Hi I have a Lenovo Ideapad Miix 310 that has a Intel CherryTrail CPU and it runs FreeBSD quite nicely (with accelerated graphics). What I'm missing is battery life status.. I can get this information using smb (for some reason i2c just returns error sending start condition) smbmsg -f /dev/smb6 -s 0x68 -c 0xB9 -i 1 -F %d In emergency this works but it would be nice to have a kernel driver for it. I found the axp2xx driver for Allwinner in the tree. Would it be possible to share this with amd64 with not too much effort? If not, all I'm really interested in is battery status so I might just hack together a simple driver for that report values to hw.acpi.battery (because I don't think there is a sysctl for battery info that aggregates different sources?) Datasheet for the pmic can be found here http://download.bbs.ickey.cn/201707/cfe88ee7ef01eed7a4586ce340165da0.pdf Cheers
