Note: while building ALSA modules did fail in some versions for

Blindly disabling ALSA for all Ubuntu users would be a huge regression
for users.

I agree with this premise for firedtv, but see my comment above about ALSA.

Yeah, blindly disabling it, if some versions work is not the right thing to do.
I'm not an Ubuntu user, so, I'm not sure when it was fixed. Still, from time to time,
people complain to me about this problem with some Ubuntu versions. The last complains I
heard were with some netbook versions of Ubuntu-based distros.
If there's a way to check what versions have broken alsa headers, then the checker should
just disable to the broken ones. Otherwise, the better way seems to just print a warning
message that ALSA might not be working, but keep it enabled.
Cheers,
Mauro

Really, the only thing I would do is disable the ones that break
compilation. this is ONLY firedtv.
I doubt if anyone would read the messages during compilation.
I'll have a look at the logic.

On
Linux 2.6.28-19-generic
the problem is tackled already:
DVB_FIREDTV_IEEE1394: Requires at least kernel 2.6.30
On newer linux versions (I have tried Linux 2.6.32-24-generic) the
problem is NOT that the modules dma is not present, it is just that the
required header files are not present in
/usr/include
Another location mighte have been:
ls -l /usr/src/linux-headers-2.6.28-19-generic/include/config/ieee1394
but that only contains:
-rw-r--r-- 1 root root 0 2010-09-16 18:25 dv1394.h
drwxr-xr-x 3 root root 4096 2010-06-15 20:12 eth1394
-rw-r--r-- 1 root root 0 2010-09-16 18:25 eth1394.h
-rw-r--r-- 1 root root 0 2010-09-16 18:25 ohci1394.h

-rw-r--r-- 1 root root 0 2010-09-16 18:25 video1394.h
Can you indicate where following files should be located ?
dma.h
csr1212.h
highlevel.h
In that case checking if the dma.h file is present might be the best way
forward.
I'll also file an ubuntu bug once I know what is missing where.
I could not find an entry in launchpad on this issue yet.

All of them are at the same place:

This is probably the best thing. A check for dma.h may also work. If you want,
do a patch for it and submit to Douglas.

I have updated launchpad bug
https://bugs.launchpad.net/ubuntu/+source/linux-kernel-headers/+bug/134222
I also created an updated make_kconfig.pl
http://linuxtv.org/hg/~jhoogenraad/rtl2831-r2/file/cb34ee1c29fc/v4l/scripts/make_kconfig.pl
Unfortunately, I forgot to commit changes to the main archive the first
time. I do not know how to make a patch file for this one file, without
have all other changes in the two commits as well.
I cannot find a hg export command to make a patch for this one file
between versions spanning two commits.
Douglas: can you help ?

You can just do a diff with upstream. Anyway, I'm enclosing the merged patch.
There's one problem on it:
$dmahplace="/usr/src/linux-headers-$dmahplace/include/config/ieee1394/dma.h";
Don't use absolute names here. -hg build system is smart enough to get the directory
where the kernel is installed, depending on what version you're compiling against
(you may change it with "make release").
Based on sub kernelcheck(), were we have:
my $fullkernel="$kernsrc/fs/fcntl.c";
I suspect that using:
$dmahplace="$kernelsrc/include/config/ieee1394/dma.h";
should work properly.

Mauro:
On my system, the call to make_kconfig reads:
./scripts/make_kconfig.pl /lib/modules/2.6.28-19-generic/build
/lib/modules/2.6.28-19-generic/build 1
Using $kernelsrc yields the following error:
Global symbol "$kernelsrc" requires explicit package name at
./scripts/make_kconfig.pl line 694.
Using
$dmahplace="$kernsrc/include/config/ieee1394/dma.h";
yields the following INCORRECT expansion:
/lib/modules/2.6.28-19-generic/build/include/config/ieee1394/dma.h
this is the place where I am building into, which is different from the
place where Ubuntu places the include files from the package
Thus I built an expression to get:
/usr/src/linux-headers-2.6.28-19-generic/include/config/ieee1394/dma.h
as I described in the mail of yesterday.
Now, I realize that the header files could ALSO be present in the build
directory, so there should be a check on that as well, as otherwise the
FIREDTV is incorrectly disabled on other distros, or source builds.
Yes, and I know all of this is ugly ....

Huh? Are you sure that Ubuntu doesn't have a symbolic link at /lib/modules/2.6.28-19-generic/build pointing
to /usr/src/linux-headers-2.6.28-19-generic/?
If it doesn't have, then all compat checks done by make_config_compat.pl would fail.

It is not just ugly. It will break compilation on Ubuntu with:
$ make release DIR=<some dir>

Douglas:
I have an updated make_kconfig.pl for Ububtu on:
http://linuxtv.org/hg/~jhoogenraad/rtl2831-r2/file/cb34ee1c29fc/v4l/scripts/make_kconfig.pl
Could you test if make allyesconfig actually keeps FIREDTV enabled on a
non-Ubuntu system ?
If so, can you merge this version into the main stream ?
Mauro:
You are very right. I did not look far enough.
The expanded place where I expect the dma.h file would be (as I
/lib/modules/2.6.28-19-generic/build/include/config/ieee1394/dma.h
note that the letters "el" should be removed from your first expression
$dmahplace="$kernelsrc/include/config/ieee1394/dma.h";
needs to be:
$dmahplace="$kernsrc/include/config/ieee1394/dma.h";
Thanks a lot for helping !

Ok, now it looks correct on my eyes, and it should not hurt compilation
with make release and with distros that do a good job with their kernel
packages.
I'll let Douglas review and test, as he is the maintainer.
It would be better if you could send him a diff. you may use hg diff to generate
it against an older version, in order to merge all your make_kconfig.pl patches,
or just create a new clone from master and apply it there.
A side question: when do you intend to send us the patches for the Realtek
rtl2831?
Cheers,
Mauro.

Basically, I'm waiting for somebody to take up the task to include IR
support in Antti's branches. I don't have the knowledge to do so.
In the mean time, I just maintain the code from Realtek on a sync with
mainline only base in hg, as the code is really sub-standard.
http://www.linuxtv.org/wiki/index.php/Realtek_RTL2831U
I have seen that Realtek keeps updating their Windows code, and the v4l
port, at least for the RTL2832.
I see the "recipes" to use that on many forums.
