From 8a68ec14536c802b2d869f2356d978346bf234f4 Mon Sep 17 00:00:00 2001 From: Mika Kuoppala Date: Tue, 11 Aug 2015 15:25:37 +0300 Subject: lib/rendercopy_gen9: WaBindlessSurfaceStateModifyEnable Don't set the size of bindless surface state on rendercopy. And as of doing so, take into account the workaround for setting the command size. This was tried during hunting for https://bugs.freedesktop.org/show_bug.cgi?id=89959. But no impact was found.
