Execution manager for binary objects operating across private address spaces
Techniques are disclosed to operate binary objects across private address spaces. In various embodiments, a private shared memory segment is allocated for two non-privileged address spaces, the first comprising a home address space and the second comprising a target address space. One or more executable modules are loaded in a private address space of the home address space. One or more program call routines and an environment to schedule system request blocks (SRB) are built in the home address space. The environment to schedule system request blocks is configured to be used to schedule an SRB into the target address space, the SRB comprising information configured to cause the target address space to cause an associated one of the executable modules to execute.
1. A system, comprising:
a memory; and
a processor coupled to the memory and configured to:
allocate a shared memory segment of the memory for two non-privileged address spaces, the first comprising a home address space and the second comprising a target address space;
load one or more executable modules in a private address space of the home address space; and
build in the home address space one or more program call routines and an environment to schedule system request blocks;
wherein the environment to schedule system request blocks is configured to be used to schedule an SRB into the target address space, the SRB comprising information configured to cause the target address space to cause an associated one of the executable modules to execute.
2. The system of claim 1 , wherein the processor is further configured to identify a task control block (TCB) associated with the target address space.
3. The system of claim 1 , wherein the target address space is configured to execute the executable module from the shared memory segment.
4. The system of claim 3 , wherein the target address space uses an asynchronous exit routine to execute the executable module.
5. The system of claim 4 , wherein an SRB unit of the target address space resumes upon completion of the executable module.
6. The system of claim 4 , wherein a cross-memory post is sent by the target address space to the home address to signal completion of the executable module.
7. The system of claim 1 , wherein the executable module comprises a function.
8. The system of claim 1 , wherein the executable module provides shared access to a file or other stored object.
9. The system of claim 1 , wherein the executable module provides managed access to a specialty engine.
10. The system of claim 1 , wherein the target address space executes the executable code via an API or other service call.
11. A method, comprising:
allocating a shared memory segment of the memory for two non-privileged address spaces, the first comprising a home address space and the second comprising a target address space;
loading one or more executable modules in a private address space of the home address space; and
building in the home address space one or more program call routines and an environment to schedule system request blocks;
wherein the environment to schedule system request blocks is configured to be used to schedule an SRB into the target address space, the SRB comprising information configured to cause the target address space to cause an associated one of the executable modules to execute.
12. The method of claim 11 , further comprising identifying a task control block (TCB) associated with the target address space.
13. The method of claim 11 , wherein the target address space is configured to execute the executable module from the shared memory segment.
14. The method of claim 13 , wherein the target address space uses an asynchronous exit routine to execute the executable module.
15. The method of claim 14 , wherein an SRB unit of the target address space resumes upon completion of the executable module.
16. The method of claim 14 , wherein a cross-memory post is sent by the target address space to the home address to signal completion of the executable module.
17. The method of claim 11 , wherein the executable module comprises a function.
18. The method of claim 11 , wherein the executable module provides shared access to a file or other stored object.
19. The method of claim 11 , wherein the executable module provides managed access to a specialty engine.
20. A computer program product embodied in a non-transitory computer readable medium and comprising computer instructions for:
allocating a shared memory segment of the memory for two non-privileged address spaces, the first comprising a home address space and the second comprising a target address space;
loading one or more executable modules in a private address space of the home address space; and
building in the home address space one or more program call routines and an environment to schedule system request blocks;
wherein the environment to schedule system request blocks is configured to be used to schedule an SRB into the target address space, the SRB comprising information configured to cause the target address space to cause an associated one of the executable modules to execute.
