If you think it is not working fine, then lets have Kay fix it. Also with the integration of devtmpfs all the last issues with initial device nodes are solved and udev execution time on a really static environment is almost non existent. If you have a problem with your boot time, then it is somewhere else. I highly doubt it is really a problem of udev.

Can we just add some code in phonesim to make it look like a pseudo serial device which can be managed by udev? That is, if we start the phonesim, it will simulate some tty ports under /dev and udevd will inform the oFono there is a new device (We need some rule for phonesim). And the device disappears if phonesim meets an end. Maybe this is possible if we can send message to udevd the same way as kernel via netlink. > >Regards > >Marcel > Regards, -Yang ___ ofono mailing list ofono@ofono.org http://lists.ofono.org/listinfo/ofono

Every serial port is present in udev, so you can write proper udev rules for it. A modem with a serial port for GSM and another one CDMA will be just presented as two modems inside oFono. So no problem at all. So modemconf plugin will be removed since it is not needed at all. The only component that needs it is the phonesim plugin. And that will get its own configuration file.

RE: Removal of modemconf plugin
Hi Marcel, What about dual mode modems that with two different serial ports? e.g. a modem support both GSM and CDMA, there is a serial port For GSM, and there is a serial another for CDMA. Why not keep both udev and modemconf plug-in. It remains for the user To decide which way to use. I think maybe we can change the compile Scrips, let user to select which plug-in to use.

I'll try to test it against meego kernel, but I have some problems (like, usb ethernet does not get up so I could see what is happening there.) However, I can post the almost completely untested version once I've split it into digestable pieces. -- Pekka.Pessi mail at nokia.com ___ ofono mailing list ofono@ofono.org http://lists.ofono.org/listinfo/ofono
