Written by Michael Larabel in Arm on 3 October 2025 at 09:47 AM EDT. 1 Comment
In addition to the Arm and RISC-V SoC changes and new platforms/machines added for the Linux 6.18 kernel, the separate Device Tree pull request was merged for this next kernel version that also now adds the strings for the upcoming Arm C1 Nano, Pro, Premium, and Ultra processor cores.

Last month Arm announced the Lumex CSS Plaform with the C1 CPUs. The Arm C1 Nano / Pro / Premium / Ultra branding will eventually replace Cortex-A and Cortex-X branding moving forward.
