[RFC PATCH 0/1] [media] pci: Add support for DVB PCIe cards from Prospero Technologies Ltd.

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The Vortex PCIe card by Prospero Technologies Ltd is a modular DVB card
with a hardware demux, the card can support up to 8 modules which are
fixed to the board at assembly time. Currently we only offer one 
configuration, 8 x Dibcom 7090p DVB-t tuners, but we will soon be releasing
other configurations. There is also a connector for an infra-red receiver 
dongle on the board which supports RAW IR.

The driver has been in testing on our systems (ARM Cortex-A9, Marvell Sheva, 
x86, x86-64) for longer than 6 months, so I'm confident that it works. 
However as this is the first Linux driver I've written, I'm sure there are 
some things that I've got wrong. One thing in particular which has been 
raised by one of our early testers is that we currently register all of 
our frontends as being attached to one adapter. This means the device is
enumerated in /dev like this:

/dev/dvb/adapter0/frontend0
/dev/dvb/adapter0/dvr0
/dev/dvb/adapter0/demux0

/dev/dvb/adapter0/frontend1
/dev/dvb/adapter0/dvr1
/dev/dvb/adapter0/demux1

/dev/dvb/adapter0/frontend2
/dev/dvb/adapter0/dvr2
/dev/dvb/adapter0/demux2

etc.

Whilst I think this is ok according to the spec, our tester has complained 
that it's incompatible with their software which expects to find just one 
frontend per adapter. So I'm wondering if someone could confirm if what 
I've done with regards to this is correct.

I've tested this patch by applying it to current media-master and it applies 
cleanly and builds without issue for me.
