General concepts

Red Hat Enterprise Linux 9.2 LPAR mode z/VM guest KVM guest

This information at an overview level describes concepts that apply across different device drivers and kernel features.

How devices are accessed by Linux
Applications on Linux access character and block devices through device nodes, and network devices through network interfaces.
Devices in sysfs
Most Linux device drivers create structures in sysfs. These structures hold information about individual devices and are also used to configure and control the devices.
Device auto-configuration for Linux in LPAR mode
As of z14 and LinuxONE II, you can store device configuration data for Linux in LPAR mode on the Support Element (SE).
Kernel and module parameters
Kernel and module parameters are used to configure the kernel and kernel modules.
