From e1745e0bd93d25c5d70bd1de884a86a0ade0adf9 Mon Sep 17 00:00:00 2001 From: Caio Oliveira Date: Thu, 23 Apr 2026 00:03:20 -0700 Subject: [PATCH] brw: Fix max_dispatch_width collection for CS with variable size The intention of the original commit was to make all the shaders report the same max_dispatch_width. When CS has multiple variants, this was not happening as expected.
