A Hello-World for LightNVM, useful tools for both QEMU and real hardware implementations of the LightNVM (OpenChannel SSD) project.
This folder contains config files for various incarnations of the lightnvm linux kernel. The naming convnention is config. where is the start of the sha key for the linux-lightnnvm fork of the main link kernel (https://github.com/OpenChannelSSD/linux).
There is also a simple build shell script with rules on how to build the kernel on debian/ubuntu based systems.
This folder contains some useful scripts for managing the lighnvm fork of QEMU to enable testing without physical lightnvm compliant block devices. The QEMU fork is at https://github.com/OpenChannelSSD/qemu-nvme.
This is a submodule pointing to the lightnvm branch of the nvme-cli project. Refer to the README in the submodule for more information.
This is a sanity test ;-). Run the python script called lnvm_test.py with appropriate arguments to create and test lightnvm block devices that use kernel plug-ins as the FTL. 'python lnvm_test.py -h' gives an overview of the available commands.Sanity uses the most excelent fio tool in order to test the createdblock device.
Useful arguments are:
-g: Execute a set of auto-generated fio tests
-s: Execute any fio tests (*.fio) in fio_tests/
A bash script called sanity.sh is also provided as an alternative for single fio tests.
Note that both scripts must be launched with root privileges due to fio
TODO: -c: Add single test support as in sanity.sh
TODO: Load/unload LightNVM target for each test
Pull requests and patches gratefully received ;-).
