My main and first ARM platform i compile for is an Genesi Efika Smartbook, it made me realize how much of an plague .deb systems are..
also been messing more around with the Jolla phone i got, i must say its a quite good compiler..
Ever thought about chaining a couple of android phones to a compiler cluster?
Anyhow the qemu problem seems to be that it uses one core by default. I took a look at the qemu-binfmt: http://pastebin.com/yrLuuAKL
and so far i could figure out the binary does not get any cpu number info, so lets put an -smp 8 there.. wasn't sure whereto but i think i figured it out.
So currently. i have to assume qemu uses only one core in snail speed. (htop, may be right) i'm too lazy to do any speed tests but lets put an -smp 8
maybe, here? if [ $cpu != "arm" -a -x "/usr/bin/qemu-static-arm-binfmt -smp 8" ] ; aaannd..
I get: chroot: failed to run command ?/bin/bash?: Exec format error. So.. where to feed it.
Oh and i been getting on a FX-8320 near target system performance,
but with those make CFLAGS: "-O2 -pipe -march=armv7-a -mfpu=neon -funsafe-math-optimizations -mfloat-abi=hard"
