           Summary: The new MESA degrades performance on RS690M and x1270
                    graphs chip.
           Product: Mesa
           Version: 7.5
          Platform: All
        OS/Version: Linux (All)
            Status: NEW
          Severity: major
          Priority: medium
         Component: Drivers/DRI/R600
        AssignedTo: dri-devel@lists.sourceforge.net
        ReportedBy: de.techno@gmail.com


I don't exactly remember but I think the 6th version of mesa used to draw ~500
FPS in glxgears. With mesa 7.5, it's ~350 and 7.7 it has dropped to less than
200. Same for the latest development version of mesa (i'm using Gentoo and the
latest development version is the one provided by the live ebuilds in the x11
overlay).

The direct render is in general very slow on this chip; 500 FPS is very less
considering the performance of this chip.

Moving to DRI/R300 since the 690/X12xx uses a 4xx-series 3D core and so runs
the r300 driver, not r600.

Development work has shifted from the "classic" r300 HW driver to the "R300g"
Gallium3D-based driver - probably would be good to start testing that on your
systems. The 300g driver includes an improved SW TCL implementation (using
LLVM) and should generally be faster on your systems.

Where can I get this? r300g or 300g doesn't yield any search results in

With x11 overlay, something like the below?

emerge eselect-mesa

eselect mesa list

Now you should see r300 classic and gallium, and be able to switch between
them:

eselect mesa set r300 gallium
eselect mesa set r300 classic

You also need a recent version of mesa with gallium use flag.

But from your initial description it looks like you already have that use flag:
media-libs/mesa
    Installed versions:  9999 (..) (gallium (..))

No, actually I removed that after finding no difference, but I never used
eselect to actually use the classic or gallium drivers.

Right now, I can't enable the gallium USE flag (it's surrounded by () and I
don't know what it means).

Ok, I somehow compiled with gallium support, but the module mesa is missing in
eselect.

Any more ways to use r300?

I guess you have to build Mesa from source (git) to get r300g.

Actually it's more of a kernel issue.

If I use the Gentoo kernel on Sabayon, the frame rates reduce to a fraction.
Corresponding opposite results.

That ATI chip got burnt out, and nobody else's complaining.

Performance of this card (and driver too) could be better.

Recomended configuration under Gentoo:
USE="gallium -classic llvm"
VIDEO_CARDS="radeon r300"

llvm can give you in some applications/games double framerate, so please use
it.

And reminding, that glxgears isn't benchmark. Bigger value better, but doesnt
measure real performance.

This is 3 years old bug, so closing as WONTFIX, if someone step up to improve
performance, as owner of RS690, i'll be glad :)
