DYNAMIC STORAGE KEY ASSIGNMENT
First Claim
1. A computer implemented method for a dynamic storage key assignment, the method comprising:
- receiving, by a host bridge, a request;
determining, by the host bridge, that a dynamic storage key assignment is supported and enabled in association with a memory address space referenced by the request based on a requester identifier or a portion of a peripheral component interconnect address associated with the request; and
based on determining that the dynamic storage key assignment is supported and enabled, accessing, by the host bridge, a page included in the memory address space based on a storage key included in the request matching a storage key associated with the page being accessed or an entry in a listing of permitted storage keys for the memory address space.
