Go language bindings for the ipmctl API for managing SCM/DCPM modules

Go bindings for the libipmctl native C lib to enable management of DCPM modules from Go source

This is a Go interface for ipmctl

The bindings require ipmctl library to be installed. To install please follow steps in the ipmctl github

DeviceDiscovery struct represents Go equivalent of C.struct_device_discovery from nvm_management.h (NVM API) as reported by "go tool cgo -godefs nvm.go"

type IpmCtl 

type IpmCtl interface {
	// SetInterleaved mode for app-direct regions
	// process referred to as "set goal" in NVM API
	//SetRegion(...)
	// Discover persistent memory modules
	Discover() ([]DeviceDiscovery, error)
}

IpmCtl is the interface that provides access to libipmctl.

type NvmMgmt 

type NvmMgmt struct{}

NvmMgmt is an implementation of the IpmCtl interface which exercises libipmctl's NVM API.

func (*NvmMgmt) Discover 

func (n *NvmMgmt) Discover() (devices []DeviceDiscovery, err error)

Discover queries number of SCM modules and retrieves device_discovery structs for each.
