From 577e114e4654c645fcb1673afe5bb849deccb2b3 Mon Sep 17 00:00:00 2001 From: Brian Paul Date: Thu, 6 Apr 2017 14:55:53 -0600 Subject: [PATCH] svga: fail screen creation if HW version is too old Tested by verifying 3D acceleration works with HWv8 but not earlier. For HWv7 and older we get the GDI Generic renderer.
