I have 2 laptops as mentioned, 3 all amd athlon based. The
3rd is an asus which I'm relatively happy with.
What I have is when I pull the AC out of it, the sysctl for
cpu speed goes from 2200 to 100 or 400. Basically the system
becomes rather unusable.
I tried the acpi_hp module, and it now switches to 800. This
is better, but barely usable still.
I'd like to see a response similar to the asus if its
possible; this effectively stays the same, but drops speed if
nothing is happening.
Ideally, I'd think that it would be better if the system
adjusted speed to use requirements during operation, but
neither does that. I suspect that the asus should (in theory)
as it does do it on battery only; but unless I'm really
hammering all the time, it just doesn't seem to happen when
I'm looking at it.
The settings used on all for powerd is hiadaptive for AC,
adaptive for battery.
If I'm doing something wrong let me know, if more data is
required I'm happy to help the cause :)
TIA

I'd like to get this system running nicely if I can - its been
just getting there for too long now because of other projects
taking my attention and I've got bite the bullet and work this out.
BTW, just to make a liar out of me after I sent that post, the
system did start to change the cpu speed on AC - but it took a
while. I had sat there monitoring the system with little activity
and it remained at 2200; when I gave up waiting and sent that post
I then started to really give it to it and the speed started
dropping and rising a little. However, given I was trying to do an
encoding with ffmpeg at the time, the speed probably should have
remained at 2200 as my frames encoded per second was about half of
normal. So I don't really know what to expect :)

First, I suggest checking the output of kldstat to see that
acpi_wmi.ko is loaded.
See just above; that device is set with the module, and the module is
loaded with acpi_hp. Check:
kldstat:
8 1 0xffffffff8189f000 83c0 acpi_hp.ko
9 2 0xffffffff818a8000 7e10 acpi_wmi.ko
If not, add acpi_wmi_load=YES to loader.conf. wmi is an HP/Acer thing
and I really don't know much about it. Do you have powerd variables in
rc.conf? I assume you have powerd_enable="YES", but are you setting
any flags?
Flags as initially provided in OP: hiadaptive on AC, adaptive on battery.
I see that you are using P4TCC. (This is default in 10, but will
finally be fixed in 11.) You can turn it off by adding:
hint.p4tcc.0.disabled=1
hint.acpi_throttle.0.disabled=1
to loader.conf. It will remove a bunch of useless "frequencies" and
leave the useful values. It will make powerd much more responsive and
will prevent C-states from locking up the system when they are
enabled. I'd also suggest setting:
performance_cx_lowest="Cmax"
economy_cx_lowest="Cmax"
as C-states are by far and away the best power saving tool available.
(This also becomes default in 11.)
So what exactly should I be seeing? This:

dev.cpu.0.cx_lowest: C8

Why is it at c8? And what does the cx_supported do then?
For a lot of details on tuning power usage, read the article at
https://wiki.freebsd.org/TuningPowerConsumption.
Finally, so a little debug. Kill powerd (service powerd stop) and run
it with verbose on a terminal ("powerd -v" plus whatever options you
have in powerd_flags) and watch what powerd is doing.

So aside from being informative, how can this help me? You guys
mentioned locking up, was that happening each line here?
The -i and -r seemed reasonable for my purposes, so no change there, at
least until I get a better feel for things anyway.
With regards powernow! I can't see it in dmesg (used grep), but est
isn't used either as far as I can tell. How would I enable powernow in
freebsd anyway? Or is it just a cpu thing and not a module?
