The newest Arm SoC seeing Linux kernel patches working their way toward the mainline kernel is the Axiado AX3000 as a security processor designed for cloud data center, network gear, and more.

The Axiado AX3000 series is a Trusted Control/Compute Unit (TCU) aimed to fend off cyberattacks by leveraging AI for preemptive threat detection and a range of other capabilities. The latest Linux patches were posted yesterday for enabling this SoC in the Linux kernel along with its evaluation/reference board.

The [1]Linux patch series explains of this Axiado AX3000 SoC support:

"This patch series adds initial support for the Axiado AX3000 SoC and its evaluation board.

The AX3000 is a multi-core system-on-chip featuring four ARM Cortex-A53 cores, secure vault, hardware firewall, and AI acceleration engines. This initial support enables basic bring-up of the SoC and evaluation platform with CPU, timer, UART, and I3C functionality."

In May Axiado announced the AX3080 as their newest hardware security solution while this patch series out this week is just for the AX3000 non-AX3080 model. These patches are under review as Axiado works to get support for this TCU upstreamed into the mainline Linux kernel.
