UPS parcel containing MateBook

Back in December I made a joke in earnest that I only accepted thanks in the form of pizza or laptops, of course many people have graciously offered the former, I was not expecting the lengths of which someone would go to do the latter. And after many back and forths, trying as hard as I could to dissuade them (Shipping to Canada woes), they agreed to bring it with them to BSDCan 2019 and have it find its way to me!

UPS parcel containing MateBook
  • CPU: AMD Ryzen 5 2500U with Vega 8 - 4c/8t @ 2.0GHz
  • RAM: 8GB
  • SSD: 256G SandDisk M.2 SATA

What works!

Well, the keyboard backlight, as you can tell from above! But in addition to that, pretty much everything is supported by OpenBSD!

  • Wireless: Intel Dual Band Wireless-AC 8265 supported by iwm(4)
  • Touchpad: Elan ClickPad supported by both legacy pms(4) and ihidev/imt(4)
  • Touchscreen: Wacom I2C HID device, supported by ihidev/ims(4) in 6.7 -current (as of July 2020)
  • Audio: Dolby Atmos speakers sound great, supported by azalia(4), Realtek Codec
  • Webcam: uvideo(4) device, works with video(1) on amdgpu(4)
  • Power management: apmd_flags=-A seems to work
  • Accelerated X11/3D: amdgpu kernel drm driver has been committed to -current. Don't forget to # fw_update amdgpu
  • AMD SVM/vmd(8): Requires BIOS upgrade (1.22) to enable Virtualization setting.

What doesn't, or is untested

  • ACPI S3 (RAM): zzz(8) and lid suspend/resume works in -current (Jan 2020), will be in 6.7.
  • ACPI S4 (Hibernate): ZZZ(8) untested, should work?
  • Bluetooth: OpenBSD doesn't support it, so untested.
X using the wsfb(4) driver

My sincerest graditude to jsc/@grubernaut!, I finally own a laptop with a keyboard backlight!

And finally here's the dmesg, and also some bigger potatos.

If you liked this article, I'd sure appreciate a pizza. But only if you really want to! Okay. 🍕
