e0a112bc2a remove obsolete check for APIC support 2012-07-22 13:13:46 +02:00
Stefan Lankes
24914fcb4f add prototype of a tickless kernel 
only by entering the kernel, the tick counter will be updated
=> by using this feature, MetalSVM supports only LwIP's raw interface,
   because we have no guarantee that the tcpip thread will get computation time
=> no NETCONN & BSD socket support
=> no load balancing support

c6339bfd2d by leaving the interrupt handler, we check if an urgent task is ready 
if yes, the kernel switchs to this task

dfe2c817de Continued the small documentation journey. 
Edited Doxyfile - will show static functions and vars now, because some
of them were interesting for documentation.

45219bce2e - huge commit 
- enable the paging support
- redesign of the APIC code

TODO:
- Currently, we are not able to start user-level applications.
- The RTL8139 driver does not longer work. Perhaps, a bug in the output function.
- The APIC codes doesn't work on all systems. Therefore, the code is currently disabled.
