Subject: [PATCH v2 02/12] ACPI: NFIT: Move bus_dsm_mask out of generic nvdimm_bus_descriptor
Date: Mon, 06 Jul 2020 18:58:44 -0700 [thread overview]
Message-ID: <159408712429.2385045.13491275997943890813.stgit@dwillia2-desk3.amr.corp.intel.com> (raw)
In-Reply-To: <159408711335.2385045.2567600405906448375.stgit@dwillia2-desk3.amr.corp.intel.com>
DSMs are strictly an ACPI mechanism, evict the bus_dsm_mask concept from
the generic 'struct nvdimm_bus_descriptor' object.
As a side effect the test facility ->bus_nfit_cmd_force_en is no longer
necessary. The test infrastructure can communicate that information
directly in ->bus_dsm_mask.
