Atm there's not much users of this (I guess they're still waiting for acks), and somehow I'd expect that there's some drivers which really want this (but I don't see any in this patch series). Looks good, but I'm a bit confused. -Daniel > --- > drivers/gpu/drm/drm_gem_framebuffer_helper.c | 6 +++++- > 1 file changed, 5 insertions(+), 1 deletion(-) > > diff --git a/drivers/gpu/drm/drm_gem_framebuffer_helper.c b/drivers/gpu/drm/drm_gem_framebuffer_helper.c > index aa8cb9bfa499..4d682a6e8bcb 100644 > --- a/drivers/gpu/drm/drm_gem_framebuffer_helper.c > +++ b/drivers/gpu/drm/drm_gem_framebuffer_helper.c > @@ -272,7 +272,8 @@ EXPORT_SYMBOL_GPL(drm_gem_fb_prepare_fb); > * @sizes: fbdev size description > * @pitch_align: Optional pitch alignment > * @obj: GEM object backing the framebuffer > - * @funcs: vtable to be used for the new framebuffer object > + * @funcs: Optional vtable to be used for the new framebuffer object when the > + * dirty callback is needed. > * > * This function creates a framebuffer from a &drm_fb_helper_surface_size > * description for use in the &drm_fb_helper_funcs.fb_probe callback. > @@ -300,6 +301,9 @@ drm_gem_fbdev_fb_create(struct drm_device *dev, > if (obj->size < mode_cmd.pitches[0] * mode_cmd.height) > return ERR_PTR(-EINVAL); > > + if (!funcs) > + funcs = &drm_gem_fb_funcs; > + > return drm_gem_fb_alloc(dev, &mode_cmd, &obj, 1, funcs); > } > EXPORT_SYMBOL(drm_gem_fbdev_fb_create); > -- > 2.14.2 > > _______________________________________________ > dri-devel mailing list > dri-devel@xxxxxxxxxxxxxxxxxxxxx > https://lists.freedesktop.org/mailman/listinfo/dri-devel -- Daniel Vetter Software Engineer, Intel Corporation http://blog.ffwll.ch _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
