Hi everyone!
This is followup on the https://marc.info/?t=147975430400002&r=1&w=2
thread from last November, I posted
https://marc.info/?l=openbsd-arm&m=147978035704263&w=2 inlined below.
Since, good ARM64 laptops have hit the shelves and you can pull a
Samsung Chromebook Plus for 300 USD or so. Very good laptop.
I wanted to enquire with you if anyone would feel like implementing
graphics support - binary blob-free, unaccelerated support would be
great but maybe blob-driven support could be fine too.
I'm not sure how the touchpad, wifi and power buttons are wired. The
RK3399 (aka OP1) doesn't have built-in wifi so that should be a separate
chip. Maybe it's all on USB.
OpenBSD does boot the RK3399, and missing is XHCI support (I presume
this means USB doesn't spin yet) and fixing the pmap bug (
http://marc.info/?t=149749938700001&r=1&w=2 ). Also missing is PCIe
support however would need to check if the Chromebook Plus' RK3399
actually has any device on its PCIe connectors.
If it would be of great value for you that someone donate you such a
laptop please say it and I'm sure some solution will show up.

Juan,
Re console:
Is there not even console graphics on the ARM boards yet, so only
serial interface?
Re X:
Using open-source drivers only, you can actually run X on the Mali
GPU:s (i.e. the chips in most ARM:s), unaccelerated.
Here's a video showing this on an EOMA68-A20 board in some Linux:
https://youtu.be/iM4cDjGY9vY?t=180 .
The low speed of the A20 CPU results in some flickering when switching
windows and tabs. I think on the modern ~2Ghz ARM:s e.g. RK3399, as
its single-thread and memory speed is approx 5x that of the A20, the
unaccelerated X should provide a perfect desktop experience (web
browsing, openoffice etc., anything except video decoding).
It would be super ultra cool to be able to do this on OpenBSD some day.

No, we don't have graphical support for the ARM boards yet.
Try with a "standard" (i.e. without special drivers) touch screen and
i386/amd64.
