* minios: add xenbus_read_uuidMatthew Fioravante2012-11-131-0/+4
| | | | | | | | | Similar to xenbus_read_integer, this function reads a xenstore path and parses it as a uuid. See include/xenbus.h for details.

* mini-os: make frontends and xenbus optionalDaniel De Graaf2012-02-091-0/+12
| | | | | | | | | | | | | | | | | This adds compile-time logic to disable certain frontends in mini-os: - pcifront is disabled by default, enabled for ioemu - blkfront, netfront, fbfront, kbdfront, consfront are enabled by default - xenbus is required for any frontend, and is enabled by default If all frontends and xenbus are disabled, mini-os will run without needing to communicate with xenstore, making it suitable to run the xenstore daemon. The console frontend is not required for the initial console, only consoles opened via openpt or ptmx.

* Xenbus implementation ported from Linux to Mini-os, simple thread support ↵kaf24@firebug.cl.cam.ac.uk2005-09-091-0/+89
introduced to simplify the porting. 64 bit version of Mini-os now compiles, but does not work because of the pagetables and some bits of scheduler not being written. Signed-off-by: Grzegorz Milos <gm281@cam.ac.uk>
