    101         <para>
    102           If a Linux distribution on LoongArch provides a kernel older than
    103           &min-kernel;, it indicates the distribution is using a preliminary
    104           version of the kernel ABI.  The preliminary draft was rejected by
    105           the kernel maintainers and it's fundamentally incompatible with
    106           the packages we will built for LFS.  Such <quote>old-world</quote>
    107           distributions (for example, Loongnix) cannot be used as a host
    108           distro for building LFS.
    109         </para>
    110 
    111         <para>
    112           Do not attempt to update the kernel to &min-kernel; or later on
    113           a old-world distro because doing so will cause a boot failure.
    114           Use a <quote>new-world</quote> distribution providing Linux Kernel
    115           &min-kernel; or newer instead.  You may need to contact the vendor
    116           of your hardware to get a firmware update for booting a new-world
    117           distribution because the boot protocol of LoongArch is stabilized
    118           after the launch of the early LoongArch hardwares.

     96      <xref linkend="chapter-building-system"/>, so the workarounds for
     97      older kernels are not enabled and the compiled
     98      <application>glibc</application> is slightly faster and smaller.
     99      As at June 2023, &min-kernel; is the oldest kernel release still
     100      supported by the kernel developers.</para>
     101
     102      <para>If the host kernel is earlier than &min-kernel; you will need to replace
     103      the kernel with a more up-to-date version. There are two ways
     104      you can go about this. First, see if your Linux vendor provides a &min-kernel;
     105      or later kernel package. If so, you may wish to install it. If your
     106      vendor doesn't offer an acceptable kernel package, or you would prefer not to
     107      install it, you can compile a kernel yourself. Instructions for
     108      compiling the kernel and configuring the boot loader (assuming the host
     109      uses GRUB) are located in <xref linkend="chapter-bootable"/>.</para>

    154       <para>
    155         <parameter>--removable</parameter> may seem strange here.  The UEFI
    156         firmware searches EFI executables for boot loaders in a hardcoded
    157         path, <filename>EFI/BOOT/BOOTLOONGARCH64.EFI</filename> in the ESP, and other
    158         boot loader paths listed in the EFI variables.  We've not installed
    159         the utilities for manipulating EFI variables so we need to install
    160         the EFI executable into the hardcoded path.  The hardcoded path is
    161         usually used by removable devices (for example, USB thumb devices)
    162         so the <command>grub-install</command> option for this purpose is
    163         named <parameter>--removable</parameter>.
    164       </para>
    165       <para>
    166         UEFI implementation usually prefers the boot loaders with paths
    167         recorded in an EFI variable, to the boot loader with the hardcoded
    168         search path.  You may need to invoke the boot device selection menu
    169         or setting interface of your EFI firmware on next boot to explicitly
    170         select the bootloader.
    171       </para>
    172       <para>
    173         Some UEFI implementation may completely skip the hardcoded path if
    174         there are other boot loaders in the same hard drive with paths
    175         recorded in an EFI variable.  Then you need to create an EFI
    176         variable for the newly installed boot loader.  Install
    177         <ulink url="&blfs-book;postlfs/efibootmgr.html">efibootmgr</ulink>,
    178         then run the following commands:

    23 <para>The build that results from this LFS edition is a
    24 <quote>pure</quote> lp64d system. That is, it supports executables with
    25 the lp64d ABI
     23<para>The gain from building on a 64-bit system, as
     24compared to a 32-bit system, is minimal.
     25For example, in a test build of LFS-9.1 on a Core i7-4790 CPU based system,
     26using 4 cores, the following statistics were measured:</para>

     28<screen><computeroutput>Architecture Build Time     Build Size
     2932-bit       239.9 minutes  3.6 GB
     3064-bit       233.2 minutes  4.4 GB</computeroutput></screen>

     32<para>As you can see, on the same hardware, the 64-bit build is only 3% faster
     33(and 22% larger) than the 32-bit build. If you plan to use LFS as a LAMP
     34server, or a firewall, a 32-bit CPU may be good enough. On the other
     35hand, several packages in BLFS now need more than 4 GB of RAM to be built
     36and/or to run; if you plan to use LFS as a desktop, the LFS authors
     37recommend building a 64-bit system.</para>

     39<para>The default 64-bit build that results from LFS is a
     40<quote>pure</quote> 64-bit system. That is, it supports 64-bit executables
    2641only. Building a <quote>multi-lib</quote> system requires compiling many
    27 applications multiple times, once for each ABI to be supported.
     42applications twice, once for a 32-bit system and once for a 64-bit system.
    2843This is not directly supported in LFS because it would interfere with the
