          Priority: medium
            Bug ID: 66064
          Assignee: dri-devel@lists.freedesktop.org
           Summary: ATI Mobility FireGL V5250 hardware incorrectly matched
                    with RV530 dri settings in r_300.dri
          Severity: normal
    Classification: Unclassified
                OS: Linux (All)
          Reporter: belfrancis2001@yahoo.ca
          Hardware: x86 (IA32)
            Status: NEW
           Version: XOrg 6.7.0
         Component: DRM/Radeon
           Product: DRI

Running Fedora 18 linux distribution with untainted kernel version 3.9.6-200 on
a Lenovo Thinkpad T60p with an ATI Mobility FireGL V5250 graphics card a video
information mismatch was discovered by running the following command:

$ LIB_GL=verbose glxinfo

The following lines in the output indicates a mismatch:

OpenGL vendor string: X.Org R300 Project
OpenGL renderer string: Gallium 0.4 on ATI RV530
OpenGL version string: 2.1 Mesa 9.2.0
OpenGL shading language version string: 1.20

... but the ATI Mobility FireGL V5250 graphics card has always been matched
with the RV350 graphics set.  This mismatch might be causing some video
glitches and visual artefacts from font rendering mistakes to malformed window
decorations.

In addition, if you run the following command:

$ dmesg | grep RV

you will get the following line:

[    1.793445] [drm] initializing kernel modesetting (RV530 0x1002:0x71D4
0x17AA:0x20A4).

Again should the modesetting be using RV350 specs in this case?

According to this:

http://www.notebookcheck.net/ATI-Mobility-FireGL-V5250.20382.0.html

It really is RV530. It's basically Mobility Radeon X1600 with slightly
different clock speeds. Closing.

Thank you for the clarification and the link to the "NotebookCheck" site for
further information.

After doing further research, it was still unclear whether a mismatch still
exists or not.  We can rule out using RV350; however, now it appears that RV535
might be a better candidate than RV530.  According to the ThinkWiki the
graphics chipset is identified as M66 and may be identified as M56GL.

See: http://www.thinkwiki.org/wiki/ATI_Mobility_FireGL_V5250

According to the Freedesktop Xorg DRI site the M66 graphics set is matched with
RV535.

See: http://dri.freedesktop.org/wiki/ATIRadeon/

Could someone check this out, please?

The "RV530" driver string isn't actually the name of your GPU, it's a category
that includes all RV53x GPUs, because the hw programming is the same for all of
those from a Mesa driver's point of view. Same for the kernel.

The driver is correct.
