From: James Sushanth Anandraj <[email protected]> The Intel Optane Persistent Memory OS provisioning specification describes how to support basic provisioning for Intel Optane persistent memory 100 and 200 series for use in different operating modes using OS software.
This patch set introduces a new utility pcdctl that implements basic provisioning as described in the provisioning specification document at https://cdrdv2.intel.com/v1/dl/getContent/634430 . The pcdctl utility provides enumeration and region reconfiguration commands for "nvdimm" subsystem devices (Non-volatile Memory). This is implemented as a separate tool rather than as a feature of ndctl as the steps for provisioning are specific to Intel Optane devices and are as follows. 1..Generate a new region configuration request using this utility. 2. Reset the platform. 3. Use this utility to list the status of operation. James Sushanth Anandraj (4): Documentation/pcdctl: Add documentation for pcdctl tool and commands pcdctl/list: Add pcdctl-list command to enumerate 'nvdimm' devices pcdctl/reconfigure: Add pcdctl-reconfigure-region command pcdctl/reconfigure: Add support for pmem and iso-pmem modes Documentation/pcdctl/Makefile.am | 59 + .../pcdctl/asciidoctor-extensions.rb | 30 + Documentation/pcdctl/pcdctl-list.txt | 56 + .../pcdctl/pcdctl-reconfigure-region.txt | 50 + Documentation/pcdctl/pcdctl.txt | 40 + Documentation/pcdctl/theory-of-operation.txt | 28 + Makefile.am | 4 +- configure.ac | 2 + pcdctl/Makefile.am | 18 + pcdctl/builtin.h | 9 + pcdctl/list.c | 114 ++ pcdctl/list.h | 11 + pcdctl/pcat.c | 59 + pcdctl/pcat.h | 13 + pcdctl/pcd.h | 381 +++++ pcdctl/pcdctl.c | 88 + pcdctl/reconfigure.c | 1458 +++++++++++++++++ pcdctl/reconfigure.h | 12 + util/main.h | 1 + 19 files changed, 2431 insertions(+), 2 deletions(-) create mode 100644 Documentation/pcdctl/Makefile.am create mode 100644 Documentation/pcdctl/asciidoctor-extensions.rb create mode 100644 Documentation/pcdctl/pcdctl-list.txt create mode 100644 Documentation/pcdctl/pcdctl-reconfigure-region.txt create mode 100644 Documentation/pcdctl/pcdctl.txt create mode 100644 Documentation/pcdctl/theory-of-operation.txt create mode 100644 pcdctl/Makefile.am create mode 100644 pcdctl/builtin.h create mode 100644 pcdctl/list.c create mode 100644 pcdctl/list.h create mode 100644 pcdctl/pcat.c create mode 100644 pcdctl/pcat.h create mode 100644 pcdctl/pcd.h create mode 100644 pcdctl/pcdctl.c create mode 100644 pcdctl/reconfigure.c create mode 100644 pcdctl/reconfigure.h -- 2.20.1
