[edit] About

I finally got my HVR-4000 to work, after hours of failing and trying (which was from full IRQ-channels, but that's another story...). Had to use the mercurial-version of the v4l-dvb-drivers patched with diffs from http://dev.kewl.org/hauppauge. I only tried the ones with single-frontend-support (sfe-7285.diff, dated 03-Mar-2008).

[edit] Setup

The hardware and kernel I am using at the time of writing is:

  • 2.6.23-gentoo-r8 (x86)
  • Hauppauge HVR-4000 (non MCE edition with Hauppauge Remote)
  • Nvidia Geforce 6600GT
  • MSI-6590 (KT4-ultra BSR)
  • AMD Athlon XP 2800+

[edit] Obtaining Latest v4l-dvb Sources

If you don't have mercurial installed: 

emerge -av mercurial

Next step is to clone the latest version of the tree.

Note: The last revision I know of that works with the sfe-diff is 127f67dea087 , so for now check that one out instead
hg clone -r 127f67dea087 http://linuxtv.org/hg/v4l-dvb

Now you will have a sub directory called v4l-dvb containing the sources from revision 127f67dea087.

[edit] Creating Kernel Patch and Modules

[edit] Kernel

Not really sure about what is required, but this works for me:

Linux Kernel Configuration: Kernel 2.6 
 Device Drivers --->
      Multimedia Devices --->
            <M> Video For Linux
                   [*]   Enable Video For Linux API 1 (DEPRECATED)
                   ---   Enable Video For Linux API 1 compatible Layer
                   [*]   Video capture adapters  --->
                   [ ]   Radio Adapters  --->
            <M> DVB for Linux
                   [*]   Load and attach frontend modules as needed
                   [*]   DVB/ATSC adapters  --->
                   [*] DAB adapters
            < >   DABUSB driver

If you need to make any changes to your kernel, do so & reboot before proceeding.

[edit] v4l-dvb compilation 

wget http://dev.kewl.org/hauppauge/sfe-7285.diff
patch -p1 < sfe-7285.diff
make
make install

Remember if you modify your kernel or upgrade it, you will need make & reinstall the modules again

[edit] Testing

In order to check that the modules work: 

modprobe cx88_dvb

This should automatically pull any modules it needs, and detect your HVR-4000 correctly. 

dmesg

Check the output, the card should now have successfully been detected. See here for sample output.

Next check your /dev entries:

DVB 

ls -l /dev/dvb/adapter0
crw-rw---- 1 root video 212, 4 Nov 14 11:31 demux0
crw-rw---- 1 root video 212, 5 Nov 14 11:31 dvr0
crw-rw---- 1 root video 212, 3 Nov 14 11:31 fontend0
crw-rw---- 1 root video 212, 7 Nov 14 11:31 net0

[edit] Autoloading Modules

I added the following:

File: /etc/modules.autoload.d/kernel-2.6 
 cx88_dvb

cx88_dvb pulls in all the relevant modules for DVB and IR

[edit] Selecting frontend

File: /etc/modprobe.d/cx88 
 #Set HVR-4000 driver frontend
 #frontend=0 is dvb-s, 1 is dvb-t
 options cx88-dvb frontend=0

Then run update-modules to remake the modprobe.conf file.

[edit] LIRC

Finally, you need to compile lirc with 'devinput' support, NOT hauppauge NOR hauppauge-dvb:

File: /etc/make.conf 
LIRC_DEVICES='devinput'

Then install LIRC using: emerge lirc. Keycodes are on the external link. See LIRC for further information.
