Keyboard and trackpad nonfunctional on Acer CB3-431

[lorddimwit]

I have an Acer CB3-431 Chromebook, flashed with UEFI firmware from ​https://mrchromebox.tech.

I can boot Haiku (both Alpha 4 and nightly) off of a USB drive without any problems. Hardware support is pretty good, for the most part:

• Graphics work great
• Internal WiFi works fine
• Sound appears to work

The missing hardware is:

• Internal storage is not detected
• The keyboard and trackpad do not work

The keyboard is especially interesting: it doesn't work, *except* in KDL. If I trigger a kernel crash (by removing the USB I booted from and then reinserting it), I am dropped into KDL and the internal keyboard works. I'm not sure why the keyboard would work in KDL but not normally.

A USB keyboard works, but hitting shift/space does not interrupt the bootloader, so I'm not able to do anything like boot into safe mode.

I've attached the output of listdev and the syslog; please let me know if you need anything else. I really appreciate what you've done with Haiku, thank you for your help!

KERN: ps2: keyboard reset failed, status 0x80000009, data 0xff
KERN: ps2: keyboard getid failed, status 0x80000009, data 0x0000. Assuming no keyboard
KERN: ps2: keyboard probing failed
USER: Notify of added/removed/started/stopped device
Last message repeated 1 time
KERN: KeyboardDevice: error when opening /dev/input/keyboard/at/0: General system error
KERN: ps2: devfs_unpublish_device input/keyboard/at/0, status = 0x00000000

So, the keyboard reset fails, and then we assume there's no keyboard. But apparently there is one, because the KDL code to handle PS/2 interrupts clearly works. So I wonder what's going wrong here?

To confirm: the same thing happens on beta4 and nightlies (i.e. no keyboard and you see similar lines in the syslog)?

Those logs are from the nightly build from a couple of days ago.

The behavior is the same on Alpha 4 though I don’t recall if the syslog was the same. I can boot up Alpha 4 later tonight and let you know, though I’m willing to bet it’s the same.

I searched the web a bit, it seems Linux had trouble with these machines as well, and requires CONFIG_PINCTRL_CHERRYVIEW=y to do some configuration of IO ports before the PS2 controller can fully work.

Since KDL works, I assume it is "almost working" and maybe it's just the interrupts that are not getting delivered or something like that.

This is mentionned here for example: ​https://bbs.archlinux.org/viewtopic.php?id=213852

FreeBSD also seems to have various quirks for these machines because the keyboard controller is not behaving exactly like in a normal PC:
