Summary Provide DRM_MODE_FB_DIRTY_MAX_CLIPS in drm_mode.h
Product DRI
Version XOrg git
Hardware x86 (IA32)
OS Linux (All)

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 /usr/include/libdrm/drm_mode.h and not /usr/include/drm/drm_mode.h.

Please add

#define DRM_MODE_FB_DIRTY_MAX_CLIPS 256 

to your drm_mode.h, to allow xf86-video-* drivers to check parameters before
calling drmModeDirtyFB(...).
