Note KGSL doesn't enable AMSBC for UBWC_6_0 and A8xx (but does for A8xx+ UBWC3..5) The initial commit adding A6xx support to KGSL has this hunk: + case KGSL_UBWC_3_0: + mode = 0; + amsbc = 1; /* Only valid for A640 and A680 */ + break; That was in a time where A640/680 (8150/8180 respectively, with UBWC3_x) may have still been under heavy development - this initial driver was targeting A630/SDM845 (UBWC2), so perhaps that's not really meaningful Konrad
