CuriouscraigIs the Wifi N USB adapter good for broadcasting wifi if you use PFSense when using a Minnowboard?03:41

tellendilhey, is there a place where I can find the set of assembly instructions for the minnowboard Max ?20:21
*** givemefive911 <givemefive911!~Thunderbi@75-17-224-103.lightspeed.dllstx.sbcglobal.net> has joined #minnowboard20:22
tellendilOk... the minnowboard seems to segfault on vstmxcsr instruction :/20:27
tbrI'd expect intel to have rather exhaustive documentation, just look up the CPU20:30
tellendilokay20:33
tellendilcould somebody confirm that the processor does not support avx ? I'm a bit lost20:43
ahollercat /proc/cpuinfo20:51
tellendilaholler, yes I know... but I just can't get some programs work while compiling on another host -_- and I don't see what I did do wrong20:55
aholleryou'ce asked for avx, does it appear there?20:55
ahollerif not, that's the confirmation you've asked for20:56
tellendilno, and I added -mno-avx and -mno-avx2 but I still get "vstmxcsr" instructions... which in the spec is avx x) well ok20:56
aholleryou should not have to add -mno-avx.20:57
tellendilaholler, why ?20:58
ahollerif so, you've choosen the wrong cpu-type20:58
aholler(march)20:59
tellendilmarch=silvermont on gcc 4.9.2...right ?20:59
ahollerno idea20:59
ahollerwhy you're not compiling it without any march first?21:00
tellendilbecause I'd like top have it optimizer for my cpu21:01
ahollerpremature optimization is the root of all evil. first compile it without rice flags, test it, than add them. so you know exactly your flags are wrong.  not the other way around.21:04
ahollers/rice/ricer/21:04
tellendilok, now even with only "-march=x86_64" it segfaults....21:32
ahollerand you've compiled all libs with that too?21:33
ahollerjust changing the flags for the programm in question doesn't work if e.g. glibc and other stuff are still compiled with the wrong flags21:34
tellendilmmh right I might have forgotten a part ...21:37
tellendilI'll retry with everything21:37
tellendil-march=atom should be safe right ?21:37
ahollerno idea ;)21:37
ahollernever looked at the flags for these cpus21:38
