From d6209a50bb13a40c0823f4c53eb1566328ba6630 Mon Sep 17 00:00:00 2001 From: "Kristian H. Kristensen" Date: Tue, 22 Oct 2019 16:24:26 -0700 Subject: freedreno: Don't count primitives for patches The gallium helper doesn't like patches and we can't determine how many primitives it gets tessellated into anyway. On gens where we have tessellation, we get the prim count from a HW counter so just skip counting on the CPU. Signed-off-by: Kristian H.
