swung0x48 bcb0e894ef [Fix, Test] (MG_State, MG_Backend/DirectGLES, MG_Util, MG_IntegrationTest, MG_Test): array layout(binding=N) elements bind consecutively, a read+write image reaches ESSL legally, compute local_size comes from the linked intermediate, and glShaderStorageBlockBinding is baked into the generated source 2026-08-11 23:05:21 -04:00

swung0x48 5a7bd9942d [Fix] (MG_Backend/DirectVulkan): print VkShaderModule as a 64-bit value - the const void* cast is ill-formed on 32-bit ABIs where the handle is a plain uint64_t 2026-08-11 08:19:31 -04:00
swung0x48 21a43bf6a4 [Fix, Test] (MG_Backend/DirectVulkan): re-land the gl_FragCoord default-framebuffer origin fix - the suspected slowdown was a mismeasurement, paired timings are within 1% 2026-08-11 07:54:24 -04:00
swung0x48 5b6dec2d81 [Revert] (MG_Backend/DirectVulkan): back out the gl_FragCoord default-framebuffer origin fix - correct, but it costs DirectVulkan a large order-dependent slowdown that is not yet root-caused 2026-08-11 06:30:30 -04:00
swung0x48 543c29bf86 [Fix, Test] (MG_Backend/DirectVulkan): gl_FragCoord on the default framebuffer reports GL's window origin - the stored row is not the window row once the viewport rect is converted 2026-08-11 05:25:32 -04:00
swung0x48 ef562ee9b5 [Fix, Test] (MG_Backend/DirectGLES): backend framebuffer, renderbuffer and sampler twins release their driver ids - a framebuffer per readback leaked the driver into stale pixels 2026-08-11 03:54:05 -04:00

swung0x48 5c8a9c41d6 [Fix, Test] (MG_Impl, MG_State): GL entry points record errors instead of throwing through the C ABI - CopyTexImage superset rule, TEXTURE_BUFFER level queries, indexed cap toggles 2026-08-11 02:24:41 -04:00
swung0x48 efa0345c36 [Fix] (MG_Backend/DirectVulkan): offscreen surfaces never touch a window system - delete the hidden-Xlib fallback, make surface and device-enumeration failures loud, guard zero devices 2026-08-11 00:58:24 -04:00
swung0x48 ce0f18969c [Fix] (MG_Util): dlopen the versioned libEGL.so.1 first - the unversioned name is a dev-package symlink absent on runtime-only systems, and its silent failure nulled every EGL entry point 2026-08-11 00:58:23 -04:00

swung0x48 9fa32bdad0 [Fix] (DirectVulkan): declare only the used colour attachment span per subpass
- every render pass declared colorAttachmentCount=8 (the full GL draw-buffer
  slot span) with trailing VK_ATTACHMENT_UNUSED references, and Adreno
  configures its per-pixel render-backend/export path from the DECLARED
  count - so every fragment of every pass paid an 8-render-target export
  cost; this was the bulk of the 1.5x per-pixel gap against
  MobileGlues+ANGLE on the same Qualcomm driver (their subpasses declare
  exactly the used span)
- measured on Adreno 650 / MC 26.2 / 1440x3044: total GPU frame time
  11.9 -> 7.5 ms (-37%, now below ANGLE's 7.87 ms), the single-quad
  swapchain blit pass alone 1.26 -> 0.40 ms, steady in-world FPS 82.8 -> 123
  under the standard cooled-start protocol, matching the
  MobileGlues+ANGLE+system-Vulkan benchmark of 123.8
- trailing UNUSED references are popped before the subpass is built (the
  entry's colorAttachmentCount and every pipeline's colour-blend span follow
  it); interior GL_NONE holes keep their slots so fragment-output locations
  still line up
- the pipeline-side fragmentOutputMask check downgrades from assert to a
  debug log: an output at a location past the trimmed span is discarded,
  which is GL's defined behaviour for a draw buffer set to GL_NONE
2026-07-30 02:45:39 -04:00
swung0x48 a4980f2b56 [Fix] (DirectVulkan): skip redundant per-draw dynamic-state commands
- viewport, scissor, blend constants, depth bias, line width and the six
  stencil parameters were re-emitted unconditionally for EVERY draw (~1500
  vkCmdSet* per frame in MC 26.2, where ANGLE emits a handful), costing CPU
  record time and GPU command-processor work for values that almost never
  change between draws
- a recording-scoped shadow now drops any vkCmdSet* whose values match what
  the command buffer already holds; valid because every PipelineFactory
  pipeline declares the same eight dynamic states, so set values persist
  across those binds
- the shadow resets at every command-buffer (re)begin (dynamic state does
  not survive the boundary) and after binding the blit or depth-mipmap
  pipelines, whose narrower dynamic sets make the untouched states undefined
  and whose raw viewport/scissor writes bypass the shadow
2026-07-30 02:45:07 -04:00
swung0x48 8ca20e28ca [Fix] (DirectVulkan): size texture backings by their defined mip level count
- every non-MSAA texture was allocated with a full mip chain regardless of
  how many levels the GL texture actually defines, so MC's 3044x1440 main
  colour and depth render targets each carried 12 levels where ANGLE
  allocates one; a level-0-only texture now gets a single-level backing and
  upgrades to the full chain exactly once when a second level is first
  defined, through the existing preserve-copy recreation path
- saves a third of the memory of every mip-less texture and keeps
  single-level render targets off the multi-mip image layout entirely, which
  also removes the surface the Adreno 650 implicit-LOD overread workaround
  (ForceExplicitLod0SamplePass) exists to defend
- measured perf-neutral on Adreno 650 / MC 26.2 (the driver keeps full UBWC
  on multi-mip render targets), so this is a memory/robustness fix, not a
  speed one
2026-07-30 02:43:32 -04:00
swung0x48 c353a2055f [Feat] (DirectVulkan): pre-pass command stream for reorderable out-of-pass work
- a draw whose sampled texture needs out-of-pass work (deferred clear
  materialization or a sampled-layout transition) used to end the active
  render pass - a full-target store+reload on a tiler - even when the only
  ordering the work needs is 'before this draw'; MC 26.2 clears an overlay
  texture every frame and samples it mid-pass, splitting the main scene pass
  once per frame for nothing
- every frame slot now carries a second primary command buffer, submitted
  strictly AHEAD of the frame command buffer in the same vkQueueSubmit; when
  the open recording has not referenced the image yet (tracked via a
  recording-generation stamp on the texture resource, advanced on every
  frame-command-buffer begin and stamped at every recorded reference:
  attachments at BeginRenderPass/attachment-write, sampled reads per draw,
  layout transitions), the clear/transition is recorded there and the active
  pass stays open - ANGLE's outside-render-pass command stream, restricted
  to the provably reorderable case
- mid-frame flushes and readback submits close and carry the pre stream with
  the frame buffer (it must never be submitted later than the recording it
  was paired with), retiring both under the same submit index; dropped
  recordings (present suspension, swapchain recreation) abandon it
- MaterializePendingClearForTexture's no-active-render-pass assert now
  applies only to the frame command buffer, since the pre stream records
  while a pass is open on the frame buffer by design

swung0x48 421c20984e [Fix] (DirectVulkan): stop loading and carrying dead default-framebuffer content
- EGL swap semantics make the presented colour buffer's content undefined at
  its next acquire (EGL_BUFFER_DESTROYED, the implementation default) and
  every ancillary depth/stencil buffer's content undefined after ANY swap,
  yet the default-FBO render pass reloaded both with LOAD_OP_LOAD every
  frame; SwapchainObject now tracks per-image content validity (defined when
  a pass stores into the attachment, invalidated at present) and the
  render-pass manager turns an undefined attachment's tile load into
  LOAD_OP_DONT_CARE with initialLayout=UNDEFINED, keyed into both hashes so
  the cached LOAD variants cannot be hit by mistake
- the default framebuffer's depth attachment is now attached ON DEMAND: a
  draw with depth test and stencil test both disabled (GL: a disabled test
  neither reads nor writes its buffer), and no pending depth/stencil clear,
  resolves to a depth-less pass flavour, dropping the D24S8 tile load AND
  store outright - MC 26.2 renders its GUI into its own FBO and only ever
  blits colour to the default framebuffer, so its swapchain pass carried a
  full-screen depth round-trip for nothing
- the flavour only escalates: an active depth-full pass absorbs depth-less
  draws unchanged, while a depth-using draw against a depth-less pass
  resolves to an incompatible entry and splits, its depth loading DONT_CARE
  (the content was undefined all along); the depth-less flavour is folded
  into ComputeHash and the per-draw fast-path memo so the two flavours can
  never alias
