From f6a0d06ba72a0c493e1e05872caf2f3781af316d Mon Sep 17 00:00:00 2001 From: Eric Auger Date: Fri, 8 Mar 2019 19:20:53 +0100 Subject: [PATCH] machine: Move nvdimms state into struct MachineState As NVDIMM support is looming for ARM and SPAPR, let's move the acpi_nvdimm_state to the generic machine struct instead of duplicating the same code in several machines. It is also renamed into nvdimms_state and becomes a pointer. nvdimm and nvdimm-persistence become generic machine options. They become guarded by a nvdimm_supported machine class member. We also add a description for those options.
