1 Minimal OS
2 ----------
4 This shows some of the stuff that any guest OS will have to set up.
6 This includes:
8 * installing a virtual exception table
9 * handling virtual exceptions
10 * handling asynchronous events
11 * enabling/disabling async events
12 * parsing start_info struct at start-of-day
13 * registering virtual interrupt handlers (for timer interrupts)
14 * a simple page and memory allocator
15 * minimal libc support
17 Stuff it doesn't show:
19 * modifying page tables
20 * network code
21 * block-device code
24 - to build it just type make.
26 - copy image.final somewhere where dom0 can access it
28 - in dom0
29 # xi_create 16000 test
30 <domid>
31 # xi_build <domid> image.final 0
32 # xi_start <domid>
34 this prints out a bunch of stuff and then every 1000 timer interrupts the
35 system time.
