  1. funtoo install illegal instruction

    in Installation Help

    Posted

     

    I did some research, mmxext is a part of mmx hence applied automatically and I think I need to pass more CFLAGS. I restarted my build again with below flags.

     

    CFLAGS="-march=broadwell -mabm -mno-adx -mno-aes -mno-avx -mno-avx2 -mno-bmi -mno-bmi2 -mno-f16c -mno-fma -mno-xsave -mno-xsaveopt -O2 -pipe"
    CXXFLAGS="${CFLAGS}"
    FFLAGS="${CFLAGS}"
    FCFLAGS="${CFLAGS}"
     
    CPU_FLAGS_X86="mmx mmxext popcnt sse sse2 sse3 sse4_1 sse4_2 ssse3"

     

    Build was complete and problem was resolved. Please mark as resolved and add the tag Metro?

    in Installation Help

    Posted

    I told Metro (inserted cp commands in steps/unpack.spec file) to copy my customized make.defaults file to overwrite in intel64-broadwell directory just after git sync command. All went well, stage3 was built successfully with my customized CPU flags but 1 problem happened. Somehow 1 flag extra was automatically added.

     

    What I told Metro:

    "mmx popcnt sse sse2 sse4_1 sse4_2 ssse3"

     

    What came out in build.json:

    "mmx popcnt sse sse2 sse4_1 sse4_2 ssse3 mmxext"

     

    Please suggest. What am I missing?

    I was reading the metro etc files. From common.conf it is obvious that Metro uses the path I stated above. I going to make changes and will share the results.

    I need to make some corrections on what I said here. Metro doesn't use running system's portage infrastructure. Metro downloads fresh portage snapshot and extracts it into working directory as specified in ~/.metro. Changes have to be made there, for instance:

     

    /var/tmp/metro/work/funtoo-stable/stage1-intel64-broadwell-funtoo-stable-2016-12-02/usr/portage/profiles/funtoo/1.0/linux-gnu/arch/x86-64bit/subarch/intel64-broadwell

     

    In that case re-running emerge --sync would be harmless as well.

    Thank you Oleg. You have determined the root cause. My last question is, how can I tell Metro to use specific flags? I think here, right?

    ok, your laptop cpu maybe not supporting all cpu instructions that is in CPU_X86_FLAGS for broadwell subarch. Intel is known of limiting lower end (or mobile) CPU's with instructions. For example your cpu does not support aes. While you are able to build in linode vps (likely it supports all instructions on hardware level) you will not be able to install on laptop. Examine instructions in /proc/cpuinfo

    cat /proc/cpuinfo | egrep "(model name|flags)"

    how did you build you broadwell stage? steps. is this on bare metal or  in virtual machine?

    I used metro remote build guide. Followed steps in funtoo.org/Metro. Here is my resultant directory structure.

    (Note: I have restarted the metro build, although I know that result will be the same)

     

    I built this on a VPS on Linode. Linode uses KVM. I am using funtoo on my VPS.

  8. funtoo install illegal instruction

    in Installation Help

    Posted

    Hi,

     

    I am trying to install funtoo on my chromebook. I have Intel Celeron 3215.

     

    I am also running funtoo on my Linode. I noticed that funtoo wasn't providing the broadwell stage3 tarballs so I decided to use Metro and build a broadwell tarball. (I already tried to use haswell tarball, same problem "Illegal Instruction").

     

    Once my broadwell tarball was ready I decided to use that one. I am getting the same error on that one too ("Illegal Instruction"). Did my Metro built tarball came out wrong? Please help.
