Newer kernels will emit uevents with "bind" and "unbind" actions. These uevents will be issued when driver is bound to or unbound from a device. "Bind" events are helpful when device requires a firmware to operate properly, and driver is unable to create a child device before firmware is properly loaded.
For some reason systemd validates actions and drops the ones it does not know, instead of passing them on through as old udev did, so we need to explicitly teach it about them. --- BIND/UNBIND will be in 4.14. src/libsystemd/sd-device/device-internal.h | 2 ++ src/libsystemd/sd-device/device-private.c | 2 ++ 2 files changed, 4 insertions(+) diff --git a/src/libsystemd/sd-device/device-internal.h b/src/libsystemd/sd-device/device-internal.h index f4783deef..0505a2730 100644 --- a/src/libsystemd/sd-device/device-internal.h +++ b/src/libsystemd/sd-device/device-internal.h @@ -104,6 +104,8 @@ typedef enum DeviceAction { DEVICE_ACTION_MOVE, DEVICE_ACTION_ONLINE, DEVICE_ACTION_OFFLINE, + DEVICE_ACTION_BIND, + DEVICE_ACTION_UNBIND, _DEVICE_ACTION_MAX, _DEVICE_ACTION_INVALID = -1, } DeviceAction; diff --git a/src/libsystemd/sd-device/device-private.c b/src/libsystemd/sd-device/device-private.c index b4cd676c1..8839c3266 100644 --- a/src/libsystemd/sd-device/device-private.c +++ b/src/libsystemd/sd-device/device-private.c @@ -466,6 +466,8 @@ static const char* const device_action_table[_DEVICE_ACTION_MAX] = { [DEVICE_ACTION_MOVE] = "move", [DEVICE_ACTION_ONLINE] = "online", [DEVICE_ACTION_OFFLINE] = "offline", + [DEVICE_ACTION_BIND] = "bind", + [DEVICE_ACTION_UNBIND] = "unbind", }; DEFINE_STRING_TABLE_LOOKUP(device_action, DeviceAction); -- 2.14.1.581.gf28d330327-goog -- Dmitry _______________________________________________ systemd-devel mailing list systemd-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/systemd-devel
