Some comments for those who have not been following this story closely. I w= ill try to keep this S2API-relevant. The reason for considering adding multifrontend support to S2API is that S2= API will certainly add HVR4000 support, and at that point we need to consider how to handle the multiple frontends of that card. The multifrontend patch= is quite orthogonal to the S2API changes, both in the sense that it does not interfe= re with them, and in the sense that it is quite a different subject from changing the API. The updates I made bring the patch right up to date so that it can be merge= d with the head of the S2API repository. It is quite general -- it can support all= multifrontend cards (not just HVR3000/4000). It has been around for about 18 months when = Steve proposed it. Darron has been maintaining it at dev.kewl.org/hauppauge. I ha= ve used it for 9 months or so with (unmodified) Kaffeine. Darron's method for supporting DVB-S2 features is replaced by the more general S2API. In the end what the application sees is (for the HVR4000): /dev/dvb/adapter0/frontend0: DVB-S/S2 /dev/dvb/adapter0/frontend1: DVB-T Andreas' thread is the place to discuss exactly how this should work. Anywa= y = we have here a concrete implementation of one way to do it. We need to be careful not to confuse the issues to do with the API. The most important thing is to perfect and debug the design of the S2 API. But I hope multifrontend support will go in to the kernel when the HVR4000 support is = added. Perhaps we shouldn't be too scared of trying to make progress by putting it= in S2API at the most appropriate point in Steve's development schedule. Regards, Hans -- = Release early, release often.
