** 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 + + This SRU falls under the hardware enablement category. [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 $? More detailed testing can be executed if the appropriate hardware is available. [Regression Potential] These are NEW packages for bionic. They were accepted into the archive after a lengthy review. It is lintian clear, with appropriate overrides or an explanation in README.source. This package includes libraries, which could inadvertently become new dependencies. If a package has support for ndctl, for example, but it was always disabled because there was no ndctl in the archive, it could now be inadvertently enabled merely by having the lib*-dev package(s) installed. Similarly, code paths in existing packages that would never have been traversed because of the lack of ndctl support, now could be exposed. [Other Info] The git master branch at https://git.launchpad.net/~ahasenack/ubuntu/+source/ndctl/log/?h=master shows all the work that was put into this package to make it suitable for Ubuntu inclusion. The bug at https://bugs.launchpad.net/bugs/1752378 also contains a lengthy history and discussions about some of the finer details, and is linked to from files in debian/* where further explanation was necessary about some behavior.
