* libxc: introduce xc_domain_get_guest_width()Dario Faggioli2013-09-131-17/+4
| | | | | | | | | | | | | | As a wrapper to XEN_DOMCTL_get_address_size, and use it wherever the call was being issued directly via do_domctl(), saving quite some line of code. Actually, the function returns the guest width in bytes, rather than directly what XEN_DOMCTL_get_address_size provides (which is a number of bits), since that is what it is useful almost everywhere.

* libxc: pass an xc_interface handle to page locking functionsIan Campbell2010-10-181-2/+2
| | | | | | | | | Not actually used here but useful to confirm that a handle is passed down to each location where it will be required once we switch to hypercall buffers. Signed-off-by: Ian Campbell <ian.campbell@citrix.com> Signed-off-by: Ian Jackson <ian.jackson@eu.citrix.com>

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: remove \n from strings passed to PERRORKeir Fraser2010-05-281-1/+1
| | | | | | | | Previously, the code was inconsistent: some calls to PERROR passed \n and some did not. With the new logging arrangements, passing \n is definitely incorrect. Signed-off-by: Ian Jackson <Ian.Jackson@eu.citrix.com>
* libxc: eliminate static variables, use xentoollog; API changeKeir Fraser2010-05-281-27/+27
| | | | | | | | | | | | | | | | | | | | This patch eliminate the global variables in libxenctrl (used for logging and error reporting). Instead the information which was in the global variables is now in a new xc_interface* opaque structure, which xc_interface open returns instead of the raw file descriptor; furthermore, logging is done via xentoollog. There are three new parameters to xc_interface_open to control the logging, but existing callers can just pass "0" for all three to get the old behaviour. All libxc callers have been adjusted accordingly. Also update QEMU_TAG for corresponding qemu change. Signed-off-by: Ian Jackson <ian.jackson@eu.citrix.com>
* libxc: use new (replacement) mmap-batch ioctlKeir Fraser2010-01-131-2/+2
| | | | | | | | | | | | | | | | | | | | 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>
