Walkthrough

Updated the kernel version for the collabora branch in the Genio family configuration from 6.14 to 6.18 by modifying the KERNEL_MAJOR_MINOR variable assignment. This is a straightforward version bump with no logic or control flow modifications.

🐰 From 6.14 up we hop so fast,
To 6.18, a kernel unsurpassed!
The Genio board now wears new threads,
With collabora's blessing, forward we tread! 🚀

Learning: In the Armbian build system, for recurring maintenance tasks like kernel version bumping, TODO comments should use generic version formats (e.g., "MAJOR.MINOR-rc1") rather than specific version numbers (e.g., "6.17-rc1") to avoid the need for frequent comment updates that would create unnecessary maintenance overhead.

Learning: The Armbian build system references Linux kernel versions in the form "tag:v6.14.4" in the KERNELBRANCH variable, even when point release tags might not be directly visible in the upstream repository in the same form.

Learning: For the Armbian build project, maintaining consistency with existing patches across U-Boot versions (such as between 2025.01 and 2025.04) is prioritized over refactoring individual patches for code improvements.

Learning: For the interactive kernel selection in Armbian, KERNEL_MAJOR_MINOR and KERNEL_DESCRIPTION are parsed from family.conf but deliberately not set as environment variables to avoid potential interference with other parts of the build system.

Learning: In Armbian build system configuration files like config/sources/families/*.conf, KERNELSOURCE is explicitly declared when using unofficial or 3rd party kernel repositories (like the "dev" branch using https://github.com/apritzel/linux), but can be omitted when using the standard mainline kernel (like the "edge" branch) since it will fall back to the default mainline source.

Learning: In Armbian build system configuration files like config/sources/families/*.conf, when KERNELSOURCE is not explicitly declared in a case branch, the system falls back to a default KERNELSOURCE value, so missing KERNELSOURCE declarations are not critical issues.

Learning: In Armbian board configuration files (config/boards/*.conf, *.csc, etc.), do not use kernel_config_set, kernel_config_set_m, kernel_config_set_y, or custom_kernel_config__* functions to modify kernel configuration. Kernel configuration is associated with LINUXFAMILY/BOARDFAMILY, not individual BOARD. Board-specific kernel modifications cause inconsistency in kernel packages published to the apt repository because boards within a family share the same kernel packages. Kernel configuration changes must be made in the appropriate kernel config file (e.g., config/kernel/linux-*-*.config) or in family configuration files (config/sources/families/*.conf, *.inc) instead.

Timestamp: 2025-09-27T21:47:58.020Z
Learning: In the Armbian build system, kernel configuration files in config/kernel/ are generated through an automated process: taking previous config → applying scripted changes from armbian-kernel.sh → running kernel's `make oldconfig` → processing by Armbian machinery back into config files. This automated process properly handles kernel configuration dependencies and reduces the likelihood of manual configuration errors.

Learning: In the Armbian build system, the modern recommended approach for kernel configuration is to use the kernel-config command via "./compile.sh BOARD=boardname BRANCH=branchname kernel-config" instead of the deprecated KERNEL_CONFIGURE=yes flag. This provides a two-step workflow: configure using menuconfig, then build, with better transparency and control over configuration changes.

Timestamp: 2025-09-14T06:29:18.958Z
Learning: In the Armbian build system, vendor branch configurations in family files are designed to be shared across multiple SoCs within the same family that use the same vendor kernel tree. For example, rk35xx and rockchip-rk3588 families both use identical vendor branch settings (same KERNELSOURCE, KERNELBRANCH, and KERNELPATCHDIR), demonstrating that vendor branches are intentionally generic rather than SoC-specific.

Learning: Armbian kernel configuration files like linux-filogic-current.config are autogenerated overlays on top of arch defconfig. Comments added manually will be lost during future updates by maintainers, and explicit "CONFIG_OPTION is not set" statements aren't needed for mutually exclusive options since these are overlay configs that only specify changes from the base configuration.

23-23: No changes needed — version format is correct.

KERNEL_MAJOR_MINOR in Armbian uses the "MAJOR.MINOR" format (e.g., "6.18") without the RC suffix. RC versions are specified via KERNELBRANCH or KERNELSOURCE, not by appending "-rc" to KERNEL_MAJOR_MINOR. The change to "6.18" is correct, and the mediatek-next branch reference handles the RC designation. KERNEL_MAJOR_MINOR must remain set as it's used throughout the build system for kernel configuration and versioning.

Do we even need to set the Kernel_Major_Minor ?

This is needed for sunxi* as we have tons of patches, elsewhere most likely not.

Let’s keep it for 25.11 then and check back for 26.02

KERNEL_MAJOR_MINOR is required for all kernel related operations for all families.
