9) Highly reconfigurable hardware - Julien Beraud

- 44 sub-devices connected with an interconnect.
- As long as formats match, any sub-device could be connected to any

- The result is 44 * 44 links at worst.
- A switch sub-device proposed as the solution to model the
- interconnect. The sub-devices are connected to the switch
- sub-devices through the hardware links that connect to the
- interconnect.
- The switch would be controlled through new IOCTLs S_ROUTING and
- G_ROUTING.
- Patches available:

but the patches are from 2005. So I guess I'll need some guidance here...

Yeah, that's where it began (2015?), but right now I can only suggest to
wait until there's more. My estimate is within next couple of weeks /
months. But it won't be years.

Ok, week or two would be ok, couple of months is not. And all I need
is single hook in common structure.

So if g_endpoint_config hook looks sane to _you_, I suggest we simply
proceed. Now, maybe Mauro Carvalho Chehab [off-list ref]
or Laurent or Julien will want a different solution, but
then... they'll have to suggest something doable now, not in couple of
months.

Does that sound like a plan?

Mauro added to cc list, so we can get some input.

side note: It's an kernel-internal API only used by the media
subsystem. Code can be easily updated to use an improved API
at any time.
