I've been doing some kernel upgrades on my backend machines, and I'm 
having problems getting some of my video devices to appear with new 
locally-built kernels. In particular:
1) My master backend includes a Hauppauge WinTV-PVR 500, but I
    can't seem to find an IVTV driver option for the 3.7.9 kernel I'm
    trying to compile. The source files seem to be present in the
    source tree, but I can't seem to find an option to make them
    compile, and when I boot into the new kernel, the /dev/video*
    files for the WinTV-PVR 500 are missing.
2) My slave backend has a pcHDTV HD-3000, but I can't seem to find
    a way to compile the CX88 drivers that it requires. As with the
    WinTV-PVR 500 on my frontend, the /dev/dvb/* device files don't
    appear when I boot into a 3.7.9 kernel. I see various CX88
    files in the kernel source tree; I just can't find a way to
    activate them for compilation.
Both of these devices work fine with my old kernels (3.3.2 on the 
frontend, 3.5.7 on the backend); I just can't figure out what's required 
to get them to actually compile, and they've been deselected when I 
copied my old .config file and did "make oldconfig". There have been a 
lot of changes in the setup for video capture devices recently, so I'm 
guessing I'm missing something. I've Googled on this, but I've not 
turned up anything useful -- just old instructions and links to kernel 
source files.
Can anybody provide me with pointers for how to get these drivers to 
compile with 3.7.x kernels? Thanks.


For the PVR-500 on 3.7.x, check for CONFIG_MEDIA_RC_SUPPORT ("remote
controller support") and CONFIG_INPUT ("generic input layer").   I haven't
had to deal with this myself, but my kernel expert told me that a
configuration dependency on these was introduced and both were required to
enable the IVTV config section that you're seeking.
