GPU power management

[P. Souza]

Hello,

Anyone noticed any difference in power consumption or temperature when
enabling DynamicClocks in radeon(4) or ForceLowPowerMode in
radeonhd(4)?

I'm running -current (amd64 GENERIC.MP from Oct 20 snapshot) on a
Thinkpad T60 and the heat build up from the X1400 causes the fan to
change state (on->off or off->on) every 2 minutes or so, even when
idle. The fan seems to turn on arbitrarily between 50 and 55 degC
(which takes about 20 minutes when I first turn the laptop on), and
turn off between 45 and 48 degC.

There's a [new-ish] RB800. It's probably due to that.

Not that relevant but I thought I'd share my findings anyway.
According to some page I found(TM), the RB600 measured about 250 Mbps
on iperf on both debian and routerOS[1].

I was expecting more since the routerboard performance tests[2] show a
routing performance between 592-745 Mbps with 1500 byte packets. Even
so, seems like a nice alix substitute since, at least locally, the
price difference is negligible.

Has anyone tested the network throughput on these sweet little things?
