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":<cpu
count>,
<br>
"memory":<memory>
<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>

Hi Aline,<br>
Yes, I agree with your suggestion. Only s390x will have online and
offline memory, for x86 and ppc - it is total memory in host, will
keep offline memory as zero for x86 and ppc.<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>
</blockquote>
Agreed. I am currently using lscpu o/p to fetch total cpus and
difference of total cpus and online cpus(fetched using psutil) will
be taken as offline cpus.<br>
I searched in google for sample lscpu o/p in ppc, it has CPU(s)
field in lscpu which is the total cpu count. Please let me know if
it doesn't provide this information in lscpu, otherwise we are good
here.<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
Test Cases Executed:
====================
1) On x86 machine:
curl -k -u suresh -H "Content-Type: application/json" -H "Accept: application/json" -X GET '<a moz-do-not-send="true" class="moz-txt-link-freetext" href="https://127.0.0.1:8001/plugins/gingerbase/host">https://127.0.0.1:8001/plugins/gingerbase/host</a>'
{
"os_distro":"Fedora",
"cpus":{
"offline":0,
"online":4
},
"cpu_model":"Intel(R) Core(TM) i5-3320M CPU @ 2.60GHz",
"os_version":"21",
"host":"localhost.localdomain",
"os_codename":"Twenty One",
"architecture":"x86_64",
"memory":7933902848
}
2) On s390x machine:
curl -k -u root -H "Content-Type: application/json" -H "Accept: application/json" -X GET '<a moz-do-not-send="true" class="moz-txt-link-freetext" href="https://127.0.0.1:8001/plugins/gingerbase/host">https://127.0.0.1:8001/plugins/gingerbase/host</a>'
{
"os_distro":"KVM for IBM z Systems",
"cpus":{
"shared":2,
"offline":2,
"dedicated":0,
"online":2
},
"cpu_model":"IBM/2827/743 H43",
"os_version":"1.1.1",
"host":"zfwcec103",
"os_codename":"Z",
"architecture":"s390x",
"memory":{
"offline":2147483648,
"online":2147483648
},
"virtualization":{
"lpar_name":"CSTLIN1",
"hypervisor":"PR/SM",
"lpar_number":55,
"hypervisor_vendor":"IBM"
}
}
3) For Power(Expected Output):
{
"os_distro":<os distro>,
"cpus":<cpu count>,
"cpu_model":<cpu model>,
"os_version":<os version>,
"host":<host name>,
"os_codename":<os codename>,
"architecture":"ppc",
"memory":<memory>
}
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
