It won't work, but I wouldn't say it's breaking anything, since gbm never supported YUV surfaces. For planar YUV buffers, creating the gbm_bo from an EGLImage won't work, since there are now several EGLImages per wl_buffer. Instead I've used the attached patch to create a gbm_bo directly from a wl_buffer. I've tested it in weston with YUYV buffers (which is what SNB supports and isn't a planar format). For planar formats we'll need to also add API to gbm to get offsets and stride of the planes in the gbm_bo, so we can feed drmModeAddFB2 those. Kristian
