Hi,
I've recently bought two cards HVR-2200 rev 0700:8940 and installed them
into one PC. Kernel module saa7164 was launched by linux (under Ubuntu
11.04, with kernel 2.6.38-10-generic-pae), but it didn't recognize my
cards (so, it selected card 0 : unknown).
I've seen a new patch on your mailing list (see archive [1] and the
patch [2]), but it was apparently only applied on kernellabs.org and not
in the linuxtv.org archive.
So I've downloaded the Ubuntu linux source (with apt-get install
linux-source), I've patched it following the diff [2] and I've compiled
this new kernel.
Now when I reboot it, it works really well : I don't need any more to
say which cards I've in /etc/modprobe.d/saa-7164.conf and both were well
recognized (I've seen my four adapters in /dev/dvb/adapter[0,1,2,3]).
So, could you apply this patch also on your source please (and try it to
confirm my tests)?
Thank you very much,
Adrien Dorsaz

I've just done something similar.
I installed the source code for my Ubuntu 10.10 x86 32bit kernel:
apt-get source linux-image-2.6.35-30-generic-pae
I got the source code of the version of the saa7164 driver that supports
the "0700:8940" revision of the 2200 card from Kernel Labs by:
git clone git://kernellabs.com/stoth/saa7164-stable.git
cd saa7164-stable
git checkout 87e0c0378bf2068df5d0c43acd66aea9ba71bd89
make clean
Many thanks to Steven Toth (driver author) for telling me about the
"87e0c0378bf2068df5d0c43acd66aea9ba71bd89" commit.
I then replaced the Ubuntu kernal source's
"linux-2.6.35/drivers/media/video/saa7164/" directory with that from the
above "87e0c0378bf2068df5d0c43acd66aea9ba71bd89" commit and then
recompiled the ubuntu kernel source.
I found the instructions at
"http://linuxtweaking.blogspot.com/2010/05/how-to-compile-kernel-on-ubuntu-1004.html<http://linuxtweaking.blogspot.com/2010/05/how-to-compile-kernel-on-ubuntu-1004.html>"
for getting the ubuntu kernel source code and recompiling it most helpfull.
I got the following firmware from http://www.steventoth.net/linux/hvr22xx :
dvb-fe-tda10048-1.0.fw
NXP7164-2010-03-10.1.fw
After putting the firmware files into place and doing a cold reboot, the
card's DVB-T functionality seems to be working fine within my Mythtv 0.24.
Regards,
Declan
