From da136dc07ddb6147d181c96f475b94f6281efd73 Mon Sep 17 00:00:00 2001 From: Ilia Mirkin Date: Sat, 9 May 2015 03:26:07 -0400 Subject: [PATCH] nv50/ir: only enable mul saturate on G200+ Commit 44673512a84 enabled support for saturating fmul. However experimentally this does not seem to work on the older chips. Restrict the feature to G200 (NVA0) and later.
