Benchmarks Of AMD's Newest Gallium3D Driver

[89c51]

Its about 100 developers working full time.

Dave.

i expected that to be honest


thanks for the answer and the codes mr Airlie


but...
isn't there any ways to attract more developers in that area ie. an fsf/linux foundation campaign, or try to raise more money (for paying devs) from the industry, or propose some Thesis on Universities on the subject or whatever

Did you consider that radeon drivers have vsync and vblank on by default limiting the maximum framerates which leads into a lower average?

omh again no information about color tiling and pageflipping...
im using color tiling and get much better framerates...
what a bad article...

PTS automatically sets vblank_mode to 0.

Why X1000 was not included as base reference?

They're not all mainline yet... FTA: "The Gallium3D driver performance will also improve once the latest color tiling and page-flipping patches have been merged, which should happen soon. Another article is planned at this time looking at the Radeon page-flipping performance as it may bring sizable performance boosts."

FTA: "Unfortunately since AMD dropped support for the R500 hardware and earlier back in 2009 with a Catalyst driver release that is no longer compatible with today's Linux distributions and hardware, we are unable to compare the relative performance directly of the R300g driver + Catalyst to that of today's combination."

The article says clearly:

Are you sure that this is enough?

AFAIK, you need to patch the driver manually to disable vsync.

Thanks for the benchmark.

Updating some packages to latest rawhide on Fedora 14 works quite nice to test Gallium3D.

su -c 'yum update --enablerepo=rawhide kernel libdrm mesa-* xorg-x11-drv-ati cairo pixman'
