Abstract: Techniques for enabling inter-subsystem resource sharing are provided. The techniques include providing an RPC client on a first subsystem for acting as a proxy for a resource of a second subsystem. When the first subsystem receives a request from an application to access the resource, the RPC client may invoke a function of an RPC server associated with the second subsystem. The RPC server may load the resource on the second subsystem. The RPC client may then act as a proxy for the resource.

Abstract: An apparatus and method provide for profile optimizations at a binary level. Thread specific data may be used to lay out a procedure in a binary. In one example, a hot thread may be identified and a layout may be generated based on the identified hot thread. Also, threads of an application may be ranked according to frequency of execution of the corresponding threads. The layout may be created based on the different threads of differing frequency of execution and conflicts between a hottest thread and each of the other threads of the application. In another example, different threads of the application may conflict. For example, two threads may contain operations that overlap temporally to create a race condition. A layout of the application threads may be created based on conflicting threads.

Abstract: Techniques for extending operating system subsystems are provided. The techniques involve using a subsystem of an operating system having a set of insertion points that identify points in the program logic of the subsystem where logic extensions may be added. The subsystem may receive a library that has functions comprising program logic for extending the subsystem and a list that provides a correspondence between the insertion points and the functions. When the subsystem receives a request to perform an action that has a corresponding insertion point for which the list provides an associated function, the subsystem may perform the function. The function may be indicated to be performed at various points in the program logic of the subsystem, including before or after the requested action.

Abstract: Technologies for estimating deviations in the performance characteristics of a newer version of software relative to an older version. Such performance characteristics include cache misses, pages faults, and the like. Estimations are typically made by instrumenting and profiling an older version binary, determining differences in code blocks between the older and a newer version, propagating profile data from the older version to the newer version based on a simulation heuristic, and estimating performance deviations based on the older version, the profile data, configuration parameters, and the changes in the newer version without actually executing the newer version of the binary.

Abstract: Techniques for extending operating system subsystems are provided. The techniques involve receiving a library that provides functions that extend an application program interface of the subsystem of the operating system. The techniques dynamically add a set of local procedure call ports or system call numbers corresponding to functions provided by the library and provide a known local procedure call port for receiving requests to identify a dynamically added local procedure call port or system call number. When a function of the library is requested, the subsystem determines the dynamically added port or system call number corresponding to the function, and provides an indication of the determined port or system call number to a requester of the function. The requester of the function may then invoke the function using the indicated dynamically added port or system call number.
