2015-10-12 · Steps to boot from an NVDIMM PMEM namespace: 1) Find NFIT table 2) Search for PMEM namespaces. Looking at SPA tables is enough 3) Get the address and length of the area 4) Check Linux magic numbers and flags 5) Copy kernel to low memory 6) Boot normally Preliminary implementation: http://www.seabios.org/pipermail/seabios/2015-September/0 09770.html

This way 'virtio-pmem' driver uses existing functionality of pmem driver to register persistent memory compatible for DAX capable filesystems. This also provides function to perform guest flush over VIRTIO from 'pmem' driver when userspace performs flush … 2021-3-17 2020-7-9 · PMM/PMEM; In the rest of this document, we'll use the PMEM acronym. The current available PMEM technology available in Grid'5000 is Intel's Optane DC Persistent Memory. Other vendors may provide PMEM in the future (IBM, HPE Memristor ?). PMEM has been also available for tests in emulators such as qemu for a long time.

Case in point, in the latest IBM Power release – Virtual PMem is one of the key new features. With this feature customers can achieve fast restart of a workload – whether for planned downtime or unplanned outage without compromising ongoing performance during normal use.

Being on the memory bus allows PMEM to have DRAM-like access to data, which means that it has nearly the same speed and latency of DRAM and the non-volatility of NAND flash. IBM Power systems started late in the SAP HANA market, on standby if you will when IBM still had their System X business.
