nvdimm acpi: build ACPI NFIT table
NFIT is defined in ACPI 6.0: 5.2.25 NVDIMM Firmware Interface Table (NFIT) Currently, we only support PMEM mode. Each device has 3 structures: - SPA structure, defines the PMEM region info - MEM DEV structure, it has the @handle which is used to associate specified ACPI NVDIMM device we will introduce in later patch. Also we can happily ignored the memory device's interleave, the real nvdimm hardware access is hidden behind host - DCR structure, it defines vendor ID used to associate specified vendor nvdimm driver. Since we only implement PMEM mode this time, Command window and Data window are not needed The NVDIMM functionality is controlled by the parameter, 'nvdimm', which is introduced for the machine, there is a example to enable it: -machine pc,nvdimm -m 8G,maxmem=100G,slots=100 -object \ memory-backend-file,id=mem1,share,mem-path=/tmp/nvdimm1,size=10G -device \ nvdimm,memdev=mem1,id=nv1 It is disabled on default Reviewed-by: Stefan Hajnoczi <stefanha@redhat.com> Signed-off-by: Xiao Guangrong <guangrong.xiao@linux.intel.com> Reviewed-by: Michael S.
