> cxm0: unknown tuner code 0x30

Enclosed is a current snapshot of my source tree which supports
the LG Innotek tuners.

> he falls out to the "db>"-prompt.

This happens when cxm_attach fails or cxm_detach is called due
to a problem with iicbb.  The patch to iicbb.c which implements
iicbb_child_detached fixes the problem.  It sounds like somehow
you're using a module which is missing that fix.  If that's not
the case then you'll have to debug it further.

------------------8<------------------------8<------------------------

[ This is the Mar 20, 2004 snapshot of my source tree.  Included are
  changes to support some more ioctls and various PAL tuners. ]

To use the Hauppauge PVR-250 / 350 on FreeBSD 4.9 / 5.2:

  1) Use patch to apply Patch.iicbb so cxm can use the i2c bus and
     avoid a crash when unloading.

  2) Unshar the enclosed archive into /sys.

  3) Place a current version of hcwpvrp2.sys from the
     Hauppauge drivers into /sys/dev/cxm.  Extract the
     the firmware by:

       # cd /sys/dev/cxm
       # cc -o cxm_extract_fw cxm_extract_fw.c
       # ./cxm_extract_fw hcwpvrp2.sys

  4) Rebuilt your kernel with:

       device          iicbus
       device          iicbb

     as part of the configuration.

  5) Install the new kernel and reboot.

  6) Make and install the cxm driver by:

       # cd /sys/modules/cxm
       # make
       # cp cxm/cxm.ko cxm_iic/cxm_iic.ko /modules
       # kldload cxm_iic
       # kldload cxm

     At which point your console should say something like:

       cxm0: <Conexant iTVC15 MPEG Coder> mem 0xd8000000-0xdbffffff irq 12
         at device 10 .0 on pci0
       cxm_iic0: <Conexant iTVC15 / iTVC16 I2C controller> on cxm0
       iicbb0: <I2C bit-banging driver> on cxm_iic0
       cxm0: Philips FI1236 MK2 tuner
       cxm0: SAA7115 rev 1 video decoder
       cxm0: MSP3435G-B6 audio decoder
       cxm0: IR Remote
       cxm0: encoder firmware version 0x2040011
       cxm0: decoder firmware version 0x2020023

  7) On FreeBSD 4.9 make the device nodes by:

       # cd /dev
       # ./MAKEDEV bktr0

     On FreeBSD 5.2 the device node is /dev/cxm0 and
     magically appears when the cxm modules is loaded.

A subset of the bt848 and meteor ioctls are supported.
The more interesting ones being:

  TVTUNER_SETCHNL - Set the channel (default to 4).

  BT848_SCAPAREA -  Set the capture area / format (defaults to DVD).

                    VCD: 352 x 240 or 352 x 288
                    SVCD: 480 x 480 or 480 x 576
                    DVD: 720 x 480 or 720 x 576

  METEORCAPTUR -    Start / stop the capture.

                    Capture is also started if a read
                    occurs when the data buffer is empty.

To capture a MPEG program stream from the current channel
simply cat /dev/bktr0 > filename.mpeg.  Though to ensure
a clean capture you probably want to do something like:

  1) Read data until the TV show has ended.

  2) Use METEORCAPTUR to end the capture.

  3) Use poll to determine if there is any data
     remaining in the device.  Read the data as
     long as poll says there's data in the buffer.

otherwise the end of the mpeg program stream will probably be
corrupt.
