Context Navigation

source: soft/giet_vm/giet_kernel/irq_handler.c @ 720

Last change on this file since 720 was 709, checked in by alain, 9 years ago

Major release: Change the task model to implement the POSIX threads API.

The shell "exec" and "kill" commands can be used to activate/de-activate the applications.
The "pause", "resume", and "context" commands can be used to stop, restart, a single thtead or to display the thread context.

This version has been tested on the following multi-threaded applications,
that have been modified to use the POSIX threads:

classif
convol
transpose
gameoflife
raycast
