libnvdimm, nfit: initial libnvdimm infrastructure and NFIT support A struct nvdimm_bus is the anchor device for registering nvdimm resources and interfaces, for example, a character control device, nvdimm devices, and I/O region devices. The ACPI NFIT (NVDIMM Firmware Interface Table) is one possible platform description for such non-volatile memory resources in a system. The nfit.ko driver attaches to the "ACPI0012" device that indicates the presence of the NFIT and parses the table to register a struct nvdimm_bus instance.

libnvdimm: control character device and nvdimm_bus sysfs attributes The control device for a nvdimm_bus is registered as an "nd" class device. The expectation is that there will usually only be one "nd" bus registered under /sys/class/nd. However, we allow for the possibility of multiple buses and they will listed in discovery order as ndctl0...ndctlN. This character device hosts the ioctl for passing control messages. The initial command set has a 1:1 correlation with the commands listed in the by the "NFIT DSM Example" document [1], but this scheme is extensible to future command sets. Note, nd_ioctl() and the backing ->ndctl() implementation are defined in a subsequent patch. This is simply the initial registrations and sysfs attributes.

libnvdimm, nfit: dimm/memory-devices Enable nvdimm devices to be registered on a nvdimm_bus. The kernel assigned device id for nvdimm devicesis dynamic. If userspace needs a more static identifier it should consult a provider-specific attribute. In the case where NFIT is the provider, the 'nmemX/nfit/handle' or 'nmemX/nfit/serial' attributes may be used for this purpose.

libnvdimm, nvdimm: dimm driver and base libnvdimm device-driver infrastructure * Implement the device-model infrastructure for loading modules and attaching drivers to nvdimm devices. This is a simple association of a nd-device-type number with a driver that has a bitmask of supported device types. To facilitate userspace bind/unbind operations 'modalias' and 'devtype', that also appear in the uevent, are added as generic sysfs attributes for all nvdimm devices. The reason for the device-type number is to support sub-types within a given parent devtype, be it a vendor-specific sub-type or otherwise. * The first consumer of this infrastructure is the driver for dimm devices. It simply uses control messages to retrieve and store the configuration-data image (label set) from each dimm. Note: nd_device_register() arranges for asynchronous registration of nvdimm bus devices by default.
