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 Haup- pauge PVR-250/350. It uses the bktr(4) and Meteor driver ioctls. Note that in order for the cxm(4) driver to work properly, the necessary firmware files have to be extracted from the driver CD-ROM prior to com- piling 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: * Hauppauge PVR-250 * Hauppauge PVR-350 The following tuners are known to work: * Philips FI1216 MK2 * Philips FI1236 MK2 * Philips FI1246 MK2 * Philips FM1216 * Philips FM1216ME MK3 * Philips FM1236 * Philips FM1246 * Philips FQ1216ME * Philips FQ1216ME MK3 * Temic 4006 FH5 * Temic 4009 FR5 * Temic 4036 FY5 * Temic 4039 FR5 * Temic 4066 FY5 * LG Innotek TPI8PSB11D * LG Innotek TPI8PSB01N * LG Innotek TAPC-H701F * LG Innotek TAPC-H001F * LG Innotek TAPE-H001F * Microtune 4049 FM5 * TCL 2002N-6A * 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.
