How remove the commit ID from kernel release version?

riccardo_cavedo — Tue, 28 May 2019 09:01:57 GMT

Good mornig,

Currently, I'm making a patch to the kernel but every time that create it the version is (for instance) 4.9.11-1.0.0+gc37aab8

How can remove the commit ID from the version?

I'm using i.MX Yocto Project Community BSP recipe layers (imx-morty) plus my meta layer where I added a recipe linux-imx_4.9.11.bbappend with SRC_URI that links to a specific commit ID of kernel.

Thank in advance for the help.

Riccardo

Hello Riccardo,

Thee kernel version string is built after some variables that you should be able to edit. The top Makefile should have the version and other variables listed but I would recommend being careful.

You can set the next 2 kernel variables:

CONFIG_LOCALVERSION=""
CONFIG_LOCALVERSION_AUTO=n

In your kernel config somewhere, I used a config snippet (I called it version.cfg but it does not matter). In the LOCALVERSION string you can also put your own postfix string which will be appended to the version.

Hi Riccardo Cavedon
Can you please share the steps that you have followed to create patch and which lines you have added to the .bbappend file.

To Create and add patch in yocto one can refer this link.

gusarambula‌ and henrideveer‌ thank you for the suggestions.

I've found the solution with the suggestion of henrideveer‌ and an additional modify.

The include file:

meta-freescale/recipes-kernel/linux/linux-imx.inc

has the option:

SCMVERSION ?= "y"‍‍

changing "y" with "n" the string with commit ID is removed.

So my append recipe has become:

EXTRAPATHS_prepend := "${THISDIR}/${PN}:"

LIC_FILES_CHKSUM = "file://${COMMON_LICENSE_DIR}/MIT;md5=0835ade698e0bcf8506ecda2f7b4f302"

SRC_URI = "git://<my_kernel_repo"
SRCREV = "1111111111111111111111111"
#SRCREV = "${AUTOREV}"

# Remove from the kernel version the additional string with commid ID of linux-imx repository
SCMVERSION = "n"‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Moreover, the defconfig of kernel has to be:

CONFIG_LOCALVERSION=""
CONFIG_LOCALVERSION_AUTO=n
