fbdev/intelfb: Remove driver
From looking at the PCI IDs, every device supported by intelfb is also supported by i915. Anyone still using intelfb should please move on to i915, which does everything intelfb does but better. Removing intelfb is motivated by the driver's excessive use of the global screen_info state. The state belongs to architecture and firmware code; device drivers should not attempt to access it. But fixing intelfb would require a significant change in the driver's probing logic. As intelfb has been obsolete for nearly 2 decades, it is probably not worth the effort. Let's just remove it. Also remove the related documentation. Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Acked-by: Maik Broemme <mbroemme@libmpq.org> Signed-off-by: Helge Deller <deller@gmx.de>

Intel 830M/845G/852GM/855GM/865G/915G/945G Framebuffer driver
|
||||
=============================================================
|
||||
|
||||
A. Introduction
|
||||
===============
|
||||
|
||||
This is a framebuffer driver for various Intel 8xx/9xx compatible
|
||||
graphics devices. These would include:
|
||||
|
||||
- Intel 830M
|
||||
- Intel 845G
|
||||
- Intel 852GM
|
||||
- Intel 855GM
|
||||
- Intel 865G
|
||||
- Intel 915G
|
||||
- Intel 915GM
|
||||
- Intel 945G
|
||||
- Intel 945GM
|
||||
- Intel 945GME
|
||||
- Intel 965G
|
||||
- Intel 965GM
|
||||
|
||||
B. List of available options
|
||||
=============================
|
||||
|
||||
a. "video=intelfb"
|
||||
enables the intelfb driver
|
||||
|
||||
Recommendation: required
|
||||
|
||||
b. "mode=<xres>x<yres>[-<bpp>][@<refresh>]"
|
||||
select mode
|
||||
|
||||
Recommendation: user preference
|
||||
(default = 1024x768-32@70)
|
||||
|
||||
c. "vram=<value>"
|
||||
select amount of system RAM in MB to allocate for the video memory
|
||||
if not enough RAM was already allocated by the BIOS.
|
||||
|
||||
Recommendation: 1 - 4 MB.
|
||||
(default = 4 MB)
|
||||
|
||||
d. "voffset=<value>"
|
||||
select at what offset in MB of the logical memory to allocate the
|
||||
framebuffer memory. The intent is to avoid the memory blocks
|
||||
used by standard graphics applications (XFree86). Depending on your
|
||||
usage, adjust the value up or down, (0 for maximum usage, 63/127 MB
|
||||
for the least amount). Note, an arbitrary setting may conflict
|
||||
with XFree86.
|
||||
|
||||
Recommendation: do not set
|
||||
(default = 48 MB)
|
||||
|
||||
e. "accel"
|
||||
enable text acceleration. This can be enabled/reenabled anytime
|
||||
by using 'fbset -accel true/false'.
|
||||
|
||||
Recommendation: enable
|
||||
(default = set)
|
||||
|
||||
f. "hwcursor"
|
||||
enable cursor acceleration.
|
||||
|
||||
Recommendation: enable
|
||||
(default = set)
|
||||
|
||||
g. "mtrr"
|
||||
enable MTRR. This allows data transfers to the framebuffer memory
|
||||
to occur in bursts which can significantly increase performance.
|
||||
Not very helpful with the intel chips because of 'shared memory'.
|
||||
|
||||
Recommendation: set
|
||||
(default = set)
|
||||
|
||||
h. "fixed"
|
||||
disable mode switching.
|
||||
|
||||
Recommendation: do not set
|
||||
(default = not set)
|
||||
|
||||
The binary parameters can be unset with a "no" prefix, example "noaccel".
|
||||
The default parameter (not named) is the mode.
|
||||
|
||||
C. Kernel booting
|
||||
=================
|
||||
|
||||
Separate each option/option-pair by commas (,) and the option from its value
|
||||
with an equals sign (=) as in the following::
|
||||
|
||||
video=intelfb:option1,option2=value2
|
||||
|
||||
Sample Usage
|
||||
------------
|
||||
|
||||
In /etc/lilo.conf, add the line::
|
||||
|
||||
append="video=intelfb:mode=800x600-32@75,accel,hwcursor,vram=8"
|
||||
|
||||
This will initialize the framebuffer to 800x600 at 32bpp and 75Hz. The
|
||||
framebuffer will use 8 MB of System RAM. hw acceleration of text and cursor
|
||||
will be enabled.
|
||||
|
||||
Remarks
|
||||
-------
|
||||
|
||||
If setting this parameter doesn't work (you stay in a 80x25 text-mode),
|
||||
you might need to set the "vga=<mode>" parameter too - see vesafb.txt
|
||||
in this directory.
|
||||
|
||||
|
||||
D. Module options
|
||||
==================
|
||||
|
||||
The module parameters are essentially similar to the kernel
|
||||
parameters. The main difference is that you need to include a Boolean value
|
||||
(1 for TRUE, and 0 for FALSE) for those options which don't need a value.
|
||||
|
||||
Example, to enable MTRR, include "mtrr=1".
|
||||
|
||||
Sample Usage
|
||||
------------
|
||||
|
||||
Using the same setup as described above, load the module like this::
|
||||
|
||||
modprobe intelfb mode=800x600-32@75 vram=8 accel=1 hwcursor=1
|
||||
|
||||
Or just add the following to a configuration file in /etc/modprobe.d/::
|
||||
|
||||
options intelfb mode=800x600-32@75 vram=8 accel=1 hwcursor=1
|
||||
|
||||
and just do a::
|
||||
|
||||
modprobe intelfb
|
||||
|
||||
|
||||
