* libxc: introduce xc_domain_get_guest_width()Dario Faggioli2013-09-131-5/+3
| | | | | | | | | | | | | | 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.

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: eliminate static variables, use xentoollog; API changeKeir Fraser2010-05-281-6/+6
| | | | | | | | | | | | | | | | | | | | 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 foreign address translation bugKeir Fraser2008-05-021-1/+1
| | | | | | | | | In the xc_translate_foreign_address function from libxc, there is a check on the page directory entry to see if the page is 4K or 4M. However, the check is looking at bit 3, when it should be looking at bit 7. This patch fixes the problem. Signed-off-by: Bryan D. Payne <bryan@thepaynes.cc>
