STORAGE DEVICE ACCESS USING UNPRIVILEGED SOFTWARE CODE

摘要

The subject disclosure is directed towards establishing more direct access to a storage device from unprivileged code. Using a storage infrastructure mechanism to discover and enumerate storage architecture component(s), a user mode application requests at least one portion of the storage device to store application-related data. The storage infrastructure mechanism determines whether the application is authorized to access the storage device and if satisfied, the storage infrastructure mechanism configures at least one path for performing block-level input/output between the storage device and an unprivileged storage architecture component.

主权项

1. A computing device, comprising:
at least one processing unit; and system memory hardware communicatively coupled to the at least one processing unit and including components comprising:
a storage infrastructure mechanism, executing on the at least one processing unit, to map at least one portion of the computing device to substantially match an address space associated with application-related data that corresponds to executing input/output activity, the application-related data being stored in the system memory hardware, and configuring at least one path between the at least one portion of the computing device and an unprivileged storage architecture component for executing the input/output activity using the address space.
