9 * \brief Internal scheduler structures and definitions for processes.
13 * \author Bernardo Innocenti <bernie@develer.com>
18 * Revision 1.5 2004/08/14 19:37:57 rasky
19 * Merge da SC: macros.h, pool.h, BIT_CHANGE, nome dei processi, etc.
21 * Revision 1.4 2004/07/30 14:24:16 rasky
22 * Task switching con salvataggio perfetto stato di interrupt (SR)
23 * Kernel monitor per dump informazioni su stack dei processi
25 * Revision 1.3 2004/07/14 14:18:09 rasky
26 * Merge da SC: Rimosso timer dentro il task, che รจ uno spreco di memoria per troppi task
28 * Revision 1.2 2004/06/03 11:27:09 bernie
29 * Add dual-license information.
31 * Revision 1.1 2004/05/23 17:27:00 bernie
32 * Import kern/ subdirectory.
34 * Revision 1.3 2004/05/14 12:52:13 rasky
35 * Importato supporto kernel per AVR da Stefano
37 * Revision 1.2 2004/04/28 16:13:49 rasky
38 * proc_schedule() is now semi-private (used only within the kernel)
40 * Revision 1.1 2004/04/26 18:02:40 rasky
41 * Importato microkernel
43 * Revision 1.1 2004/04/04 17:40:26 aleph
44 * Add multithreading kernel
