Please refer to 'man procfs(5)' for further information about the '/proc/cpuinfo' file, that is the source of the information provided by this class. The 'man lscpu(1)' also has information about a program that uses the '/proc/cpuinfo' file. Using this class one can obtain the number of CPUs in a system: >>> cpus = procfs.cpuinfo() >>> print cpus.nr_cpus 4 It is also possible to figure out aspects of the CPU topology, such as how many CPU physical sockets exists, i.e. groups of CPUs sharing components such as CPU memory caches: >>> print len(cpus.sockets) 1 Additionally dictionary with information common to all CPUs in the system is available: >>> print cpus["model name"] Intel(R) Core(TM) i7-3667U CPU @ 2.00GHz >>> print cpus["cache size"] 4096 KB >>> � /proc/cpuinfoc C s i | _ d| _g | _| j|� d S )Nr )�tagsr� �socketsr� )r+ �filenamer r r r- . s zcpuinfo.__init__c C s | j |j� S )N)r� �lower)r+ rr r r r r0 4 s zcpuinfo.__getitem__c C s t | jj� �S )N)r1 r� r2 )r+ r r r r2 7 s z cpuinfo.keysc C s t | jj� �S )N)r1 r� r3 )r+ r r r r3 : s zcpuinfo.valuesc C s | j S )N)r� )r+ r r r r5 = s z cpuinfo.itemsc C s( t |���}x�|j� D ]�}|j� }|s&q|jd�}|d j� j� }|dkrX| jd7 _qt� rv|dkrv| jd7 _q|dkr�q|d j� | j|< |dkr| j| }|| jkr| jj |� qW W d Q R X | jr�t | j�p�| jd| jkr�t | jd �p�d | _ d | jk�rt | jd ��pd| j | _ d S ) NrX r r% r z cpu numberzcore idz physical idZsiblingsz cpu cores)r8 rY r r: r� r� r r� r� rI r= r?

Can be used to figure out which processes have an library mapped, etc. The 'perm' member can be used to figure out executable mmaps, i.e. libraries. The 'vm_start' and 'vm_end' in turn can be used when trying to resolve processor instruction pointer addresses to a symbol name in a library. c C s� |d j � }dd� |d j d�D �\| _| _|d | _t|d d�| _|d j d �\| _| _t|d �| _t |�d kr�|d | _ nd | _ i | _ x^|dd � D ]N}|j � }|d d d � j � }yt|d �| j |< W q� || j |< Y q�X q�W d S ) Nr c S s g | ]}t |d ��qS )r )r? )r� r r r r r� j s z&smaps_lib.__init__.<locals>.<listcomp>�-r r r rF rX r � rg ) r: �vm_startZvm_endZpermsr? �offset�major�minor�inoder= r[ r� r� )r+ �linesr. rZ �tagr r r r- h s" zsmaps_lib.__init__c C s | j |j� S )N)r� r� )r+ rr r r r r0 } s zsmaps_lib.__getitem__c C s t | jj� �S )N)r1 r� r2 )r+ r r r r2 � s zsmaps_lib.keysc C s t | jj� �S )N)r1 r� r3 )r+ r r r r3 � s zsmaps_lib.valuesc C s | j S )N)r� )r+ r r r r5 � s zsmaps_lib.itemsN) rL rM rN rO r- r0 r2 r3 r5 r r r r r� \ s r� c @ s@ e Zd ZdZdd� Zdd� Zdd� Zdd � Zd d � Zd d � Z dS )�smapsa~ List of libraries mapped by a process.
