Abstract:
A marking capability is used to provide an indication of whether a block of memory is being used by a guest control program to back an address translation structure. The marking capability includes setting an indicator in one or more locations associated with the block of memory. In a further aspect, the marking capability includes a purging capability that limits the purging of translation look-aside buffers and other such structures based on the marking.
