Link with libxenctrl, #include <xenctrl.h> and use one of xc_map_foreign_{range,pages,bulk}(). You can find examples of their use throughout the tools/ directory in xen-unstable.hg repository. -- Keir > greets, > david > > _______________________________________________ > Xen-devel mailing list > Xen-devel@lists.xensource.com > http://lists.xensource.com/xen-devel ^ permalink raw reply [flat|nested] 3+ messages in thread

Do you have any idea why? Do you know where I can find a good documentation about memory mgmt in xen? greets david > >> >> -- Keir >> >>> greets, >>> david >>> >>> _______________________________________________ >>> Xen-devel mailing list >>> Xen-devel@lists.xensource.com >>> http://lists.xensource.com/xen-devel >> >> >> > ^ permalink raw reply [flat|nested] 3+ messages in thread
