** Description changed: [Impact] The support for Intel NVDIMM technology requires both kernel and userspace components. The kernel components have landed in 4.15 and are available in Bionic. In order for users to take advantage of NVDIMMs in their deployments, the following userspace packages are also needed in Bionic: ndctl -- Utility library for managing the libnvdimm (non-volatile memory device) sub-system in the Linux kernel. Upstream project: https://github.com/pmem/ndctl PMDK -- persistent memory toolkit Upstream project: https://github.com/pmem/pmdk/ This SRU is about ndctl; pmdk is being handled in bug #1781269 [Test Case] * Install daxctl and ndctl sudo apt install daxctl ndctl * download the two dep8 test scripts: wget https://git.launchpad.net/~usd-import-team/ubuntu/+source/ndctl/plain/debian/tests/daxctl-commands https://git.launchpad.net/~usd-import-team/ubuntu/+source/ndctl/plain/debian/tests/ndctl-commands * execute them and verify exit status, which should be zero: sh ./daxctl-commands; echo $? sh ./ndctl-commands; echo $?
