External Paging And Swapping For Dynamic Modules

A computing device, comprising:

• an execution memory;
• a storage memory;
• and
• a processor communicatively connected to the execution memory and the storage memory, wherein the processor is configured with processor-executable instructions to cause the processor to execute operations comprising:
• assigning static virtual addresses to a base image and dynamic modules of a static image of firmware of the computing device from a virtual address space for the static image;
• decomposing the static image into the base image and the dynamic modules;
• loading the base image to the execution memory during a boot time from a first partition of the storage memory;
• reserving a swap pool in the execution memory during the boot time;
• and
• loading a first dynamic module of the dynamic modules to the swap pool from a second partition of the storage memory during a run time;
• determining users of the first dynamic module;
• incrementing a reference count for each user determined to be using the first dynamic module;
• and
• decrementing the reference count for each user determined to no longer be using of the first dynamic module.
