With the newly-released Linux 6.16 kernel there is the new X86_NATIVE_CPU build option if wanting to optimize your kernel build for your local CPU in use. Enabling CONFIG_X86_NATIVE_CPU is setting the "-march=native" compiler optimizations for the kernel build in an effort to ensure peak performance/optimizations for the local system. Here are some benchmarks looking at the impact of X86_NATIVE_CPU on Linux 6.16 while using the HP ZBook Ultra G1a laptop with AMD Strix Halo SoC as an interesting test target for squeezing additional performance.
Last year Canonical established a policy to always ship the latest Linux kernel version at Ubuntu release time which for the upcoming Ubuntu 25.10 will mean shipping with Linux v6.17. But during the Ubuntu development cycles they typically don't aggressively update to new interim versions tracking upstream, except that will now change to allow for better kernel test coverage...
While the Broadcom V3D driver has been part of the mainline kernel for supporting the graphics found on recent Raspberry Pi boards, currently it doesn't support run-time power management. The lack of runtime PM has meant the GPU clock remains at full-speed even while idle...
Intel's accelerator efforts in recent generations of Xeon processors have been challenging to say the least. From limited software support and configuration obstacles to some current-generation accelerators not being safe for VM use due to security issues to having to deal with higher latency and other nuances if wanting to achieve decent performance. One of the Linux kernel users of Intel's QuickAssist Technology "QAT" accelerators has been the FSCRYPT code for native file encryption support. But the Linux kernel with the FSCRYPT usage is now demoting the Intel QAT accelerator support along with other problem-causing accelerator drivers...
The open-source, reverse-engineered Rockchip NPU driver "Rocket" developed by Tomeu Vizoso will soon be in the mainline kernel. The Rocket Gallium3D driver was also merged today for Mesa 25.3 in the user-space code for their AI accelerator support...
Among the number of early pull requests submitted in advance for the Linux 6.17 merge window were all the power management updates as well as to related areas like ACPI and thermal control drivers...
