Apparatus and method for providing one time programmable memory features in a hypervisor of a computing device

An electronic device, comprising:

• a non-transitory memory comprising instructions;
• and
• a processor coupled to the non-transitory memory, the instructions being executed by the processor to cause the electronic device to:
• provide a first software process configured to execute at a first privilege level;
• provide a second software process configured to execute at a second privilege level, wherein the first privilege level is more restrictive than the second privilege level;
• initialize, at the first privilege level, a memory pool within the memory;
• allocate, at the first privilege level, a block of memory;
• send a request to write protect the block of memory to the second software process;
• and
• write protect, at the second privilege level, the allocated block of memory.

A method comprising:

• executing a first software process at a first privilege level and a second software process at a second privilege level;
• initializing, at the first privilege level, a memory pool;
• allocating, at the first privilege level, a block of memory;
• and
• write protecting, at the second privilege level, the block of memory,
• wherein the first privilege level is more restrictive than the second privilege level.

A computer program product, the computer program product being embodied in a non-transitory computer readable medium and comprising computer instructions for:

• executing a first software process at a first privilege level and a second software process at a second privilege level;
• initializing, at the first privilege level, a memory pool;
• allocating, at the first privilege level, a block of memory;
• and
• write protecting, at the second privilege level, the block of memory,
• wherein the first privilege level is more restrictive than the second privilege level.
