DVB USB issues we has currently
Hello,
Here we are, that's the first part I am going to fix as a GSoC project. Work is planned to start after two weeks but better to discuss beforehand.
And wish-list is now open!
I see two big DVB USB issues including multiple small issues;
1)
Current static structure is too limited as devices are more dynamics nowadays. Driver should be able to probe/read from eeprom device configuration.
Fixing all of those means rather much work - I think new version of DVB USB is needed.

2)
Suspend/resume is not supported and crashes Kernel. I have no idea what is wrong here and what is needed. But as it has been long term known problem I suspect it is not trivial.

I'm looking forward to see RFCs about proposals for additions to dvb- usb's structure. Especially the ugly device-usb-id-referencing.
What do you mean by "new version"?

Are you sure that suspend/resume-crashes are related to dvb-usb?
Maybe the refactoring of some buffer-handling should be considered.
Also adding support for hybrid (analog+dvb-devices) is missing. Mike Krufky did some work somewhere which looked promising but was never merged.
best regards,

RFC is scheduled to first working week. Before that I can list all issues I am aware and I am planning to fix. Good starting point of looking problems is AF9015 driver and some other that reads device configuration from eeprom and sets config struct values.

I think it is so much changes that are very hard to do for existing dvb-usb as all individual dvb-usb drivers must be changed. But that will became clear after all changes are clear and RFC is approved.
Earlier I have mentioned for example availability of priv/state for first callbacks.
I would like to list all all device properties, which are same for chipset, and which are only for one device model (for example remote keytable).

That was one feature what I was also thinking. But I think I don't have any such device currently - at least I have no own experience. So let's see.
Also static limit for amount of individual devices in the config struct is something I would like to fix. Now it is over 10 device models, but as we have devices more than 10 it is needed to add multiple configurations. IIRC AF9015 has 3 currently.
But I am now on weekend trip. I will list issues more detailed in next week.
