From 97f5721bfc4bbbce5c3a39cf48eeb6ad1fb9cf97 Mon Sep 17 00:00:00 2001
From: Jose Maria Casanova Crespo <jmcasanova@igalia.com>
Date: Mon, 15 Apr 2024 12:22:31 +0200
Subject: [PATCH] broadcom/compiler: needs_quad_helper_invocation enable
PER_QUAD TMU access
We take advantage of the needs_quad_helper_invocation information to
only enable the PER_QUAD TMU access on Fragment Shaders when it is needed.
PER_QUAD access is also disabled on stages different to fragment shader.
Being enabled was causing MMU errors when TMU was doing indexed by vertexid
reads on disabled lanes on vertex stage. This problem was exercised by some
shaders from the GTK new GSK_RENDERER=ngl that were accessing a constant buffer
offset[6], but having PER_QUAD enabled on the TMU access by VertexID was
doing hidden incorrect access to not existing vertex 6 and 7 as TMU was
accessing the full quad.
