Linux Soft Real-Time Target v2.4

28 Sep 2004 (Updated 28 Aug 2008)

Custom Linux target for Real-time Workshop.

File Information
Description	The Linux Soft Real-Time Target is a target definition to Real-Time Workshop from Mathworks. The target uses the POSIX real-time clocks to generate periodic signals, to wake the model process at every time step. The process is changed to real-time highest priority defined by the scheduler, and therefore needs root privileges to execute. The Linux Soft Real-Time Target does not run hard real-time, since the kernel of Linux itself is not preempted by the scheduler. As a consequence, model execution can occasionally be delayed. A standard Linux kernel preempts every 10 ms. Higher resolution of the task switching, and thereby precision of the model execution, can be achieved by setting HZ to a different value in asm/param.h, included in the kernel source, and re-compiling the kernel. To include C S-Functions from other directories place the rtwmakecfg.m file included in this package in the directory of the C S-Function source file. The C S-Function must be mex'ed in order for Simulink to pass the path to Real-Time Workshop.
Required Products	Real-Time Workshop Simulink
MATLAB release	MATLAB 7.3 (R2006b)
Other requirements	Linux platform.

Updates
02 Dec 2005	Support for R14 SP3
02 Dec 2005	Support for R14 SP3
30 Oct 2006	Re-installation of default signal handler was observed causing exit of real-time code. The handler is now installed after each execution. The RTW parameters now supports linker options mainly for comedi support. There is a post-compilation command.
18 Jan 2007	Added support for cross-architecture code generation.
27 Feb 2007	Updated files, as something went wrong with previous update.
26 Mar 2007	Added support for including C S-Functions from other directories.
12 Aug 2008	Added detection of sample overrun. The Alarm Clock exit is not substituted with a deadline violation notification, and continued exectution. Added "[LNX]" to all model outputs to separate from other debug info from e.g. S-Functions.
28 Aug 2008	Title mismatch.
