Hi,
I am observing an UEvent issue in cpufreq.c. The cpufreq_add_dev() function is called whenever a core is 'onlined'. we expect the kobject_uevent() method in cpufreq_add_dev() to send an UEvent with KOBJ_ADD as the action parameter.
But this call fails because of the 'filter function' inside kobject_uevent_env inside lib/kobject_uevent.c. The ->filter points to 'dev_uevent_filter' in drivers/base/core.c, where the check for 'device_ktype' fails.
Error message: kobject: 'cpufreq' (e5bbf290): kobject_uevent_env: filter function caused the event to drop!
As far as I can see, we need a kset, and associated filter function inside cpufreq.c to get this working. Is this the right way to go ? Any other easy/correct ways to get it working ? Please advise.
Thanks, Durga
