Abstract: Example implementations relate to a self-tune controller. For example, the self-tune controller may poll, via an out-of-band data stream, low-level operation information about a processor or a bus of a computing system under a present workload. At least some of the low-level operation information may be descriptive of a nature of traffic on the bus. The self-tune controller may program, via an out-of-band control signal, a setting of the computing system for the present workload based on the low-level operation information.

Abstract: A technique includes, in a first phase of a secure boot of a computer system, executing boot code of the computer system to access a first version of a secure boot key database to authenticate driver code. The first version of the secure boot key database stores a key corresponding to a plurality of drivers. The technique includes executing the boot code to automatically prepare the secure boot key database for a second phase of the secure boot in which operating system bootloader code is executed. Preparing for the second phase includes executing the boot code to automatically replace the first version of the secure boot key database with a second version of the secure boot key database, and the second version of the secure boot key database stores a key, which corresponds to the operating system bootloader code. The technique includes in the second phase of the secure boot, executing the boot code to access the secure boot key database to authenticate the operating system bootloader code.

Abstract: Examples disclosed herein relate to an approach to take a startup inventory of a computing including multiple startup components, where the startup inventory includes information about the at least one processing element, at least one memory device, a system board, and a bus device on a bus. The startup inventory is compared to a stored inventory taken when the computing device was put into a first mode to determine whether the startup inventory and the stored inventory match. A security action is performed in response to the comparison.

Abstract: A method for configuring a computer system memory, includes powering on the computer system; retrieving options for initializing the computer system; assigning to a first segment of the memory a first pre-defined setting; assigning to a second segment of the memory a second pre-defined setting; and booting the computer system.
