x86: onie-installer: wire up sysupgrade via ONIE install mode

2026-05-23T15:23:54Z

This adds support for sysupgrade on ONIE-installed systems. The install is chained through ONIE (using the ONIE installer image), rather than attempting to manually upgrade the partition. The idea is to allow future OpenWRT installs flexibility to use a different partition table. By putting the installer in charge of setting up the file system partition, the upgrade process needs to have no knowledge of the internals of the image. Config preservation is accomplished by appending the sysupgrade .tar.gz to the ONIE installer image. Of course this also works for a clean install using a sysupgrade.tar.gz created via `sysupgrade -b`.

x86: add onie-installer image type

2026-05-23T15:23:53Z

The current documentation for using OpenWRT on Mellanox Spectrum switches (https://openwrt.org/toh/mellanox/spectrum) suggests reflashing the entire harddrive from the recovery USB. This is not the most friendly way to install a new OS on these switches. From factory, they come with ONIE (Open Network Install Environment), which is a linux-based preboot environment for fetching an OS image from the network and installing it on disk. The installer is a self-executing bash script that executes inside the ONIE environment. The installer is expected to preserve the ONIE partition for use as recovery environement. To be a better citizen on these platforms, it would be preferrable to provide OpenWRT as an ONIE-compatible installer. This PR adds an ONIE_INSTALLER_IMAGES build option that produces an ONIE compatible .bin. The generated .bin follows the ONIE demo installer pattern [1]: it creates a new GPT partition labelled OPENWRT-ROOT on the ONIE install device, formats ext4, extracts the OpenWrt rootfs and kernel into it, installs GRUB into the existing UEFI ESP under bootloader-id "OpenWrt", and adds a NVRAM boot entry via efibootmgr. ONIE-BOOT is preserved so ONIE rescue remains available. Tested with the config at [2] on a Mellanox Spectrum SN3800 to produce a booting OpenWRT install.

x86: make CONFIG_NR_CPUS a tunable (2-512)

2026-03-28T10:51:11Z

Add KERNEL_NR_CPUS option in Global build settings → Kernel build options, allowing users to set maximum CPU count (2-512) for the image. Defaults: - x86_64: 512 CPUs (backward compatible) - x86: 8 CPUs (fix broken single-CPU default) Per-CPU data structures consume ~100-200KB each. On a 4-core system configured to NR_CPUS=4, this frees approx 76 MB of RAM: (512 - 4) × 150 KB = ~76 MB Note: CONFIG_NR_CPUS_RANGE_{BEGIN,END}= and CONFIG_NR_CPUS_DEFAULT= are set by the build system and will default to 2/512/64 per arch/x86/Kconfig These are harmless metadata and don't affect memory allocation.

config: add build config option to sign each .apk package

2026-03-02T10:08:10Z

Add a build config option to sign each individual .apk package. If individual .apk files are signed with the build key, they can be installed with 'apk add' without '--allow-untrusted' to a firmware compiled by the same buildhost. Enable the option by default, but disable it for BUILDBOT. (At the moment, since commit 084697e, only the package index is signed, which forces users to use '--allow-untrusted' when installing self-built .apk files.) Signed-off-by: Hannu Nyman
