Source: mesa Version: 18.3.6-2+deb10u1 Tags: patch Hi all,
10th generation Intel Comet Lake GPUs are a refresh of the 9th generation. Linux Kernel >= 5.2 supports these GPUs, which means the kernel for buster- backports will allow one to run buster on relatively new hardware. DRI, vsync and other acceleration is somewhat broken however, as the support in Mesa was only added in 19.1. But because it is a refresh the actual GPUs are practically the same and only their PCI IDs have to be added. Please consider backporting the attached simple patch adding the PCI IDs to buster's Mesa version. This avoids the need of a complex backport to a new major version of mesa and gives users of Comet Lake hardware a fully operational GPU with buster. I have tested this patch myself on a laptop with an i5-10210U and after the IDs are added the GPU works perfectly, including vsync etc, when also using the kernel from buster-backports. For more background information refer to: https://www.phoronix.com/scan.php?page=news_item&px=Mesa-19.1-Has-Comet-Lake Cheers, Melvin.
