* Fix emacs local variable block to use correct C style variable.David Vrabel2013-02-211-1/+1
| | | | | | | The emacs variable to set the C style from a local variable block is c-file-style, not c-set-style. Signed-off-by: David Vrabel <david.vrabel@citrix.com
* libxc: add xc_gntshr_* functionsDaniel De Graaf2011-10-061-0/+10
| | | | | | | | | These functions and the xc_gntshr device (/dev/xen/gntalloc on linux) allow applications to create pages shared with other domains.

* libxc: add xc_gnttab_map_grant_ref_notifyDaniel De Graaf2011-10-061-14/+6
| | | | | | | | | | | | | | | Normally, when a userspace process mapping a grant crashes, the domain providing the reference receives no indication that its peer has crashed, possibly leading to unexpected freezes or timeouts. This function provides a notification of the unmap by signalling an event channel and/or clearing a specific byte in the page. This also unifies the 3 very similar grant-mapping osdep interfaces into a single function instead of introducing yet another minor variation.

* libxc: osdep: convert hypercall buffer allocationIan Campbell2011-03-111-0/+3
| | | | | | | This will allow us to use OS specific interfaces to ensure that the allocated memory is safe for use as a hypercall buffer in the future. Signed-off-by: Ian Campbell <ian.campbell@citrix.com>
* libxc: add abitility to dynamically load osdep.Ian Campbell2010-12-031-0/+15
| | | | | | | | Add a dummy backend which always returns ENOSYS. Mainly as a compile time testbed rather than because it is a useful backend. Signed-off-by: Ian Campbell <ian.campbell@citrix.com> Signed-off-by: Ian Jackson <ian.jackson.citrix.com>

* libxc: add ability to query OS interface for "fakeness"Ian Campbell2010-12-031-0/+3
| | | | | | | | | | | | i.e. not running on a real hypervisor Allows users of the library to adjust behaviour. I don't especially like this violation of the abstraction but both oxenstored and xapi use this to avoid difficult to simulate operations when running on the simulator.
