Thanks, the C720 is mentioned in that file.

The manual page actually exists... but only in the source code :-(
share/man/man4/chromebook_platform.4
Mea culpa.

You can look through this Linux source file to check for information that's
relevant to your laptop:
http://lxr.free-electrons.com/source/drivers/platform/chrome/chromeos_laptop.c

Also, could you please provide pciconf -lv output?
Thanks!

cyapa(4) and isl(4) no longer working on Acer C720

2017-02-25 Thread Wolfgang Zenker 
Hi,

I'm using FreeBSD 11 on a chromebook Acer C720. Because I normally
use a mouse I didn't catch the exact time when cyapa and isl stopped
working, but my guess is it was when chromebook_framework was introduced
and cyapa and isl were moved to using iic. 

A manual page chromebook_platform(4) does not exist. Maybe the Acer is
sufficiently different from other chromebooks that chromebook_platform
does not work here. In that case I'm supposed to set device hints for
the isl and cyapa drivers where to find their iic resources, according
to 
https://github.com/freebsd/freebsd-base-graphics/commit/e2eab8e254154d36ebd6fde573f86e6472b75572
Unfortunately I have no idea where to find the information that would
be needed for this.

I have this in /boot/loader.conf:
-
kern.geom.label.disk_ident.enable="0"
kern.geom.label.gptid.enable="0"
zfs_load="YES"
coretemp_load="YES"
chromebook_platform_load="YES"
ig4_load="YES"
cyapa_load="YES"
isl_load="YES"
-

And this in /etc/rc.conf:
-
hostname="faunus"
keymap="de"
kld_list="i915kms.ko"
sshd_enable="YES"
dumpdev="AUTO"
zfs_enable="YES"
wlans_ath0="wlan0"
ifconfig_wlan0="WPA DHCP country de"
ifconfig_wlan0_ipv6="inet6 accept_rtadv"
rtsold_enable="YES"
moused_enable="YES"
moused_port="/dev/cyapa0"
ntpd_enable="YES"
ntpd_sync_on_start="YES"
-

Kernel config is GENERIC with added options DDB, GDB, WITNESS
and WITNESS_SKIPSPIN.

This shows up in /var/run/dmesg.boot:
