How-to guides¶
These guides walk you through key operations and processes of Real-time Ubuntu.
Get started with Real-time Ubuntu¶
Install the real-time kernel, and revert the change if needed. You can also run Real-time Ubuntu inside a KVM virtual machine for evaluation.
Measure system performance¶
Before tuning, establish a baseline latency measurement so you can quantify the effect of any changes you make to the real-time kernel.
Tune for real-time processing¶
These guides help you reduce and bound latency by isolating workloads, routing interrupts away from critical CPUs, and adjusting kernel boot parameters. More details of tunable parameters are available in Kernel boot parameters and Kernel configuration options.
Configure Real-time Ubuntu Core¶
For tuning an existing Ubuntu Core system, refer to Modify boot parameters on Ubuntu Core.
