Re: OpenBSD 4.8's bsd.mp doesn't detect 4GB Memory
Just for the records, I'm running my main OpenBSD on a P3-M 700MHz with 256M. With XFCE it works fine, and, as I understand from my linux experience, to run comfortably with KDE4 you today need something abobe 512M. As it was said, in OpenBSD memory evacuation works so pretty good that, in order to use such a machine profitably, it's just matter of using less appz at the same time or a right mix of GUI and CLI ones. There is just one doubt that I have about the need of more memory for machines which are not heavy servers or multimedia developing ones: BROWSING. Just open a whatever firefox and keep on opening tabs, my 256M will at best start swapping after 7-9 concurrent tabs. With the heavy technologies (java, php, etc.) today embedded in web pages and with the growth rate of such trends (i.e. people like those developing chromium os who would like to put the entire world into a browser), I expect the web browser be the very next desktop memory hog for the years to come. Here's why, today, bigmem is not essential for me but, I think, will maybe be in 2-3 years from now.

Sure, your car can do 230 kph, but how often do you ever get over 150? Unless you're running a very busy database server or a crazy web server, I don't think you'll ever need much above 2GB. I have 2GB in most of my i386 and amd64 laptops and servers. None of my machines ever touch the swap. In fact, most of the time I have 50% FREE RAM. On my development laptop I typically run a Seamonkey Browser with 50 tabs and Mail (400MB), about 20 terminals (half of which are SSHed to remote machines), Inkscape, Gimp, Postgresql locally for dev, ruby-sinatra, etc. and I've never been over 1.2GB. I do run cwm as my window manager. So lets say for shits and giggles that you're running KDE or something bloated like that, then maybe you'll use another gig. So what, you're still under 3GB. Save yourself time and headaches and just run OpenBSD stable or snapshots. Compiling kernels is a waste of time when you're doing it for performance reasons. I used to do this shit about 8 years ago just to eek out a little more performance, so I thought. I was also coming from Linux/FreeBSD to OpenBSD at that time. I finally realized that my time is better spent doing other things. Now I run OpenBSD exclusively on all four of my systems and my life is easy. One last thing: when developers say don't do something, they know best so listen. Compiling in BIGMEM is bad if they told you no.

Here is a PR I submitted not to long ago that was immediately closed because it was based on a bigmem kernel: http://cvs.openbsd.org/cgi-bin/query-pr-wrapper?full=yesnumbers=6453 At the bottom of this lengthy bug report is the response of the dev who closed it.

OpenBSD 4.8's bsd.mp doesn't detect 4GB Memory
Hi guys. Recently I installed OpenBSD 4.8 and found out that it can't detect 4GB memory on my amd64 box. From the output of dmesg I can see it detects all the memory hardware (4x1G memory bars). Yet it can only use about 3.5G of them, like an i386 kernel does. I've googled the issue and some say one has to 'config' the default kernel (i.e., bsd.mp). But I am not very sure that I know how to do that... My question is: Is there anything I can do to make bsd.mp detect all the 4G memory on my amd64? There must be some way... I think. Many Thanks! -- When you are right be logical, when you are wrong be-fuddle.
