Hi, |
2 |
|
3 |
my PC consists -- beside other things -- of a AMD Phenom II X6 1090T, |
4 |
a ASUS Crossfire Formula IV and a NVidia GeForce GT 430 by MSI (PCIe). |
5 |
Furthermore I am using the vanilla Linux kernel 3.0.1. . |
6 |
|
7 |
I browsed through the output of dmesg and found these lines: |
8 |
|
9 |
Checking aperture... |
10 |
No AGP bridge found |
11 |
Node 0: aperture @ c4000000 size 32 MB |
12 |
Aperture pointing to e820 RAM. Ignoring. |
13 |
Your BIOS doesn't leave a aperture memory hole |
14 |
Please enable the IOMMU option in the BIOS setup |
15 |
This costs you 64 MB of RAM |
16 |
Mapping aperture over 65536 KB of RAM @ c4000000 |
17 |
|
18 |
The kernel is not configured with any AGP-related (as far as I now) |
19 |
feature/config. |
20 |
|
21 |
Why does it look for an AGP-bridge??? |
22 |
|
23 |
The dmesg says I should switch on IOMMU, which I did. But that does |
24 |
not impress the kernel that much since it still recommends to switch |
25 |
on IOMMU. |
26 |
|
27 |
What did I wrong here ? |
28 |
|
29 |
I want to fix issues, which may be reported by dmesg, so: |
30 |
Where can I find explanations to the dmesg output? |
31 |
|
32 |
For your information I attached the compressed dmesg output |
33 |
to this mail. |
34 |
|
35 |
Thank you very much for your help in advance! |
36 |
Best regards |
