Remove generic 'fast trap' from the Xen public interfaces. Internally within Xen, we automatically set up direct trap for int 0x80, which is the only 'fast trap' vector that we ever supported anyway. Signed-off-by: Keir Fraser <keir@xensource.com>
Minimal OS
----------
This shows some of the stuff that any guest OS will have to set up.
This includes:
* installing a virtual exception table
* handling virtual exceptions
* handling asynchronous events
* enabling/disabling async events
* parsing start_info struct at start-of-day
* registering virtual interrupt handlers (for timer interrupts)
* a simple page and memory allocator
* minimal libc support
Stuff it doesn't show:
* modifying page tables
* network code
* block-device code
- to build it just type make.
- copy image.final somewhere where dom0 can access it
- in dom0
# xi_create 16000 test
<domid>
# xi_build <domid> image.final 0
# xi_start <domid>
this prints out a bunch of stuff and then every 1000 timer interrupts the
system time.
