Re: [Linux-fbdev-users] Where to put fbset command during system boot up

[Unger R. <ric...@te...>]

You need to add a parameter to your kernel boot line in your GRUB or =
LILO configuration.

Something like "video=3Dnscfb:vmode:1024x768-32,vfreq=3D75"

That's assuming you are using the GEODE framebuffer driver, not vesa...

Attached to the end of this email is the GEODE Framebuffer README file =
from the amd.com site. It has a pretty good description of how to set it =

PRODUCT INFORMATION
-------------------------------------------------------------------------=
----
This driver is the frame buffer graphics device driver for the Geode GX=20
processors (GX 533@1.1W, GX 500@1.0W, GX 466@0.9W), Geode SC1200/SC1201, =
SC2200,=20
and SC3200 processors, and the GX1 processors. (Hereafter referred to as =
Geode=20
processor unless otherwise specified.) The driver works with the Geode =
Linux=20
graphics driver architecture and has been tested with Linux kernel =
2.4.17.=20


Features
--------
Geode GX processors (GX 533@1.1W, GX 500@1.0W, GX 466@0.9W) supported=20
display modes:

- 800x600 @ 56, 60, 72, 75, 85 Hz, 8, 16, and 32 bpp
- 1024x768 @ 60, 70, 75, 85 Hz, 8, 16, and 32 bpp
- 1152x864 @ 75 Hz 8, 16, and 32 bpp
- 1280x1024 @ 60, 75, 85 Hz, 8, 16, and 32 bpp
- 1600x1200 @ 60, 70, 75, 85 Hz, 8, 16, and 32 bpp

Geode SC1200/SC1201/SC2200/SC3200 processors supported display modes:=20

- 1152x864 @ 75 Hz 8 bpp=20
- 1280x1024 @ 60, 75, 85 Hz, 8 bpp=20

Geode GX1 processors supported display modes:
- 640x480 @ 60, 72, 75, 85 Hz, 8 and 16 bpp
- 800x600 @ 56, 60, 72, 75, 85 Hz, 8 and 16 bpp
- 1024x768 @ 60, 70, 75, 85 Hz, 8 and 16 bpp
- 1152x864 @ 75 Hz 8, and 16 bpp
- 1280x1024 @ 60, 75, 85 Hz, 8 and 16 bpp

Geode SC1200/SC1201 processors supported TV modes (TV modes run only=20
on 16 bpp depth):
- NTSC-720X480
- NTSC-640X480
- PAL-768X576
- PAL-720X576=09

- Default mode is 640x480 16 bpp.

- To run 1280x1024@32 Video memory must be set to >=3D 8 MB in BIOS.

- To run 1600x1200@32 Video memory must be set to >=3D 9.37 5 MB in =
BIOS.

- Compression is disabled automatically if video memory is insufficient.
  (e.g. modes like 1280x1024@32 with 8 MB video memory).

- DDC (Display Data Channel) supported on the Geode GX1 processor-based =
platforms.
  - If Flat panel option is selected, then DDC option is ignored.


Dependencies
------------
Durango v2.51.02
Panel v1.3.5
DDC v1.1.1=20
tvoset v1.1.0


Functional Changes
------------------
- Readme.txt document modified with simple Build and Install =
instructions.
- Installation script has been added to install the Geode KFB driver =
sources.


Defects Corrected
-----------------
- #169.12 vfreq 56 Hz for mode 800x600 in not supported.


File Changes
------------
- All


Known Errata
------------
- Panning is not supported in the driver when flat panel is selected.

- Since flat panel display timings are different from the CRT,
  fbset utility shows different values for the vertical frequency=20
  when flat panel enabled.

- Panel support is not supported on the Geode SP1SC20/SP1SC21 platforms.
  If flat panel option is selected on SP1SC20/SP1SC21, display is =
distorted=20
  for BIOS version lower than v0.07.

expand it.
	"tar -zxvf linux-2.4.17.tar.gz"
- Then /usr/src/linux directory will be created.


Copying/injecting the Geode driver source into the existing kernel =
source tree
-------------------------------------------------------------------------=

Configuration changes to install the linux-2.4.17 kernel
--------------------------------------------------------

a) Update the file "/etc/lilo.conf":
	boot=3D/dev/hda
	map=3D/boot/map
	install=3D/boot/boot.b
	prompt
	timeout=3D50
	linear
	default=3Dlinux-2.4.17

	image=3D/boot/vmlinuz-2.4.17
			label=3Dlinux-2.4.17
			read-only
			root=3D/dev/hda1


b) Options for Geode KFB driver if it has been compiled as part of the =
kernel image=20
- Modify "/etc/lilo.conf" to use these kernel command line options:

  For example NTSC-720X480 TV mode option:
  ----------------------------------------

	boot=3D/dev/hda
	map=3D/boot/map
	install=3D/boot/boot.b
	prompt
	timeout=3D50
	linear
	default=3Dlinux-2.4.17

	image=3D/boot/vmlinuz-2.4.17
			append=3D"video=3Dnscfb:vmode:NTSC-720X480"
			label=3Dlinux-2.4.17
			read-only
			root=3D/dev/hda1

- Kernel command line options can be passed to nscfb with:
  `video=3Dnscfb:option1,option2:value2,option3' (multiple options =
should be=20
   separated by comma, values are separated from options by `:').=20

	Accepted options:
        -----------------
	The table for the Kernel mode numbers are:

	       |  640x480    800x600    1024x768   1280x1024    1600x1200

	24 bpp |  0x312/786  0x315/789  0x318/792 =20

	vesa:X	- Selects startup videomode. X is number from 0 to 0x1FF. See =
the=20
		  above table for detailed explanation.=20

	vmode:X	- Selects startup videomode. X is string of the format=20
		  widthxheight-depth.=20
=20
	vfreq:X	- Selects startup video vertical frequency. Takes 60, 70, 72, =
75=20
		  and 85 Hz. Default is 60 Hz.

	Linux_kernel_mode_number =3D VESA_mode_number + 0x200

	If adding in lilo.conf use the decimal number and not hex value.
	While using Geode frame buffer driver do not use "VGA=3DASK".
	To turn on the desired mode, use the video mode number of the Linux=20
	kernel which is the VESA mode number plus 0x200.

- Flat panel option is provided for TFT/DSTN support.
  This support is available only on platforms with CS9211 support.
        To select a Flat panel:

	1. Option "flatpanel:1".
		This option is used to select the flat panel.
               =20
	If BIOS supports flat panel the display will be flat panel and CRT.
	If BIOS does not support flat panel, the display defaults to CRT only.

     By default in the driver, flat panel is turned off for Geode GX1 =
and=20
     SC1200 processor-based platforms.

     This option is mandatory for Geode GX1 and SC1200 processor-based =
platforms
     to select flat panel support.  For flat panel based Geode GX (i.e., =

     GX 533@1.1W, GX 500@1.0W, GX 466@0.9W)processor platforms, default =
flat panel=20
     is enabled, so this is not required. In this version of driver, =
flat panel is=20
     supported on Geode GX (i.e., GX 533@1.1W, GX 500@1.0W, GX 466@0.9W) =
TFT=20
     version, Geode GX1 processor-based platforms, and the Geode SP4SC30 =
platform=20
     only.
=09
- Option Compression:=20
	- compression:1 is to enable the compression.
	- compression:0 is to disable the compression.
	- Default compression is enabled in the driver.

	sample options:
	---------------
		#append=3D"video=3Dnscfb:vmode:791"
		#append=3D"video=3Dnscfb:vmode:1024x768-16,vfreq:75"
		#append=3D"video=3Dnscfb:vmode:NTSC-640X480"

c) Execute the following commands:
	- Run "lilo"
	- Run reboot
