From 3512f976d252bd5d07d04e9e157f0cd210c959a0 Mon Sep 17 00:00:00 2001 From: Ville Syrjälä Date: Wed, 24 Apr 2013 18:52:34 +0300 Subject: drm: Add struct drm_rect and assorted utility functions MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit struct drm_rect represents a simple rectangle. The utility functions are there to help driver writers. v2: Moved the region stuff into its own file, made the smaller funcs static inline, used 64bit maths in the scaled clipping function to avoid overflows (instead it will saturate to INT_MIN or INT_MAX). v3: Renamed drm_region to drm_rect, drm_region_clip to drm_rect_intersect, and drm_region_subsample to drm_rect_downscale. v4: Renamed some function parameters, improve kernel-doc comments a bit, and actually generate documentation for drm_rect.[ch]. v5: s/RETUTRNS/RETURNS/ Reviewed-by: Laurent Pinchart Reviewed-by: Chris Wilson Signed-off-by: Ville Syrjälä Acked-by: Dave Airlie Signed-off-by: Daniel Vetter --- Documentation/DocBook/drm.tmpl | 2 ++ 1 file changed, 2 insertions(+) (limited to 'Documentation/DocBook') diff --git a/Documentation/DocBook/drm.tmpl b/Documentation/DocBook/drm.tmpl index f9df3b872c16..7c7af25b330c 100644 --- a/Documentation/DocBook/drm.tmpl +++ b/Documentation/DocBook/drm.tmpl @@ -1653,6 +1653,8 @@ void intel_crt_init(struct drm_device *dev) KMS API Functions !Edrivers/gpu/drm/drm_crtc.c +!Edrivers/gpu/drm/drm_rect.c +!Finclude/drm/drm_rect.h -- cgit v1.2.3
