I just checked v4l and it only build for kernels >= 2.6.12. Or do we
want to have that as a minimal kernel for ivtv, too?
Where did you see this? If you are referring to the rule inside
Make.config, that instructs the compiler to only build DVB support for
2.6.12 and up. This should not affect ivtv.
We try to always keep v4l-kernel cvs backwards compatable.
How far back?
We *should* support all vanilla 2.6.X kernels, and also 2.4.X kernels,
but I do not know how far back 2.4.X is supported, as I haven't yet
tried it myself.
If you find that v4l-kernel is not backwards compatable with your
vanilla kernel, please let us know on the v4l mailing list,
Already posted there.
or better yet, send us a patch.
It might be helpful for me to point out the following:
We are compatible with Vanilla 2.6.X kernels, through the use of #IF
KERNEL_VERSION and compat.h magic.... HOWEVER, some non-standard kernels
have backported newer features into older kernels, and our tests based
on KERNEL_VERSION fail in these cases. Because of this, sometimes
builds will fail on these non-standard kernels. If you would like to
help us to resolve these issues, what we will need is a better method of
detecting version-specific code, without testing for #IF KERNEL_VERSION
. Some of these things can be tested by using other kinds of macros...
Take a look inside v4l-kernel/v4l/compat.h to get a better idea of what
I'm talking about.
