Pynvme is an user-space NVMe test driver with Python API. It is an open, fast, and extensible solution for SSD developers and test engineers to build their own tests intuitively.

1. access PCI configuration space
2. access NVMe registers in BAR space
3. send any NVMe admin/IO commands
4. support callback functions for NVMe commands
5. support MSI/MSIx interrupts
6. transparent checksum verification on every LBA
7. generates IO workload of high performance and low latency
8. support multiple namespaces
9. support multiple tests on different controllers
10. integrate with pytest
11. integrate with VSCode to display cmdlog in GUI
12. support NVMe over TCP targets
13. HMB: Host Memory Buffer (PyNVMe3 only)
14. ZNS: Zoned Namespace (PyNVMe3 only)
15. TCG: security features (PyNVMe3 only)
16. Enterprise and Data Center SSD features (PyNVMe3 only)
17. extensive test scripts (PyNVMe3 only)
