1558-1562: Validate the necessity of the TI_ADS8344 ADC driver
CONFIG_TI_ADS8344=madds an SPI ADC that is not present on most Rockchip boards.
Enabling unnecessary drivers increases kernel size and build time. Unless you have boards that actually expose this chip on the SPI bus, you can drop it to keep the defconfig minimal.-CONFIG_TI_ADS8344=m +# CONFIG_TI_ADS8344 is not set

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.

It's important to check the actual PR file changes directly via GitHub API (https://api.github.com/repos/armbian/build/pulls/{pr_number}/files) to get the complete picture of what files are being added or modified, especially for U-Boot patches that will be applied during the build process.

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.

Timestamp: 2025-06-24T10:08:40.313Z
Learning: In the Armbian build system, when a PR removes build support for a specific kernel version, version check issues for that removed version become practically irrelevant even if they appear incorrect in isolation. Context about which kernel versions are being deprecated/removed is important for understanding the impact of version-related code changes.

Timestamp: 2025-03-31T22:20:41.849Z
Learning: When porting patches between U-Boot versions (like from 2025.01 to 2025.04), rpardini prefers to maintain patches as-is rather than introducing refactoring changes, even when potential improvements are identified. This approach prioritizes consistency and reduces the risk of introducing new issues.

Timestamp: 2025-03-31T22:20:48.475Z
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.

Timestamp: 2025-04-30T16:16:47.150Z
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: 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: CONFIG_NETKIT is a valid kernel configuration option in Linux kernel 6.12 and later versions, despite not being present in earlier versions like 6.9/6.10-rc.

Timestamp: 2025-06-25T03:40:52.109Z
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: 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: CONFIG_NETKIT was introduced in Linux kernel 4.14.330 (November 2023) and enables BPF-programmable network devices that can operate in Layer 3 or Layer 2 mode. It's a valid configuration option in modern kernels including 6.12.

Timestamp: 2025-07-26T11:14:41.678Z
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 Armbian board configuration files (.csc), the standard pattern is to have only one line as a comment describing the board hardware specifications. This single-line description typically includes the SoC model, core count, RAM options, and key features like connectivity options, storage interfaces, and special features.

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 the Armbian build system, board configuration files (*.conf) follow a project standard of not including shebang lines, even though they contain bash code and are sourced by the build system. This is an established Armbian convention that individual contributors are expected to follow, and changes to this standard would require broader project maintainer approval.

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: 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 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: CONFIG_NETKIT was introduced in Linux kernel 4.14.330 (November 2023) and enables BPF-programmable network devices that can operate in Layer 3 or Layer 2 mode. It's a valid configuration option in modern kernels including 6.12.

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 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 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 the Armbian build system, when a PR removes build support for a specific kernel version, version check issues for that removed version become practically irrelevant even if they appear incorrect in isolation. Context about which kernel versions are being deprecated/removed is important for understanding the impact of version-related code changes.

Learning: When porting patches between U-Boot versions (like from 2025.01 to 2025.04), rpardini prefers to maintain patches as-is rather than introducing refactoring changes, even when potential improvements are identified. This approach prioritizes consistency and reduces the risk of introducing new issues.

Unless this file (or the hook) is updated after the final 6.16 release, users will continue to receive the -rc kernel. Please plan a follow-up bump (or remove the hard-coded RC logic) so that stable images aren’t built on a release candidate.config/kernel/linux-rockchip-edge.config (1)
1129-1132: Switching SIMPLEDRM from built-in to module may drop early framebuffer output
CONFIG_DRM_SIMPLEDRM=mmeans the generic firmware-/DT-backed framebuffer is no longer available until modules load.
On boards without an early native DRM driver (or if the rootfs is on slow media), this can leave the screen blank during boot and hide kernel panics. Verify that:
- Rockchip DRM really probes early enough on every supported board.
- SimpleDRM was not previously relied on for splash/console.
If early output is still desired, consider keeping it built-in:
-CONFIG_DRM_SIMPLEDRM=m +CONFIG_DRM_SIMPLEDRM=y
