  "message": "Implement GpuMemoryBuffers for EGL and GLX\n\nAdds GMB support for Linux/X11. ANGLE support will be added in\nfollowup(s). For now, support on EGL/GLX is enabled when\n--enable-native-gpu-memory-buffers is passed.\n\nMain code additions:\n* GbmSupportX11: ui/gfx/linux/gbm_support_x11.*\n  - Uses DRI3 to get an authenticated DRM fd. Creates a GbmDevice\n    with it.\n* GLImageGLXNativePixmap: ui/gl/gl_image_glx_native_pixmap.*\n  - Subclasses GlImageGLX.  Uses DRI3 to get a GLX pixmap from a\n    dma-buf.\n* ui/gl/gl_visual_picker_glx.*\n  - Figures out which GLXFBConfigs should be used for corresponding\n    gfx::BufferFormats.  Only BGR(A) formats are supported by GLX.\n\nGMB support used to be routed through gpu::GpuMemoryBufferSupport,\nwhich is basically just a switch statement over the various\ngfx::BufferFormats and gfx::BufferUsages. With X11, GMB support needs\nto be determined at runtime, and in the GPU process (since it depends\non the singleton GbmDevice and the GL implementation), so GMB support\nis put into gpu::GPUInfo, similar to how we\u0027re already doing with\nvisual IDs.\n\nBUG\u003d1031269\n\nChange-Id: Ie254e6c5646073be0cb76d549c115be274e4ef46\nReviewed-on: https://chromium-review.googlesource.com/c/chromium/src/+/1984712\nCommit-Queue: Thomas Anderson \u003cthomasanderson@chromium.org\u003e\nReviewed-by: Scott Violet \u003csky@chromium.org\u003e\nReviewed-by: Martin Barbella \u003cmbarbella@chromium.org\u003e\nReviewed-by: Mark Pearson \u003cmpearson@chromium.org\u003e\nReviewed-by: Jonathan Backer \u003cbacker@chromium.org\u003e\nReviewed-by: Kenneth Russell \u003ckbr@chromium.org\u003e\nReviewed-by: kylechar \u003ckylechar@chromium.org\u003e\nReviewed-by: Robert Kroeger \u003crjkroege@chromium.org\u003e\nCr-Commit-Position: refs/heads/master@{#736698}\n",
