Introduction: ============= CXL Persistent Memory (Pmem) devices region, namespace and content must be persistent across system reboot. In order to achieve this persistency, it uses Label Storage Area (LSA) to store respective metadata. During system reboot, stored metadata in LSA is used to bring back the region, namespace and content of CXL device in its previous state. CXL specification provides Get_LSA (4102h) and Set_LSA (4103h) mailbox commands to access the LSA area. nvdimm driver is using same commands to get/set LSA data.
Hi Jonathan, Dave and Ira I have addressed the review comments of V1 patch-set and sent out this V2 Patch-set. 0-Day Kernel Test bot has reported couple of minor issues which I will address in next series. Can you please have a look at this V2 series and let me know your feedback. Regards, Neeraj
