    Phoronix: ATI R300 Gallium3D Driver Seeing A Big Performance Fix After Being Regressed For Years

    For those still running decade and a half old ATI Radeon graphics hardware like the Radeon Xpress 200M found in numerous notebooks back in the day, a performance regression in the R300 Gallium3D driver is being sorted out after concerned users on this vintage hardware began bisecting and testing patches for a regression to this old ATI open-source driver that appears to have been adversely affected back in 2017...

    And the noise…! Dear God, the noise…! 😶

    True. But in this case you have to worry about issues Mac-flashed cards (originally being PC-BIOS) can have.

On some card<->machine combinations the GPU locks up and resets when reaching the desktop. In this case you can use the kernel boot parameter "radeon.agpmode=-1" as workaround.
    Great! I have a X1950 XT (flashed) ready to install on my Power Mac G5 (just waiting for the power cable to arrive), so it's nice to know KMS is working. Fortunately my G5 is all PCIe, so I don't have to worry about buggy AGP bridges.

    Wow, does that mean South Korea has finally ditched all the ActiveX websites?

    Good news.
    Improving the drivers also for older hardware makes Linux a real all-rounder.

    phoronix (Michael) , have you already covered the following two Linux top stories?

    2) The Russian Army is saying Goodbye to Windows and moving to their secure Linux named "Astra Linux" which is based on Debian and runs on many platforms including ARM. 3 June 2019.

    We'll be waiting for extensive benchmarks with PTS.
