Abstract: A method and apparatus of a device that captures a stackshot of an executing process is described. In an exemplary embodiment, the device detects an interrupt of the process occurring during the execution of the process, where the process execution can be in a kernel space and user space, and the interrupt occurs during the user space. The device further determines whether to capture a stackshot during the interrupt using a penalty function. If the stackshot is to be captured, the device captures the stackshot and saves the stackshot.

Abstract: A method and an apparatus for establishing an operating environment by certifying a code image received from a host over a communication link are described. The code image may be digitally signed through a central authority server. Certification of the code image may be determined by a fingerprint embedded within a secure storage area such as a ROM (read only memory) of the portable device based on a public key certification process. A certified code image may be assigned a hash signature to be stored in a storage of the portable device. An operating environment of the portable device may be established after executing the certified code.

Abstract: Methods, machine-readable tangible storage media, and data processing systems that enable a debug host device to acquire memory dump information from a debug target device after the target device suffers an unrecoverable system malfunction are disclosed. In one embodiment, data in the volatile memory on a debug target device is accessed via a hardware integrated debug framework, which is also used to access data on a nonvolatile electronically erasable semiconductor memory of a debug target device, and one or more registers of one or more processors on a debug target device, and a core dump is created on the debug host device.
