Hello,
I'm new to modern openbsd (having last used it in a router setting
back in 2000) and am trying to get the temperature sensor
for raspberry pi 4 working.
https://man.openbsd.org/bcmtmon seems to indicate it'd be in 6.8
but in dmesg there's nothing for BCM2711. What do I need to do
in order

Hi,
Can you try this in your system?
openbsdrpi4b2# sysctl -a | grep temp0
hw.sensors.bcmtmon0.temp0=55.99 degC
obsd# sysctl -a | grep temp0
obsd#

Set your uefi firmware to device tree or acpi + device tree mode.
ok thanks I'll try that and get back with results

Unfortunately neither of those modes worked. It sits at the part before it's
cleared the large raspberry image, after the first two lines of booting
output. Noth

In device tree mode serial output will be the default. You can switch
to HDMI (what we call glass console) by typing

Hi,
Would a not-working-with-devicetree-on-openbsd problem be something
I should be asking developers of the firmware about or asking
openbsd about?
The reason I'm asking is I'm trying to get the temperature sensor[1] working
and it seems I need devicetree to do that. Other than that,
ACPI works

Also note that support for the temperature sensor in ACPI mode was
added recently, after the 6.8 release.
Ah. I didn't fully appreciate this when I first read

Hi J,
Please try https://github.com/pftf/RPi4/releases/tag/v1.18. Haven't tried
the latest v1.22 firmware but for sure v1.19 and v1.20 crashed RPI 4B when
set to device tree mode.
Thanks for the tip, I'll try this.
I hope it'

Probably won't work as I don't think the older firmware supports the
8GB model.
aaah, ok.
No matter as having the 8GB is way more important than looking the
cpu temps. I'll wait until 6.9.
thanks,

Hello,
How would one measure the cpu speed for rpi4 under very recent
openbsd70 snapshot?
Is it kern.ccpu ? This returns 1948. Was looking for a descriptor
of that value too.
hw.cpuspeed returns "value is not available"
Under freebsd/current it's like this:
# sysctl dev.cpu.0
dev.cpu.0.te

Thanks
