Sessions to host processes with special requirements
First Claim
1. A method for enabling a service executing in an isolated session on a system to access a system resource from which the service is isolated, comprising:
- instantiating a worker session by an operating system operating on the system, the worker session being a separate session from the isolated session and the worker session being a separate session from any user session executing on the system, instantiating the worker session including creating the worker session by a service executing in the isolated session by establishing a loopback remote presentation session connection to the system;
instantiating a worker process, the worker process executing in the worker session, the worker process having access to the system resource;
receiving by the service, a first communication indicative of a request from a first process to access the system resource;
sending, by the service, a second communication indicative of a request to the worker process to access the system resource;
in response to receiving, by the worker process, the second communication, accessing the system resource to produce a first result; and
transmitting, by the worker process, the first result to the service.

Abstract
Techniques are disclosed for enabling a system service executing in an isolated session to access system resources (such as a graphics processing unit) that it is isolated from. In an embodiment, the system service creates a “worker” session that is not isolated, and a “worker” process inside that worker session. Then, the system service is able to access the system resource that it is directly isolated from accessing by passing a request to the worker process to access the system resource on the system service'"'"'s behalf. The worker process does so, and passes a result to the system service.

10. A system for enabling a service executing in an isolated session on the system to access a system resource from which the service is isolated, comprising:
-
a processor; and a memory communicatively coupled to the processor, the memory bearing computer-executable instructions that, upon execution by the processor, cause at least; creating a worker session, the worker session being a separate session from the isolated session and the worker session being a separate session from any user session executing on the system, creating the worker session including creating the worker session by a service executing in the isolated session by establishing a loopback remote presentation session connection to the system; creating a worker process, the worker process executing in the worker session, the worker process having access to the system resource; sending, by the service, a request to the worker process to access the system resource; in response to receiving, by the worker process, the request to access the system resource, accessing the system resource to produce a result; and transmitting, by the worker process, the result to the service. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. A computer-readable memory bearing computer-executable instructions for enabling a service executing in an isolated session on a system to access a system resource from which the service is isolated, that when executed on a computer, cause the computer to perform operations comprising:
-
creating a worker session, the worker session being a separate session from the isolated session and the worker session being a separate session from any user session executing on the computer or another computer, creating the worker session including creating the worker session by a service executing in the isolated session by establishing a loopback remote presentation session connection to the system; creating a worker process, the worker process executing in the worker session, the worker process having access to a system resource; sending, by the service, a request to the worker process to access the system resource; in response to receiving, by the worker process, the request to access the system resource, accessing the system resource to produce a result; and transmitting, by the worker process, the result to the service.
