As a reminder, this is a dmesg captured when running ATI Radeon HD 4670 AGP on a K10 host on Linux 5.9 (vanilla).
The ATI Radeon HD 4670 AGP (RV730 XT) is a very capable TeraScale GPU, supporting OpenGL 3.3 (Directx 10 on Windows) and OpenCL 1.0, and featured HDMI output and 1GB of VRAM. The host is also a very capable AMD Phenom II quad core CPU with 16GB of ram. To verify if its performances match 2020 expectations, I just engaged it (running Ubuntu 20.04) in 2020 Xonotic Defrag World Championship which is currently running (https://xdwc.teichisma.info/), and I got feedback from some players reporting this hardware may be better than their own hardware they compete with. In fact competitive games like Xonotic run at 144fps on 1920×1080 resolution. The last kernel able to drive this GPU on Ubuntu 20.04 LTS is the 5.4.0-47-generic one, the 5.4.0-48-generic one is believed to have backported the AGP disablement from 5.9-rc1 (ba806f9). So, when running on 5.4.0-48-generic kernel from Ubuntu repositories, or here, 5.9 vanilla compiled by myself, interesting parts from dmesg log may be: ``` [ 5.242322] [drm:r600_ring_test [radeon]] *ERROR* radeon: ring 0 test failed (scratch(0x8504)=0xCAFEDEAD) [ 5.242359] radeon 0000:01:00.0: disabling GPU acceleration ``` and: ``` [ 34.558889] trying to bind memory to uninitialized GART !
