This CL enable build d3d11 by default, if dawn is not build with chromium. d3d11 backend is not full implemented yet, so no tests will run against d3d11 backend. Bug: dawn:1705 Change-Id: Id689ab5168511af0f75f0b3537f246713de5ca45 Reviewed-on: https://dawn-review.googlesource.com/c/dawn/+/127260 Kokoro: Kokoro <noreply+kokoro@google.com> Reviewed-by: Austin Eng <enga@chromium.org> Commit-Queue: Peng Huang <penghuang@chromium.org>
