NVIDIA Ratchet Level#
The NVIDIA ratchet fuses are burned at the NVIDIA production line.
These fuses cannot be programmed from software.
For NVIDIA owned firmware, if any security loophole is found, then based on the criticality of the issue, the NVIDIA ratchet level can be updated.
An N bit NVIDIA ratchet fuse field can represent numeric value 0-2^N-1. (i.e., an absolute value is programmed in NVIDIA ratchet fuse).
