config ACPI_NFIT tristate "ACPI NVDIMM Firmware Interface Table (NFIT)" depends on PHYS_ADDR_T_64BIT depends on BLK_DEV depends on ARCH_HAS_MMIO_FLUSH select LIBNVDIMM help Infrastructure to probe ACPI 6 compliant platforms for NVDIMMs (NFIT) and register a libnvdimm device tree. In addition to storage devices this also enables libnvdimm to pass ACPI._DSM messages for platform/dimm configuration. To compile this driver as a module, choose M here: the module will be called nfit. config ACPI_NFIT_DEBUG bool "NFIT DSM debug" depends on ACPI_NFIT depends on DYNAMIC_DEBUG default n help Enabling this option causes the nfit driver to dump the input and output buffers of _DSM operations on the ACPI0012 device and its children. This can be very verbose, so leave it disabled unless you are debugging a hardware / firmware issue.
