 Posted: Tue Sep 14, 2004 9:35 pm Post subject: i830 HOW-TO (on Gateway 200X) |
 |
|
After quite a bit of wrestling with this "broken" laptop i have managed to get everything working including the i830 internal video chipset. The Gateway 200X does not allow the video memory to be set through the bios and ironically the bios function used to set this is not available.
There are 3 steps to get this "beast" of a video card working:
1) Get the latest driver and compile it into the kernel.
Get it here -> http://www.skynet.ie/~airlied/patches/dri/i915_linux.diff
tested with 2.6.8.1-ck6
patch -p0 < path/to/i915_linux.diff
| Code: |
Kernel config
[Processor type and features]
[*] MTRR (Memory Type Range Register) support
[Device Drivers]
<*>/dev/agpgart (AGP support)
<*> your chipset
[*] Direct Rendering Manager
<*> Intel 830M,845G,852GM,855GM,865G,915G (new) |
compile (make install modules modules_install), copy bzImage to /boot/bzImage, and reboot.
2) Fix the memory allocation
*This will work for any computer no matter which card or mobo.
run dmesg (in bash) and look for:
| Code: | agpgart:.....
mtrr: 0x(A), 0x(B) overlaps existing.... |
where A and B are some hex values.
now type cat /proc/mtrr, you should get something like this:
| Code: | reg00: base=0x0000000 ( 0MB), size = 512: write-back, count=1
reg01: ....
reg02: base =0xA (3712MB), size= 4MB: write-combining, count = 2 |
take note of the reg number where base = 0xA (address that is causing problems) and create a new text file: /etc/conf.d/mtrr-fix.
| Code: | #!/bin/bash
echo "disable=2" >| /proc/mtrr
echo "base=0xA size=0x4000000 type=write-combining" > /proc/mtrr |
this will create a 64 MB space at the problematic location, thus solving our problems.
now make sure that mtrr-fix has the right permission and that it starts upon boot
| Code: | conf.d # chmod 777 mtrr-fix
local.start:
/etc/conf.d/mtrr-fix
|
reboot and continue on to step 3
3) The last step is to get our xorg.conf up-to-date
Here is mine:
| Code: |
Section "Module"
Load "dri"
Load "glx"
Subsection "extmod"
Option "omit xfree-dga"
EndSubSection
EndSection
Section "Device"
Identifier "Card0"
Driver "i810"
ChipSet "852GM/855GM"
Card "i830"
BusID "PCI:0:2:0"
EndSection
Section "DRI"
mode 0666
EndSection
|
There you go, i830 is a go now and everyone is super happy.

I have no overlap in my mtrr.
Moreover, I can not use the 2.6 kernel, as they do not support my USB ADSL modem. Therefore I must stick to my 2.4.25 kernel.
This is the output of my dmesg:

If you can change your AGP apareture size in your bios then do so and decrease it to 64 megs, I am saying this because it fails when it tries to load tv-out. You only have 204 free megs so it could be due to this. If not report back.
EDIT: if this does not solve your problem then you will probably have to compile agpgart and intel_agp and i830 as modules and use the mtrr-fix to set the memory to 64 megs and load the modules.

It did not help.
This is what I got now on dmesg:
| Code: |

Well i have one question, at the beginning did your memory card reside on reg 2. It may be that in fact it is not on reg2. can you do cat /proc/mtrr and post the output here. Maybe i didn't make it clear but in your mtrr-fix file
echo "disable=(number)" should be set to the reg number, In my case it was 2.

| Code: |
reg00: base=0x0ff00000 ( 255MB), size= 1MB: uncachable, count=1
reg01: base=0x00000000 ( 0MB), size= 256MB: write-back, count=1
reg02: base=0xf0000000 (3840MB), size= 64MB: write-combining, count=1
|
It seems to me that my memory resides on reg01, as 256M is the amount of RAM that I have.
I will try that now. |

I tried it, and the system became horribly slow, even without X.
I don't think that mtrr is the problem, as the log of X claims that the problem is assigning an irq to the drm module.
Thank you for trying to help, anyway.[/code] |
