Reland "Add support for Linux vulkan backend with VK_KHR_display" This is a reland of a7bb6a9b15ddeb8497523f8871deb25de2676d9f Original change's description: > Add support for Linux vulkan backend with VK_KHR_display > > Implement Linux simple display mode with vulkan backend > through VK_KHR_display. > > Added value 'EGL_PLATFORM_VULKAN_DISPLAY_MODE_SIMPLE_ANGLE' for > attribute EGL_PLATFORM_ANGLE_NATIVE_PLATFORM_TYPE_ANGLE to identify > the new simple display mode. Also reserved > EGL_PLATFORM_VULKAN_DISPLAY_MODE_HEADLESS_ANGLE for headless mode. > > How to enable: > Add > > ``` > use_x11=false > angle_vulkan_display_mode="simple" # default value > ``` > > into args.gn, then compile with linux vulkan args. > > Bug: angleproject:5214 > Change-Id: I1247585b9de8b55df106aba99322281f1c183203 > Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/2494320 > Commit-Queue: Jamie Madill <jmadill@chromium.org> > Reviewed-by: Jamie Madill <jmadill@chromium.org> > Reviewed-by: Shahbaz Youssefi <syoussefi@chromium.org> Bug: angleproject:5214 Change-Id: I3921f6cb292c86658f39e739a878baad1ef64dba Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/2515327 Commit-Queue: Xiaoxuan Liu <xiaoxuan.liu@arm.com> Commit-Queue: Jamie Madill <jmadill@chromium.org> Reviewed-by: Jamie Madill <jmadill@chromium.org>
