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.
- access PCI configuration space
- access NVMe registers in BAR space
- send any NVMe admin/IO commands
- support callback functions for NVMe commands
- support MSI/MSIx interrupts
- transparent checksum verification on every LBA
- generates IO workload of high performance and low latency
- support multiple namespaces
- support multiple tests on different controllers
- integrate with pytest
- integrate with VSCode to display cmdlog in GUI
- support NVMe over TCP targets
