ndctl

ndctl is a command line tool that stands for "Non-Volatile Device Control". It is a utility included in the ndctl package, which is often used to manage and configure persistent memory devices (PMEM) in Linux systems.

With ndctl, users can perform various tasks such as creating, removing, and managing namespaces on PMEM devices. Namespaces allow users to partition PMEM devices and treat them as individual block devices.

The tool also provides options to view information about PMEM devices and their current configuration. Users can query device health, firmware versions, and available features. Additionally, ndctl allows users to monitor and view performance statistics related to PMEM devices.

Moreover, ndctl supports commands for updating firmware on supported devices, which is crucial for maintaining device compatibility and ensuring optimal performance. It also supports features like secure erase and power management settings.

ndctl is designed to work with kernel-level libraries, such as libndctl, which provide an API for programmatic interaction with PMEM devices. This allows developers to incorporate ndctl functionality into their own applications and scripts, automating management tasks or integrating PMEM support into their software.
