Back in December of 2023, I put out a request on social media for a laptop that supported the PKU (xonly) and IBT (Indirect Branch Tracking) features, used to implement ROP mitigations, that are found (together) only on recent Intel CPUs...

ThinkPad running OpenBSD 7.5 -current KDE6
... this request was answered by a very generous person in April of 2024. Hooray!
  • CPU: 11th Gen Intel(R) Core(TM) i7-1165G7 @ 2.80GHz x4 (SMT off)
  • RAM: 16GB
  • SSD: 512G Samsung PM9B1 M.2 NVMe
  • LCD: 13.3" IPS, 1080p

What works!

So far, I've tested the following running 7.5 -current (As of August 2024)!
  • Wireless: Intel Wi-Fi 6 AX201 (CNVi) supported by iwx(4)
  • Touchpad/TrackPoint: Elan ClickPad (version 4, firmware 0x5f3001) supported by pms(4), TrackPoint and physical mouse buttons work
  • Touchscreen: Works by default, USB uhidev(4) "ELAN Touchscreen"
  • Audio: azalia(4) device, Realtek ALC257 codec
  • Power management: apmd works
  • Accelerated X11/3D: inteldrm(4) works, VA-API hardware video works with intel-media-drivers package
  • ACPI S3 (RAM): Linux S3 in BIOS, zzz suspend/resume works

What doesn't, or is untested

  • ACPI S0i (Suspend-to-Idle): Untested, but should be supported in -current/7.6
  • Thunderbolt 4: Untested, but PCIe tunneling needs to be disabled in the BIOS or Type-C charging breaks
  • Ethernet: Requires Lenovo proprietary dongle
  • Webcam: uvideo(4) device, should work but untested, Thinkshutter switch for privacy.
  • VMX/vmd(8): Untested, but should work, vmm(4) shows up in dmesg
  • Bluetooth: OpenBSD doesn't support it, so untested.

And here's the dmesg!

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