Operations interlock under dynamic relocation of storage

摘要

A multi-boundary address protection range is provided to prevent key operations from interfering with a data move performed by a dynamic memory relocation (DMR) move operation. Any key operation address that is within the move boundary address range gets rejected back to the hypervisor. Further, logic exists across a set of parallel slices to synchronize the DMR move operation as it crosses a protected boundary address range.

1. A method for interlocking operations under dynamic memory relocation in an address-sliced cache system, comprising:
initializing a dynamic memory relocation (DMR) move operation in a plurality of parallel slices of the address-sliced cache system; generating a relocatable storage segment address range and an associated function for the DMR move operation; partitioning the relocatable storage segment into a contiguous series of boundary address ranges; creating a DMR reject mechanism that operates on a designated slice of the plurality of parallel slices; comparing a first key address of a first key operation with a move address of the DMR move operation; and responsive to the first key address being outside of a first boundary address range of the contiguous series of boundary address ranges, performing the DMR move operation while interlocking the first key operation; wherein: the DMR move operation operates within the first boundary address range in the plurality of parallel slices.
