From 5e1b8ed88ae8fb8b697515140f7a00d022ac2db0 Mon Sep 17 00:00:00 2001 From: Michel Daenzer Date: Tue, 29 Oct 2002 13:49:26 +0000 Subject: preserve CRTC{,2}_OFFSET_CNTL in 2D driver to avoid bad effects when pageflipping after a mode switch take current page into account in AdjustFrame(); writing the CRTC offset via the CP was probably a bad idea as this can happen asynchronously, reverted take frame offset into account when flipping pages handle CRTC2 as well for pageflipping (untested) preserve GEN_INT_CNTL on mode switches to prevent interrupts from getting disabled --- shared/drm_sarea.h | 57 +++++++++++++++++++++++++++++++++++++++++++++++++++ shared/radeon_drm.h | 1 + shared/radeon_drv.h | 4 ++-- shared/radeon_state.c | 38 +++++++++++++++++----------------- 4 files changed, 79 insertions(+), 21 deletions(-) create mode 100644 shared/drm_sarea.h (limited to 'shared') diff --git a/shared/drm_sarea.h b/shared/drm_sarea.h new file mode 100644 index 00000000..cee48eee --- /dev/null +++ b/shared/drm_sarea.h @@ -0,0 +1,57 @@ +/* sarea.h -- SAREA definitions -*- linux-c -*- + * + * Copyright 2002 Tungsten Graphics, Inc., Cedar Park, Texas. + * All Rights Reserved. + * + * Permission is hereby granted, free of charge, to any person obtaining a + * copy of this software and associated documentation files (the "Software"), + * to deal in the Software without restriction, including without limitation + * the rights to use, copy, modify, merge, publish, distribute, sublicense, + * and/or sell copies of the Software, and to permit persons to whom the + * Software is furnished to do so, subject to the following conditions: + * + * The above copyright notice and this permission notice (including the next + * paragraph) shall be included in all copies or substantial portions of the + * Software. + * + * THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR + * IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, + * FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
