CXM(4)                DragonFly Kernel Interfaces Manual                CXM(4)


NAME

     cxm -- Conexant iTVC MPEG Coder


SYNOPSIS

     To compile this driver into the kernel, place the following lines in your
     kernel configuration file:

           device iicbus
           device iic
           device iicbb
           device cxm


DESCRIPTION

     The cxm driver provides support for the PCI video capture on the
     Hauppauge PVR-250/350.  It uses the bktr(4) and Meteor driver ioctls.

     Note that in order for the cxm driver to work properly, the necessary
     firmware files have to be extracted from the driver CD-ROM prior to
     compiling the kernel.  The tool necessary to do this can be found in
     /usr/src/tools/multimedia/cxm/extract_fw.
