           Summary: No DRM and DRI support for Trident-based chips
           Product: Drivers
           Version: 2.5
     KernelVersion: 2.6.x
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: enhancement
          Priority: P1
         Component: Video(DRI)
        AssignedTo: drivers_video-dri at kernel-bugs.osdl.org
        ReportedBy: adomail at gmail.com


Latest working kernel version: 2.4.x (supposedly)

Earliest failing kernel version: unknown (to me)

Distribution: all

Hardware Environment: All Video cards with Trident (or Trident-based, as VIA
PLE133) chips, tested in a Trident Cyberblade i1

Software Environment: Tested in Xubuntu (8.04), Ubuntu (6.10/7.04/7.10/8.04),
Mandriva (One 2008 Spring), openSUSE (10.3).

Problem Description: 

There is no DRM kernel module for Trident-based chips, so there is no specific
DRM support for those chips (mostly present in old laptops from Compaq -at
least Armada and Presario series-; Toshiba -at least some of the Portage and
Stellite series-; Hewlett-Packard -don't know the series, sorry-; probably many
others). 

If I'm not mistaken, having not DRM support implies having no DRI for those
chips, even if the trident_dri driver actually exists. I'm positive that the
Cyberblade series of the Trident Chips have no DRI support at all, and I've
tried to track the problem, which seems to reside in the absence of specific
DRM support for them.

Tried with last DRM and Mesa CVS via git, but no luck (in Madriva One 2008
Spring). Since the DRM support is a kernel module, I'm posting the issue here
as an enhancement, but it's actually not a problem, and nothing it's actually
failing.

In all the distros tested, the DRI module is succesfully loaded at X startup.
All the proper lines (as "Load "DRI"" or "Section "DRI"" with "Mode 0666" and
others) needed in Xorg.conf are present.

Steps to reproduce:

Simple get a box with a Trident card, install the distro of your choice, and
run glxinfo | grep direct to see that there's no direct rendering support. Look
at the drm kernel modelues, and no trident-specific module will be present.

Any extra information that I can provide, I will gladly try to.
If my post in this bugzilla is in the wrong place, please forgive me for
wasting your time.
Also, I apologize for my english, which is poor at best, I hope the report
isn't too confuse.
