The Non-Volatile Memory Device (NVDIMM) subsystem updates were merged today for the in-development Linux 6.19 kernel. Most notable this cycle for the NVDIMM code is a new open-source driver addition courtesy of Microsoft.

As talked about on Phoronix one month ago, a Microsoft Linux engineer working in official capacity at Microsoft has contributed a “RAMDAX” driver for Linux to allow carving out regions of memory to create persistent memory interfaces exposed as NVDIMM devices.
