WHEA "builds on the PCI Express Advanced Reporting to provide more detailed information about system errors and a common reporting structure." [4] WHEA allows third-party software to interact with the operating system and react to certain hardware events.
Serviceability or maintainability is the simplicity and speed with which a system can be repaired or maintained; if the time to repair a failed system increases, then availability will decrease. Serviceability includes various methods of easily diagnosing the system when problems arise. Early detection of faults can decrease or avoid system ...
The Problem Reports and Solutions Control Panel applet was replaced by the Maintenance section of the Action Center on Windows 7 and Server 2008 R2.. A new app, Problem Steps Recorder (PSR.exe), is available on all builds of Windows 7 and enables the collection of the actions performed by a user while encountering a crash so that testers and developers can reproduce the situation for analysis ...
Some motherboards have a built-in display to diagnose hardware problems. Most also report POST errors with audible beeps, if a PC speaker is attached. Such motherboards make POST cards less necessary. When these diagnostic cards were first introduced motherboards were expensive and well worth troubleshooting and repairing.
During the POST, the BIOS must integrate multiple competing, changing, and even mutually exclusive standards and initiatives for the matrix of hardware and operating systems the PC is expected to support, although at most only simple memory tests and the setup screen are displayed.
A crash reporter is usually a system software whose function is to identify reporting crash details and to alert when there are crashes, in production or on development / testing environments. Crash reports often include data such as stack traces , type of crash, trends and version of software.
Management Component Transport Protocol (MCTP) is a protocol designed by the Distributed Management Task Force (DMTF) to support communications between different intelligent hardware components that make up a platform management subsystem, providing monitoring and control functions inside a managed computer system.
Physical functions have the ability to move data in and out of the device while virtual functions are lightweight PCIe functions that support data flowing but also have a restricted set of configuration resources. The virtual or physical functions available to the hypervisor or guest operating system depend on the PCIe device. [3]
