I have sent a series to add some pixel formats: https://lore.kernel.org/all/20250115-xilinx-formats-v2-0-160327ca652a at ideasonboard.com/ Let's look at XV15. It's similar to NV12, but 10 bits per component, and some packing and padding. First plane: 3 pixels in a 32 bit group Second plane: 3 pixels in a 64 bit group, 2x2 subsampled So, on average, a pixel on the first plane takes 32 / 3 = 10.666... bits on a line. That's not a usable number...

Call drm_mode_size_dumb() to compute dumb-buffer scanline pitch and buffer size. Align the pitch according to hardware requirements.
