dax: remove CONFIG_DAX_DRIVER

2021-12-04T16:58:51Z

CONFIG_DAX_DRIVER only selects CONFIG_DAX now, so remove it. Signed-off-by: Christoph Hellwig Reviewed-by: Dan Williams Link: https://lore.kernel.org/r/20211129102203.2243509-4-hch@lst.de Signed-off-by: Dan Williams

lib: Uplevel the pmem "region" ida to a global allocator

2019-11-07T14:44:29Z

In preparation for handling platform differentiated memory types beyond persistent memory, uplevel the "region" identifier to a global number space. This enables a device-dax instance to be registered to any memory type with guaranteed unique names. Signed-off-by: Dan Williams Acked-by: Thomas Gleixner Signed-off-by: Rafael J. Wysocki

libnvdimm: Enable unit test infrastructure compile checks

2019-09-07T07:28:05Z

The infrastructure to mock core libnvdimm routines for unit testing purposes is prone to bitrot relative to refactoring of that core. Arrange for the unit test core to be built when CONFIG_COMPILE_TEST=y. This does not result in a functional unit test environment, it is only a helper for 0day to catch unit test build regressions. Note that there are a few x86isms in the implementation, so this does not bother compile testing this architectures other than 64-bit x86.

docs: nvdimm: convert to ReST

2019-07-15T12:20:25Z

Rename the nvdimm documentation files to ReST, add an index for them and adjust in order to produce a nice html output via the Sphinx build system. At its new index.rst, let's add a :orphan: while this is not linked to the main index.rst file, in order to avoid build warnings. Signed-off-by: Mauro Carvalho Chehab Acked-by: Dan Williams

acpi/nfit, libnvdimm: Add unlock of nvdimm support for Intel DIMMs

2018-12-14T01:54:13Z

Add support to unlock the dimm via the kernel key management APIs. The passphrase is expected to be pulled from userspace through keyutils. The key management and sysfs attributes are libnvdimm generic. Encrypted keys are used to protect the nvdimm passphrase at rest. The master key can be a trusted-key sealed in a TPM, preferred, or an encrypted-key, more flexible, but more exposure to a potential attacker.

Revert "libnvdimm, of_pmem: workaround OF_NUMA=n build error"

2018-04-19T22:10:56Z

With commit df3f126482db ("libnvdimm, of_pmem: use dev_to_node() instead of of_node_to_nid()") it is now possible to allow of_pmem to be built as a module as originally implemented. Signed-off-by: Dan Williams

libnvdimm, of_pmem: workaround OF_NUMA=n build error

2018-04-09T16:10:22Z

Stephen reports that an x86 allmodconfig build fails to build the of_pmem driver due to a missing definition of of_node_to_nid(). That helper is currently only exported in the OF_NUMA=y case. In other cases, ppc and sparc, it is a weak symbol, and outside of those platforms it is a static inline. Until an OF_NUMA=n configuration can reliably support usage of of_node_to_nid() in modules across architectures, mark this driver as 'bool' instead of 'tristate'.
