Abstract
A method for identifying relocatable kernel memory allocations in kernel non-relocatable memory is described. In this method, a physical address hardware mapping entry (PA HME) for each process accessing a physical page of memory by physical addresses. For each of the PA HMEs corresponding a process that does not permit page relocation, the pre-relocation handler and post-relocation handler references of each PA HME is set to null. Each PA HMEs is associated with a pmapping list for the physical page. Thus, A physical page is identified as non-relocatable when one of the PA HMEs referenced by the pmapping list has null pre-relocation and post-relocation handler references.
