It should work. But you need firmware that is not included in the |
| 10 |
kernel. You need to install the x11-drivers/radeon-ucode package, and |
| 11 |
then build a kernel that includes the appropriate firmware. Which |
| 12 |
firmware file (one of the *.bin files in /lib/firmware/radeon) is needed |
| 13 |
should be printed during boot; at the moment the kernel hangs, it should |
| 14 |
print which firmware file it was trying to load. |

On my HD4870, I configured it like so: |
| 17 |
|
| 18 |
In "Device Drivers -> Generic Driver Options", I've set: |
| 19 |
|
| 20 |
(radeon/R700_rlc.bin) External firmware blobs to build into the kernel |
| 21 |
binary |
| 22 |
(/lib/firmware) Firmware blobs root directory |
| 23 |
|
| 24 |
Then rebuild and install the kernel. Before you reboot, make sure you |
| 25 |
have built media-libs/mesa with the "gallium" USE flag set, and do an |
| 26 |
"eselect mesa set r600 gallium". Make sure you don't have disabled KMS |
| 27 |
in the kernel command line or module options ("radeon.modeset=0" |
| 28 |
disables KMS). After you reboot, you should have KMS + Gallium3D working. |
