Technically this is not correct. There is no requirement for the planes to cover the whole CRTC. Nor is there a requirement to use only 2 rectangles to cover the screen. As such, it is perfectly fine in mode_valid, if CRTC is wider than 2x max_linewidth. It would be an error if the user tries to stretch 2 rectangles in such a case. > > Signed-off-by: Vishnu Saini <[email protected]> > --- > drivers/gpu/drm/msm/disp/dpu1/dpu_crtc.c | 12 ++++++++---- > 1 file changed, 8 insertions(+), 4 deletions(-) > -- With best wishes Dmitry
