From d1b4cc3ec5f8ddbac57ada58cbab36f5a0be38eb Mon Sep 17 00:00:00 2001 From: Andres Salomon Date: Mon, 28 Apr 2008 02:15:01 -0700 Subject: [PATCH] gxfb: stop sharing code with gx1fb We want to stop sharing stuff with gx1fb; it makes little sense. There were fields in geodefb_par that weren't being used, there was little point to the DC/VP ops callbacks, etc. This implements the following: - Create gxfb_par (based on geodefb_par), place it in gxfb.h - Drop display_gx.h and video_gx.h. The last few patches moved most stuff into gxfb.h anyways, so there was very little left. - Drop the geode_{dc,vid}_ops stuff. Un-static functions, add declarations to gxfb.h.
