The mailing list is tracked by patchwork here: +https://patchwork.kernel.org/project/linux-nvdimm/list/ +...and that instance is configured to give feedback to submitters on +patch acceptance and upstream merge. Patches are merged to either the +'libnvdimm-fixes' or 'libnvdimm-for-next' branch. Those branches are +available here: +https://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm.git/ + +In general patches can be submitted against the latest -rc; however, if +the incoming code change is dependent on other pending changes then the +patch should be based on the libnvdimm-for-next branch. However, since +persistent memory sits at the intersection of storage and memory there +are cases where patches are more suitable to be merged through a +Filesystem or the Memory Management tree. When in doubt copy the nvdimm +list and the maintainers will help route. + +Submissions will be exposed to the kbuild robot for compile regression +testing. It helps to get a success notification from that infrastructure +before submitting, but it is not required. + + +Submit Checklist Addendum +------------------------- +There are unit tests for the subsystem via the ndctl utility: +https://github.com/pmem/ndctl +Those tests need to be passed before the patches go upstream, but not +necessarily before initial posting. Contact the list if you need help +getting the test environment set up. + +ACPI Device Specific Methods (_DSM) +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +Before patches enabling a new _DSM family will be considered, it must +be assigned a format-interface-code from the NVDIMM Sub-team of the ACPI +Specification Working Group. In general, the stance of the subsystem is +to push back on the proliferation of NVDIMM command sets, so do strongly +consider implementing support for an existing command set. See +drivers/acpi/nfit/nfit.h for the set of supported command sets. + + +Key Cycle Dates +--------------- +New submissions can be sent at any time, but if they intend to hit the +next merge window they should be sent before -rc4, and ideally +stabilized in the libnvdimm-for-next branch by -rc6. Of course if a +patch set requires more than 2 weeks of review, -rc4 is already too late +and some patches may require multiple development cycles to review. + + +Review Cadence +-------------- +In general, please wait up to one week before pinging for feedback. A +private mail reminder is preferred. Alternatively ask for other +developers that have Reviewed-by tags for libnvdimm changes to take a +look and offer their opinion. |
