¶ CachyOS Kernel Manager
CachyOS provides a user-friendly application that makes it easy to install kernels from the repository and manage them.
The CachyOS Kernel Manager makes it simple to install kernels and also provides a comprehensive overview of all installed kernels.
¶ Installing a Kernel from the Repository
To install a kernel, simply launch the CachyOS Kernel Manager application and choose the desired kernel from a list of available options.
Then, simply click the "execute" button to complete the installation.
¶ Configuring and Building a Kernel
The CachyOS Kernel Manager also makes it easy to configure and build custom kernels. To get started, simply open the application and click the "configure" button. Then, you can adjust various settings, such as the scheduler, performance governor, tick rate, and more. Once you have made your desired changes, simply click the "execute" button to begin building your custom kernel.
Available configuration options include:
- Scheduler (BMQ, BORE, cacULE, cfs, PDS, TT)
- NUMA (disabled or enabled)
