    Courtesy of the complex routing and network configurations that Cloudflare uses, their engineers like to push the Linux network stack to its limits and ideally beyond. In a blog article [Chris Branch] details how they ran into limitations while expanding their use of soft-unicast functionality that fits with their extensive use of anycast to push as much redundancy onto the external network as possible.

  • Timur Kristóf ☛ Timur Kristóf: A love song for Linux gamers with old GPUs (EOY 2025)

    AMD GPUs are famous for working very well on Linux. However, what about the very first GCN GPUs? In this post, I’m going to summarize how well these old GPUs are supported and what I’ve been doing to improve that.

    This story is about the first two generations of GCN: GFX6 aka. GCN1 - Southern Islands (SI) and GFX7 aka. GCN2 - Sea Islands (CIK).

    Working on old GPUs

    While AMD GPUs generally have a good reputation on Linux, these old GCN graphics cards have been a sore spot for as long as I’ve been working on the driver stack.

    It occurred to me that resolving some of the long-standing issues on these old GPUs might be a great way to get me started on working on the amdgpu kernel driver and would help improve the default user experience of GNU/Linux users on these GPUs. I figured that it would give me a good base understanding, and later I could also start contributing code to newer GPUs.
