23-Year-Old Radeon GPUs get a fix from the open-source Linux driver
Mesa just got a small but nice update for the R300g driver. Yes, you read that correctly, this architecture covers old ATI/AMD Radeon cards from the Radeon 9000 series up to R500 family (Radeon HD 2000). The patch was made by community contributor Pavel Ondračka, and it was merged this week.
The change adds pop-free clipping. In plain terms, when part of a triangle or line is still on screen but another part goes off screen, the driver should draw the part that is still visible. Some older paths could end up throwing away the whole shape once it crossed the screen boundary, which makes objects “pop” in and out when you move the camera.
If Linux 6.19 switching from the Radeon legacy to AMDGPU kernel drivers for the GCN 1.0/1.1 GPUs for those ~13 year old GPUs isn’t nostalgic enough for you, here’s something a bit more nostalgic this holiday season: fresh open-source driver commits to the Radeon R300g driver for supporting those 23 year old ATI R300 GPUs up through the 20 year old R500 class graphics processors.
