System, Apparatus And Method For Filtering Memory Access Logging In A Processor

At least one computer readable storage medium comprising instructions that when executed enable a system to:

• responsive to a first access to a page of a memory, determine whether a first indicator of a page table entry associated with the page has been set and whether a process value stored in a filter storage matches a current process value;
• and
• responsive to a determination that the first indicator has been set and that the process value matches the current process value, write an address of the page to a first entry of a first storage to indicate that the first access to the page occurred.

A system comprising:

• a processor including a first register to store a process value for a process for which page modification logging is to be enabled, and a page modification logger to write an entry into a page modification log when a modification access to a page of a memory is performed in an active process, responsive to a determination that an identifier of the active process corresponds to the process value stored in the first register;
• and
• the memory coupled to the processor, wherein the memory is to store at least a portion of the page modification log.
