• bc9775d86   libnvdimm: move ->module to struct nvdimm_bus_descriptor ... Browse Code »

  Let the provider module be explicitly passed in rather than implicitly
  assumed by the module that calls nvdimm_bus_register(). This is in
  preparation for unifying the nfit and nfit_test driver teardown paths.

• f0f4711aa   x86, kexec, nvdimm: Use walk_iomem_res_desc() for iomem search ... Browse Code »

  Change the callers of walk_iomem_res() scanning for the
  following resources by name to use walk_iomem_res_desc()
  instead.

  "ACPI Tables"
  "ACPI Non-volatile Storage"
  "Persistent Memory (legacy)"
  "Crash kernel"

  Note, the caller of walk_iomem_res() with "GART" will be removed
  in a later patch.

  Rather than punt on the numa node for these e820 ranges try to find a
  better answer with memory_add_physaddr_to_nid() when it is available.

• 004f1afbe   libnvdimm, pmem: direct map legacy pmem by default ... Browse Code »

  The expectation is that the legacy / non-standard pmem discovery method
  (e820 type-12) will only ever be used to describe small quantities of
  persistent memory. Larger capacities will be described via the ACPI
  NFIT. When "allocate struct page from pmem" support is added this default
  policy can be overridden by assigning a legacy pmem namespace to a pfn
  device, however this would be only be necessary if a platform used the
  legacy mechanism to define a very large range.

• 7a67832c7   libnvdimm, e820: make CONFIG_X86_PMEM_LEGACY a tristate option ... Browse Code »

  We currently register a platform device for e820 type-12 memory and
  register a nvdimm bus beneath it. Registering the platform device
  triggers the device-core machinery to probe for a driver, but that
  search currently comes up empty. Building the nvdimm-bus registration
  into the e820_pmem platform device registration in this way forces
  libnvdimm to be built-in. Instead, convert the built-in portion of
  CONFIG_X86_PMEM_LEGACY to simply register a platform device and move the
  rest of the logic to the driver for e820_pmem, for the following
  reasons:

  1/ Letting e820_pmem support be a module allows building and testing
  libnvdimm.ko changes without rebooting

  2/ All the normal policy around modules can be applied to e820_pmem
  (unbind to disable and/or blacklisting the module from loading by
  default)

  3/ Moving the driver to a generic location and converting it to scan
  "iomem_resource" rather than "e820.map" means any other architecture can
  take advantage of this simple nvdimm resource discovery mechanism by
  registering a resource named "Persistent Memory (legacy)"
