Kernel
The Kernel is a program that is the core of IPLOG-GAMA's operating system, with complete control over everything in the system. It is one of the first programs loaded upon start-up (after the bootloader). It handles the rest of start-up as well as input/output requests from the software, translating them into data-processing instructions for the central processing unit. It handles memory and all hardware peripherals.
A kernel connects the application software to the hardware of a IPLOG-GAMA unit. The critical code of the Kernel is loaded into a separate area of memory, which is protected from access by application programs or other, less critical parts of the operating system. The kernel performs its tasks, such as running processes, managing hardware devices, and handling interrupts, in this protected kernel space. In contrast, everything a user does is in user space: writing text in a text editor, running programs, packages, scripts etc. This separation prevents user data and Kernel data from interfering with each other and causing instability and slowness, as well as preventing malfunctioning application programs from crashing the entire operating system.
Embedded Linux
Embedded Linux is composed of the:
- Kernel - Core of an operating system.
- Shell - A User interface for access to an operating system's services via Command-line (BASH interpreter).
- Packages - programs for the operating system. A list of available default packages.
From Kernel,Shell and Packages is compiled Linux operating system image for IPLOG-GAMA units.
Linux available versions: 4.4.26-linux4sam_5.5
