systemd-udevd provides support for significantly more hardware than mdevd does. Therefore, switch to it. Signed-off-by: Demi Marie Obenour <demiobenour@gmail.com> --- Changes in v4: - Use 'udevadm trigger --action=add' at coldplug time. - Ensure that the wrapper does not exit after the first message. - Include the hardware database. - sd-notify-adapter should not exit if it receives a message without READY=1. - Link to v3: https://spectrum-os.org/lists/archives/spectrum-devel/20250928-udev-v3-0-bb0... Changes in v3: - Try to avoid net-add running twice. - Use full systemd instead of systemdMinimal, as something else already pulls it into the image. - Hopefully fix integration tests. - Link to v2: https://spectrum-os.org/lists/archives/spectrum-devel/20250924-udev-v2-2-608... Changes in v2: - Use more optional arguments instead of positional parameters in sd-notify-wrapper. - Explain why explicit modprobe is needed. - Link to v1: https://spectrum-os.org/lists/archives/spectrum-devel/20250913-udev-v1-0-ead... --- Demi Marie Obenour (2): tools: Add adapter tool for services using sd_notify host/rootfs: Switch to systemd-udevd LICENSES/LGPL-2.1-or-later.txt | 502 +++++++++++++++++++++ host/rootfs/Makefile | 2 +- host/rootfs/default.nix | 118 ++--- host/rootfs/file-list.mk | 33 +- host/rootfs/image/etc/mdev.conf | 7 - host/rootfs/image/etc/mdev/listen | 11 - host/rootfs/image/etc/mdev/wait | 14 - host/rootfs/image/etc/s6-rc/card0/type.license | 2 - host/rootfs/image/etc/s6-rc/card0/up | 4 - host/rootfs/image/etc/s6-rc/kvm/timeout-up | 1 - host/rootfs/image/etc/s6-rc/kvm/timeout-up.license | 2 - host/rootfs/image/etc/s6-rc/kvm/type | 1 - host/rootfs/image/etc/s6-rc/kvm/type.license | 2 - host/rootfs/image/etc/s6-rc/kvm/up | 4 - host/rootfs/image/etc/s6-rc/mdevd-coldplug/type | 1 - host/rootfs/image/etc/s6-rc/mdevd-coldplug/up | 4 - .../image/etc/s6-rc/mdevd/notification-fd.license | 2 - host/rootfs/image/etc/s6-rc/mdevd/run | 5 - .../contents.d/systemd-udevd-coldplug} | 0 .../dependencies.d/systemd-udevd} | 0 .../s6-rc/{card0 => systemd-udevd-coldplug}/type | 0 .../type.license | 0 .../image/etc/s6-rc/systemd-udevd-coldplug/up | 6 + .../s6-rc/{mdevd => systemd-udevd}/notification-fd | 0 .../s6-rc/systemd-udevd/notification-fd.license | 2 + host/rootfs/image/etc/s6-rc/systemd-udevd/run | 15 + .../image/etc/s6-rc/{mdevd => systemd-udevd}/type | 0 .../s6-rc/{mdevd => systemd-udevd}/type.license | 0 .../contents.d/systemd-udevd-coldplug} | 0 .../contents.d/systemd-udevd-coldplug} | 0 .../weston/dependencies.d/systemd-udevd-coldplug | 0 host/rootfs/image/etc/s6-rc/weston/run | 7 +- .../image/etc/udev/rules.d/99-spectrum.rules | 15 + host/rootfs/image/usr/bin/run-vmm | 1 + host/rootfs/image/usr/bin/systemd-udevd | 1 + .../{etc/mdev/net/add => usr/libexec/net-add} | 0 tools/default.nix | 1 + tools/meson.build | 1 + tools/sd-notify-adapter/meson.build | 4 + tools/sd-notify-adapter/sd-notify-adapter.c | 114 +++++ 40 files changed, 724 insertions(+), 158 deletions(-) --- base-commit: c5d5786d3dc938af0b279c542d1e43bce381b4b9 change-id: 20250911-udev-24cf4bf68fbe -- Sincerely, Demi Marie Obenour (she/her/hers)
