customize CFLAG with /etc/mk.conf
Hi, Is that possible to modify CFLAG for port installed software ? I read `man mk.conf' found there's no CFLAGS or CXXFLAG entries , even though i tried to put `CFLAG += -O3 -march=i686' into that file , but ports doesn't recognize it. Just want to optimize ports software , during compilation of kernel , i'd comment them out. Does anyone has any ideas ?

Re: customize CFLAG with /etc/mk.conf
Thanks Jacob , I just want to make some graphic software faster. Cause i have a core2 cpu , supports mmx code and some other features , i'm trying to see if it really helps with those compiler flags.

[SOLVED] Re: customize CFLAG with /etc/mk.conf
First of all , thanks for all your experiences ;-) Forgive me , i didn't response to all your mail. So let me do a summary , after collection all you mails: I) generating CPU featured assemble takes longer time , also risks in creating wrong code II) customize compiler flag on OpenBSD doesn't values so much as what we costs to achieve it. Thanks again ! Ivan Nudzik wrote: Aaron, I built 3.7 base + OpenVPN for VPN gateway with custom CFLAGS/LDFLAGS and it worked well for years, even with such aggressive flags as CFLAGS="-O3 -march=c3 -mmmx -m3dnow -fomit-frame-pointer" and LDFLAGS="-Wl,-z,combreloc -Wl,-O2 -Wl,--sort-common -Wl,--enable-new-dtags". But build was broken and I must to fix many things in OpenBSD makefiles, to get binaries done. Such LDFLAGS significantly speedups application loading, cause it's doing the same things as prelink utility, but it link time. CFLAGS helps me speedup C3 500MHz router device as about 20-30%, but it was synthetic measurement on nbench built with and without CLFAGS. Kernel build was also forced for such CFLAGS and no stability issue and subjectively more speedy. I've read about that , e.g kernel avoid intel MMX instructions , cause it may cause interrupts (handle lots of register together to combine a bigger register) It was few years ago, when I've had mood to compile everything with all CPU features on. ;-) Yeah , i'm so interesting with CPU features on my Linux right now , like what you did a few years ago ;-) Looking at this concrete OpenBSD build my summary is that it took me more than 20h to build it and speedups was not such significant, comparing that it should took an about 1h to do the same functionality with release binaries only bit slow. And two other things to keep on mind: nowadays x86 CPUs has very heuristic instruction handling/prefetching so it will not speedup as much with custom CFLAGS; OpenBSD still use gcc 3.3.5 which can't do as good optimization for new CPUs as to loose time with custom flags build. And many makefiles in OpenBSD base don't handle CFLAGS/LDFLAGS correctly. The last time I tried it (about 1/2y. ago), I made only kernel with custom flags (for kernel it is COPTS variable if I remember right). Rest of system didn't build and I didn't had a time to bother with broken makefiles. So if you don't want to do HPC, don't loose time with custom flags. I if you want to do HPC, choose other operating system, cause OpenBSD strengths are other. I take your suggestion , ain't gonna waste time playing gcc's flags. -- Best Regards, Aaron Lewis - PGP: 0x4A6D32A0 FingerPrint EA63 26B2 6C52 72EA A4A5 EB6B BDFE 35B0 4A6D 32A0 irc: A4r0n on freenode

Generic Discuss about CPU resource scheduling
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hi, I'm reading Operating System Concepts (7th Edition) , Written by Abraham , Peter & Greg. In chapter 5.3 , it talks about a schedule algorithm: SJF SJF means shortest jobs schedules firstly. To compare different process , thy use a process running time. e.g P1 takes 6 secs to run P2 takes 3 seconds P3 takes 10 secs Then we should put those tasks in array like this: P2 => P1 => P3 That looks much reasonable , but my question is , how does an OS know that a process will takes longer time to finish its life ? I think it's impossible to let OS know exactly how long a process will take to run. So far in my experience , i think there's a few ways to compare Process running time: Forgive me if i have a poor experience on OS ;-) I) Number of Loops in a Program , can be detected by compiler As long as you have any loops , you are slower than any straight ahead program II) Length of Program , longer code takes longer time sometimes , not a good way.

So .. if i use a single file , i'm just worrying that if my file size keep growing , will there be a problem ? E.g: It's like the ISO image file , once created , if you want to add new files. You can't just simply resize it , but only create a new one , right ? I want to use the whole disk just in case of that problem.
