Ubuntu maker Canonical today announced the general availability of an enterprise-grade real-time Ubuntu kernel for Ubuntu 22.04 LTS systems to provide enterprises with end-to-end security and reliability for their time-bound workloads.

Designed for enterprises in aerospace, automotive, defense, IoT, robotics, and telcos, as well as the public sector and retail, the real-time Ubuntu kernel promises to handle the most demanding and critical workloads, or time-sensitive applications by reducing kernel latencies and boosting performance.

Canonical announces real-time Ubuntu kernel

> As a real-time solution, it was designed to minimize the response time guarantee within a specified deadline. With a new enterprise-grade real-time kernel, Ubuntu 22.04 LTS can keep up with stringent low-latency requirements such as smart factory applications.

Canonical debuts Real-time Ubuntu for low-latency applications

> The newly developed real-time kernel within Ubuntu is better able to serve extreme latency-dependent use cases, providing deterministic response times to service events, Canonical said. In this way, it can minimize response time guarantees within a specified deadline, making it ideal for time-sensitive applications in the automotive, aerospace, industrial, public sector, retail and telecommunications sectors.

Real-time Ubuntu is now generally available

> “The real-time Ubuntu kernel delivers industrial-grade performance and resilience for software-defined manufacturing, monitoring and operational tech”, said Mark Shuttleworth, CEO at Canonical. “Ubuntu is now the world’s best silicon-optimised AIOT platform on NVIDIA, Intel, MediaTek, and AMD-Xilinx silicon”.

Canonical Announce Availability of Real-Time Ubuntu

> Ubuntu’s real-time kernel is based on the Linux 5.15 LTS kernel offered in Ubuntu 22.04 LTS, and is available for both x86 and Arm architectures. Canonical note that the Real-time Ubuntu kernel integrates out-of-tree PREEMPT_RT patches to reduce kernel latencies, making it ‘more preemptive’ than mainline Linux kernels.

Real-time Ubuntu Linux now available

> 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.

Canonical announces the general availability of Real-Time Ubuntu Linux 22.04 LTS

> Most of you know Ubuntu as a desktop operating system; others know it as an outstanding server Linux; or as a popular cloud OS. But Canonical, Ubuntu's parent company, is also a serious Internet of Things (IoT) player. And after years of work, IoT release, Ubuntu Core 22.04, Canonical is offering a true real-time operating system.

> A real-time operating system is one that's fast enough that it can guarantee a reaction to data within a tight, real-world deadline. Typically, real-time computing delivers results from microseconds (one-millionth of a second) to milliseconds (one-thousandth of a second). Real-time applications that take things down to microsecond latency include stock market high-frequency trading (HFT) applications. The much more common millisecond real-time processing is used in banking and telecom applications, digital ad networks, and self-driving cars. Us? People? We have average reaction times of around 250 milliseconds.

What you need to know about the real-time capable edition of Ubuntu 22.04

> The new real-time edition was announced on Valentine's Day [insert joke about loving a more responsive computer here]. The beta version appeared last year, a couple of months after the launch of 22.04 "Jammy Jellyfish" that April. The difference from standard Ubuntu is that this version integrates the out-of-tree PREEMPT_RT patches into kernel 5.15.
