>Description:
Installation works well, the dmesg -a|grep cxm reports:
cxm0: <Conexant iTVC16 MPEG Coder> mem 0xd8000000-0xdbffffff irq 3 at device 2.0 on pci2
cxm_iic0: <Conexant iTVC15 / iTVC16 I2C controller> on cxm0
iicbb0: <I2C bit-banging driver> on cxm_iic0
cxm0: LG Innotek TPI8PSB11D tuner
cxm0: SAA7115 rev 1 video decoder
cxm0: MSP4418G-A2 audio decoder
cxm0: IR Remote
But when you have a connexant device and other card based in bt8x8 in the same machine only work last of two. The loader sequence is:
bktr_mem
bktr
cxm
cxm_iic
>How-To-Repeat:
If dont load the bktr* modules connexant device (and tools) work fine. But when reload bktr* modules the bt8x8 chipset card dont work now.
First I created a new bktr1 with MAKEDEV and change setchannel for work with bktr1. The connexant card don't work (if dont load bktr* modules connexant card works on bktr0). setchannel reports:
open() /dev/bktr1: Device not configured
>Fix:
My solution, change the major device number for connexant devices. I read /usr/src/sys/majors and 200-248 are for user use. I modified cxm.c:
--diff--

static d_poll_t cxm_poll;
#if __FreeBSD_version < 500000
-# define CDEV_MAJOR 92
+# define CDEV_MAJOR 201
#else
# define CDEV_MAJOR MAJOR_AUTO
#endif
--end-diff--
After make and reinstall the new modules. Them remove the bktr1, tuner1 and vbi1 devices and create 3 new devices with
# mknod /dev/cxm0 c 201 0
# mknod /dev/tuner1 c 201 16
# mknod /dev/vbi1 c 201 32
The last step consist in change setchannel for cxm0. And thats all. Two devices works at the same time.
