            Bug ID: 90898
           Summary: Provide DRM_MODE_FB_DIRTY_MAX_CLIPS in drm_mode.h
           Product: DRI
           Version: XOrg git
          Hardware: x86 (IA32)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: libdrm
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: lampersperger.andreas@heidenhain.de

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(...).

Hi Andreas, afaict the define has found its way into the header. Admittedly in
a slightly different manner.
