Radeon HD 6670 Problems (no KMS, black screen)

AnarKEY · 05-27-2011, 09:44 AM

Hello,
I'm trying to get a brand new Radeon HD 6670 running, using kernel 2.6.39 (CONFIG_DRM_RADEON_KMS=y, CONFIG_DRM_RADEON=y) and gentoo.

First off a I tried to run it out of the box, but while booting the screen got black after:

Code:

Loading Turks MICROCODE
Refined TSC clocksource calibration: 2812.324 MHZ
Switching to clocksource tsc

After that, I booted with kernel parameter "nomodeset" to disable KMS. That worked, I got into the terminal und recompiled the kernel with CONFIG_EXTRA_FIRMWARE="radeon/TURKS_mc.bin radeon/TURKS_me.bin radeon/TURKS_pfp.bin" (after I installed x11-drivers/radeon-ucode - Package) and rebooted the machine with the new kernel (without kernel parameter "nomodeset"). Now I get no black screen, but the machine reboots after "switching to clocksource tsc" from above. Even worse.

Ok, now I decided to abandon to KMS, booted with "nomodeset"-Parameter and want to start the X-Server, but the xf86-driver-ati (
xorg.conf:

Code:

Driver "ati"

won't run without kms:

Code:

(EE) RADEON(0): Chipset: "TURKS" (ChipID = 0x6758) requires KMS

Then I try to configure X using the proprietary ati-driver (fglrx) with aticonfig, but there comes the next error:

Code:

PowerXpress error: Cannot stat '/usr/lib64/fglrx/switchlibGL': No such file or directory
Failed to initialize libglx for discrete GPU

Dispite this, I start X Server and wow, it works. But this is not that I really want, because I want to use the free "ati"-Driver with KMS.

Does anyone has a hint? Or any experiences with this card?

Many Thanx.

Did you also set CONFIG_EXTRA_FIRMWARE_DIR="/lib/firmware" in the kernel config?

Yes, CONFIG_EXTRA_FIRMWARE_DIR="/lib64/firmware" and /lib64 links to /lib

Well that's all I can really think of. Depending on the time of day, you might be able to find some of the developers on #radeon on irc.freenode.net.

This is linuxquestions.org. You are not likely to find much assistance with Windows problems.

Hi all,

i sadly seen the solution seems to be using another graphic card, or another OS.

So i post, even if late, my solution:
i have radeon HD6670 well working as KMS, almost with Kernel 3.1.6 and debian wheezy, and consequently well working opensource Xorg Gallium driver.

1) KMS must be enabled at kernel level.
2) 4 firmware files must be added in the kernel compilation and also in initramfs
- see Drivers->General driver options -> Include in-kernel firmware
and set "radeon/TURKS_me.bin radeon/TURKS_mc.bin radeon/TURKS_pfp.bin radeon/BTC_rlc.bin"
then also
(/lib/firmware/) Firmware blobs root directory

3) I don't use kdm/gdm graphic login stuffs at boot, i like to see the console end enter Xorg manually.
For my monitor, ACER2216W i used following GRUB config to have a nice text resolution.
KMS allows now a very responsive shell in the console boot.

# If you change this file, run 'update-grub' afterwards to update
# /boot/grub/grub.cfg.

GRUB_DEFAULT=0
GRUB_TIMEOUT=360
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet"
GRUB_CMDLINE_LINUX="vga=869 radeon.modeset=1"

# Uncomment to disable graphical terminal (grub-pc only)
#GRUB_TERMINAL=console

# The resolution used on graphical terminal
# note that you can use only modes which your graphic card supports via VBE
# you can see them in real GRUB with the command `vbeinfo'
GRUB_GFXMODE=1280x1024x16

# Uncomment if you don't want GRUB to pass "root=UUID=xxx" parameter to Linux
#GRUB_DISABLE_LINUX_UUID=true

# Uncomment to disable generation of recovery mode menu entrys
#GRUB_DISABLE_LINUX_RECOVERY="true"

4) compile kernel and install the .deb image, update-initramfs and update-grub
