  "message": "drm/i915: Add support for precise vblank timestamping (v2)\n\nv2: Change IS_IRONLAKE to IS_GEN5 to adapt to 2.6.37\n\nThis patch adds new functions for use by the drm core:\n\n.get_vblank_timestamp() provides a precise timestamp\nfor the end of the most recent (or current) vblank\ninterval of a given crtc, as needed for the DRI2\nimplementation of the OML_sync_control extension.\nIt is a thin wrapper around the drm function\ndrm_calc_vbltimestamp_from_scanoutpos() which does\nalmost all the work.\n\n.get_scanout_position() provides the current horizontal\nand vertical video scanout position and \"in vblank\"\nstatus of a given crtc, as needed by the drm for use by\ndrm_calc_vbltimestamp_from_scanoutpos().\n\nThe patch modifies the pageflip completion routine\nto use these precise vblank timestamps as the timestamps\nfor pageflip completion events.\n\nThis code has been only tested on a HP-Mini Netbook with\nAtom processor and Intel 945GME gpu. The codepath for\n(IS_G4X(dev) || IS_GEN5(dev) || IS_GEN6(dev)) gpu\u0027s\nhas not been tested so far due to lack of hardware.\n\nSigned-off-by: Mario Kleiner \u003cmario.kleiner@tuebingen.mpg.de\u003e\nAcked-by: Jesse Barnes \u003cjbarnes@virtuousgeek.org\u003e\nSigned-off-by: Chris Wilson \u003cchris@chris-wilson.co.uk\u003e\n",
