Linus Torvalds 88793e5c77 The libnvdimm sub-system introduces, in addition to the libnvdimm-core,
4 drivers / enabling modules:
 
 NFIT:
 Instantiates an "nvdimm bus" with the core and registers memory devices
 (NVDIMMs) enumerated by the ACPI 6.0 NFIT (NVDIMM Firmware Interface
 table).  After registering NVDIMMs the NFIT driver then registers
 "region" devices.  A libnvdimm-region defines an access mode and the
 boundaries of persistent memory media.  A region may span multiple
 NVDIMMs that are interleaved by the hardware memory controller.  In
 turn, a libnvdimm-region can be carved into a "namespace" device and
 bound to the PMEM or BLK driver which will attach a Linux block device
 (disk) interface to the memory.
 
 PMEM:
 Initially merged in v4.1 this driver for contiguous spans of persistent
 memory address ranges is re-worked to drive PMEM-namespaces emitted by
 the libnvdimm-core.  In this update the PMEM driver, on x86, gains the
 ability to assert that writes to persistent memory have been flushed all
 the way through the caches and buffers in the platform to persistent
 media.  See memcpy_to_pmem() and wmb_pmem().
 
 BLK:
 This new driver enables access to persistent memory media through "Block
 Data Windows" as defined by the NFIT.  The primary difference of this
 driver to PMEM is that only a small window of persistent memory is
 mapped into system address space at any given point in time.  Per-NVDIMM
 windows are reprogrammed at run time, per-I/O, to access different
 portions of the media.  BLK-mode, by definition, does not support DAX.
 
 BTT:
 This is a library, optionally consumed by either PMEM or BLK, that
 converts a byte-accessible namespace into a disk with atomic sector
 update semantics (prevents sector tearing on crash or power loss).  The
 sinister aspect of sector tearing is that most applications do not know
 they have a atomic sector dependency.  At least today's disk's rarely
 ever tear sectors and if they do one almost certainly gets a CRC error
 on access.  NVDIMMs will always tear and always silently.  Until an
 application is audited to be robust in the presence of sector-tearing
 the usage of BTT is recommended.
