I used to have a working Radeon setup, but after I re-installed Gentoo I seem to get all kinds of problems. I'm trying to use this guide: http://wiki.gentoo.org/wiki/Radeon

Code:
# lspci | grep -i VGA
00:01.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Wrestler [Radeon HD 6310]

Hence I grabbed the line

"radeon/PALM_me.bin radeon/PALM_pfp.bin radeon/SUMO_rlc.bin radeon/SUMO_uvd.bin"

And pasted it into the indicated line in the kernel config. But this results in:


Code:
  MK_FW   firmware/radeon/PALM_me.bin.gen.S
make[1]: *** No rule to make target 'firmware/radeon/PALM_me.bin', needed by 'firmware/radeon/PALM_me.bin.gen.o'.  Stop.
Makefile:901: recipe for target 'firmware' failed
make: *** [firmware] Error 2


Also the "Enable modesetting on radeon by default" does not seem to exists anymore?

When I run xinit I get:

Code:
[    90.497] (II) [KMS] drm report modesetting isn't supported.
[    90.497] (EE) Screen 0 deleted because of no matching config section.
[    90.497] (II) UnloadModule: "radeon"
[    90.497] (EE) Device(s) detected, but none match those in the config file.
[    90.497] (EE)

Is this related to KMS, or is it that I need an xorg.conf file?

Code:
# gzip  -dc /proc/config.gz |grep KMS
CONFIG_DRM_KMS_HELPER=y
CONFIG_DRM_KMS_FB_HELPER=y

Creating a xorg.conf file does not seem to help.It will exit with the same error.

Seems like I missed the ./etc/firmware part. I'll see if it helps...

pgu,

A few things.

First, you will get a better response, if you edit your original post rather than reply to yourself. Replying to yourself drops you ot of the unanswered posts seach, so some potential helpers may never see your post.

Code:
[    90.497] (II) [KMS] drm report modesetting isn't supported.
suggests that you don't have radeon support in your kernel.

confirms it as that option is hidden until Radeon support is on in the kernel.

The problem was indeed the /lib/firmware location, hence the firmware was not loaded correctly. When I fixed that everything was working as described.

Check out:

http://wiki.gentoo.org/wiki/Xorg/Configuration
http://wiki.gentoo.org/wiki/Radeon <--- to see if you need REDWOOD or whatever

When configuring my kernel, I needed to pay particular attention to:

Device Drivers --->
Generic Driver Options -->
Include in-kernel firmware blobs in kernel binary
(radeon/REDWOOD_me.bin radeon/REDWOOD_pfp.bin radeon/REDWOOD_rlc.bin radeon/REDWOOD_smc.bin radeon/CYPRESS_uvd.bin)

(/lib64/firmware) Firmware blobs root directory

Without the above, the kernel wouldn't compile!

Hope this helps someone stumbling through (I wish I had found such explicit advice, it would have saved me time ;-)
