Linux Kernel State Tracer

Table Of Contents:

Description
[This section describes the technology ....]

LKST is Kernel State Tracer for Linux in order to keep track of Kernel Event such as: - Process Management - Interrupt - Exceptions - System Calls - Memory Managements - Networking: sending packets, receiving packets - Sys V IPC - Locks - Timer - Oops

Originally LKST is developed for Linux Enterprise Systems and now we have port it to Reference Boards for Embedded Systems and currently SH4 port(RTS7751R2D), MIPS/TX49 port (RBHMA4400CE) and ARM/OMAP port (TI OMAP INNOVATOR/OSK) are available.

Rationale
LKST is one of a number of tracing systems available for the Linux kernel. Such event tracing systems are very useful for analyzing kernel behaviour, and learning how interrupts, kernel threads and user-space applications interact on the system.
