## Standardized kernel package version and uname are composed as follows:
|
|
#
|
|
# A valid tag: [PREFIX-]<KERNEL_MAJVER>-<KERNEL_RELVER>[.<KERNEL_DIST>]
|
|
# uname -r: <KERNEL_MAJVER>-<KERNEL_RELVER>[.<KERNEL_DIST>][+<LOCALVER>]
|
|
# RPM NVR: kepnel[-<KERNEL_DIST>][-<LOCALVER>]-<KERNEL_MAJVER>-<KERNEL_RELVER>
|
|
# <NNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNN>-<VVVVVVVVVVVVV>-<RRRRRRRRRRRRR>
|
|
#
|
|
# Some NOTES about why we compose these string in above way:
|
|
# - Notice KERNEL_DIST is moved to N part of the RPM NVR, this is how TK3/TK4 release have been doing
|
|
# and that is correct because we need to distingush between kernel release streams. And there are
|
|
# things will break if we move it out of this part (mostly due to package name change).
|
|
# - RPM split the whole package name by '-', then recognize the right most part as R, second right
|
|
# most part is V, so KERNEL_MAJVER and KERNEL_RELVER can't contain '-'.
|
|
# - LOCALVER is commonly used to present variants of kernel, that is, using same kernel repo commit/version/tag,
|
|
# just built with a different config.
|
|
# A example is RPM pkg kernel-5.4.119-1 (uname 5.4.119-1) and kernel-debug-5.4.119-1 (uname 5.4.119-1+debug),
|
|
# the later one is same kernel built with more debug configs enabled. When kernel-5.4.119-1 run into unkown
|
|
# issues, kernel-debug-5.4.119-1 could be installed to do more diagnosis.
|
|
# - Notice LOCALVER is moved to "N" part of the RPM NVR, because adding to "V" or "R" part breaks kernel
|
|
# package versioning. A suffix, prefix or in-fix of "V" or "R" could cause the package or repo manager
|
|
# to make variants override each other, and fails the system unexpectly. For example, an debug kernel
|
|
# could be wrongly installed with a normal system wide package update, since the suffix made it had a
|
|
# high version number and it shares same Name with vanilla kernel.
|
|
# - Some old TK4 tag will have KERNEL_DIST as part of KERNEL_RELVER, we cover that too.
|
|
#
|
|
## More explanations of each field:
|
|
#
|
|
### PREFIX: <none>/release/x86/aarch64/oc/....
|
|
# - Could be some well-known string like "release", "x86", ..., could be used to make tags more distinguishable.
|
|
#
|
|
### KERNEL_MAJVER: <VERSION>.<PATCHLEVEL>.<SUBLEVEL>
|
|
# - It's the standdard upstream linux kernel release version, presents in kernel's root Makefile, eg:
|
|
# VERSION = 5
|
|
# PATCHLEVEL = 4
|
|
# SUBLEVEL = 203
|
|
# Which stands for kernel 5.4.203
|
|
#
|
|
### KERNEL_RELVER: [0.<SNAPSHOT>.][<EXTRAVERSION>.]<REL>
|
|
# - If starts with 0, indicates it's a snapshot, unofficial release. Else it must be a tagged release.
|
|
# The <SNAPSHOT> string is automatically generated using git commit as versioning base for untagged
|
|
# test builds.
|
|
# - If EXTRAVERSION is non-empty, it must present here.
|
|
# - REL is a custom release string, should be alphanums be splitted by '.'.
|
|
# eg. 0011, 0009.12, 0011.prerelease1, ...
|
|
# eg. 2207.1.1, 2207.1.2, ...
|
|
#
|
|
# NOTE: due to historical reason, in KERNEL_RELVER, it could contain '-', but the final generated string that will be used in
|
|
# spec file and uname will always be converted to contain '.' only, to comply the RPM NVR naming style, also make things cleaner.
|
|
#
|
|
### KERNEL_DIST: <none>/tks/tlinux4/stable/stream/...
|
|
# Indicates this is a special build kernel, will show up in RPM package name to distinguish different kernel release stream.
|
|
# Is configurable through the KDIST variable in dist/Makefile.
|
|
#
|
|
# NOTE: Due to historical reason, if KDIST is added as first part of KERNEL_RELVER's <REL> string, it will be move to tail.
|
|
# To make the KERNEL_RELVER part consistent between RPM name, tag and uname.
|
|
#
|
|
# Example:
|
|
# git describe --tag RPM uname -r
|
|
# 5.4.119-1-tlinux4-0007 kernel-tlinux4-5.4.119-1.0007 5.4.119-1.0007.tlinux4
|
|
# 5.4.119-1-tlinux4-0007-2-g884a77bf0ba6 kernel-tlinux4-5.4.119-0.20211115git1135ec008ef3.1.0007 5.4.119-0.20211115git1135ec008ef3.1.0007.tlinux4
|
|
# 5.4.119-1-tlinux4-0007.subrelease kernel-tlinux4-5.4.119-1.0007.subrelease 5.4.119-1.0007.subrelease.tlinux4
|
|
# 5.4.119-1-tlinux4-0007~rc1 kernel-tlinux4-5.4.119-1.0007~rc1 5.4.119-1.0007~rc1.tlinux4 (*)
|
|
#
|
|
# NOTE: Sometime TK4's release version may go backwards, it's a known issue we have to live with.
|
|
# TK4 used tag like 5.4.119-1-tlinux4-0007.prerelease to indicate a release candidate.
|
|
# You can check this with `rpmdev-vercmp`:
|
|
# $ rpmdev-vercmp 5.4.119-1-tlinux4-0007.prerelease 5.4.119-1-tlinux4-0007
|
|
# $ 5.4.119-1-tlinux4-0007.prerelease > 5.4.119-1-tlinux4-0007
|
|
# This means RPM thinks the release candidate is higher than the real release, to fix that,
|
|
# try use tilde symbol to indicate it's a RC.
