== 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.
