Summary: KMS with X1950 XT i2c error --> no ddc Product: DRI Version: unspecified Platform: All OS/Version: All Status: NEW Severity: critical Priority: medium Component: DRM/Radeon AssignedTo: dri-devel@lists.freedesktop.org ReportedBy: revealed@freakmail.de
Hello!
This is the operating system and kernel:
cat /etc/SuSE-release openSUSE 11.4 (i586) VERSION = 11.4 CODENAME = Celadon
uname -rio 2.6.37.1-1.2-desktop i386 GNU/Linux
When trying to boot with Kernelmodesetting there is no DDC due to an i2c error resulting in a blank screen.
I was told in irc channel #radeon to open a bugreport and attache vbios.rom and dmesg of a boot with KMS enabled;
I hope you can help me out!
Many thanks for all your Help!
Greetings,
R

--- Comment #4 from Alex Deucher agd5f@yahoo.com 2011-04-14 09:44:35 PDT --- Does booting with: i2c-algo-bit.bit_test=0 on the kernel command line in grub fix the issue?

Yes :D

The default value for i2c-algo-bit.bit_test is 0. For some reason Suse sets it to 1. You can manually adjust it by editing the i2c_algo_bit entry in the files in /etc/modprobe.d/

--- Comment #7 from revealed revealed@freakmail.de 2011-04-14 10:48:28 PDT --- Ha!
So the problem seems to have existed due to my TV-Card:
cd /etc/modprobe.d/ disk@wild-thing:/etc/modprobe.d> grep i2c * 50-blacklist.conf:blacklist i2c-matroxfb 50-tv.conf:options i2c-algo-bit bit_test=1
Man!! :D I thank you so much! I dont know why this is enabled in 50-tv.conf; I have a Hauppauge PVR 150. I dont know if this has to be enabled for it. But it is...

--- Comment #8 from revealed revealed@freakmail.de 2011-04-14 10:58:39 PDT --- Sorry for doubleposting:
I added the option to menu.lst; As workaround. Thank you for the hint!
Also i tried commenting out the option in 50-tv.conf; And i removed the newly added bootparameter for a test.
The issue came back in this constellation. So the value seems to be set as default.
Possible requirement for my TV-Card?
I can live with adding this as bootparameter to menu.lst
Many Thanks!

odd. maybe your distro changed the default in their kernel source.
Possible requirement for my TV-Card?
No. It's a debugging option for i2c. You could potentially run into the same issue with another driver that uses i2c bit algo.

Leave it open for now. They might have some ideas why i2c-algo-bit.bit_test=1 is set by default.

you can ignore it or remove this line in i2c_bit_prepare_bus(): struct i2c_algo_bit_data *bit_adap = adap->algo_data;

Or they can set i2c-algo-bit.bit_test=0 in the interim.
