  "message": "Reduce/Eliminate line buffer for loop-restoration.\n\nThis patch forces the vertical filtering for the top and bottom\nrows of a processing unit for the Wiener filter to not use border\nmore than what is set in the WIENER_BORDER_VERT macro.\nThis macro is currently set at 0 to eliminate line buffer completely,\nbut it could be increased to 1 or 2 to use limited line buffers\nif the coding efficiency is affected too much with a 0 line-buffer.\n\nAlso, for the sgr filter we added the option of using overlapping\nwindows horizonttally and vertically to improve coding efficiency.\nThe vertical border used is set by the SGRPROJ_BORDER_VERT\nmacro, while the horizontal border can be set by the\nSGRPROJ_BORDER_HORZ macro set at 2, the max needed. Currently we do not\nrecommend changing SGRPROJ_BORDER_HORZ below 2.\n\nThe overall line buffer requirement for LR is twice the max of\nWIENER_BORDER_VERT and SGRPROJ_BORDER_VERT.\nCurrently both are set as 0, eliminating line buffers completely.\n\nAlso this patch extends borders consistently before CDEF / LR.\n\nChange-Id: Ie58a98c784a0db547627b9cfcf55f018c30e8e79\n",
