How about: it's not supported -- there is no code in zLINUX to (a) recognise zAAPs
& zIIPs, and (b) run anything on it.
How about : It's linux, and the support there is is what people coding
linux code put in it. So yes.. at this particular point in time, you are
correct.
(unless, again, there is too much stuff stripped from the zAAPs & zIIPs that
would prevent it from
running general purpose threads).
There is -- that's the whole point.
Not IPLable.
Only designed for specific purposes under z/OS -- no othe zSoftWare supports
them.
"designed" is one thing.. usable is another. S/390 wasn't "designed" for
linux - but it works nonetheless
"support" for z/OS is what IBM put in there.
"support" for linux in general is what people put in it (eg: linux
"supports" the xbox)
"support" for commercial distribution of linux and/or any other software
(proprietary or not) is what they decree (eg: oracle doesn't "support"
running on debian - although there is no reason it shouldn't work).
Of course, if there is no documentation (at least none without signing
an NDA), if you can't SIGP the thing to tell it to start doing some
stuff or if it has a whole different ISA altogether, then there are of
course no way to dispatch any kind of work on it (aside from having the
z[IIP][AAP]s attached to z/OS to run stuff such as the custom jvm).
But I was merely putting my grain of salt on the "zLinux can't run on
z[IIP][AAP] for the same reason z/OS can't run on an IFL" (which I
believe was an incorrect statement) - then subsequently started on a
more speculative branch.
But of course, at the present time, it just won't work.
