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


cxm -- Conexant iTVC MPEG Coder


To compile this driver into the kernel, place the following lines in your kernel configuration file: device iicbus device iic device iicbb device cxm


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.


The following cards are known to work: o Hauppauge PVR-250 o Hauppauge PVR-350 The following tuners are known to work: o Philips FI1216 MK2 o Philips FI1236 MK2 o Philips FI1246 MK2 o Philips FM1216 o Philips FM1216ME MK3 o Philips FM1236 o Philips FM1246 o Philips FQ1216ME o Philips FQ1216ME MK3 o Temic 4006 FH5 o Temic 4009 FR5 o Temic 4036 FY5 o Temic 4039 FR5 o Temic 4066 FY5 o LG Innotek TPI8PSB11D o LG Innotek TPI8PSB01N o LG Innotek TAPC-H701F o LG Innotek TAPC-H001F o LG Innotek TAPE-H001F o Microtune 4049 FM5 o TCL 2002N-6A o TCL M2523-5N-E

The cxm driver first appeared in the FreeBSD-multimedia@ mailing list in January 2004 and in the FreeBSD Ports collection in October 2004. It was ported to DragonFly 2.3 by Sascha Wildner.
