TLDR
In this paper, a system, method and interface for consistently capturing kernel resident information are provided, and a user mode module initiates a kernel mode information request through an application program interface identifying one or more process threads of interest.Abstract:
A system, method and interface for consistently capturing kernel resident information are provided. An operating system architecture includes user mode modules and kernel mode applications. A user mode module initiates a kernel mode information request through an application program interface identifying one or more process threads of interest. A kernel mode module captures information corresponding to standard kernel mode information and corresponding to the specifically identified process threads. The information is returned in a pre-allocated buffer.read more

TL;DR: In this article, a computationally implemented method includes, but is not limited to acquiring subjective user state data including data indicating incidence of at least a first subjective user states associated with a first user and data indicating the incidence of a second subjective state associated with another user.
Patent
Kernel validation layer
TL;DR: In this article, the authors present a kernel application programming interface validation device that includes a monitoring engine for monitoring incoming kernel mode calls, an analysis engine operable to examiner kernel modes calls, and a validation engine operating to determine if a kernel mode call is valid using the results of the analysis engine.
Patent
Method and apparatus for operating system event notification mechanism using file system interface
TL;DR: A method and structure for notifying operating system events, including standard filesystem interfaces provided for event consumers to use for one or more of registering for event notifications of a set of events, receiving an event notification when each event occurs, and getting details of events that have occurred.
Patent
Method and apparatus for analyzing an application
TL;DR: In this article, a method for analyzing an application involving obtaining a thread dump of a plurality of threads executing the application, analyzing the thread dump to obtain a result using an aggregation mechanism, and determining a potential error location in source code of the application using the result.

Method and system for accessing system resources of a data processing system utilizing a kernel-only thread within a user process
TL;DR: In this article, a thread scheduler schedules selected ones of the first kernel threads and the second kernel thread to the processor for execution, such that access to the system resources by the user process is accomplished by invoking a kernel thread within a user process without invoking another thread within the kernel process.

Source-level debugging of client dump image in a computer network
TL;DR: In this article, the authors present a debugging tool ICAT for the JavaOS operating system, which can be used to determine the cause of a failure of a client's computer. But ICAT requires the client to send a dump image to the server before rebooting, so that the cause can be determined.
Patent
Method and arrangements for generating debugging information following software failures
TL;DR: In this article, the authors present a method to reduce the required amount of data required to conduct postmortem analysis following a computer failure by gathering thread, callstack and thread context information for the running thread, process identifying information associated with the running threads, and information identifying the reason for generating the dump file.

Method and apparatus for external crash analysis in a multitasking operating system
TL;DR: In this article, a method for investigating the operation of processes of an application program running on a multitasking operating system of a computer system to determine if any of the processes have stopped for a predetermined exception incident, by identifying to the operating system a plurality of predetermined exceptions to be investigated; instructing said operating system to stop a process when it encounters one of the predetermined exception incidents; scanning the computer system periodically for stopped processes; determining whether a stopped process has been identified as having encountered a predetermined exceptions incident; and performing a predetermined action if the process has encountered a preemptive action

Application-level access to kernel input/output state
Daniela Rosu,Marcel-Catalin Rosu +1 more
TL;DR: In this paper, a technique for tracking a state of one or more input/output (I/O) channels associated with an application, by the application itself, comprises the steps of: (i) storing, by an operating system kernel, selected elements of the state of at least a portion of the one OR more I/O channels associated to the application in a memory which is shared by both the application and the operating system.
