Steve,
You might be able to tell with "hyptop" under Linux, from the "man"
pages, the first line shows:
CPU TYPES
Depending on the hypervisor different CPU types are supported.
These CPU types can be selected either interactively or with the
"--cpu_types" command line option. The calculation of the CPU data only
uses CPUs of the specified types.
On LPAR the following CPU types are supported:
'IFL' - Integrated Facility for Linux
'CP' - CP processor type
'UN' - Unspecified processor type (other than CP or IFL)
NOTE: It is possible that on older machines also IFLs are shown as
CPs. On z/VM currently only the processor type 'UN' is available.

Please respond to
Linux on 390 Port

I have installed zVm with zLinux under it on a System z Lpar with IFL
processors before. I could verify that the IFLs were being used with zvm
commands.
With this one, I know we have an IFL that has been dedicated to this Lpar.
I was just curious if there are messages or commands within the zLinux
environment that verified that it is now using an IFL processor. A command
or a message would be helpful. If not, no worries.
Thanks.
