From 96f80c8d4d97771b5450d6d15ddb3b172c7d69cf Mon Sep 17 00:00:00 2001 From: Bas Nieuwenhuizen Date: Sun, 8 Oct 2017 21:58:23 +0200 Subject: [PATCH] radv: Only set the MTYPE flags on GFX9+. Older kernels fail the va_op with this flag set. If the kernel supports GFX9 usefully, it will also support this flag.
