[PATCH 1/4] libndctl: Unify adding dimms for papr and nfit families

[PATCH 1/4] libndctl: Unify adding dimms for papr and nfit families

[Santosh Sivaraj]

In preparation for enabling tests on non-nfit devices, unify both, already very
similar, functions into one. This will help in adding all attributes needed for
the unit tests. Since the function doesn't fail if some of the dimm attributes
are missing, this will work fine on PAPR platforms though only part of the DIMM
attributes are provided (This doesn't mean that all of the DIMM attributes can
be missing).

[PATCH 2/4] test: Don't skip tests if nfit modules are missing

[Santosh Sivaraj]

For NFIT to be available ACPI is a must, so don't fail when nfit modules
are missing on a platform that doesn't support ACPI.

[PATCH 3/4] papr: Add support to parse save_fail flag for dimm

[Santosh Sivaraj]

This will help in getting the dimm fail tests to run on papr family too.
Also add nvdimm_test compatibility string for recognizing the test module.

[PATCH 4/4] Use page size as alignment value

[Santosh Sivaraj]

The alignment sizes passed to ndctl in the tests are all hardcoded to 4k,
the default page size on x86. Change those to the default page size on that
architecture (sysconf/getconf). No functional changes otherwise.

Re: [PATCH 1/4] libndctl: Unify adding dimms for papr and nfit families

[Santosh Sivaraj]

Sorry, I missed to provide the version in the subject, this is v4 of the series.

Santosh Sivaraj <santosh@fossix.org> writes:

I am wondering whether it is confusing to call this as
NVDIMM_FAMILY_PAPR. If you are looking at a platform agnoistic family we
should probably name it accordingly. Maybe NVDIMM_FAMILY_TEST ?
