A significant release of the nvme-cli 2.0 utility suite, which provides a command-line interface for managing NVM-Express (NVMe) SSDs on Linux, has been published. Using nvme-cli, you can evaluate the state of the drive, view the error log, display statistics on operations, manage namespaces, send low-level commands to the controller, activate advanced features, etc. The code is written in C and distributed under the GPLv2 license.
The most significant changes that led to the formation of the 2.0 branch are related to the reorganization of the codebase - the libnvme library has been separated from the package, which will now be developed in a separate repository and can be used in arbitrary projects to call the functionality available in nvme-cli. Simultaneously with nvme-cli 2.0, libnvme 1.0 was released, which stabilized the library API. Of the functional changes in nvme-cli 2.0, we can note the addition of new commands "nvme config", "nvme dim", "nvme media-unit-stat-log", "nvme gen-tls-key" and "nvme check-tls-key" .
