Kernel Naming
|
|
=============
|
|
|
|
The kernel NVR looks like, for example,
|
|
kernel-5.17.0-0.rc8.551acdc3c3d2.124.test.fc35. This string contains
|
|
information about the upstream release, a unique build number, and information
|
|
about the distribution the RPM was targeted for. An explanation of each of the
|
|
fields and how the fields are used in the kernel NVR, is below.
|
|
|
|
**SPECPACKAGE_NAME**: This is the name of the package. By default this is
|
|
'kernel', but a well-known variant is kernel-rt.
|
|
|
|
**SPECKVERSION**: This is the VERSION variable defined in the top-level linux
|
|
Makefile.
|
|
|
|
**SPECKPATCHLEVEL**: This is the PATCHLEVEL variable defined in the top-level
|
|
linux Makefile.
|
|
|
|
**SPECKSUBLEVEL**: This is the SUBLEVEL variable defined in the top-level linux
|
|
Makefile.
|
|
|
|
**UPSTREAMBUILD**: This is a representation of the upstream build information.
|
|
It includes the EXTRAVERSION variable (defined in the top-level Makefile) or
|
|
'rc0' if the tree is based on an a specific upstream release. If the tree is
|
|
not based on a specific "rc" release, this field also contains a git hash
|
|
reference to the top of tree commit.
|
|
|
|
**BUILD**: This is the RHEL_RELEASE variable defined in the top-level linux
|
|
Makefile.rhelver.
|
|
|
|
**DISTLOCALVERSION**: By default, this variable is set to ".test". This value can
|
|
be overriden by defining a string in redhat/localversion.
|
|
|
|
**DIST**: This is the dist release suffix used in the package release, eg.
|
|
.fc34 or .el9.
|
|
|
|
The kernel name is constructed as
|
|
|
|
$(SPECPACKAGE_NAME)-$(SPECKVERSION).$(SPECKPATCHLEVEL).$(SPECKSUBLEVEL)-$(UPSTREAMBUILD)$(BUILD)$(DISTLOCALVERSION)$(DIST)
|
|
|
|
In general, the kernel follows the Fedora Naming Guidelines, `https://fedoraproject.org/wiki/Packaging:Naming?rd=Packaging:NamingGuidelines <https://fedoraproject.org/wiki/Packaging:Naming?rd=Packaging:NamingGuidelines>`__.
