Stromsparen mit AMD Bulldozer

jmt · 23 Mai 2012

Hallo,

wie überzeuge ich denn meinen AMD FX davon, dass er nicht immer mit voller Leistung läuft? Der Powerd meldet immer:

Code:

hwpstate0: set freq failed, err 6

Sollte ich den Pwerd dann überhaupt noch verwenden? Reicht ein wechsel in den C2-State? Benutze ich C1E oder lieber nicht?
Kurzum: Ich bräuchte mal etwas Hilfe zu dem Thema. :confused:

Danke!

Also, das sind zwei Fragen auf einmal:

1. Deine Fehlermeldung sagt dir, dass powerd(8) - oder besser gesagt die Kernelseite hwpstate(4) - derzeit noch keinen Bulldozer unterstützt. Das ist, sagt der AMD-Fanboy, auch nicht zuletzt AMDs Schuld, da die Herren mit jeder Generation ihre verdammte Schnittstelle ändern müssen... Aber wie dem auch sei, es gibt gerade auf freebsd-stable@ einen Thread zu dem Thema: http://lists.freebsd.org/pipermail/freebsd-stable/2012-May/067560.html

2. AMD-Prozessoren haben zwei Arten von Powermanagement: Das klassische Intel-Powermanagement mit C0 bis C6 und C1E. Viele Boards schalten nur C1E frei, andere Boards fallen auf Intel zurück, wenn C1E deaktiviert wurde und wieder andere machen unverständliche Sachen. Der Unterschied zwischen den beiden Modi ist einfach, dass im Intel-Fall das Betriebssystem dafür verantwortlich ist, C0 bis C6 zu setzen. Die CPU setzt es nur dumm um. Bei C1E setzt das Betriebssystem nur C1 (deshalb sollte es die tieferen Powerstates auch gar nicht sehen) und die CPU entscheidet selbstständig, ob sie in einen tieferen Schlafzustand wechselt. Wenn beide Wege funktionieren, nehmen sie sich nichts. Wobei C1E den Vorteil hat, dass FreeBSD selbst keinerleich Konfiguration benötigt. Versagt der Intel-Weg, ist C1E logischerweise die Wahl.

Erst einmal Danke für die schnelle Antwort.

Wenn man dem angehängten Patch glauben schenkt, dann handelt es sich ja um eine Kleinigkeit. Werden denn auch alle Cores einzeln getaktet? Und versteht FreeBSD AMDs TurboCore?

Ich habe nun leider das Phänomen, dass ich C1E im Bios enabled habe und trotzdem FreeBSD einen C2-State sieht. Nachdem ich diesen gesetzt habe, scheinen die CPUs nun sich auch primär darin aufzuhalten. Was mache ich denn nun geschickter Weise? Schalte ich manuell auf C2 und C1E ab, oder lasse ich C1E eingeschaltet und lasse FreeBSD im C1 oder schalte ich C1E ein und setze FreeBSD auf C2? :confused:

Sofern der Patch das Problem denn behebt, ich wüsste ehrlich gesagt nicht, wieso er es tun sollte. Er macht dem Kernel lediglich den Bulldozer bekannt, was nicht einmal zwingend notwendig ist. Aber vielleicht braucht hwpstate(4) das, um irgendwelche Magie anzuwenden. Ansonsten werden Kerne (auf K10 und K12) einzeln getaktet, man sieht es allerdings nicht in den entsprechenden Sysctl. Sie zeigen immer die Taktung des Prozessors "0" an. Eine teure und für den Privatnutzer überflüssige Managementkarte gibt allerdings genauere Werte. TurboCore ist - genauso wie Intels TurboBoost - ein reines ACPI-Feature. Der Turbo taucht als eine weitere Frequenz auf, 1 MHz über der Maximalfrequenz. Also:
3400MHz -> CPU läuft 3400MHz ohne Turbo
3401 MHz -> CPU läuft auf 3400MHz und wirft wenn sinnvoll den Turbo an
Das Sysctl "dev.cpu.0.freq_levels" listet die verfügbaren Frequenzen und "dev.cpu.0.freq" setzt sie. Es kann allerdings sein, dass Bulldozer die Frequenzen nur dann rausrückt, wenn hwpstate(4) funktioniert...

Interessant... Was nun optimal ist, wird dir leider nur ein Energiesparmessgerät oder eine der sehr teuren AMD-Managementkarten sagen können, da wir leider nicht in die CPU reinschauen können. Im Zweifel würde ich allerdings C1E einschalten und C2 setzen. Das klingt rein vom Gefühl her am richtigsten.

Ach ja: powerd bringt auf modernen Prozessoren wie Bulldozer keine Wunder mehr. Die ernsten 98% ihrer Energieeinsparung durch Powergating, d.h. das Abschalten inaktiver Bereiche. Das funktioniert ohne jedes Zutun, C1E oder Intel-Powerstates unterstützen es aber. Ohne powerd braucht du vielleicht 2 oder 3 Watt mehr, was kein Beinbruch ist. Auch wenn es schön zu haben wäre.

Erst einmal ein großes DANKE für die ausführliche Antwort.

Heißt das dann, dass man keine Frequenzen mehr wechseln muss? Will sagen, ich schalte C2 und C1E ein und lasse die CPUs einfach auf 3400MHz laufen? Und machen die auch Turbo Core von alleine oder brauche ich dazu wieder den powerd?

Yamagi · 23 Mai 2012

Okay, mal stark vereinfacht erklärt (E-Techniker: Bitte nicht schlagen!): Früher, bis ca. 2003, funktionierten Prozessoren ganz einfach so, dass sie eine Taktfrequenz hatten und bei jedem Takt alle Transistoren schalteten. Dabei brauchte jeder Schaltvorgang Strom, entsprechend verbrauchten diese Prozessoren im Leerlauf kaum weniger Strom als unter Last. Mit steigenden Frequenzen wurde das aber zunehmend inakzeptabel, gerade der Pentium 4 stieß da in sehr unschöne Regionen vor. Daher führt AMD mit dem Athlon64 die Frequenzenskalierung aka "Cool and Quiet" ein, Intel zog später nach. Wenn weniger Rechenleistung benötigt wird, wird der Takt gesenkt. Daher schalten die Transistoren weniger und brauchen daher auch weniger Strom. Außerdem kann man die Spannung senken, was noch mal Einsparungen mit sich bringt. Relativ einfach und sehr wirksam, mein Athlon64 3200+ benötigt so z.B. ca. 45W weniger. Aber gerade für Mobilprozessoren war dies noch nicht genug Einsparung. Mit dem Core2 führte Intel daher "Powergating" ein. Dabei wird der Chip mit Millionen "Power Gates" durchzogen, die man sich wie Schalter vorstellen kann. Diese Schalter schalten alle Transistoren aus, die nicht benötigt werden. Im Leerlauf sind das fast alle. Ein aktueller Core i7 braucht so im Leerlauf weniger als 2W. Aber auch unter Last bringt Powergating deutliche Einsparungen, denn selbst unter Volllast arbeiten nur sehr wenige Teile der CPU parallel. AMD implementiert Powergating seit K12 aka Llano aka Fusion.

Da dank Powergating im Leerlauf kaum Transistoren aktiv sind, bringt das Senken ihres Takts und ihrer Spannung kaum mehr Einsparungen. Wenn powerd geht, ist es schön, denn 2 oder 3W sind da noch drin. Aber wenn es nicht geht, ist es kein Beinbruch mehr. Mache also C2 und C1E und sei vorerst glücklich.

Turbo (in Intels und AMDs Variante) ist eine rein interne Angelegenheit der CPU. Du setzt diese spezielle Frequenz 3401MHz (siehe oben) und alles weitere funktioniert automagisch. Das ist leider ein wenig doof, da man keine Möglichkeit hat zu sehen, ob er nun wirklich den Turbo zündet. Man kann es höchstens mit Benchmarks rausmessen. Auf meinem Core i7 2600k funktioniert er aber wohl, soweit man es halt sagen kann, einwandfrei.

EDIT: Das bezieht sich alles auf FreeBSD 9.0, unter 8.x ist der Turbo so eine Sache.

jmt · 23 Mai 2012

Da ich neugierig bin, habe ich meine Rechner vermessen. Die Ergebnisse sind sehr ernüchternd:

FreeBSD mit C1E / C2: 135W
OpenBSD mit apmd: 75W
Linux 3.3.6: 68W

Bei OpenBSD handelt es sich um einen der letzten Snapshots. Die 5.1 bootet nicht. Linux ist noch nicht mit powertop optimiert, aber mit voller CPU-Unterstützung.

jmt · 24 Mai 2012

Nachtrag:

FreeBSD C1E / C2 / powerd: 70W

Trotz obiger Fehlermeldung scheint der powerd ja ganz gut zu funktionieren. :cool:

hessijens · 24 Mai 2012

Er funktioniert, leider nicht immer, daher der Fehler. Wenn ich versuche die Frequenz mittels sysctl dev.cpu.0.freq=xy zu setzen funktioniert es, dann funktioniert es wieder nicht, grob geschätzt scheitert jeder 3. Versuch. Das Ganze ist unabhängig von der Frequenz und scheinbar völlig willkürlich. Irgend etwas scheint das Setzen der Frequenz zu verhindern. Siehe auch: http://www.freebsd.org/cgi/query-pr.cgi?pr=kern/167018

Yamagi · 24 Mai 2012

Hmmm... Irgendwie ist es unlogisch. Aber gut, Computer sind nun einmal nicht logisch... Es könnte natürlich sein, dass AMD das Pwergating beim Bulldozer irgendwie an die Frequenzskalierung gebunden hat. Aber das blind geraten. Ich hatte bisher leider nur Opterons in der Hand, die sich offensichtlich anders verhalten. Bzw. deren BIOS sich anders verhielt. Mal schauen, vielleicht kaufe ich eine "Trinity"-APU, wenn sie für den Desktop erhältlich werden.

Davon einmal abgesehen: Habt ihr einmal probiert powerd(8) mit "-v" auf einem Terminal auszuführen? Also als root "powerd -v" einzutippen? Das führt zwar zu extrem viel Ausgabe, aber vielleicht kann man ein Muster erkennen, wann er versagt.

Yamagi · 24 Mai 2012

Okay, das hilft schon einmal. Er bekommt also ab und an ENXIO (wird zu "Device not configured" übersetzt) zurückgegeben und manchmal nicht. Der Fehlercode wird von hwpstate(4) gar nicht so oft geworfen. Nun müssen wir nur noch herausfinden, an welcher Stelle der Fehler nun genau auftritt (blind geraten: hwpstate.c Zeile 178ff) und dann mit Hilfe von AMDs Doku schauen, was man dagegen machen kann. Da ich wie gesagt leider keine entsprechende CPU habe, muss ich aber noch mal weiter um Hilfe bitten:

Kannst du bitte in der /boot/loader.conf diese Optionen setzen

Code:

hint.acpi_throttle.0.disabled="1"
debug.hwpstate_verbose="1"

und rebooten? Danach nutzt du das System für einige Minuten ganz normal (mit laufendem powerd, damit er auch schon Frequenzen wechselt) und gibst mir dann die Ausgabe von "dmesg". Dort müssten am Ende jede Menge Ausgaben von hwpstate sein, aus denen man idealerweise herauslesen kann, was schief geht.

jmt · 24 Mai 2012

Ok, ist in Arbeit.

Code:

hint.acpi_throttle.0.disabled="1"

hatte ich eh schon gesetzt.

Yamagi · 24 Mai 2012

Danke dir

Es scheint tatsächlich so zu sein, wie ich vermutet hatte. In hwpstate.c hwpstate_goto_pstate() setzt er den neuen P-State. Das läuft vereinfacht für jeden Kern in drei Schritten ab:
1. Setze neuen P-State
2. Warte 100*100 Mikrosekunden und lese den aktuellen P-State aus.
3. Wenn "Gesetzer P-State != Aktueller P-State", gebe ENXIO.

Auf älteren Prozessoren (K10, K11 und K12) sind die 100*100 Mikrosekunden immer ausreichend. Bei K14 (Bobcat), K15 (Bulldozer) und wahrscheinlich auch K16 (Piledriver) steht in der CPU-Doku allerdings, dass auf diese 100*100 Mikrosekunden noch einige Dinge aufaddiert werden müssen. Oder anders gesagt sind die 100*100 Mikrosekunden ab und aus aus Glück ausreichend den Powerstate zu wechseln, oft aber nicht. Das führt dann dazu, dass hwpstate abbricht und einen Fehler zurückgibt, die CPU den Powerstate aber dennoch wechselt. Beim nächsten Versuch klappt es daher. Man sieht es in der Log gut:

Code:

# Wir setzen in P0, was klappt
hwpstate0: setting P0-state on cpu7
hwpstate0: result  P0-state on cpu7

# Die CPU ist in P0 und soll in P1
hwpstate0: setting P1-state on cpu0
hwpstate0: result  P0-state on cpu0
hwpstate0: error: loop is not enough.

# An dieser Stelle ist P0 gesetzt, obwohl P1 angefragt wurde.
# Grund ist, dass die CPU zu lange benötigt um P1 zu setzen.
# Er bricht mit einem Fehler ab, powerd macht daraus das
# verwirrende "powerd: error setting CPU frequency XXXX:
# Device not configured"

# Neuer Versuch P1 zu setzen, Da die
# CPU  dort inzwischen angekommen
# ist, denkt die Logik, sie hätte gerade
# P1 gesetzt. In wirklichkeit ist aber
# nichts passiert, wir sind von P1 auf
# P1 gewechselt.
hwpstate0: setting P1-state on cpu1
hwpstate0: result  P1-state on cpu1

Die Lösung ist nun, die Wartezeit zwischen Setzen und Prüfen einfach deutlich zu verlängern. Ich probiere es einmal mit 100*250 Mikrosekunden. Das ist wahrscheinlich übertrieben, aber viel hilft halt viel. Außerdem fügt der Patch noch die Option ein, die verfügbaren P-States auch auf aktuellen Prozessoren ohne ACPI auszulesen. Das sollte in der Praxis aber keine Rolle spielen, da diese neuen Systeme ohne ACPI eh nicht mehr funktionieren.

Nun musst du nur noch den Patch einspielen. Ich habe ihn auf meinem Phenom II 940 getestet, dort funktioniert er einwandfrei. Ich kann dir natürlich nicht versprechen, dass er keine böse Nebenwirkungen hat, ich wüsste aber nicht wie. Nachteile für die Hardware kann er definitiv nicht haben!

Code:

# Patch runterladen
% fetch http://deponie.yamagi.org/freebsd/patches/14h_15h_hwpstate.diff

# Patch einspielen (auf 9.0 und neuer)
% cd /usr/src/sys/x86/cpufreq
% patch < ~/14h_15h_hwpstate.diff

# Kernel neubauen
% cd /usr/src
% make -jN buildkernel
% make installkernel

Danach natürlich ein Reboot und bitte powerd noch einmal mit "-v" in einem Terminal starten. Dann einige Minuten ganz normal arbeiten und mir die Logs von powerd und das Ende der dmesg schicken. Idealerweise tauchen keine Fehler mehr drin auf und powerd arbeitet einwandfrei.

Yamagi · 24 Mai 2012

Immerhin haben wir einen Fehler eliminiert.

Ich schaue am Wochenende weiter...

jmt · 24 Mai 2012

Ich teste gerade mal, ob man mit 500 statt 250 weiter kommt.

Mist

Habe eine Debug vergessen!!!

Code:

debug.hwpstate_verbose="1"
[CODE]
Hole ich gleich nach.

Yamagi · 24 Mai 2012

Okay, noch ein kurzer Nachschlag: Die Fehlermeldung kommt nicht mehr aus hwpstate, stattdessen aus cpufreq selbst. Das bedeutet, dass ich noch einmal um eine dmesg betteln muss. Dieses Mal zusätzlich noch

Code:

debug.cpufreq.verbose="1"

in der /boot/loader.conf, danach wieder einige Zeit normal Arbeiten und dann hier rein... Wird wahrscheinlich noch mal eine große Menge Debug-Nachrichten bringen.

Yamagi · 24 Mai 2012

Nun haben wir uns überschnitten. Auch 500 oder sogar 1000 wird sehr wahrscheinlich nichts bringen... Da liegt irgendwo noch ein anderer Fehler. Ich vermute, dass es irgendwo in den Funktionen liegt, wo nach der Frequenzänderung kernelinterne Timer angepasst werden.

EDIT: Oder auch nicht, könnte auch ein durchschlagender Fehler aus hwstate sein. Aber schauen wir mal die nächste Log an.

jmt · 24 Mai 2012

So, folgende Infos mit Originalpatch:

jmt · 24 Mai 2012

Soll ich eigentlich ACPI wieder einschalten?

Yamagi · 24 Mai 2012

Ja, probiere mal.

EDIT: Die Logs sind nun mit meinem Patch mit 250?

jmt · 24 Mai 2012

Yepp! habe es gerade mal mit 500 versucht, aber er schaltet nicht mehr die Frequenz.

jmt · 25 Mai 2012

Hier mal ein anderer Versuch mit 100 Iterationen, aber einem Delay von 250. Leider führt das Logging immer noch dazu, dass der powerd die Frequenzen nicht schalten will. Warum startet er eigentlich bei 6200Mhz, also dem Doppelten der schnellsten Frequenz? Selbst mit Turbo Core schafft die CPU nur 4000MHz.
