* 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/+27
| | | | | | | | | 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 Graaf2011-10-061-6/+20
| | | | | | | | | | | | | | | 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: Remove set_max_grants in linuxDaniel De Graaf2011-01-171-0/+2
| | | | | | | | | The maximum number of grants is now constrained domain-wide in linux, so set_max_grants should be a noop there. Previously, this constraint was per-file-description. Signed-off-by: Daniel De Graaf <dgdegra@tycho.nsa.gov> Committed-by: Ian Jackson <ian.jackson@eu.citrix.com>

* libxc: some xc_gnttab_* functions are not Linux specificIan Campbell2010-12-231-0/+147
| | | | | | | | | They simply make hypercalls and perform other operations via the abstract interface. Create xc_gnttab.c and move those functions there.

* Make it possible to run valgrind on code linked with the libxc libraries.emellor@leeni.uk.xensource.com2005-11-221-1/+1
| | | | | | | | | | | | | | Valgrind cannot see when a hypercall has initialised entries in a data structure, so appropriate memsets have been placed before using dom0_op_t, privcmd_hypercall_t, and a couple of miscellaneous blocks passed into this layer. This initialises the block so that valgrind considers it to be valid, but the data therein will be immediately overwritten by the hypercall, all being well. These changes are semantically neutral if -DVALGRIND is not set. Signed-off-by: Ewan Mellor <ewan@xensource.com>

* Get rid of memory_t. Almost all uses should be unsigned long.kaf24@firebug.cl.cam.ac.uk2005-08-191-5/+5
| | | | | | | | | | | | The few uses for a physical/machine address have been mostly changed to u64. Grant table code probably needs auditing for PAE correctness, but at least the interface is now sound. Signed-off-by: Keir Fraser <keir@xensource.com>
* Remove unnecessary union in grant table map/unmap ops.akw27@arcadians.cl.cam.ac.uk2005-08-131-2/+2
| | | | | | | All addresses, host virtual and PTEs, are now passed in the cunningly ambiguous "host_addr" field, rather than in an anonymous union.
