How to confirm Kernel is support 64bit CPU

Author: Che-Yuan Tu

從 32 位元升級到 64 位元,Linux Kernel 重編需注意的地方與部份 lib64xxx 需要升級

  • [結論] 參考設定下載
    • 今天編的 kernel 2.6.20 32 位元
    • lsi 學長之前在 Fedora Core 7 的 kernel 2.6.22 64 位元的 kernel config file.
  • 64位元 linux_kernel key point
    • x86 64 支援
    • highmem 支援
    • elf32 模擬支援
    • ia32 模擬支援

  • lib64xxx 視需求而安裝 (以Linux krg-server 2.6.20-krg為例)
    • lib64asound2 - ALSA library (64 bit)
    • lib64asound2-dev - ALSA library development files (64 bit)
    • lib64bz2-1.0 - high-quality block-sorting file compressor library - 64bit runtime
    • lib64bz2-dev - high-quality block-sorting file compressor library - 64bit development
    • lib64ffi4 - Foreign Function Interface library runtime (64bit)
    • lib64g2c0 - Runtime library for GNU Fortran 77 applications (64bit)
    • lib64gcc1 - GCC support library (64bit)
    • lib64gfortran1 - Runtime library for GNU Fortran applications (64bit)
    • lib64mudflap0 - GCC mudflap shared support libraries (64bit)
    • lib64ncurses5 - Shared libraries for terminal handling (64-bit)
    • lib64ncurses5-dev - Developer's libraries for ncurses (64-bit)
    • lib64objc1 - Runtime library for GNU Objective-C applications (64bit)
    • lib64readline5 - GNU readline and history libraries, run-time libraries (64-bit)
    • lib64readline5-dev - GNU readline and history libraries, development files (64-bit)
    • lib64ssp0 - GCC stack smashing protection library (64bit)
    • lib64stdc++6 - The GNU Standard C++ Library v3 (64bit)
    • lib64stdc++6-4.1-dbg - The GNU Standard C++ Library v3 (debugging files)
    • lib64z1 - compression library - 64 bit runtime
    • lib64z1-dev - compression library - 64 bit development
    • libc6-dev-amd64 - GNU C Library: 64bit Development Libraries for AMD64

  • 開啟 64 Support options for example
    #
    # Automatically generated make config: don't edit
    # Linux kernel version: 2.6.18-1.2257
    # Mon Jan 14 20:30:31 2008
    #
    CONFIG_X86_64=y
    CONFIG_64BIT=y
    CONFIG_X86=y
     
    
    # Executable file formats / Emulations
    #
    CONFIG_BINFMT_ELF=y
    CONFIG_BINFMT_MISC=m
    CONFIG_IA32_EMULATION=y
    CONFIG_IA32_AOUT=y
    CONFIG_COMPAT=y
    CONFIG_SYSVIPC_COMPAT=y
    
    

最後感謝阿德學長提供許多寶貴意見!!
