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

microchipsw: enable DCB by default

Switchdev driver used by microchipsw supports DCB and has not storage constraints, so enable kernel and driver DCB support by default. Signed-off-by: Robert Marko

kernel: add TIMERLAT_TRACER kernel config option

2026-01-24T21:54:29Z

This adds the TIMERLAT_TRACER kernel configuration option. The timelat tracer helps to find sources of wakeup latencies of real-time threads. Signed-off-by: Thomas Richard Link: https://github.com/openwrt/openwrt/pull/21413 Signed-off-by: Hauke Mehrtens

kernel: add OSNOISE_TRACER kernel config option

2026-01-24T21:54:29Z

This adds the OSNOISE_TRACER kernel configuration option. The osnoise tracer allows to track interference experienced by an application due to activities inside the operating system (like NMIs, IRQs ...).

This adds the HWLAT_TRACER kernel configuration option. The hwlat tracer allows to detect hardware latencies. Signed-off-by: Thomas Richard Link: https://github.com/openwrt/openwrt/pull/21413 Signed-off-by: Hauke Mehrtens

kernel: add preemption models

2026-01-24T21:52:49Z

Introduce preemption model selection with PREEMPT_NONE as the default. PREEMPT_NONE is the traditional Linux preemption model and also the best choice for servers. Signed-off-by: Thomas Richard Link: https://github.com/openwrt/openwrt/pull/21413 Signed-off-by: Hauke Mehrtens

Connect to UART via the USB-C port 2. Connect the management port 3. Boot and interrupt U-Boot 4. TFTP the OpenWrt initramfs image and boot it 5. SCP the OpenWrt eMMC GPT image to a running OpenWrt initramfs to /tmp openwrt-microchipsw-lan969x-microchip_ev23x71a-squashfs-emmc-gpt.img.gz And decompress it via: gzip -d /tmp/openwrt-microchipsw-lan969x-microchip_ev23x71a-squashfs-emmc-gpt.img.gz 6. Wipe eMMC with: dd if=/dev/zero of=/dev/mmcblk0 bs=1M 7. Flash OpenWrt eMMC image with: dd if=/tmp/openwrt-microchipsw-lan969x-microchip_ev23x71a-squashfs-emmc-gpt.img of=/dev/mmcblk0 After a restart OpenWrt will boot, and then regular sysupgrade can be used for upgrades.

config: add !USE_APK dependency to CLEAN_IPKG

2025-11-27T13:46:26Z

When USE_APK is enabled, APK replaces opkg/ipkg, leading to a build failure when CLEAN_IPKG is also selected. Add 'depends on !USE_APK' to CLEAN_IPKG to ensure this option is only selectable when opkg/ipkg is the active package manager.
