AMD Radeon HD 4770 and Open Source Drivers

Just thought I would get this out there. As of right now for these drivers to be loaded in Debian one should install the firmware-linux-nonfree package.

Haven't had much time with this to provide feedback on these drivers. I thought it would help in identifying my native resolution, but that was of no luck. Here are some Google fu keywords that would indicate you are missing this package.

dmesg will output
r600_cp: Failed to load firmware "radeon/RV730_pfp.bin"

glxinfo (part of mesa-utils) will say something like
OpenGL vendor string: VMware, Inc.
OpenGL renderer string: Gallium 0.4 on llvmpipe (LLVM 0x300)

After installing this package the result is no dmesg and this for glxinfo
OpenGL vendor string: X.Org
OpenGL renderer string: Gallium 0.4 on AMD RV740

Hope that helps I'll probably make a post if I get my resolution corrected. Or there is already nice instruction:


And some glxgear timings:
279 frames in 5.0 seconds = 55.705 FPS
260 frames in 5.1 seconds = 51.439 FPS
280 frames in 5.0 seconds = 55.854 FPS
274 frames in 5.0 seconds = 54.704 FPS
