Canonical has released its real-time Ubuntu 22.04 LTS Linux platform, intended to offer end-to-end security and reliability for time-bound workloads.
Unveiled February 14 and positioned for use in applications in telecom, aerospace, defense, and the public sector, Version 22.04 provides deterministic responses to real-time events and looks to minimize response time guarantees within a specified deadline. Based on Version 5.15 of the Linux kernel, Ubuntu 22.04 LTS integrates the out-of-tree PREEMPT_RT patch set for Arm and x86 architectures. This patch set reduces kernel latencies to ensure predictable task execution. Canonical said PREEMP_RT makes the kernel more preemptive than mainline Linux. Real-time Ubuntu is intended to offer performance, low latency, and security for telco infrastructure, with the kernel designed to meet telco transformation needs for 5G.
