The short answer is because IBM is _not_ a non-profit corporation. The longer answer involves the costs to IBM of supporting older platforms versus the income those platforms generate.Or was the question retorical?
But wait.. The latest developerworks linux stream does not contains such restriction. The only one I see in ... http://www.ibm.com/developerworks/linux/linux390/development_recommended.html .. is that gathering fcp statistics requires a z9 or better. And they support the whole line of z hardware already. So it does not seem to be an IBM decision ! So the only restriction I can see here is one imposed by Novell (by forcing a -mtune or -mcpu=z9 at compile time from what I could gather).. What does Novell have to gain by restricting which z machine SLES 11 may run on ? Restricting to z/Arch (no 31 bit) was already, IMHO, a bad enough restriction.. But cutting itself from its z800/z900/z890/z990 customer base ? And personally, in those trouble days where a lot of businesses have indefinitely postponed hardware upgrades, I find imposing such arbitrary restriction to be very counter-productive. --Ivan ---------------------------------------------------------------------- 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
