When recently carrying out performance benchmarks of Intel Meteor Lake performance on Linux since launch day two years ago, the geo mean came in at 93% the original performance. Finding the performance trending clearly lower with an up-to-date Linux software stack compared to in December 2023 was quite surprising considering the rather nice gains we have seen over time on other Intel/AMD hardware. As noted in that article though, one of the possible explanations there is the Spectre BHI "Branch History Injection" vulnerability and microcode plus Linux kernel mitigations having come out post-launch and affecting Meteor Lake CPUs. Sure enough, follow-up tests looking at the Spectre BHI impact have revealed a measurable cost in a number of workloads for the Core Ultra processor.

As part of the "tools", the main motivator for this documentation has been around the era of AI and large language models with coding assistants and more. Torvalds made some remarks on the Linux kernel mailing list around his belief in focusing the documentation on "tools" rather than explicitly focusing on AI, given the likelihood of AI-assisted contributions continuing regardless of documentation.

8 January 06:25 AM EST - Intel - dGPU Firmware Updating On Non-x86

The modern Intel Xe kernel graphics driver was designed from the start to be more broadly compatible with non-x86 architectures given their discrete graphics processors being front and center, unlike the legacy i915 kernel graphics driver being very x86 minded. While this allows running Intel Arc Graphics on ARM or RISC-V, there are some other kinks still being ironed out with using Intel graphics in the non-x86 world. One of those limitations currently being worked through is the lack of GPU firmware updating on non-x86 systems.

Sent out today was the latest batch of drm-misc-next changes to DRM-Next for staging ahead of the upcoming Linux 6.20~7.0 kernel cycle.
