Although for the properties here we seems to be in a pickle. These are defined in drm_blend.h which is not exported as part of the ABI. Yet the defines _are_ part of the ABI - see the lovely warning, which was added when someone broke and ABI and hence userspace. My suggestion - fix this in the kernel first. - Move the DRM_ROTATE* and DRM_REFLECT_* to an ABI header. Having a slight preference about drm_mode.h but drm.h should also be fine. - Optional: skim through for other properties that should be moved to the ABI headers. - Update libdrm as described in the README (please send patches if the documentation is not clear) Thanks Emil _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
