Message : Reland "Vulkan: Add semaphores test to VulkanExternalImageTest" This is a reland of 69e46942563b30be8a79512252e92fcf00c1a522 Original change's description: > Vulkan: Add semaphores test to VulkanExternalImageTest > > Add a more substantial test that uses semaphores to > VulkanExternalImageTest. > > It's still just a clear in GL, which exposed a bug that a staged clear > wasn't be flushed by a call to glSignalSemaphoreEXT. > > Bug: angleproject:3289 > Change-Id: Id938eaf2c8c20cb0ae9fb948fbfcf3448980b577 > Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/2195684 > Commit-Queue: Michael Spang <spang@chromium.org> > Reviewed-by: Jamie Madill <jmadill@chromium.org> > Reviewed-by: Geoff Lang <geofflang@chromium.org> Bug: angleproject:3289 Change-Id: Idce1e8944b72445c92be9ad08d8c5869ca0b7df2 Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/2197735 Reviewed-by: Geoff Lang <geofflang@chromium.org> Commit-Queue: Michael Spang <spang@chromium.org>
