This patch extracts information on CPU topology and capability and put them
under the `/acrn-config/processors` node in the board XML.
The added information can be divided into two categories.
1. The topology of CPUs like the following. Each thread (which is a leaf
node in the topology) contains its addresses (i.e. CPU ID, APIC ID,
x2APIC ID) and model identifiers (i.e. family, model, stepping IDs, core
types and native model ID).
<die id="0">
<core id="0x0">
<thread id="0x0">
<cpu_id>0</cpu_id>
<apic_id>0x0</apic_id>
<x2apic_id>0x0</x2apic_id>
<family_id>0x6</family_id>
<model_id>0x9e</model_id>
<stepping_id>0x9</stepping_id>
<core_type></core_type>
<native_model_id></native_model_id>
</thread>
<thread id="0x1"> ... </thread>
</core>
<core id="0x1">
<thread id="0x2"> ... </thread>
<thread id="0x3"> ... </thread>
</core>
<core id="0x2">
<thread id="0x4"> ... </thread>
<thread id="0x5"> ... </thread>
</core>
<core id="0x3">
<thread id="0x6"> ... </thread>
<thread id="0x7"> ... </thread>
</core>
</die>
2. The CPU models identified by the quadruple (family_id, model_id,
core_type, native_model_id). Each model is described by its brandstring
and capabilities, both of which are fetched from CPUID leaves.
<model description="Intel(R) Core(TM) i7-7700 CPU @ 3.60GHz">
<family_id>0x6</family_id>
<model_id>0x9e</model_id>
<core_type></core_type>
<native_model_id></native_model_id>
<capability id="sse3"/>
<capability id="pclmulqdq"/>
<capability id="dtes64"/>
<capability id="monitor"/>
...
</model>

board_parser.py will collect all board related info and then generate a board info file for acrn-config host tool usage. usage: python3 run.py <board_name> [--out board_info_file] board_name : the name of board that run ACRN hypervisor, like apl-up2/nuc7i7dnb. It will be used as name of the board configurations folder which created by acrn-config host tool. board_info_file : (optional) the name of board info file. if it is not specified, a name of <board_name>.xml will be generated under the current working directory by default. Please run this script under native Linux environment with root privilege. OS requirement: Release: Ubuntu 18.04+ or ClearLinux 30210+ Tools: cpuid, rdmsr, lspci, dmidecode kernel cmdline: "idle=nomwait intel_idle.max_cstate=0 intel_pstate=disable"
