Abstract:
A marking capability is used to provide an indication of whether a block of memory is backing an address translation structure of a control program being managed by a virtual machine manager. By providing the marking, the virtual machine manager may check the indication prior to making paging decisions. With this information, a hint may be provided to the hardware to be used in decisions relating to purging associated address translation structures, such as translation look-aside buffer (TLB) entries.
