  Message : Revert "Vulkan: Port renderer to Fuchsia" This reverts commit 991d1cfb5e5a2f20a46961da3ad85b95da30b88a. Reason for revert: Failing compile on the fuchsia bots on the ANGLE auto-roller. https://ci.chromium.org/p/chromium/builders/luci.chromium.try/fuchsia_x64/209198 In file included from ../../third_party/angle/util/fuchsia/ScenicWindow.cpp:10: In file included from ../../third_party/angle/util/fuchsia/ScenicWindow.h:13: In file included from gen/third_party/fuchsia-sdk/sdk/fidl/fuchsia/ui/policy/cpp/fidl.h:5: In file included from ../../third_party/fuchsia-sdk/sdk/pkg/fidl_cpp/include/lib/fidl/cpp/internal/header.h:12: ../../third_party/fuchsia-sdk/sdk/pkg/fit/include/lib/fit/function.h:135:6: error: extra ';' after member function definition [-Werror,-Wextra-semi] }; ^ 1 error generated. Original change's description: > Vulkan: Port renderer to Fuchsia > > Add DisplayVk and WindowSurfaceVk subclasses for Fuchsia to the vulkan > renderer, as well as an implementation of OSWindow that renders > fullscreen for the test suite. > > Disallow use of the vulkan loader from third_party as Fuchsia uses a fork > of the loader and has not sent those changes upstream yet. > > Add a small wayland-inspired library libfuchsia-egl to provide a type > "struct fuchsia_egl_window" to use as EGLNativeWindowType. This type > combines a zx_handle_t to an image pipe channel and a surface size. > > Image pipes can only be used once to create a VkSurfaceKHR. This means we > have to recreate the pipe in tests that call eglCreateWindowSurface more > than once with a single OSWindow, or the second call will fail. Add a > resetNativeWindow() method to accomplish this. > > BUG=angleproject:2475 > TEST=angle_end2end_tests on Fuchsia > > Change-Id: I71a613a362dd1c8aada49a3c02ae461e064457bf > Reviewed-on: https://chromium-review.googlesource.com/c/1446496 > Commit-Queue: Michael Spang <spang@chromium.org> > Reviewed-by: Jamie Madill <jmadill@chromium.org> TBR=spang@chromium.org,geofflang@chromium.org,jmadill@chromium.org,syoussefi@chromium.org Change-Id: I2d9abefa9db5363ba63a17c1773d0e147040d055 No-Presubmit: true No-Tree-Checks: true No-Try: true Bug: angleproject:2475 Reviewed-on: https://chromium-review.googlesource.com/c/1465761 Reviewed-by: Jamie Madill <jmadill@chromium.org> Commit-Queue: Jamie Madill <jmadill@chromium.org>
