From 640b98286476123fd35f15221cc2dc6342f7032e Mon Sep 17 00:00:00 2001 From: Connor Abbott Date: Mon, 23 Mar 2026 14:30:22 -0400 Subject: [PATCH] tu: Disable LRZ when resuming if the GPU doesn't support tracking We rely on tu_lrz_flush_valid_at_suspending_rp_boundary() to make sure that subsequent resuming renderpasses get the correct LRZ state. However this doesn't work on early a6xx GPUs without tracking support. Disable LRZ in this case, similar to secondaries.
