Well, I think I implemented almost all of the v4l2 framework. Then I took t=
he=20
=46reeBSD bktr driver, separated the radio/tuner part and got it working as=
 a=20
v4l2 aware driver, too. This driver registers with the framework and=20
a /dev/v4l2/radio0 entry is being created. I got fmtools-0.99.0 up and=20
running, too.

But there is a difference to the original Linux framework. AFAIR, in Linux,=
=20
one of the kernel structures holds the open file handle, but in FreeBSD=20
there's no place for it. So I changed the internals of the framework a bit,=
=20
but the API for the applications should be the same as for Linux.

What's missing is the video part. I had not enough specs about the v4l2=20
framework to get it running. And - what was the main problem for me - I did=
=20
not have time to rewrite the bktr driver as v4l2 driver. You know, no=20
information about the v4l2 framework and no information about the bktr driv=
er=20
internals ... so I gave up.

Then, in August 2005 Julian Elischer (julian@elischer.org) asked me to give=
=20
him my work, because he wanted to do something with it. Maybe he didn't hav=
e=20
time :-(.

So before someone steps in and invents the wheel again, please contact Juli=
an=20
first :-).

Ciao,
Christian.
