# kpatch-build(1)

build script

## NAME

kpatch-build - build script

## SYNOPSIS

kpatch-build \[options\] \<patch file\>

## DESCRIPTION

This script takes a patch based on the version of the kernel currently running and creates a kernel module that will replace modified functions in the kernel such that the patched code takes effect.

## OPTIONS

\-h\|--help\
    Show this help message

\-a\|--archversion\
    Specify the kernel arch version

\-r\|--sourcerpm\
    Specify kernel source RPM

\-s\|--sourcedir\
    Specify kernel source directory

\-c\|--config\
    Specify kernel config file

\-v\|--vmlinux\
    Specify original vmlinux

\-j\|--jobs\
    Specify the number of make jobs

\-t\|--target\
    Specify custom kernel build targets

\-n\|--name\
    Specify the name of the kpatch module

\-o\|--output\
    Specify output folder

\-d\|--debug\
    Keep scratch files in /tmp\
    (can be specified multiple times)

\--oot-module\
    Enable patching out-of-tree module,\
    specify current version of module

\--oot-module-src\
    Specify out-of-tree module source directory

\-R\|--non-replace\
    Disable replace flag of KLP\
    (replace is on by default)

\--skip-cleanup\
    Skip post-build cleanup

\--skip-compiler-check\
    Skips check that ensures that the system compiler version and\
    the compiler version that built the kernel match.  Skipping this\
    check is not recommended, but is useful if the exact compiler\
    version is not available or is not easily installed. Use\
    only when confident that the two versions of compiler output\
    identical objects for a given target.  Otherwise, use of\
    this option might result in unexpected changed objects\
    being detected.
