    Message : List vulkan_core.h as input of generate_vulkan_layers_json.py. Since this was missing, the layer json files didn't get regenerated on vulkan rolls, leading to stale generated json files, which in turn led to incremental builds having different files in the swarming isolate than full builds. To make this type of bug harder to introduce, rewrite generate_vulkan_layers_json.py a bit: - pass in path to vulkan_core.h as an argument - also pass in the input .json / .json.in files as arguments, so that the script re-runs if a .json or .json.in input is added or removed, and in the script verify that the passed-in list matches the glob() the script did previously (this verifies that the sources list in the .gn file is up-to-date with the state on disk) - generate outputs list in gn from sources list, to make sure they're in sync - use an expicit --icd flag instead of doing `'icd' in path` - fail when failing to extract vk_version instead of silently using a default - some minor python style fixes Bug: chromium:910699,chromium:869348 Change-Id: I1e598f4566697a7f1ef56b040e52d0717f7ad075 Reviewed-on: https://chromium-review.googlesource.com/c/1358631 Reviewed-by: Jamie Madill <jmadill@chromium.org> Commit-Queue: Nico Weber <thakis@chromium.org>

  • ANGLE - Almost Native Graphics Layer Engine

    The goal of ANGLE is to allow users of multiple operating systems to seamlessly run WebGL and other OpenGL ES content by translating OpenGL ES API calls to one of the hardware-supported APIs available for that platform. ANGLE currently provides translation from OpenGL ES 2.0 and 3.0 to desktop OpenGL, OpenGL ES, Direct3D 9, and Direct3D 11. Support for translation from OpenGL ES to Vulkan is underway, and future plans include compute shader support (ES 3.1) and MacOS support.

    ANGLE v1.0.772 was certified compliant by passing the ES 2.0.3 conformance tests in October 2011. ANGLE also provides an implementation of the EGL 1.4 specification.

    ANGLE is used as the default WebGL backend for both Google Chrome and Mozilla Firefox on Windows platforms. Chrome uses ANGLE for all graphics rendering on Windows, including the accelerated Canvas2D implementation and the Native Client sandbox environment.

    Portions of the ANGLE shader compiler are used as a shader validator and translator by WebGL implementations across multiple platforms. It is used on Mac OS X, Linux, and in mobile variants of the browsers. Having one shader validator helps to ensure that a consistent set of GLSL ES shaders are accepted across browsers and platforms. The shader translator can be used to translate shaders to other shading languages, and to optionally apply shader modifications to work around bugs or quirks in the native graphics drivers. The translator targets Desktop GLSL, Direct3D HLSL, and even ESSL for native GLES2 platforms.
