Beschreibung
Zusammenfassung:	Mechanisms for booting a service processor are provided. With these mechanisms, the service processor executes a secure boot operation of secure boot firmware to boot an operating system kernel of the service processor. The secure boot firmware records first measurements of code executed by the secure boot firmware when performing the boot operation, in one or more registers of a tamper-resistant secure trusted dedicated microprocessor of the service processor. The operating system kernel executing in the service processor enables an integrity management subsystem of the operating system kernel which records second measurements of software executed by the operating system kernel, in the one or more registers of the tamper-resistant secure trusted dedicated microprocessor.
