ACPI: NFIT: Fix support for variable 'SPA' structure size

2021-05-12T19:38:25Z

ACPI 6.4 introduced the "SpaLocationCookie" to the NFIT "System Physical Address (SPA) Range Structure". The presence of that new field is indicated by the ACPI_NFIT_LOCATION_COOKIE_VALID flag. Pre-ACPI-6.4 firmware implementations omit the flag and maintain the original size of the structure. Update the implementation to check that flag to determine the size rather than the ACPI 6.4 compliant definition of 'struct acpi_nfit_system_address' from the Linux ACPICA definitions. Update the test infrastructure for the new expectations as well, i.e. continue to emulate the ACPI 6.3 definition of that structure. Without this fix the kernel fails to validate 'SPA' structures and this leads to a crash in nfit_get_smbios_id() since that routine assumes that SPAs are valid if it finds valid SMBIOS tables.

tools/testing/nvdimm: Make symbol '__nfit_test_ioremap' static

2021-05-12T19:37:14Z

The sparse tool complains as follows: tools/testing/nvdimm/test/iomap.c:65:14: warning: symbol '__nfit_test_ioremap' was not declared. Should it be static? This symbol is not used outside of iomap.c, so this commit marks it static.

A config array is used to hold the dimms for each bus. These dimms are registered with nvdimm, and new nvdimms are created on the buses. Signed-off-by: Santosh Sivaraj Link: https://lore.kernel.org/r/20201222042240.2983755-4-santosh@fossix.org Signed-off-by: Dan Williams

ndtest: Add compatability string to treat it as PAPR family

2021-01-28T08:22:49Z

Since this module is written to be platform agnostic, the module is made part of the PAPR_FAMILY. ndctl identifies the family using the compatible string inside of_node dir-entry.

testing/nvdimm: Add test module for non-nfit platforms

2021-01-28T08:22:48Z

The current test module cannot be used for testing platforms (make check) that do not have support for NFIT. In order to get the ndctl tests working, we need a module which can emulate NVDIMM devices without relying on ACPI/NFIT. The aim of this proposed module is to implement a similar functionality to the existing module but without the ACPI dependencies. This RFC series is split into reviewable and compilable chunks. This patch adds a new driver and registers two nvdimm bus needed for ndctl make check.
