Ohne Debug-Ausgaben im Kernel schaltet der Powerd endlich wieder:

Das Aktivieren bzw. Deaktivieren von debug veraendert real das Verhalten? o_O

Yamagi · 25 Mai 2012

So, ich habe mir gerade alles noch einmal angesehen. Erst einmal vergesse, was ich gestern Abend sagte. Tatsächlich wird der "hwpstate0: set freq failed, err 6" zwar durch cpufreq(4) geworfen, hat seinen Ursprung aber ebenfalls in hwpstate(4). Da nach der Doku (zumindest so, wie ich die wirre Beschreibung verstehe) der vorhandene Code korrekt ist, habe ich noch einmal einen Blick zur Linux-Fraktion geworfen. Sie haben zu unserem Code einen kleinen aber feinen Unterschied: Sie warten nicht einfach 100*100 Sekunden und hoffen, dass der Kram korrekt gesetzt wird. Sie setzen ihn stattdessen bis zu 100 Mal neu. Ich habe die Logik entsprechend angepasst und außerdem mehrere Debugausgaben eingefügt. Der Patch ist noch mit diversen Anmerkungen vollgekleistert und entspricht nicht mal im Ansatz style(9), aber wir wollen nun erst einmal schauen, ob es funktioniert.

Der Patch: http://deponie.yamagi.org/freebsd/patches/14h_15h_hwpstate_v2.diff

Der Patch ist gegen die unveränderte hwpstate.c. Du müsstest also zuerst ein "svn revert" auf die Datei machen, "csup" erneut laufen lassen oder das von patch(1) angelegte Backup zurückkopieren. Je nach dem...

Es wäre nett, wenn du einmal ohne Debugausgaben schauen könntest, ob es nun funktioniert. Aber egal ob es das tut oder nicht, würde ich gern noch eine dmesg und eine Ausgabe von "powerd -v" mit den beiden Debugoptionen (für cpufreq und hwpstate) sehen. Schon um eventuelle Fehler ausschließen zu können. Auf meinem Phenom II funktioniert es auch mit dem Patch einwandfrei, aber das hat nicht viel zu sagen.

Jo, die Debugausgabe erzeugt CPU-Last und wenn powerd(8) zu empfindlich eingestellt ist - und genau das ist er im Standardprofil - taktet er durch die Debugausgabe sofort wieder hoch, wenn er versucht runterzutakten.

Cool, das sieht spannend aus. Ich habe auch einen Bulldozer (FX-8120) und werde das kommende Woche durchtesten mit deinem Patch. Mein Strommessgerät hat leider den Geist aufgegeben, aber nächste Woche sollte das neue da sein.

Ich weiß noch, bei mir ging's von etwa 110-120 Watt auf etwa 75 Watt runter mit dem Verbrauch, seit ich powerd gestartet hatte. Allerdings weiß ich nicht, ob C1E an ist und werde da auch erst mit neuem Strommesser rumspielen (sonst ist's nur raten).

Die schlechte Nachricht ist, dass es immer noch nicht tut. :mad:

Die gute Nachricht ist, dass es besser geworden ist.

Zu den Fakten: Dmesg nach Systemstart mit ACPI und ohne Debug:

Interessanter Weise startet der Powerd mit Debug bei der doppelten Frequenz. Ist das gewollt?

Ja, das scheint korrekt zu sein. Das macht er sowohl auf meinem Core i7, als auch auf dem Phenom ebenfalls so. Darin würde ich nun erst einmal kein Problem sehen.

Code:

hwpstate0: MSR: 0 ID: 1
hwpstate0: Setting failed!
hwpstate0: Iterationen: 102
hwpstate0: setting P1-state on cpu1
hwpstate0: MSR: 1 ID: 1
hwpstate0: Iterationen: 1
hwpstate0: setting P1-state on cpu2
hwpstate0: MSR: 0 ID: 1

Hier sieht man gut, was nun noch verkehrt läuft. Er versucht 102 Mal die neue Frequenz zu setzen, da es nicht klappt, bricht er ab. Als er es kurz darauf allerdings wieder probiert, klappt es dann auf einmal auf magische Weise. Die große Frage ist nun: WARUM? Vom Gefühl her würde ich sagen, dass man den P-State des Bulldozer in gewissen Zuständen einfach nicht wechseln kann. Jedoch ist mir unklar, wann das auftritt.

Es gibt nun 2 Möglichkeiten:
1) Die Abbruchbedingung unter "if (y++ > 100)" entweder rausnehmen, oder statt 100 es mit noch mal drastisch höheren Werten probieren. Ich fände es aber gar nicht gut, da ein Rausnehmen zur Endlossschleife führen kann (das System friert ein oder man bekommt einen schönen Live-Lock, bei dem das System teilweise einfriert) und ein deutliches verlängern sicher Performanceeinbußen mit sich bringt.
2) Den hwpstate(4) so umbasteln, dass er wie der Linuxtreiber nicht einfach einen P-State reinwirft, stattdessen eine "Frequency-ID" und eine "Voltage-ID" ausrechnet und getrennt setzt. Das hätte den Vorteil, dass man sicher noch einige Milliwatt mehr rausgequetscht bekommt, verlangt aber umfangreichere Änderungen am Code als ich blind hinbekommen kann.

Daher wäre mein Vorschlag, dass ich unsere Erkenntnisse, den Patch und deine Log (sofern du einverstanden bist) zu einen Mailinglist-Post zusammenfasse und an freebsd-stable@ schicke. Mit ein wenig Glück weiß einer der ursprünglichen Autoren des Treibers, woran es klemmt. Außerdem werde ich das Wochenende über noch einmal nachdenken, ob mir nicht noch etwas einfällt. Bis Sonntag Abend komme ich sowieso nicht an meinem Phenom ran und kann daher nichts machen. Auf beiden Augen blind zu coden geht im Kernel fast immer schief.

jmt · 25 Mai 2012

Sehr gutes Vorgehen. Meine Logs kannst Du natürlich verwenden. Noch eine Interessante Sache nebenbei: Wenn ich den Rechner mit Deinem Patch betreibe, dann braucht er 7-8 Watt mehr im Idle als in der Originalfassung. Dabei meine ich eine Idle-Time im Stundenbereich (Keine Ahnung, ab wann das genau zutrifft).

Yamagi · 25 Mai 2012

Die Mail ist raus. Sollte in einige Minuten im Web-Archiv auftauchen. Mal schauen, was dabei rauskommt...

Der Mehrverbrauch kann schon daher kommen, dass wir durch die Debugausgabe und das deutlich häufigere Setzen des neuen P-State den Mechanismus unterlaufen.

Yamagi · 26 Mai 2012

So, es hat sich nun folgendes ergeben: Wenn man auf einem alten K10 Phenom den P-State setzt, wird er sofort übernommen und im Status-Register wiedergegeben. Ein Bulldozer hat jedoch diese "Computation Units" aka "Module", die jeweils zwei Threads bereitstellen. Das Betriebssystem sieht in den Threads normale Kerne. Wenn man den P-State für einen dieser Kerne setzt, wird er erst im Status-Register wiedergegeben, wenn beide Kerne des Moduls umgeschaltet haben. Und das kann einige Zeit dauern. Andriy Gabon schlägt nun vor, einfach die Überprüfung in den Zeilen 187 bis 202 der ungepatchen hwpstate.c zu entfernen. Das sollte sicher sein, da die CPU in jedem Fall früher oder später in den neuen P-State wechselt. Jung-uk Kim meint hingegen, dass wir erst einmal probieren sollten, ein anderes Register auszulesen, was den gesetzten aber noch nicht übernommenen P-State angibt. Wenn es funktioniert, ist es gut. Wenn nicht, können wir noch immer die Prüfung einfach entfernen. Ich werde diese Lösung Anfang nächster Woche implementieren und einen neuen Patch liefern.

jmt · 26 Mai 2012

Ich habe die Diskussion auch verfolgt und eine neuen Patch gebaut. Dabei setze ich erst alle P-States und überprüfe danach, ob der P-State erreicht wurde. Das funktioniert ohne Fehlermeldungen.

So, mittlerweile habe ich einen zusätzlichen Stromfresser ausgemacht. Die 6-8 Watt Differenz bei den Patchen (Zeitweilig sogar 10) kommen durch folgenden Eintrag in der loader.conf:

Code:

hint.acpi_throttle.0.disabled="1"

Mit abgeschalteten ACPI liegt der IDLE-Verbrauch bei 68-70W und in der "normalen" Einstellung mit ACPi bei 75-80W. Irgendwie kann das ja auch nicht im Sinne des Erfinders sein? :confused:

Yamagi · 27 Mai 2012

Guten Morgen

Das ACPI-Throtteling negativ ist, ist bekannt. Mir ist allerdings nicht ganz klar, woran es liegt. Es gab vor längerer Zeit auch schon mal eine Debatte, ab man die Standardeinstellung nicht besser auf "aus" ändern sollte. In die gleiche Richtung geht übrigens auch "P4TCC". Es sollte zwar auf AMD-CPUs nicht greifen, aber du kannst natürlich trotzdem probieren es abzuschalten:

Code:

hint.p4tcc.X.disabled=1

Wobei du eine Zeile für jede CPU brauchst, und X durch die Nummer der CPU ersetzt.

Auch powerd hat selbst noch Einsparpotential. Das Standardprofile "Highly Adaptive" ist sehr nervös. Es taktet bereits bei geringer CPU-Last sehr aggressiv hoch und bei abfallender CPU-Last nur langsam wieder herunter. In den meisten Fällen ist das konservativere "Adaptive"-Profil die bessere Wahl. Damit taktet die CPU langsamer hoch und schneller runter, was auf Desktops kaum merkliche Nachteile hat.

Yamagi · 27 Mai 2012

Zu den Patches: Ich habe nun noch einmal ein wenig im Developer Guide gelesen. Es gibt Argumente für beide präsentierte Ansätze. Für Andriy Gabons Patch spricht, dass er sehr einfach ist und funktionioniert. Für Jung-uk Kim Patch spricht wiederum, dass er ohne ein DELAY() auskommt und insgesamt korrekter erscheint. Allerdings verlangt er eine vergleichsweise komplizierte Logik, um CPUs mit Hardware P-States (wie Bulldozer) von älteren CPUs ohne Hardware P-State zu unterscheiden.

Yamagi · 27 Mai 2012

Und ein dritter Post. Wir müssen ja den Post-Count hochtreiben... Könntest du bitte noch einmal Andriys Patch ausprobieren? Das ist genau das gleiche, was du in deinem Patch machst und sollte daher auch funktionieren, aber ich würde gern zu 100% sicher gehen. Falls du die Mail nicht bekommen hast (ich sehe sie irgendwie nicht im Archiv), ist er hier:

Code:

Wenn er funktioniert, würde ich schreiben, dass er die bessere Lösung ist, da er nur eine triviale Änderung darstellt und ihe viel weitere Logik auskommt.

jmt · 27 Mai 2012

Habe den Patch eingespielt und er funktioniert. Wenn ich das richtig verstehe, dann werden aber alle Kerne gleich getaktet. Das ist natürlich nicht optimal, aber wahrscheinlich eine viel größere Änderung.

Yamagi · 28 Mai 2012

Okay, dann nochmal danke. Ich werde heute Abend noch einen Testlauf auf meinem Phenom II machen und dann die nächste E-Mail schreiben. Das mit den unterschiedlichen Taktraten ist so eine Sache. Es gibt diese Managementkarten, die man in einem PCI-Slot steckt, dann interne Register auslesen und auf einer schlechten LED-Anzeige darstellen. Wir hatten für die Firma mal eine gekauft, da wir recht viel AMD verbauten und hofften, damit Probleme schneller diganistizieren zu können. Am Ende war es aber eine Fehlinvestition, auch wenn man sehen konnte, was verkehrt lief, war kaputt dennoch meist kaputt. Diese Karte zeigte unter FreeBSD unterschiedliche P-States für die Kerne an, dem Code nach wurden aber noch nie unterschiedliche P-State gesetzt! Mein Tipp ist, dass die Schleife zum Prüfen nach dem Setzen eines P-States die Karte verwirrt hat. Kern 1 war z.B. schon P2, Kern 1 aber noch P1 und so weiter, durch geringe Ausleseintervalle blieb es denn für einige Zeit so angezeigt. Ich teste nachher mal, was sie mit dem Patch, der ja erst alle Kerne setzt und dann prüft, anzeigt. Ich stimme dir zu, dass Setzen unterschiedlicher P-States für einzelne Kerne cool wäre, aber das geben im Moment weder cpufreq noch powerd her.

jmt · 28 Mai 2012

Wäre es denn "einfach" möglich die verschiedenen Frequenzen der Cores als sysctl herauszuführen? Der Nachteil nur einer Frequenz für alle CPUs besteht ja u.a. darin, dass TurboCore nicht richtig greifen kann. Hierbei kommt es auf die gesammte verbrauchte Energie an, bzw. dass möglichst viele Cores schlafen. Das sollte bei Intel ähnlich sein.

Yamagi · 29 Mai 2012

So, ich habe nun noch einmal an die Mailingliste geschrieben. Wahrscheinlich wird die Diskussion noch weitergehen, aber unser Teil daran ist nun erledigt.

Yamagi · 29 Mai 2012

Zum Turbo: AMDs TurboCore richtete sich nach aktuellen Stromverbrauch. Umso mehr Kerne tief schlafen, umso größer ist die Wirkung. Es wäre daher wünschenswert, wenn man die Kerne einzeln takten könnte, aber leider gibt cpufreq(4) das derzeit einfach nicht her. Und ich bezweifele, dass es so schnell jemand anbauen wird...

hessijens · 30 Mai 2012

Ein dickes "Danke" an Yamagi, es funktioniert nun bei mir auch einwandfrei, und ich habe zudem wieder einiges dazugelernt.

jmt · 30 Mai 2012

Dem schließe ich mich direkt an!
