AMD/ATI fglrx 8.961 Catalyst 12.4 (build 5) rpms available for openSUSE 12.2, 12.1, 11.4, 11.3 & Tumbleweed

May 31st, 2012 by

Those informations are obsolete now : please consult //lizards.opensuse.org/?p=8888

AMD/ATI Catalyst 12.4 / fglrx 8.961 (build 5 revised) rpms are available

Quick Résumé about 12.4

The first version available in repository from April 30th has trouble with any kernel never than 3.3

Sebastian Siebert has create a patch for kernel 3.4+, I google translate quickly his blog article here.

AMD catalyst control center and fgl_glxgears

May 30th 2012
WARNING! Who use AMD Catalyst 12.4 driver from the AMD installer will inevitably have problems with kernel 3.4.0 and higher (eg from the Tumbleweed repo).
Because the driver is designed, at least up to kernel 3.3.x on openSUSE only.
Here are some examples of errors when compiling a kernel module fglrx:

error: 'cpu_possible_map' undeclared (first use in this function) ... 
error: implicit declaration of function '__save_init_fpu'

Or when you load the fglrx kernel module:

 A FATAL: Error inserting fglrx (/ lib/modules/3.4.0-25-desktop/extra/fglrx.ko): Unknown symbol in module, or unknown parameter (see dmesg)
 The output of dmesg: fglrx: Unknown symbol old_rsp (err 0) 

I now have an updated makerpm-amd script and replaced the older packaging from script to a newer.
At this point, I say thank you for the helpful feedback and also to the AMD community that their minds have assembled to investigate the problem and make it to the world.
The packaging script I maintain, need no extra time. The kernel patches for the compiler error I’ve already entered for this month in the AMD installer. In the next AMD Catalyst we will not need this patch anymore. Since the patch will be included in the source fglrx from AMD for the next version.

Small warning for stormy times: AMD plans to graphics chips R6xx/R7xx not lead to the main branch.
The graphics card series Radeon HD 2000, 3000 and 4000 are affected (Phoronix has reported). The last supported version is expected to be AMD Catalyst 12.7. However, AMD has turned in and stored in a separate branch of this, it weiterzupflegen there. It means that no new feature added, but only fix bugs. openSUSE 11.4 and 12.1 is still supported and maintained. The chances are good that the driver to get there will also run on an X-Server 1.12.
The next openSUSE version 12.2 in July, will should use the X-server 1.10, so that the driver theoretically run on this version of openSUSE. For this I’ll create a separate makerpm-amd script, that this legacy continues as usual drivers to install on openSUSE 11.4 and 12.1 (possibly 12.2) and will also provide the necessary kernel patches. AMD believes that these chipsets will already extensive support from the free Radeon driver. So it is time to order a new graphics card in order to continue the beta drivers from AMD Catalyst testing on openSUSE. A new graphics card was already planned last October. So I will finally keep your hardware donation for the new graphics card.

See more at Sebastian’s blog.
Don’t be shy, you can leave there the result of test in english too :D
or ask in forums, irc and ping freespacer.
See below what to do in case of troubles.

The rpms version 8.961 are available from Thursday May 31

Ruby: Why to use symbols as Hash keys ( and why not )

May 24th, 2012 by

I have often read that for hash keys it is better to use symbols than strings. So I was interested why and what is performance impact. It is quite easy to create a test scenario to measure it. The blog post also contains technical explanation and shows potential security problem. (more…)

A New Font Repository

May 21st, 2012 by

what do you need when you write some text? Content, of course. Apart from your content you need an additional part to make it a shiny contribution: fonts! If you don’t know already: we have now a new repository dedicated just to fonts.

openSUSE in Education, Spreading Continue

May 17th, 2012 by

What do you feel as an open source developer, user, or enthusiast if you see this beautiful piece of software is used by hundred of schools and thousand of students? Great isn’t it? And that’s what happened here in a small dot on this earth in Yogyakarta Indonesia.

This program was initiated by the Government of Indonesia with the objective to introduce the open source and e-learning method to student and teacher. So three years ago I was contacted to help them to realize their dream, and here I’m now reporting that there are around 7300 openSUSE installation in 350 elementary and junior-high schools. We also use SLES in servers to provide repositories and e-learning materials in SCORM using Moodle.  This is work in progress. We educate teachers to use openSUSE and also creating learning material so it is always in beta stage I think :D

I want to say thank you to all the good people, my friends and co-workers, they are unknown in openSUSE community, even many of them are not subscribing the mailing list, but they are the true openSUSE ambassadors in Indonesia. They come to schools and persuade the teachers to use openSUSE. Without them this dream will never come true. Picture below show some of them smiling holding the openSUSE 12.1 promo DVD that AJ sent to me. You all great! Also picture of teachers while following our session about openSUSE.

All the good people
