JOHANNES HEIDENHAIN GmbH Dr.-Johannes-Heidenhain-Str. 5 83301 Traunreut, Deutschland http://www.heidenhain.de Author: Andreas Lampersperger <Lampersperger.andreas@xxxxxxxxxxxxx> libdrm: Provide DRM_MODE_FB_DIRTY_MAX_CLIPS When calling drmModeDirtyFB(..) on linux, it fails when num_clips are more than DRM_MODE_FB_DIRTY_MAX_CLIPS (value: 256). But there is no way to check this for xf86-video-* drivers, because when including drm_mode.h, you get the drm_mode.h from .../include/libdrm/drm_mode.h and not .../include/drm/drm_mode.h. This commit adds the define DRM_MODE_FB_DIRTY_MAX_CLIPS also to libdrm/drm_mode.h, so applications/drivers linking against libdrm can use it to check the proper use of drmModeDirtyFB(..)
