There's still a lot of unrecognized devices on the P1 Gen 3, and the
install process is not quite smooth yet, but it does eventually boot
once installed with a GENERIC* kernel from -current. (See
https://marc.info/?l=openbsd-bugs&m=160011933402270&w=2 for dmesg and
vitals from the unmodified kernel.)
The audio device seems compatible with azalia, but I haven't done a
lot of thorough testing: adding the device ID to be detected for the
driver means audio-out works.
The laptop comes with an AX201 card for networking, but the PCI device
ID is unrecognized. iwx has a TODO mentioning the 06f0 ID, which this
one has. Fudging iwx to accept it seems to work OK, but is a little
buggy. Specifically, noticed slowness to acquire DHCP lease and things
can get wedged in exceptional circumstances such that the iwx device
becomes undetectable unless a full power cycle is taken. I haven't yet
fully reproduced the latter issue, nor eliminated local effects for
the DHCP problem.
Ultimately, this all may not be correct, but it does make the devices
sort of usable. FWIW, here's the diff.
