11 | * This driver consists of two parts. The first part (intelfbdrv.c) provides | |
12 | * the basic fbdev interfaces, is derived in part from the radeonfb and | |
13 | * vesafb drivers, and is covered by the GPL. The second part (intelfbhw.c) | |
14 | * provides the code to program the hardware. Most of it is derived from | |
15 | * the i810/i830 XFree86 driver. The HW-specific code is covered here | |
16 | * under a dual license (GPL and MIT/XFree86 license). | |

25 | * Changes: | |
26 | * 01/2003 - Initial driver (0.1.0), no mode switching, no acceleration. | |
27 | * This initial version is a basic core that works a lot like | |
28 | * the vesafb driver. It must be built-in to the kernel, | |
29 | * and the initial video mode must be set with vga=XXX at | |
30 | * boot time. (David Dawes) | |
31 | * | |
32 | * 01/2003 - Version 0.2.0: Mode switching added, colormap support | |
33 | * implemented, Y panning, and soft screen blanking implemented. | |
34 | * No acceleration yet. (David Dawes) | |
35 | * | |
36 | * 01/2003 - Version 0.3.0: fbcon acceleration support added. Module | |
37 | * option handling added. (David Dawes) | |
38 | * | |
39 | * 01/2003 - Version 0.4.0: fbcon HW cursor support added. (David Dawes) | |
40 | * | |
41 | * 01/2003 - Version 0.4.1: Add auto-generation of built-in modes. | |
42 | * (David Dawes) | |
43 | * | |
44 | * 02/2003 - Version 0.4.2: Add check for active non-CRT devices, and | |
45 | * mode validation checks. (David Dawes) | |
46 | * | |
47 | * 02/2003 - Version 0.4.3: Check when the VC is in graphics mode so that | |
48 | * acceleration is disabled while an XFree86 server is running. | |
49 | * (David Dawes) | |
50 | * | |
51 | * 02/2003 - Version 0.4.4: Monitor DPMS support. (David Dawes) | |
52 | * | |
53 | * 02/2003 - Version 0.4.5: Basic XFree86 + fbdev working. (David Dawes) | |
54 | * | |
55 | * 02/2003 - Version 0.5.0: Modify to work with the 2.5.32 kernel as well | |
56 | * as 2.4.x kernels. (David Dawes) | |
57 | * | |
58 | * 02/2003 - Version 0.6.0: Split out HW-specifics into a separate file. | |
59 | * (David Dawes) | |
60 | * | |
61 | * 02/2003 - Version 0.7.0: Test on 852GM/855GM. Acceleration and HW | |
62 | * cursor are disabled on this platform. (David Dawes) | |
63 | * | |
64 | * 02/2003 - Version 0.7.1: Test on 845G. Acceleration is disabled | |
65 | * on this platform. (David Dawes) | |
66 | * | |
67 | * 02/2003 - Version 0.7.2: Test on 830M. Acceleration and HW | |
68 | * cursor are disabled on this platform. (David Dawes) | |
69 | * | |
70 | * 02/2003 - Version 0.7.3: Fix 8-bit modes for mobile platforms | |
71 | * (David Dawes) | |
72 | * | |
73 | * 02/2003 - Version 0.7.4: Add checks for FB and FBCON_HAS_CFB* configured | |
74 | * in the kernel, and add mode bpp verification and default | |
75 | * bpp selection based on which FBCON_HAS_CFB* are configured. | |
76 | * (David Dawes) | |
77 | * | |
78 | * 02/2003 - Version 0.7.5: Add basic package/install scripts based on the | |
79 | * DRI packaging scripts. (David Dawes) | |
80 | * | |
81 | * 04/2003 - Version 0.7.6: Fix typo that affects builds with SMP-enabled | |
82 | * kernels. (David Dawes, reported by Anupam). | |
83 | * | |
84 | * 06/2003 - Version 0.7.7: | |
85 | * Fix Makefile.kernel build problem (Tsutomu Yasuda). | |
86 | * Fix mis-placed #endif (2.4.21 kernel). | |
87 | * | |
88 | * 09/2004 - Version 0.9.0 - by Sylvain Meyer | |
89 | * Port to linux 2.6 kernel fbdev | |
90 | * Fix HW accel and HW cursor on i845G | |
91 | * Use of agpgart for fb memory reservation | |
92 | * Add mtrr support | |
93 | * | |
94 | * 10/2004 - Version 0.9.1 | |
95 | * Use module_param instead of old MODULE_PARM | |
96 | * Some cleanup | |
97 | * | |
98 | * 11/2004 - Version 0.9.2 | |
99 | * Add vram option to reserve more memory than stolen by BIOS | |
100 | * Fix intelfbhw_pan_display typo | |
101 | * Add __initdata annotations | |
