Slackware-14.0 ATI driver question
Just a quick one here. I see Slackware-14.0 ships llvm. Is mesa compiled --with-llvm for older crappier half assed 2007 ATI cards like my RS600 (aka RS690, aka X1250 series, aka ???) which gains an improvement by getting llvm to replace it's vertex shader? Do I have to do anything special to set it up?

In June, llvm was not supporting indirect addressing

The new Mesa package is compiled with these following flags enabled:
Code:
./configure \ |
Ok i know it may not be related...
I have an ati radeon hd 6400 with two monitors and used the amd proprietary drivers with no issues... just finished the update and x didn't want to load fglrx now says no such device attached. I've notice the "radeon" module loads every time i started x.... anyways, last night i was too tired to deal with it so in order to load x i removed the fglrx driver and run xconfig. i downloaded the new drivers and installed them... but it run with erros and when checked the logs apparently the problem is related to the installer placing the module... please advice |
Of what update are you talking about? The one from 13.37 to 14.0? In this case, you'll need to rerun the amd installer as it needs to recompile the kernel module for the kernel found on 14.0. Make sure your kernel sources are there and properly configured (you should need to run "make mrproper" inside the kernel source directory).
Also note that when you install fglrx it overwrites libGL.so so, if you uninstall it, you'll need to reinstall the mesa package to make sure you have a libGL.so on your system. |
To deal with the various replies.
@Amani: That was R600g support - I have the older slower R300 for the stuff they're slightly ashamed they made. @ReaperX7: Spot on - that's what I needed. Thanks very much. @kernel-P4NIC: It's better to start your own thread on a different subject than hijack someone else's. |

You could be right. I haven't tested that, or haven't even figured how to test it.
I was told by developers on phoronix to set up with llvm as my card had basically no vertex shader. That was 15 - 18 months ago. It affects 2D performance, I think - certainly not 2D & 3D. I did get something going, but the results were inconclusive. |
Maybe they were referring to llvmpipe, a software-only driver which leverages LLVM for recompiling shaders stuff.
You can try it (don't know if Slackware 14.0 includes it or not) defining Code:
LIBGL_ALWAYS_SOFTWARE=1 Code:
GL_VERSION: 2.1 Mesa 9.1-devel |
ok i finally made mine to work.... however, the dumb question remains.
radeon (opensource) drivers are included in the xorg but i can't have desktop effects with radeon module loaded... apparently i need radeonhd (different set) how can i verify if these are also included? |

However, radeon in Xorg (contained in xf86-video-ati) != radeon in mesa != radeon in kernel. They are 3 completely different "drivers" with different purposes. I believe you still have something left behind by fglrx which is interfering with mesa (have you reinstalled mesa?), but the only way to be sure is to look at the X log file (/var/log/Xorg.0.log). radeonhd has been merged in mainline radeon drivers some eons ago and is now deprecated. |
@ kernel-P4NIC:
Radeonhd is dead a long time. Whatever you are reading is simply out of date. The current situation is that xf86-video-ati (giving a radeon driver) and the radeon kernel module are the open source offering. It should provide everything - desktop effects, etc. If you have a decent (or recently decent) ATI/AMD card, you can alternatively use the fglrx (kernel module & driver supplied) which may be faster. That binary blob accepts an uninstall argument (/uninstall or --uninstall, forget which). The handiest check to see if there's junk left about from fglrx is this ls -l /usr/lib(64)/libGL* Mesa libGL stuff is all 1.x (1.2, 1.3.x, 1.5.x). Fglrx uses very different numbers, and replaces these essential libs. Check what the symlinks are pointing at. |
Well guys
I appreciate your help... the card i have is a HD 3400 which support has been depreciated by amd with current drivers; however, they are offering support on previous version, so i installed that. Currently it is working. I'll remove the driver and make some test with the x86-video-ati to check which one is faster. and don't worry will create a new thread with the findings |
