* mini-os: Make utility function get_self_id() in fs-front.c public.Keir Fraser2008-12-161-0/+11

* stubdom: use host's gccKeir Fraser2008-07-041-21/+32
| | | | | | | | This makes stubdom use the host's gcc instead of downloading/compiling binutils+gcc. That requires a bunch of changes and even uncovered a few bugs, but saves a lot of time. Signed-off-by: Samuel Thibault <samuel.thibault@eu.citrix.com>

* minios: avoid putting trailing \0 in xenstoreKeir Fraser2008-03-181-1/+1
| | | | | | | xenstore expects to get the exact amount of data, without the trailing \0. Signed-off-by: Samuel Thibault <samuel.thibault@eu.citrix.com>
* minios: Fix lost eventsKeir Fraser2008-03-181-0/+1
| | | | | | | | | | | | | | | evtchn_bind_interdomain used to clear any already pending event before binding a handler, because else the handler may be called before it is ready. That however leads to missed events, which I had to workaround for the HVM case. This changes the semantics of bind_evtchn, and thus of all the event channel binding functions (bind_virq, evtchn_alloc_unbound, evtchn_bind_interdomain) into not unmasking the event itself, hence letting the caller initialize properly before unmasking the port (e.g. record the port number in an appropriate place).
