I am currently looking at the HugePage support feature and whether it can help us at our site. But I hit a roadblock that someone out there may be able to help me with.
In the doc I have found (both from RH and a collection of other presentations on the web), I have found how to set the /proc/sys/vm/nr_hugepages value with sysctl with no problem. But my concern is with the next bit of information concerning whether the hardware has large page support and if not, how do I enable that support. When I issue cat /proc/cpuinfo, we do not have the "edat" value set in features (page 26 in http://zjournal.tcipubs.com/issues/zJ.DEC-JAN09.pdf). We have two z196s with zVM 6.1 running zLinux guests using RHEL 5.6 (2.6.18-238.9.1.el5). Can anyone point me to how to get the feature "edat" turned on and where documentation on this may be located?
