    Hi Suresh,<br>
    <br>
    We should keep the API consistent across platforms, that means if
    the 'memory' parameter is a 'string' in one platform we should be a
    string across all them.<br>
    <br>
    With this patch, we will have different results depend on arch,
    which make hard on how to expect from the output.<br>
    <br>
    For x86, we will have: 'cpus' as a dict and 'memory' as a number<br>
    {                                                                              
    <br>
     
    "cpus":{                                                                     
    <br>
       
    "offline":0,                                                               
    <br>
       
    "online":4                                                                 
    <br>
     
    },                                                                           
    <br>
     
    "memory":7933902848                                                          
    <br>
    }                                                                              
    <br>
    <br>
    For s390x, we will have 'cpus' as 'memory' as a dict.<br>
                                                                                   
    <br>
    {                                                                              
    <br>
     
    "cpus":{                                                                     
    <br>
       
    "shared":2,                                                                
    <br>
       
    "offline":2,                                                               
    <br>
       
    "dedicated":0,                                                             
    <br>
       
    "online":2                                                                 
    <br>
     
    },                                                                           
    <br>
     
    "memory":{                                                                   
    <br>
       
    "offline":2147483648,                                                      
    <br>
       
    "online":2147483648                                                        
    <br>
     
    },                                                                           
    <br>
     
    "virtualization":{                                                           
    <br>
       
    "lpar_name":"CSTLIN1",                                                     
    <br>
       
    "hypervisor":"PR/SM",                                                      
    <br>
       
    "lpar_number":55,                                                          
    <br>
       
    "hypervisor_vendor":"IBM"                                                  
    <br>
     
    }                                                                            
    <br>
    }                                                                              
    <br>
    <br>
    And for ppc, we will have 'cpus' and 'memory' as a number.<br>
    {                                                                              
    <br>
      "cpus":&lt;cpu
    count&gt;,                                                          
    <br>
     
    "memory":&lt;memory&gt;                                                            
    <br>
    }  <br>
    <br>
    My suggestion is to user dict for 'memory' and 'cpus' for all both
    platforms.<br>
    <br>
    <b>For 'memory':</b><br>
    <br>
    memory: {online: ..., offline:...}<br>
    <br>
    By 'online' memory, do you mean the memory current in the host? If
    so, we can use those 2 values for all the platforms and assume to
    total memory as online and 0 (zero) for offline memory for x86 and
    ppc.<br>
    <br>
    <b>For 'cpus':</b><br>
    <br>
    cpus: {online: ..., offline: ..., shared:..., dedicated:...}<br>
    <br>
    shared and dedicated only make sense for s390x, but online and
    offline make sense for all the platforms so we can use them overall.
    <br>
    <br>
    What do you think about it?<br>
    <br>
    Regards,<br>

As per RFC mail thread -
     [Kimchi-devel] RFC - #728 - Processor Info in s390 architecture
this patch set adds functionality in back-end to add
architecture, and host name(for all architecture),
split CPUs to online and offline(x86, s390x),
additional virtualization details(for s390x)

Note: Subsequent patch set for UI changes will follow
      to accommodate these changes

Suresh Babu Angadi (1):
  Fix for issue 728: processor info displays blank for system z     this
    patch set also adds additional capability:     retrieving
    architecture and host name (for all architecture)     split CPUs to
    show online and offline cpus(for x86 and s390x)     split memory to
    show online and offline memory(for s390x)     additional
    virtualization details(for s390x):         virtualization will have
    hypervisor details and lpar details
