tools/testing/nvdimm: fix allocation range for mock flush hint tables

2016-09-19T20:49:48+00:00

Commit 480b6837aa57 "nvdimm: fix PHYS_PFN/PFN_PHYS mixup" identified
that we were passing an invalid address to devm_nvdimm_ioremap(). With
that fixed it exposed a bug in the memory reservation size for flush
hint tables.  Since we map a full page we need to mock a full page of
memory to back the flush hint table entries.

tools/testing/nvdimm: fix SIGTERM vs hotplug crash

2016-08-10T22:59:09+00:00

The unit tests crash when hotplug races the previous probe. This race
requires that the loading of the nfit_test module be terminated with
SIGTERM, and the module to be unloaded while the ars scan is still
running.

In contrast to the normal nfit driver, the unit test calls
acpi_nfit_init() twice to simulate hotplug, whereas the nominal case
goes through the acpi_nfit_notify() event handler.  The
acpi_nfit_notify() path is careful to flush the previous region
registration before servicing the hotplug event. The unit test was
missing this guarantee.

nfit: move to nfit/ sub-directory

2016-07-24T15:04:04+00:00

With the arrival of x86-machine-check support the nfit driver will add a
(conditionally-compiled) source file.  Prepare for this by moving all
nfit source to drivers/acpi/nfit/.  This is pure code movement, no
functional changes.

nfit, tools/testing/nvdimm/: unify shutdown paths

2016-07-22T20:35:54+00:00

While testing the new on-demand ARS patches we discovered that
differences between the nfit_test and normal nfit driver shutdown paths
can leak resources.  Unify the shutdown paths to trigger via a devm_
callback when the acpi_desc->dev is unbound from its driver.

libnvdimm: move ->module to struct nvdimm_bus_descriptor

2016-07-22T03:03:19+00:00

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.
