What I ment was: enabling powerd in either hiadaptive or adaptive mode will eventually put the CPU to 1666 Mhz. However within a short timeframe, powerd stops downclocking the CPU when idle and the CPU stays at 1666 Mhz. If powerd is disabled after this, the CPU continues to stay at 1666 Mhz. The CPU isn't actually "stuck" at a specific clock per se (bad wording on my choice), but powerd kind of seems to be. If follow by starting powerd in min mode, it will change the frequence to the lowest possible succesfully. If I stop it and then restart again in hiadaptive or adaptive mode, the CPU again gets stuck at 1666 Mhz. - Dan ACPI dump available at: http://jago.pp.fi/x7spa-h.asl Note, however: acpidump -dt > x7spa-h.asl acpidump: RSDT entry 4 (sig OEMB) is corrupt OK, now I feel a bit stupid. The second half of my PR (anything related to powerd behaviour) can be ignored. For testing purposes, I started powerd in the foreground and observed it's behaviour. It works exactly as advertised and apparently the very act of issuing a "sysctl -a | grep dev.cpu.0.freq" command uses up a high % of CPU time for a fraction of a second, resulting in confusing output, I was always getting the highest cpu frequency state as the output. Testing powerd in foreground however, shows correct behaviour, CPU is downclocked both before and after issuing that command :) Still doesn't explain why the system boots up at 1249 Mhz, but that's not that big of an issue at this point now I see that powerd is behaving correctly. - Sincerely, Dan Naumov Responsible Changed From-To: freebsd-amd64->freebsd-acpi reassign. It's interesting question why the frequency at boot time is not the maximu frequency, but I suspect that it's more of a question to vendor/BIOS. Would you mind if I close this PR? -- Andriy Gapon On Sun, Dec 5, 2010 at 4:13 PM, Andriy Gapon <avg@freebsd.org> wrote: > > It's interesting question why the frequency at boot time is not the maximu > frequency, but I suspect that it's more of a question to vendor/BIOS. > > Would you mind if I close this PR? > > -- > Andriy Gapon > Go ahead. Sincerely. - Dan Naumov State Changed From-To: open->closed This doesn't seem to be a FreeBSD issue. |
In BIOS, the system sees the CPU at 1,66 Ghz frequency, which is the correct maximum frequency for an Atom D510 CPU. However, upon finishing the boot process, without any tunables, the CPU gets stuck at the wrong frequency: dev.cpu.0.freq: 1249 Mhz, severely degrading performance. Enabling and starting powerd and then putting the system under load will put the CPU to the correct frequency: dev.cpu.0.freq: 1666, however powerd seems to misbehave as well: After the initial frequency increase of the CPU to 1666 Mhz, the CPU gets stuck at this clockrate. Sometimes powerd will work correctly for a minute or so, correctly adjusting the CPU frequency according to load, but in a very short time, the CPU will get stuck at 1666 Mhz permanently (until reboot). Changing from "highadaptive" to "adaptive" mode in powerd settings seems to have no effect on this behaviour. System DMESG below: Copyright (c) 1992-2009 The FreeBSD Project.

Trying to mount root from zfs:cerberus/ROOT/cerberus em1: link state changed to UP Fix: As a workaround to getting stuck at 1249Mhz upon boot, the frequency can be manually adjusted.
