Possibly, but then again maybe not. The reason I say this is that Linux doesn't care if it is running on an IFL or a CP does it? The change would (most likely) have to be in hardware and z/VM. Since z/VM 5.3 can already tell a z/OS guest that there is a virtual zIIP and/or zAAP available, "some" of the groundwork is there. As for the micro code, there would probably need changes (see hardware above). Again, this is just a "pie in the sky" idea. As for going to IBM, mentioning POC etc, that requires time, and paperwork both of which translate to real dollars in management's eyes. As to the comment that another CP is already needed, that could be why work is being moved off of z/OS in the first place. Again, this is all a hypothetical question.

I would think that this is a 'trade secret' for IBM and one they would prefer to control/license as they are with zIIP for z/OS workloads (zAAP appears to be a little more generic). Ken Porowski -----Original Message----- Ted MacNEIL > can't see what would prevent a mix of IFL+n*zAAP+m*zIIP LPAR from running linux How about: it's not supported -- there is no code in zLINUX to (a) recognise zAAPs & zIIPs, and (b) run anything on it. >(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. ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
