Reconfigurable recovery modes in high availability processors

A system with reconfigurable recovery modes, the system comprising:

• a processor comprising hardware error recovery resources configured to perform hardware-based error recovery and general purpose resources configured to perform instruction processing, the system configured to perform a method comprising:
• creating, by the processor, a software recovery checkpoint;
• dynamically switching, by the processor, into a non-recoverable processing mode of operation based on creating the software recovery checkpoint, the non-recoverable processing mode of operation being a mode in which a subset of the hardware error recovery resources are powered-down or re-purposed for instruction processing;
• determining, during the non-recoverable processing mode of operation, that a new software recovery checkpoint is required;
• and
• based on the determining that a new software recovery checkpoint is required, dynamically switching into a recoverable processing mode of operation, the recoverable processing mode of operation being a mode in which hardware error recovery resources, including at least one of the hardware error recovery resources in the subset, are purposed for hardware error recovery operations.
