As far as i understand, the cinergyT2 driver is a bit unusual, e.g.
dvb_register_frontend is never called (hence no dtv_* log messages).
I don't know if there is others drivers like this, but this has to
be investigated cause rewritting all drivers for S2API could be a
bit of work :)
P.S.
I think there is an alternate driver for cinergyT2 actually in
developement but idon't remember where it's located neither its state.
Good to know. (I also saw your followup email). I have zero
experience with the cinergyT2 but the old api should still be working
reliably. I plan to investigate this, sounds like a bug! :)
Holger was of the opinion that having the demux in dvb-core
was stupid for devices which have no hw demux, so he
programmed around dvb-core. His plan was to add a
mmap-dma-buffers kind of API to the frontend device,
but it never got implemented.
Anyway, it's bad if one driver is different than all the others.
Hmm, I didn't realize this, good to know.
Now it's peaked my interest, I'll have to look at the code.
The existing API should still work at a bare minimum, if it's not - it
needs to.
So I looked the the cinergyT2 code, that's a complete eye-opener. It has
it's own ioctl handler, outside of dvb-core.
It's a good news / bad news thing.
The good news is that this driver will not be effected by the S2API
changes, so nothing can break.
The bad news is that this driver will not be effected by the S2API
changes, so it doesn't get the benefit.
Regardless of S2API or multiproto, I see no reason why we shouldn't
bring this driver back into dvb-core.
I don't have a device to test, but here's a patch (0% tested, with bugs
probably) that converts the module back to a regular dvb-core compatible
device, so the S2API would work with this. If anyone wants to test this,
and finds bugs - I won't get back to this driver for a couple of weeks -
so your patches would be welcome. :)
Frankly, is S2API is selected for merge and we have enough users of the
current non-dvb-core driver, I'll probably re-write it from the spec.
So much to do, so little time.
