Updating kernel from source

The Red Hat Enterprise Linux kernel is custom-built by the Red Hat Enterprise Linux kernel team to ensure its integrity and compatibility with supported hardware.Before Red Hat releases a kernel, it must first pass a rigorous set of quality assurance tests.INSTALL /lib/firmware/mts_INSTALL /lib/firmware/mts_INSTALL /lib/firmware/mts_INSTALL /lib/firmware/edgeport/INSTALL /lib/firmware/edgeport/boot2INSTALL /lib/firmware/edgeport/INSTALL /lib/firmware/edgeport/down2INSTALL /lib/firmware/edgeport/down3INSTALL /lib/firmware/whiteheat_INSTALL /lib/firmware/INSTALL /lib/firmware/keyspan_pda/keyspan_INSTALL /lib/firmware/keyspan_pda/xircom_INSTALL /lib/firmware/cpia2/stv0672_vp4INSTALL /lib/firmware/yam/1200INSTALL /lib/firmware/yam/9600DEPMOD 4.10.1 sh ./arch/x86/boot/4.10.1 arch/x86/boot/bz Image \ "/boot"Then you can reboot you Linux OS and choose the new kernel in grub/grub2 entries to use the new Linux kernel.If it is not the default entry, you may use the grub2-select tool to change the default grub2 boot entry.

Stable kernel releases are based directly on Linus Torvalds' releases, and are released every week or so, depending on various external factors (time of year, available patches, maintainer workload, etc.).

The older a LTS kernel is, the less patches are applicable to it as many recent bugfixes are not relevant to older kernels.

However, the older a kernel is, the harder it is to backport the changes that are needed to be applied, due to the changes in the codebase.

In this post, we will use the example of building kernel 4.10.1 on Cent OS 7.

You need to install the tools needed depending on the default packages installed on your system. If it is reported more are needed/missing, you may install them accordingly.
