Use adapters with multiple frontends

[silid]

Some dual tuner cards may have multiple devices on the same adapter, eg. adapter0 may have demux0, demux1, dvr0, dvr1, frontend0 and frontend1

Currently tvheadend only allows access to device 0 on each adapter, rather than noticing that there is actually more than one device on the adapter.

until it is solved you can create directory in /dev/adapter1/ and then symlinks to /dev/adapter0/frontend1 /dev/asapter1/frontend0

Adds support for adapters with multiple frontends

[silid]

This patch adds support for adapters with multiple frontends.

It doesn't address the display in the ui:

Hardware
Device path:
/dev/dvb/adapter0
Device name:
STV090x Multistandard

I would like it to display the path to the frontend rather than the adapter but I couldn't see where that data came from.

This is a related issue that should probably be fixed during progress on handling multiple adapters.

At the moment, you'll end up with two identical "Adapter name" strings identifying the decices within Tvheadend. This will also happen with using two of the same kind of adapter, and dual headed adapters that report as two logical adapters.

The "Adapter name" strings generated should be unique, to avoid problems when configuring.

But is it possible to record from both frontends at the same time?

I believe there adapters which support multiple frontends (DVB-T and DVB-S) but only one can
be active at a single time?

My dual tuner cards  Mystique Satix S2 Dual show as one adapter with two different frontends but both can be accessed and addressed simultaneously as though they were separate cards.

My patch above allows me to use them that way. It doesn't address the issue by barberio about the device naming. But for me that was minor as I could use my cards to their potential. I'd rename the cards in the DB so I knew which were which.

(ps. please don't wait until 3.0 to apply my patch :) )
