[-- Attachment #1 --] Hi, I just got 6GB of RAM for our ftp-server running -CURRENT. Usually, I would have upgraded to the latest current, built a kernel with PAE and see how far I get. However, machines with > 4GB need some tweaking with respect to KVA. However in the NOTES files there is not much how to set the KVA_PAGES. How much would I need? pae(4) mentions tuning(7), which does not tell anything about PAE issues. But pae(4) says, that there may be issues with kernel-modules. So here are my questions: - Do I need to include 'options PAE' somehow into the build of the kernel-modules in order to use them? Or is a pure static kernel the only option? - Where do I find documentation how to set my KVA and to which size to not run into problems. - pae(4) includes some other hints how to tune, but maybe there are other things to look at? - Maybe someone running a PAE enabled server with > 4GB can give some useful hints from experience? - I usually use a downtime to upgrade the OS. However, since the netperf merge is currently in progress, I assume it's not the ideal time, to upgrade a production machine right now, is it? Thanks and best regards, Daniel -- IRCnet: Mr-Spock - Soon I will be free, then hungry. - Daniel Lang * dl@leo.org * +49 89 289 18532 * http://www.leo.org/~dl/ [-- Attachment #2 --] 0s *H d0`1 0 + 0 *H 0 0#0 *H 0r1 0 UDE10UMuenchen1 0 U TUM1 0 U IN10URBG-Benutzer-CA10 *H ca@in.tum.de0 040423131558Z 050531000000Z0w1 0 UDE10UMuenchen1 0 U TUM1 0 U IN10U Daniel Lang1$0" *H daniel.lang@in.tum.de0"0 *H 0 W}%Iomp:+bA4W@UI|ܬ.!fD4C=F ց`٤{5d h: '&4M^O 7s z,>@݁</)>D"HoEIm{0o 5287iť1{mX2E ͧBQ 5e[3;-+|L-tY=?T ͒~ 00 U 0 0 U rUqBngȱ\X^f0U #06$9fG= ;ò fEmk0i1 0 UDE10UMuenchen1 0 U TUM1 0 U IN10 URBG-CA10 *H ca@in.tum.de0U 0 U %0++0U 0langd@in.tum.dedaniel.lang@in.tum.de langd@informatik.tu-muenchen.de%daniel.lang@informatik.tu-muenchen.delangd@cs.tum.edudaniel.lang@cs.tum.edu dl@leo.org0 U 0 0;U 40200.,*http://ca.in.tum.de/crls/g2/userca_crl.crl0 `HB0 `HB Dieses Zertifikat wurde ausgestellt fuer Daniel Lang von der RBG-Benutzer-CA (2.Generation), Fakultaet fuer Informatik der Technischen Universitaet Muenchen.06 `HB)'http://ca.in.tum.de/cgi-bin/userca-rev?02 `HB%#http://ca.in.tum.de/cgi-bin/ca-rev?0, `HB http://ca.in.tum.de/policies/0GU @0>0< +>eH0+0)+ http://ca.in.tum.de/policies/0 *H h[5BC1JkG[ūp+mZ#Ry6JkF]Oj_L\!
