When I used my system under Linux (Debian), I had connected my external dev= ice with I2C to HDMI output in my computer. After this, I have managed my exter= nal device sending/receive codes through the I2C controller. For example, I use command: i2set -y 2 0x50 0x45 0x65 For added video card I2C controller to the Linux system, I had added i2c-dev module to Linux system. I had used this command: modprobe i2c-dev After this i2c controller appears in my Linux system. for example: test@debian# i2cdetect -l i2c-0 i2c i915 gmbus dpa i2c adapter i2c-1 i2c i915 gmbus dpb i2c adapter i2c-2 i2c i915 gmbus dpc i2c adapter i2c-3 i2c i915 gmbus dpd i2c adapter i2c-4 i2c i915 DPDDC-C i2c adapter=20 i2c-0 to i2c-4 appears as well in /dev/ folders when I move to FreeBSD, doesn't matter what I did, i2C devices do not appea= r in Freebsd system, /dev/ folder does not include any of I2C controllers.=20 I use the same hardware under FreeBSD what I used under Linux. See details about my hardware below. My processor: Intel(R) Core(TM) i7-7500U CPU @ 2.70GHz (kaby lake) Internal video card HD Graphics 620=20=20 My FreeBSD version is 12.0, with last patches My kldstat just in case: Id Refs Address Size Name 1 82 0xffffffff80200000 243d1f8 kernel 2 1 0xffffffff8263e000 2da8 smb.ko 3 5 0xffffffff82641000 2e18 smbus.ko 4 1 0xffffffff82644000 3ca8 amdsmb.ko 5 1 0xffffffff82648000 4c98 iicbb.ko 6 6 0xffffffff8264d000 6cc8 iicbus.ko 7 1 0xffffffff82654000 8910 ig4.ko 8 1 0xffffffff8265e000 3950 iicsmb.ko 9 1 0xffffffff82662000 185c8 bktr.ko 10 2 0xffffffff8267b000 1530 bktr_mem.ko 11 1 0xffffffff8267d000 3820 iic.ko 12 1 0xffffffff82681000 6230 ichsmb.ko 13 1 0xffffffff82821000 12cc50 i915kms.ko 14 1 0xffffffff8294e000 767d0 drm.ko 15 4 0xffffffff829c5000 104f0 linuxkpi.ko 16 3 0xffffffff829d6000 12f30 linuxkpi_gplv2.ko 17 2 0xffffffff829e9000 6c0 debugfs.ko 18 1 0xffffffff829ea000 15630 if_iwm.ko 19 1 0xffffffff82a00000 10045f iwm7260fw.ko 20 1 0xffffffff82b01000 3aa0 ng_ubt.ko 21 2 0xffffffff82b05000 a020 netgraph.ko 22 1 0xffffffff82b10000 9608 ng_hci.ko 23 1 0xffffffff82b1a000 9c0 ng_bluetooth.ko 24 1 0xffffffff82b1b000 17590 smbfs.ko 25 2 0xffffffff82b33000 3050 libiconv.ko 26 2 0xffffffff82b37000 1dce libmchain.ko 27 1 0xffffffff82b39000 acf mac_ntpd.ko How you see, I had added a lot of useless modules, but they didn't help.
