A new sub-system in support of non-volatile memory storage devices.
Stephen, please add libnvdimm-for-next to -next:
Changes since v6 :
1/ Deferred the patches dependent on ->rw_bytes() (BTT - stacked block
driver, BLK - mmio aperture windows driver, NFIT_TEST - unit test
infrastructure for all libnvdimm + nfit components) to their own
patchset. Make the ->rw_bytes() implementation the first patch in
that series (Christoph)
2/ Collected acks from Christoph and Rafael!
3/ Add a HAS_IOMEM dependency to CONFIG_BLK_DEV_PMEM following commit
b6f2098fb708 "block: pmem: Add dependency on HAS_IOMEM" in 4.1-rc8.
4/ Move libnvdimm to subsys_initcall() and move arch/x86/kernel/pmem.c
back to device_initcall(). This allows ACPI_NFIT to be built-in.
5/ Drop the ACPI_DRIVER_ALL_NOTIFY_EVENTS flag in the nfit driver.
6/ Reference count the nvdimm_drvdata object. This fixes a bug that was
found when the unit tests were extended to test disabling an nvdimm
while a region device still had references to label data.
Dan Williams (16):
e820, efi: add ACPI 6.0 persistent memory types
libnvdimm, nfit: initial libnvdimm infrastructure and NFIT support
libnvdimm: control character device and nvdimm_bus sysfs attributes
libnvdimm, nfit: dimm/memory-devices
libnvdimm: control (ioctl) messages for nvdimm_bus and nvdimm devices
libnvdimm, nvdimm: dimm driver and base libnvdimm device-driver infrastructure
libnvdimm, nfit: regions (block-data-window, persistent memory, volatile memory)
libnvdimm: support for legacy (non-aliasing) nvdimms
libnvdimm, pmem: move pmem to drivers/nvdimm/
libnvdimm, pmem: add libnvdimm support to the pmem driver
libnvdimm, nfit: add interleave-set state-tracking infrastructure
libnvdimm: namespace indices: read and validate
libnvdimm: pmem label sets and namespace instantiation.
libnvdimm: blk labels and namespace instantiation
libnvdimm: write pmem label set
libnvdimm: write blk label set
We have been successfully running this patchset on our NFIT-enabled
prototype systems with pmem. (Intel example _DSM, label, blk are not
available for testing.)
So for patch 1/16 to 4/15, and 6/16 to 10/16.
