This is really a FAQ in this list, and if I weren't too busy, I would now take the chance and hack up a wiki page on this. Please browse the mailing list archives for the shared irq topic. And if you (anyone else is invited as well) would like to do us a favour, put what you find into a new wiki FAQ page on xenomai.org so that we can simply cite it on future postings like this. :) Jan PS: If you stumble over the RT-IRQ-stub-for-Linux-devices approach in the archive: I have some idea to ease the development, but it is stalled due the limited time to work it out. If you feel like you need such a stub, I can tell you more, just ask again. --------------enigC79C90F5FC7FEE711BEFF69B Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.5 (GNU/Linux) Comment: Using GnuPG with SUSE - http://enigmail.mozdev.org iD8DBQFG/8WOniDOoMHTA+kRAkN7AKCE41g0Pek/1DhvhD2+FQYliCMY7wCdF2qC xa1zfF2oz+QSTeLvirL4Kfo= =T0zs -----END PGP SIGNATURE----- --------------enigC79C90F5FC7FEE711BEFF69B--
