NVDIMM Updates For The Linux 4.9 Kernel

Written by Michael Larabel in Hardware on 11 October 2016 at 06:35 AM EDT. Add A Comment

The non-volatile DIMM (NVDIMM) support has been updated for the Linux 4.9 kernel merge window.

The NVDIMM kernel changes for Linux 4.9 include PMEM sub-division support so a single PMEM region can be divded into multiple name-spaces, Device DAX unified mode, a rework of the hardware error scrubbing code, and DIMM health event notifications per the ACPI 6.1 specification. The NVDIMM updates for Linux 4.9 also have an assortment of other bug fixes and code clean-ups.

Those interested in NVDIMM / persistent memory support on Linux can find out more details about the NVDIMM driver changes via this pull request.
