GoKawiilLinux kernel patch fixes 2007-era AMD Radeon HD 2000/3000 video decode bug
A patch accepted for the upcoming Linux 7.5 kernel fixes a long-standing video corruption bug affecting AMD's RV610, RV620, RV630, RV635 and RV670 GPUs, used in the Radeon HD 2000 and HD 3000 series launched in 2007. The bug caused corrupted frames when the Unified Video Decoder read compressed video from system memory while the GPU simultaneously handled 3D or desktop rendering. First-time contributor Ted Bullock traced the issue to UVD buffers not being reliably pinned in VRAM and submitted a fix forcing them to stay there, as is already done for other chips.
