A couple of these configs have gotten out of sync with is making it difficult for the automation scripting to properly re-write these configs correctly. Mostly due to the "edge" kernel being updated to the latest v6.18 kernel, but also due to the RT config not being updated in some time. Manually update these configs and check for correctness.

WalkthroughThree Linux kernel configuration files are updated for the K3 platform, bumping the defconfig reference from version 6.12 to 6.18. Changes include removal of legacy scheduling and netfilter options, addition of modern netfilter infrastructure, expanded PCI/USB/MMC support, new DRM display drivers, audio/HID devices, power management enhancements, and BeaglePlay/Greybus integrations.

Learning: In config/sources/families/include/k3_common.inc, the OP-TEE build command at line 59 should be updated in a future PR to explicitly set CROSS_COMPILE64=aarch64-linux-gnu- and CROSS_COMPILE32=arm-linux-gnueabihf- instead of relying on OP-TEE's internal defaults, for better clarity and maintainability. User glneo agreed to address this in a separate PR.

Learning: When reviewing PRs in the Armbian build system, U-Boot defconfig files and patches may be added as part of the PR changes but might not be visible in the current repository clone state during review. It's important to check the actual PR file changes directly via GitHub or the PR API to get the complete picture of what files are being added or modified.

Learning: In the Armbian build repository's kernel config rewrite workflow (.github/workflows/rewrite-kernel-configs.yml), deletion of kernel config files does not need to be handled. The workflow intentionally only captures ACMR (added/copied/modified/renamed) changes and does not need to propagate deletions to the aggregator.

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: When kernel config files are generated through Armbian's automated process (previous config → armbian-kernel.sh changes → make oldconfig → Armbian machinery processing), manual config file edits are not appropriate since they would be overwritten. Deprecated option handling should be implemented in the automated tooling instead.

Learning: In the Armbian build repository's kernel config rewrite workflow (.github/workflows/rewrite-kernel-configs.yml), the workflow is designed to rewrite existing kernel configs only. New/untracked files can be safely ignored, so using `git diff --quiet` (which ignores untracked files) is the correct approach for detecting changes rather than `git status --porcelain`.

Timestamp: 2025-11-20T18:20:11.985Z
Learning: The rewrite-patches tool (REWRITE_PATCHES=yes) in the Armbian build system can inadvertently introduce semantic changes when the u-boot/kernel git base revision differs from expected state. The tool applies patches, commits them, and re-exports them using git format-patch, which can cause the re-exported patch to reflect the base revision's state rather than preserving the original patch intent. This is particularly problematic for device tree changes like interrupt specifications. The tool currently lacks validation mechanisms to detect such semantic drift, and affected patches must be manually corrected after rewriting.

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.

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.

Learning: In Linux kernel 6.13 and later, CONFIG_ZBUD was deprecated and is scheduled for removal in kernel 6.15. The zbud compressed page allocator was found to consume more memory than alternatives like zsmalloc. Therefore, CONFIG_ZSWAP_ZPOOL_DEFAULT_ZBUD becomes obsolete in current kernels, and make defconfig will auto-correct by removing such deprecated options. This demonstrates how kernel defconfigs can be backwards compatible but not forward compatible.

Learning: In the Armbian build system, kernel configurations prioritize broad hardware compatibility over optimization concerns. Even when including numerous legacy/obsolete drivers causes technical issues like increased initramfs size and slower enumeration, the project philosophy is to "appease the masses" by ensuring maximum device compatibility rather than optimizing for specific use cases.

Learning: In Linux kernel configuration, some `=y` (builtin) options are infrastructure or feature flags that enable subsystems or features for modular drivers, rather than directly compiling code into the kernel. For example, in Armbian wireless configs, options like CONFIG_SPARD_WLAN_SUPPORT=y, CONFIG_SC23XX=y, CONFIG_WCN_BSP_DRIVER_BUILDIN=y, CONFIG_UNISOC_WIFI_PS=y are module infrastructure/feature enablers, while the actual drivers (CONFIG_WLAN_UWE5621=m, CONFIG_WLAN_UWE5622=m) remain as loadable modules. These infrastructure options don't cause kernel bloat.

Learning: In the Armbian build system's kernel configuration, when CONFIG_EXT2_FS=y and CONFIG_EXT3_FS=y are both set to built-in, EXT4 filesystem support becomes automatically available/hard-coded without requiring an explicit CONFIG_EXT4_FS line in the configuration file. This is specific to how Armbian handles kernel configuration and differs from typical standalone Linux kernel configuration behavior.

Learning: In Armbian's Rockchip vendor kernel branches (rk35xx-vendor), device tree files may not require the same headers as mainline Linux. For example, input key definitions like KEY_BACK and KEY_VOLUMEUP may be handled differently in BSP kernels and don't necessarily need explicit includes like <dt-bindings/input/input.h> that would be required in mainline kernel device trees.

Learning: I2C_DESIGNWARE_SLAVE is a bool configuration option in Linux kernel Kconfig, not tristate. This means it can only be set to 'y' (enabled) or 'n' (disabled), never 'm' (module). When enabled, the slave functionality is compiled into the I2C_DESIGNWARE_CORE driver, regardless of whether the core driver is built-in or as a module.

Learning: In Linux kernel configuration, when CONFIG_CPU_FREQ_DEFAULT_GOV_ONDEMAND=y is set, the ondemand governor is implicitly enabled by default, making the explicit CONFIG_CPU_FREQ_GOV_ONDEMAND=y line redundant. The make menuconfig tool automatically removes such redundant lines. This behavior applies to CPU frequency governor configurations in general - setting a default governor automatically enables that governor.

Learning: In Linux kernel configuration for the Armbian build system, when CONFIG_EXT2_FS and CONFIG_EXT3_FS are both set to =y (built-in), CONFIG_EXT4_FS is automatically enabled/hard-coded and does not need to be explicitly specified in the configuration file. This dependency relationship means that EXT4 support is implicitly included when EXT2 and EXT3 are built into the kernel.

Learning: In Armbian's kernel configuration, both kernel_config_set_string CONFIG_LOCALVERSION '""' and kernel_config_set_string CONFIG_LOCALVERSION "" produce identical results in the final .config file (CONFIG_LOCALVERSION=""). The scripts/config tool handles quoting appropriately regardless of input format.

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: In Armbian's wireless driver configuration, CONFIG_RK_WIFI_DEVICE_* options are Rockchip-specific device registration settings, while CONFIG_WLAN_UWE* are the actual cross-platform driver modules for UWE5622 wireless chips. The UWE5622 chip (manufactured by Unisoc/Spreadtrum) is used on multiple Allwinner boards including Orange Pi Zero 2/2W/3 and Orange Pi 3 LTS, so CONFIG_WLAN_UWE5621/5622 along with Unisoc infrastructure options (CONFIG_SPARD_WLAN_SUPPORT, CONFIG_SC23XX, CONFIG_UNISOC_WIFI_PS, CONFIG_WCN_BSP_DRIVER_BUILDIN) are correct in sunxi64 kernel configs.

Learning: The chainsx/linux-filogic kernel (legacy branch) for BPI-R4 uses out-of-tree proprietary drivers (CONFIG_NET_DSA_AN8855, CONFIG_AIROHA_EN8801SC_PHY, CONFIG_AIR_AN8855_PHY, CONFIG_MDIO_AN8855, CONFIG_MFD_AIROHA_AN8855). The frank-w/BPI-Router-Linux kernel (current and edge branches) uses mainline kernel drivers instead: CONFIG_NET_DSA_MT7530 for the DSA switch and CONFIG_MEDIATEK_2P5GE_PHY for PHY support. These provide equivalent functionality for BPI-R4 networking.

Learning: In the Armbian build system, staging 802.11 drivers like CONFIG_RTLLIB, CONFIG_RTL8192E, CONFIG_R8712U are kept enabled alongside upstream rtw88 drivers because rtw88 is still under development and suffers from reliability issues. The staging drivers serve as necessary fallbacks when upstream drivers are unstable, prioritizing working hardware over avoiding technical conflicts.

Timestamp: 2025-11-10T22:05:40.490Z
Learning: In the Armbian build system, kernel branches using non-mainline/vendor forks (like BeagleBoard's linux repository) should be named "vendor" or "vendor-rt" rather than "current" or "edge". The "current" and "edge" naming is reserved for mainline kernel branches. This affects both the case statement in family config files (e.g., `vendor | vendor-rt)` instead of `current | current-rt)`) and the corresponding KERNEL_TARGET declarations in board config files.

A couple of these configs have gotten out of sync with is making it difficult for the automation scripting to properly re-write these configs correctly. Mostly due to the "edge" kernel being updated to the latest v6.18 kernel, but also due to the RT config not being updated in some time. Manually update these configs and check for correctness.
How Has This Been Tested?
