There are a few of them in different places. I'm not sure which one it |
35 |
claims to need as none seems to match the name exactly. Here is a way |
36 |
to search tho. When you type in make menuconfig and it comes up, hit |
37 |
the / key. That would the the question mark WITHOUT pressing the shift |
38 |
key. Type in IOMMU and hit return. From there you can scroll though |
39 |
with the arrow keys to find out which one you think fits. |

This si my results: |

|
43 |
root@fireball /usr/src/linux-3.0.3-gentoo # cat .config | grep IOMMU |
44 |
CONFIG_GART_IOMMU=y |
45 |
# CONFIG_CALGARY_IOMMU is not set |
46 |
CONFIG_AMD_IOMMU=y |
47 |
# CONFIG_AMD_IOMMU_STATS is not set |
48 |
CONFIG_IOMMU_HELPER=y |
49 |
CONFIG_IOMMU_API=y |
50 |
# CONFIG_IOMMU_DEBUG is not set |
51 |
# CONFIG_IOMMU_STRESS is not set |
52 |

Yours looks the same as mine so not sure what to suggest other then the |
55 |
search above. Maybe you are Intel based where I am AMD based? |
