Patch looks good. Any nitpicks can be tweaked at a later stage. Rb and pushed to master. Aside: libdrm following X/Wayland in that it lacks contributor/push access docs. Might be worth, copying the Mesa ones and adding a doc in-tree. Thanks Emil

If "-a" option is set this make modetest use atomic API instead of legacy API. Test the frame rate ("-v") it does a loop and swap between two framebuffer for each active planes. Signed-off-by: Benjamin Gaignard <benjamin.gaignard@linaro.org> --- version 3: - merge atomic code into modetest itself - do not change build systems version 2 : - make modetest_atomic compile with meson and Android version 1: - add dedicated modetest_atomic tool to test atomic API tests/modetest/modetest.c | 349 ++++++++++++++++++++++++++++++++++++++++++---- 1 file changed, 321 insertions(+), 28 deletions(-)
