/GLImpl): sync GL_TEXTURE_2D_ARRAY textures to the ES backend - the target was skipped as unsupported so array textures never uploaded or bound (every KHR-GL33.pixelstoragemodes.teximage3d case failed); also keep array layer counts constant across mip levels in TexStorage3D and generated-mip storage allocation (only true 3D textures halve depth) 2026-07-16 19:44:20 -04:00
