Make sure you meet the following requirements: Linux-firmware – The operational functionality of various machine-connected devices is made possible via the firmware files availed by this package.Perf – This package makes it possible to monitor the performance of the Linux kernel via a perf tool.Kernel-tools – The kernel source’s supporting documentation and tools/directory are availed in this package.Kernel-headers – User-space programs and libraries are interfaced with the Linux system kernel through availed C header files.Kernel-devel – The sufficiency of kernel makefiles and headers provided by this package helps build against kernel packages, and system modules.Kernel – It is the main kernel package targeted for installation and caters to multi-core, multi-processor, and single-core systems.The installation of the Linux kernel on RHEL 8 will also highlight the following kernel-related packages: System Calls and Security – This kernel functionality ensures that service requests sent by processes are received.Device Drivers – Hardware and processes interaction need a kernel mediator/interpreter called device drivers.Memory Management – The location and exact usage of assigned system memory are monitored by the kernel.Process Management – The system kernel has an authoritative verdict on the time and duration of processes that should assign themselves to the CPU (Central Processing Unit).The main functions associated with the system kernel include the following:
Also, it is the kernel that provides an interfacing link between system processes and computer hardware. Since a Kernel is the primary bridge of communication between the hardware and software components of an entire computer system, it is responsible for such a system’s integrity and supported hardware compatibility. Each RHEL 8 distribution is shipped with a custom-built kernel.
Once you start/boot your machine, the Kernel takes control of the entire system. A Kernel is somewhat the soul of an operating system since it exists at its core.
