Mode and modes are both sysfs variables so KOBJ_CHANGE should work to send the events to hal. These are the public events that everyone should know about. That leaves my private monitor change interrupt event in kobject_hotplug(&info->class_device->kobj, KOBJ_MOUNT); It doesn't make sense to remove/add the framebuffer device just because the monitor attached changed. Remove/add would force X to close the framebuffer device and lose all of the state loaded inside of it (font cache, textures if DRM is running) . What about adding a few defines for KOBJ_HELPER_1, KOBJ_HELPER_2, KOBJ_HELPER_3, etc? Wouldn't this be better than making specific defines for private helpers like my DDC decoder? KOBJ_HELPER would be context specific on the class of the device. I also want to modify request_firmware() to be more general. Secondary video cards need to be posted before the sysfs class is created. request_firmware() almost does what I need. It would be more useful if I renamed it to request_initialization() then created two events: KOBJ_FIRMWARE and KOBJ_POST. Alternatively I could pass FIRMWARE or POST as an environment variable. The user space post program is the same for all video cards. Once we get this hashed out I'll post a summary to LKML for wider comment. -- Jon Smirl jonsmirl@gmail.com ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
