* tools: Synchronize privcmd header constantsAndres Lagar-Cavilla2012-11-121-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | Since Linux's git commit ceb90fa0a8008059ecbbf9114cb89dc71a730bb6, the privcmd.h interface between Linux and libxc specifies two new constants, PRIVCMD_MMAPBATCH_MFN_ERROR and PRIVCMD_MMAPBATCH_PAGED_ERROR. These constants represent the error codes encoded in the top nibble of an mfn slot passed to the legacy MMAPBATCH ioctl. In particular, libxenctrl checks for the equivalent of the latter constant when dealing with paged out frames that might be the target of a foreign map. Previously, the relevant constant was defined in the domctl hypervisor interface header (XEN_DOMCTL_PFINFO_PAGEDTAB). Because this top-nibble encoding is a contract between the dom0 kernel and libxc, a domctl.h definition is misplaced. - Sync the privcmd.h header to that now available in upstream Linux - Update libxc appropriately - Remove the unnecessary constant in domctl.h Signed-off-by: Andres Lagar-Cavilla <andres@lagarcavilla.org> Acked-by: Ian Campbell <ian.campbelL@citrix.com> Committed-by: Ian Campbell <ian.campbell@citrix.com>

* libxc: add xc_gntshr_* functionsDaniel De Graaf2011-10-061-0/+82
| | | | | | | | | 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 Graaf2011-10-061-1/+32
| | | | | | | | | | | | | | | 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: NetBSD: implement xc_evtchn_bind_unbound_port.Ian Campbell2010-12-021-3/+0
| | | | | | | | | | | | | | | Doesn't actually appear to be used anywhere but is defined for other OSes. The NetBSD evtchn.h contains comments "Return allocated port" for several ioctls which currently return the allocated port as a member of the argument structure and not as the ioctl return value (I think this is a cut and paste error).

Copyright holders have been contacted by Stephen Spector and have all agreed this change. Removed tools/libxc/ia64/aclinux.h since it appeared to be unused. There is a separate, more up to date, copy in xen/include/acpi/platform/aclinux.h which does appear to be used. Clarify the license of MiniOS privcmd.h under the same terms as other tools/include/xen-sys headers.

* libxc: use new (replacement) mmap-batch ioctlKeir Fraser2010-01-131-0/+10
| | | | | | | | | | | | | | | | | | | | Replace all calls to xc_map_foreign_batch() where the caller doesn't look at the passed in array to check for errors by calls to xc_map_foreign_pages(). Replace all remaining calls by such to the newly introduced xc_map_foreign_bulk(). As a sideband modification (needed while writing the patch to ensure they're unused) eliminate unused parameters to uncanonicalize_pagetable() and xc_map_foreign_batch_single(). Also unmap live_p2m_frame_list earlier in map_and_save_p2m_table(), reducing the peak amount of virtual address space required. All supported OSes other than Linux continue to use the old ioctl for the time being. Also change libxc's MAJOR to 4.0 to reflect the API change. Signed-off-by: Jan Beulich <jbeulich@novell.com>
