From 341278f069a54a173fa646b16e0b68eefd28e5ed Mon Sep 17 00:00:00 2001 From: Samuel Pitoiset Date: Tue, 16 Nov 2021 11:08:15 +0100 Subject: [PATCH] radv: disable HTILE for D32S8 format and mipmaps on GFX10 Stencil texturing with HTILE doesn't work with mipmapping on Navi10-14, it's a hw bug. RadeonSI and PAL have a workaround too. This fixes 35 piglit failures with Zink on Navi10.
