4 * Linux framebuffer driver for Intel(R) 830M/845G/852GM/855GM/865G/915G/915GM/
5 * 945G/945GM/945GME/965G/965GM integrated graphics chips.
7 * Copyright © 2002, 2003 David Dawes <dawes@xfree86.org>
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).
22 /* $DHD: intelfb/intelfbdrv.c,v 1.20 2003/06/27 15:17:40 dawes Exp $ */
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)
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)
36 * 01/2003 - Version 0.3.0: fbcon acceleration support added. Module
37 * option handling added. (David Dawes)
39 * 01/2003 - Version 0.4.0: fbcon HW cursor support added. (David Dawes)
41 * 01/2003 - Version 0.4.1: Add auto-generation of built-in modes.
44 * 02/2003 - Version 0.4.2: Add check for active non-CRT devices, and
45 * mode validation checks. (David Dawes)
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.
51 * 02/2003 - Version 0.4.4: Monitor DPMS support. (David Dawes)
53 * 02/2003 - Version 0.4.5: Basic XFree86 + fbdev working. (David Dawes)
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)
58 * 02/2003 - Version 0.6.0: Split out HW-specifics into a separate file.
61 * 02/2003 - Version 0.7.0: Test on 852GM/855GM. Acceleration and HW
62 * cursor are disabled on this platform. (David Dawes)
64 * 02/2003 - Version 0.7.1: Test on 845G. Acceleration is disabled
65 * on this platform. (David Dawes)
67 * 02/2003 - Version 0.7.2: Test on 830M. Acceleration and HW
68 * cursor are disabled on this platform. (David Dawes)
70 * 02/2003 - Version 0.7.3: Fix 8-bit modes for mobile platforms
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.
78 * 02/2003 - Version 0.7.5: Add basic package/install scripts based on the
79 * DRI packaging scripts. (David Dawes)
81 * 04/2003 - Version 0.7.6: Fix typo that affects builds with SMP-enabled
82 * kernels. (David Dawes, reported by Anupam).
84 * 06/2003 - Version 0.7.7:
85 * Fix Makefile.kernel build problem (Tsutomu Yasuda).
86 * Fix mis-placed #endif (2.4.21 kernel).
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
94 * 10/2004 - Version 0.9.1
95 * Use module_param instead of old MODULE_PARM
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
103 * 04/2008 - Version 0.9.5
104 * Add support for 965G/965GM. (Maik Broemme <mbroemme@plusserver.de>)
106 * 08/2008 - Version 0.9.6
107 * Add support for 945GME. (Phil Endecott <spam_from_intelfb@chezphil.org>)
