Hello,
Maybe my e-mail client is messing with me, but I couldn't find any
dmesg
output
attached to your e-mail. Could you please try to attach it again?
By the way, since you have a Kepler, you should try booting with
"nouveau.War00C800_0=1". That workaround is enabled by default in
4.4-rc5
(IIRC), but that might not be the case on Karol's branch.
Best regards,

I did not find that parameter under /sys/module/nouveau/parameters.
Google led me to try nouveau.config=War00C800_0=1 instead.
Anyway, I added both to the kernel cmdline. Unfortunately it made no
difference. Dota 2 still freezes up the system pretty much
immediately
(when 0f pstate is in use).
well so that means that it doesn't freeze when not using 0f?
That's right.
I suspect that nouveau currently just sets the voltage too low, but
this is
another issue
and this issue will be tackled next year.
You could replace info.min with info.max in
drm/nouveau/nvkm/subdev/volt/base.c:nvkm_volt_map
but this will result in more heat generated by your gpu and nouveau
currently
does not verifies if the
ovearheating protection is setup sanely (though it should be setup
already by
the gpu itself)
What's your recommendation to determine suitable values? I could try the binary
driver under Linux or win10. Under win10 I know some tools (e.g. msi
afterburner). Note that I know next to nothing about the Kepler architecture
itself, just the basic voltage-frequency-temperature interactions.
Just a follow up. Your suggestion worked fine for me. Should this change
be merged?
Best regards.
