Demand based USB proxy for data stores in service processor complex

A system comprising:

• a processor;
• a platform controller;
• an I/O controller capable of generating a System Management Interrupt (SMI);
• a memory coupled to the processor, the memory comprising instructions for performing the following:
• in response to an event requiring secure access to data, generating an SMI to cause the system to enter System Management Mode;
• using a resource of the platform controller to create an emulated USB device, wherein the resource stores the data;
• copying the data from the resource using the emulated USB device via a connection inaccessible by an operating system of the system;
• and
• processing the data prior to exiting System Management Mode.

A computer program product comprising:

• a non-transitory computer-readable storage medium;
• and
• instructions in the non-transitory computer-readable storage medium, wherein the instructions, when executed in a processing system having a platform controller coupled to an I/O controller capable of generating a System Management Interrupt (SMI), cause the processing system to perform operations comprising:
• in response to an event requiring secure access to data, generating an SMI to cause the system to enter System Management Mode;
• using a resource of the platform controller to create an emulated USB device, wherein the resource stores the data;
• copying the data from the resource using the emulated USB device via a connection inaccessible by an operating system of the system;
• and
• processing the data prior to exiting System Management Mode.
