Framebuffer console on the Intel 810

Message

Kream · Post by **Kream** » Tue Feb 04, 2003 11:18 pm

I'm trying to enable the fbcon for the Intel 810. I've enabled
VESA VGA graphics console
Advanced low level driver options
<*> 8 bpp packed pixels support
<*> 16 bpp packed pixels support
<*> 24 bpp packed pixels support
x<*> 32 bpp packed pixels support
[*] Select compiled-in fonts
x x[*] VGA 8x8 font
x x[*] VGA 8x16 font

and in my /boot/grub/grub.conf I have
kernel /boot/bzImage root=/dev/hda6 vga=0x31A

on bootup, it says that this is not a recognised video mode. I can also not see anything in dmesg that indicates to me that the framebuffer device is operative.

how do I get this working / diagnose what went wrong ?

You didn't tell us which kernel version this is.

I have not had much success with i810 and Fb until 2.4.20-ck2.

Basically I just skipped using it. It doesn't add any value to my system anyway.

Also, the video mode you try to use, what is it (i.e 80x40, 130x50 or...)

using kernel 2.4.20-ck2

I just want to try it out... any help most appreciated.

i booted into various VGA modes when I put vga=ask .... you mean that's it ?

Yes, either that or a different video mode.

Check /usr/src/linux/Documentation/fb/vesafb.txt for different modes available.

Btw, that directory contains a lot of documentation on the use of Framebuffers in general.

This is what I appended.. ofcourse you should use your own sync and res values

Code: Select all

video=i810fb:vram=8:hsync1=31.5:hsync2=48.5:xres=1024:yres=768:mtrr:accel

Just thought I'd mention that you have to have a kernel patched with i810fb-lite or i810fb for the framebuffer on the Intel 810.

on my 2.6 kernel (gentoo-test-sources) , i use the cmdline "root=/dev/hda3 hdc=ide-scsi video=i810fb:vram:2,xres:1260,yres:1024,bpp:16,hsync1:30,hsync2:55,vsync1:50,vsync2:85,accel"

and:

i dont use the vesa driver, though ive found the same error w/ the vga= when i had practicallly all the fb options compiled in......no matter if i did 0x... or something like 791 it said it was a wrong number, and the ones it suggested were like 80x85 and such.....anyways, w/ the configuration i got above, fb works pretty good (but on the test11 preempt would cause directfb (and linux w/ it) to crash for some reason.........but ill test that on the final l8r)

My 2.6.x kernel does not do what I tell it to do.
fbset -xres, -yres, -g and other fbset command will return i/o control error.

I have not try 2.4.x yet.

vesafb let me do fbset -xres, though, that's all it will do.

boot arguement does nothing.[/quote]

zrl · Post by **zrl** » Fri Mar 19, 2004 8:03 am

kernel 2.6.x does have i810 framebuffer support.
see boot parameters in the linux/Documentation/fb/intel810.txt for detail.
the syntax from http://i810fb.sourceforge.net does not work. you have to do it as described in the kernel documentation.

hmm - it may be supported but I can't get it running

My grub line is:

kernel (hd0,0)/kernel-2.6.4-ck1 root=/dev/ram0 init=/linuxrc real_root=/dev/hda4 video=i810fb:xres:1280,yres:1024,bpp:32,accel,mtrr vga=795 splash=silent

but the astonishing thing is that he doesn't use i810fb at all!

vesafb: framebuffer at 0xf0000000, mapped to 0xf8800000, size 16384k
vesafb: mode is 1280x1024x32, linelength=5120, pages=5
vesafb: protected mode interface info at 00ff:44f0
vesafb: scrolling: redraw
vesafb: directcolor: size=8:8:8:8, shift=24:16:8:0
fb0: VESA VGA frame buffer device

I had to compile in vesafb as well otherwise the kernel would not compile at all

I tried the i810fb as a module and compiled in - no difference at all ...

Does the kernel 2.6.5-rc1-mm1 come with the most updated i810fb? I read the Documentation/fb/intel810.txt, and the date is Mar 17, 2002. So I guess it is the old one. i810b.sourceforge.net released a new one on Feb 1, 2003. And the author, Tony Daplas, didn't work on it for one year since he didn't have time.

News (16-01-2004):
I'm back. I've been busy for the most part of last year that I have neglected this project and even failed to answer most e-mails. One more thing, I don't have any access to any Intel 810 or 815 machines anymore, so it will be difficult to add features to the driver. However, I'll still try to do my best to submit patches/updates. Just let me know. (This time, I'll be around .

From the quote, since he doesn't have a i810 machine anymore, I think the development would be slowed down. Maybe you can give a try to the i810 from his site. But I don't know if that will apply to kernel 2.6 cleanly.

Hi guys,

I got my problem fixed

I
- compiled agpart, intel-agp and i810fb as modules
- put the following line in /etc/modules.autoload/kernel-2.6

i810fb

- put the following line in /etc/modules.d/aliases

options i810fb xres=1600 yres=1200 bpp=32 accel=1 mtrr=1

- do an

Code: Select all

modules-update

- put the following line in /boot/grub/grub.conf

kernel (hd0,0)/kernel-2.6.4-ck1 root=/dev/ram0 init=/linuxrc real_root=/dev/hda4 video=i810fb vga=838 splash=silent

and reboot ...

Et voila

Stefan

PS: On i810fb.sourceforge.net I saw only drivers for the 2.4 series so it seems that the 2.6 kernel has the most recent ones integrated ...

Does it work?

Painkiller · Post by **Painkiller** » Fri Oct 14, 2005 5:54 pm

Is this still Valid for the Kernel 2.6.12

I wanna run framebuffer with my Intel 810 chipset.

Also i found this document
http://i810fb.sourceforge.net/howto/index.html

But i don't wanna try until know about the dates.

i have i810fb working without any patches

i use gentoo-sources-2.6.11-r11

i have problems with 2.6.14-r2 i810fb seems to be broken in that release i have kernel panic upon boot

As I've said I am using gentoo-sources-2.6.11-r11

PS
I own i815 Mobo, but AFAIK it the asme Graphic Chip as in i810 (the same driver)
