Abstract:
A server logical partition (LPAR) of a virtualized computer includes shared memory regions (SMRs). The SMRs include pages of the server LPAR memory to share with client LPARs. A hypervisor utilizes an export vector to associate logical pages of the server LPAR with SMRs. The hypervisor further utilizes a reference array to associate SMRs with client LPARs that have mapped at least one physical memory page of the SMR from a logical page of the client LPAR memory. In processing an operation to unmap one or more shared physical pages from one or more LPARs, the hypervisor uses the export vector and reference array to determine which LPARs have had a mapping to the physical pages.

Claim (Index 1):
A method for managing a shared memory mapping in a computer, the method comprising:\n receiving a first shared page request, wherein the first shared page request is associated with a first logical page included in a first logical memory block (LMB) of a first logical partition (LPAR), wherein the first logical page corresponds to a physical page included in a shared memory region (SMR) associated with the first LPAR; determining, in response to the first shared page request, based at least in part on the first logical page corresponding to the physical page, a shared access state associated with the first LMB, wherein the shared access state indicates that the SMR is associated with first LMB; receiving a second shared page request, wherein the second shared page request is associated with access to the physical page by a second LPAR included in the computer; determining, in response to the second shared page request, a mapping state associated with the SMR; receiving a mapping request associated with the physical page; determining, in response to the mapping request, based at least in part on the shared access state associated with the first LMB and the mapping state associated with the SMR, that the second LPAR has established a mapping to the physical page; and invalidating the mapping to the physical page established by the second LPAR.
