System parameter trace and test coverage optimization in a computer system

A method of controlling devices in a computer system, the method comprising:

• communicating, by a trace and optimize function controller (TOF) in a controller of a hardware platform in the computer system, with a processor, a system memory, a plurality of input/output (IO) devices, and one or more out-of-band utilities on a software platform in the computer system, to obtain respective current settings thereof, wherein the computer system comprises a plurality of components, wherein the plurality of components includes the processor, the system memory, and the plurality of IO devices, wherein at least one component of the processor, the system memory, and the plurality of IO devices is controlled by the one or more out-of-band utilities, wherein the one or more out-of-band utilities provide out-of-band control settings to the at least one component, and wherein the obtained current settings comprise the out-of-band control settings for the at least one component;
• determining, by the TOF, optimized final settings for the processor, the system memory, and the plurality of IO devices based on combining the obtained current settings, wherein the optimized final settings determined by the TOF prevent the controller from overriding the out-of-band control settings for the at least one component by the controller;
• and
• controlling, by the controller, the processor, the system memory, and the plurality of IO devices based on the optimized final settings.

A computer program product for controlling devices in a computer system the computer program product comprising:

• a non-transitory computer-readable storage medium storing a plurality of computer program instructions, the computer program instructions executable by one or more computer processors to:
• communicate, by a trace and optimize function controller (TOF) in a controller of a hardware platform in the computer system, with a processor, a system memory, a plurality of input/output (IO) devices, and one or more out-of-band utilities on a software platform in the computer system, to obtain respective current settings thereof, wherein the computer system comprises a plurality of components, wherein the plurality of components includes the processor, the system memory, and the plurality of IO devices, wherein at least one component of the processor, the system memory, and the plurality of IO devices is controlled by the one or more out-of-band utilities, wherein the one or more out-of-band utilities provide out-of-band control settings to the at least one component, and wherein the obtained current settings comprise the out-of-band control settings for the at least one component;
• determine, by the TOF, optimized final settings for the processor, the system memory, and the plurality of IO devices based on combining the obtained current settings, wherein the optimized final settings determined by the TOF prevent the controller from overriding the out-of-band control settings for the at least one component by the controller;
• and
• control, by the controller, the processor, the system memory, and the plurality of IO devices based on the optimized final settings.
