* acpi: make bios_linker_loader_add_pointer() API offset basedIgor Mammedov2016-06-071-4/+3Star
| | | | | | | | | | | | | | | | cleanup bios_linker_loader_add_pointer() API by switching arguments to taking offsets relative to corresponding files instead of doing pointer arithmetic on behalf of user which were confusing. Also make offset inside of source file explicit in API so that user won't have to manually set it in destination file blob and while at it add additional boundary checks.

* acpi: simplify bios_linker API by removing redundant 'table' argumentIgor Mammedov2016-06-071-6/+9
| | | | | | | | | | | | | | | | | | | | | | 'table' argument in bios_linker_add_foo() commands is a data blob of one of files also passed to the same API. So instead of passing blob in every API call, add and keep file name association with related blob at bios_linker_loader_alloc() time. And find blob by name looking up allocated file entries inside of bios_linker_add_foo() commands. It will: - make API less confusing, - enforce calling bios_linker_loader_alloc() before calling any bios_linker_add_foo() - make sure that blob is the correct one, i.e. associated with the right file name Signed-off-by: Igor Mammedov <imammedo@redhat.com> Reviewed-by: Michael S.

* nvdimm: fix header pointer in nvdimm_build_nfit()Haozhong Zhang2016-01-081-3/+5
| | | | | | | | | | | | | | | | | | | | In the current nvdimm_build_nfit(), the pointer 'header' initially equals to table_data->data + table_data->len. However, the following g_array_append_vals(table_data, structures->data, structures->len) may resize and relocate table_data->data[]. Therefore, the usage of 'header' afterwards may be illegal. This patch fixes this issue by storing an offset within table_data->data[] (rather than an address) in 'header'.

* nvdimm acpi: build ACPI NFIT tableXiao Guangrong2015-12-221-0/+382
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.
