Abstract

Systems and methods are described herein to provide for secure host resource management on a computing device. Other embodiments include apparatus and system for management of one or more host device drivers from an isolated execution environment. Further embodiments include methods for querying and receiving event data from manageable resources on a host device. Further embodiments include data structures for the reporting of event data from one or more host device drivers to one or more capability modules.

Claims

1. A non-transitory machine-readable medium having machine executable instructions contained therein, which when executed perform the following operations:

receiving event management data from a host device driver;

determining if the event management data exceeds a threshold; and

sending the event management data to at least one capability module if the event exceeds a threshold value related to the event management data previously received from the capability module, where the at least one capability module is executed within an environment isolated from the host device driver.

2. The machine-readable medium of claim 1, wherein the event management data includes an event resource data record related to an event on a host device.

3. The machine-readable medium of claim 1, wherein the threshold is set by the at least one capability module prior to receiving the event management data from the host device driver.

4. The machine-readable medium of claim 1, wherein the host device driver is to communicate over a direct memory access channel.

5. The machine-readable medium of claim 1, wherein the host device driver is a ring 3 software application.

6. The machine-readable medium of claim 1, wherein the host device driver is to communicate with a mailbox interface module communicatively coupled to the at least one capability module through a management core.

7. The machine-readable medium of claim 1, wherein the host device driver is a ring 0 software application.
