OpenBSD on Pinebook - improving user experience - elewarr - 08-10-2019
Hello!
Some time ago I bough A64+, then had a chance to buy Pinebook.
The plan was to run OpenBSD on both and get involved in driver development.
I maintain a few patches to OpenBSD (slowly trying them to be upstreamed).
But the code needs modified device tree, so my second repo is u-boot related (but also it's just an addition to OpenBSD's u-boot port).
Repositiories:
1. u-boot additions: https://github.com/elewarr/openbsd-ports-u-boot
2. OpenBSD src patches: https://github.com/elewarr/openbsd-arm64-src-dev
Please note, these repositories have instructions to help you get involved (with some scripts that are not very reliable but fulfil basic needs).
Status:
1. sxitemp, sxisid
sxitemp driver relies on sxisid and uses calibration data, providing accurate temperature readings.
2. sxiuphy
This driver (provided by Patrick Wildt) enables 2nd USB port is disabled by default for now because of unsolved issues on A64+, uncomment sxiuphy in GENERIC config to enable.
3. sxiccmu
Enables dynamic CPU frequencies.
4. axppmic
Supports more PMIC sensors. Current battery capacity, voltage, dis/charging current.
Work in progress:
1. sxipwm
OpenBSD does not have PWM framework but this is needed for
2. pwmbl
PWM backlight driverThe idea is to provide basic support for wsconsctl brightness property using PWN and generic PWM based backlight driver.Current status: brightness is set to max at boot.
I was eager to get my hands on Pinebook Pro but because of some technical issues I failed to get my voucher in time. Maybe I'll have more luck in the future. I'm aware this work (focused on Pinebook) may not be useful for Rockchip ICs but I want to learn something and this is a lot of fun!
Booting with the full brightness, yay!

Good news!
axppmic is now in the official repository, thanks to Mark Kettenis.
It needs device tree to contain (it's not yet in my u-boot repository):

Thanks, I will try out on this weekend :-)
