The kernel is manually compiled from gentoo hardened-sources-3.11.3 with |
| 32 |
PAX and GRSEC enabled for desktop system, RBAC disabled. (The system |
| 33 |
runs stable packages with the kernel being one of very few exceptions.) |
| 34 |
|
| 35 |
In the "Graphics support" section just two things are enabled manually, |
| 36 |
the rest is automatically selected: |
| 37 |
|
| 38 |
CONFIG_DRM and CONFIG_DRM_RADEON. |
| 39 |
|
| 40 |
This results in the following (unset options shortened): |
