From 308e5bcbdb10452e8aba31aa21432fb67ee46d72 Mon Sep 17 00:00:00 2001 From: Jesse Barnes Date: Mon, 14 Nov 2011 14:51:28 -0800 Subject: drm: add an fb creation ioctl that takes a pixel format v5 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit To properly support the various plane formats supported by different hardware, the kernel must know the pixel format of a framebuffer object. So add a new ioctl taking a format argument corresponding to a fourcc name from the new drm_fourcc.h header file. Implement the fb creation hooks in terms of the new mode_fb_cmd2 using helpers where the old bpp/depth values are needed. v2: create DRM specific fourcc header file for sharing with libdrm etc v3: fix rebase failure and use DRM fourcc codes in intel_display.c and update commit message v4: make fb_cmd2 handle field into an array for multi-object formats pull in Ville's fix for the memcpy in drm_plane_init apply Ville's cleanup to zero out fb_cmd2 arg in drm_mode_addfb v5: add 'flags' field for interlaced support (from Ville) Signed-off-by: Ville Syrjälä Acked-by: Alan Cox Reviewed-by: Rob Clark Signed-off-by: Jesse Barnes Signed-off-by: Dave Airlie --- include/drm/drm_fourcc.h | 63 ++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 63 insertions(+) create mode 100644 include/drm/drm_fourcc.h (limited to 'include/drm/drm_fourcc.h') diff --git a/include/drm/drm_fourcc.h b/include/drm/drm_fourcc.h new file mode 100644 index 0000000..48c3d10 --- /dev/null +++ b/include/drm/drm_fourcc.h @@ -0,0 +1,63 @@ +/* + * Copyright 2011 Intel Corporation + * + * 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.
