From d8cbf1adc12fe71e19c08ac6a74ce5df3ea3404f Mon Sep 17 00:00:00 2001 From: Rob Clark Date: Fri, 20 Sep 2019 14:58:49 -0700 Subject: freedreno/a6xx: do streamout only in binning pass Use VPC_SO_OVERRIDE to control whether we do streamout in binning or draw pass. Normally we want to do streamout in binning pass, except when there is a single tile and binning passed is skipped. Signed-off-by: Rob Clark Reviewed-by: Eric Anholt Reviewed-by: Kristian H.
