CpuInfo - file /proc/cpuinfo
¶
This parser reads the content of the /proc/cpuinfo
file and parses it
into a dictionary of lists, keyed on the left hand column of the cpuinfo
output.
The object also provides properties for the standard information about the CPU and motherboard architecture.
Sample input:
processor : 0
vendor_id : GenuineIntel
cpu family : 6
model : 45
model name : Intel(R) Xeon(R) CPU E5-2690 0 @ 2.90GHz

Examples
>>> cpu_info.cpu_count
2
>>> sorted(cpu_info.apicid)
['0', '2']
>>> cpu_info.socket_count
2
>>> cpu_info.vendor
'GenuineIntel'
>>> "fpu" in cpu_info.flags
True
>>> cpu_info.model_name
'Intel(R) Xeon(R) CPU E5-2690 0 @ 2.90GHz'
>>> cpu_info.get_processor_by_index(0)['cpus']
'0'
>>> cpu_info.get_processor_by_index(0)['vendors']
'GenuineIntel'
>>> cpu_info.microcode
'1808'

Bases:
LegacyItemAccess
,Parser
CpuInfo parser - able to be used as a dictionary through the LegacyItemAccess mixin class.
The following items are remapped into lists, with the element number corresponding to the CPU. For example, given the following input:
processor : 1 vendor_id : GenuineIntel cpu family : 6 model : 45 model name : Intel(R) Xeon(R) CPU E5-2690 0 @ 2.90GHz stepping : 2 microcode : 1808 cpu MHz : 2900.000 cache size : 20480 KB physical id : 2 siblings : 1 core id : 0 cpu cores : 1 apicid : 2 address sizes : 40 bits physical, 48 bits virtual bugs : cpu_meltdown spectre_v1 spectre_v2 spec_store_bypass l1tf mds swapgs taa itlb_multihit
The following keys would be lists of:
cpus - the processor line (e.g.
1
)sockets - the physical id line (e.g.
2
)vendors - the vendor_id line (e.g.
GenuineIntel
)models - the model name line (e.g.
Intel(R) Xeon(R) CPU E5-2690 0 @ 2.90GHz
)model_ids - the model line (e.g.
45
)families - the cpu family line (e.g.
6
)clockspeeds - the cpu MHz line (e.g.
2900.000
)cache_sizes - the cache size line (e.g.
20480 KB
)cpu_cores - the cpu cores line (e.g.
1
)apicid - the apicid line (e.g.
1
)stepping - the stepping line (e.g.
2
)address_sizes - the address sizes line (e.g.
40 bits physical, 48 bits virtual
)bugs - the bugs line (e.g.
cpu_meltdown spectre_v1 spectre_v2 spec_store_bypass l1tf mds swapgs taa itlb_multihit
)
