2015-12-22acpi: aml: add helper for Opcode Arg2 Arg2 [Dst] AML patternIgor Mammedov1-29/+32
Currently AML API doesn't compose terms in form of following pattern: Opcode Arg2 Arg2 [Dst] but ASL used in piix4/q35 DSDT ACPI tables uses that form, so for clean conversion of it, AML API should be able to handle an optional 'Dst' argumet used there. Since above pattern is used by arithmetic/bit ops, introduce helper that they could reuse. It reduces code duplication in existing 5 aml_foo() functions and also will prevent more duplication when exiting functions are extended to support optional 'Dst' argument.

2015-12-22nvdimm acpi: build ACPI NFIT tableXiao Guangrong9-1/+425
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.
