upgrading libdrm

User0x45 · 02-03-2009, 09:45 PM

I'm having problems getting my box with a VIA mobo and an ATI r200 video adapter
to use DRI.

Some folks at the ATI forum and the DRM maintainers have had me post this as a
bug.http://bugs.freedesktop.org/show_bug.cgi?id=19698

The latest suggestion regarding debugging this is to:

Quote:

you could try making libdrm and using it instead of the system one

I don't quite understand. I think I am being asked to take my current (SL12.2)
provided libdrm, and upgrade it to the latest.

My Slack 12.2 has a package: libdrm-2.3.0-i485-1 which installs
/usr/lib/libdrm.so.2.3.0

and also a README that simply says:

Code:

By default, this will install into /usr/local.  If you want to install this
libdrm to replace your system copy, say:

./configure --prefix=/usr --exec-prefix=/

The latest libdrm is libdrm 2.4.4 http://lists.freedesktop.org/archive...ry/000746.html

So, I need to do a git download of the latest libdrm, do a make, and install it.
This all sounds daunting, and filled with a chances to really screw it up.

Is there a command to identify which drm modules, which libdrm is currently up and
running on my running system?

lsmod? modinfo? something?

Once I feel confident that I can observe and identify what I have on my system, that will
give me confidence so when I install the newer versions I can run the command and verify
that I have done the libdrm upgrade successfully.

1) how do I confirm what is currently on my system (libdrm, drm).
2) how do I upgrade to the latest libdrm
3) how do I confirm that the latest is properly installed.

Thanks.

I think I've run into this problem twice before. As I recall, it has something to do with the different DRM implementations (Kernel, X.org and ATi each seem to have one... :/ ). Looking at my own setup, disabling CONFIG_DRM in .config and installing X.org's libdrm lets things work in relative harmony. Sorry if you've tried that already, but I figure it doesn't hurt to share tips anyway.

Are there multiple instances of DRM on a working system. If so, when running startx how do I designate
a specific one. And, with X up and running what command can I run to show which DRM implementation is
being used. (Or, in my case, not being used.)

FWIW,

Here is some of the relevant original DRI error in my Xorg log.

There is a DRI wiki. It has a page

1. Building the DRI with X.org and Mesa
1.3. Building libdrm

http://dri.freedesktop.org/wiki/Buil...c082e830832250

So I am going to backup my /usr/lib/libdrm*
and then dive in building a git pull from the source.

I fear I am going to horribly break everything. But, oh well.

if you are going to upgrade those you can easily modify the slackbuilds included inthe source of 12.2. I have upgraded them to use the opensource driver 3d rendering. Get the latest mesa and see which libdrm it suggests. Build the libdrm first then build the mesa driver. upgradepkg should do the trick. Good luck and I really can't see things really being broken too much(atleast not easily fixed).

I'd hate to say, but the latest DRI probably won't work right unless you upgrade to Xserver 1.5.

User0x45 · 02-05-2009, 01:12 AM

I've been told that the latest libdrm is backwards compatible with the last x server and mesa.
(I'm just the messenger on that bit of info.)

I think I am going to build mesa and libdrm, back up my libs, that swap in libdrm.so.2.4.4.

Will it work, will it fail?

The other option is to teach myself how to make a slackbuild for this source.

I searched slackbuilds for 'dri', 'drm', 'mesa' and nothing.

What, and where is the slackbuild that is used for the official slackware libdrm package?

Is there a repository of Patrick V. official slackware slackbuilds somewhere?

Go here:

Choose your nearest mirror, and look in the /12.2/source/x/libdrm directory.
