7 | * This file is based on two CyberVision64 frame buffer device drivers | ||
8 | * | ||
9 | * The second CyberVision64 frame buffer device (cvision.c cvision_core.c): | ||
10 | * | ||
11 | * Copyright (c) 1997 Antonio Santos | ||
12 | * | ||
13 | * Released as a patch to 2.1.35, but never included in the source tree. | ||
14 | * This is based on work from the NetBSD CyberVision64 frame buffer driver | ||
15 | * and support files (grf_cv.c, grf_cvreg.h, ite_cv.c): | ||
16 | * Permission to use the source of this driver was obtained from the | ||

32 | * - 22 Dec 95: Original version by Martin Apel | ||
33 | * - 05 Jan 96: Geert: integration into the current source tree | ||
34 | * - 01 Aug 98: Alan: Merge in code from cvision.c and cvision_core.c | ||
35 | * $Log: cyberfb.c,v $ | ||
36 | * Revision 1.6 1998/09/11 04:54:58 abair | ||
37 | * Update for 2.1.120 change in include file location. | ||
38 | * Clean up for public release. | ||
39 | * | ||
40 | * Revision 1.5 1998/09/03 04:27:13 abair | ||
41 | * Move cv64_load_video_mode to cyber_set_video so a new video mode is install | ||
42 | * with each change of the 'var' data. | ||
43 | * | ||
44 | * Revision 1.4 1998/09/01 00:31:17 abair | ||
45 | * Put in a set of default 8,16,24 bpp modes and map cyber8,16 to them. | ||
46 | * Update operations with 'par' to handle a more complete set of parameter | ||
47 | * values for encode/decode process. | ||
48 | * | ||
49 | * Revision 1.3 1998/08/31 21:31:33 abair | ||
50 | * Swap 800x490 for 640x480 video mode and more cleanup. | ||
51 | * Abandon idea to resurrect "custom" mode setting via kernel opts, | ||
52 | * instead work on making use of fbset program to do this. | ||
53 | * | ||
54 | * Revision 1.2 1998/08/31 06:17:08 abair | ||
55 | * Make updates for changes in cyberfb.c released in 2.1.119 | ||
56 | * and do some cleanup of the code. | ||
57 | * | ||
58 | * Revision 1.1 1998/08/29 18:38:31 abair | ||
59 | * Initial revision | ||
60 | * | ||
61 | * Revision 1.3 1998/08/17 06:21:53 abair | ||
62 | * Remove more redundant code after merging in cvision_core.c | ||
63 | * Set blanking by colormap to pale red to detect this vs trying to | ||
64 | * use video blanking. More formating to Linux code style. | ||
65 | * | ||
66 | * Revision 1.2 1998/08/15 17:51:37 abair | ||
67 | * Added cvision_core.c code from 2.1.35 patches. | ||
68 | * Changed to compile correctly and switch to using initialization | ||
69 | * code. Added debugging and dropping of duplicate code. | ||
