Kworker proces siluje višejezgreni procesor na laptopu

[Abzeenth]

Budući da je ovih dana popularno pisati na forumu kako Linux ima hrpu problema i nedostataka i kako će ga Windowsi ostaviti daleko iza sebe, ne smijem ni ja zaostajati za trendovima , pa odlučih iznijeti svoj veliki problem i zamoliti vas za pomoć.

Radi se o kworker procesu koji siluje procesor konstantnim I/O aktivnostima i time jaaako povećava temperaturu i potrošnju struje tj. baterije na laptopu. Problemi s tim procesom su se javljali i drugim ljudima (pisali smo o tome i na forumu), našla sam hrpu rezultata na netu na raznim distribucijama, verzijama kernela i hardverskim konfiguracijama. Nekim ljudima se riješilo prelaskom na novi kernel, neki su uspjeli raznim boot parametrima to popraviti, a nekima nitko nije odgovorio na postove pa su teme na forumima zamrle . Nadam se da se to neće dogoditi i meni

Svima je bilo zajedničko to da se problem javlja na višejezgrenim procesorima. Neki su imali mogućnost isključiti Hyperthreading u BIOS-u pa im je to pomoglo, međutim ja ne mogu, a nisam ni sigurna da je u tome problem. Laptop je Lenovo Z710 s Intel i5-4210M procesorom (Haswell). Imam i "hibridni" SSD i Intel+Nvidia grafiku s proprietary driverom, ali kako se ovaj problem javljao ljudima u raznim kombinacijama, opet mislim da možda i nije do grafike.

Što sam sve probala? Isss a šta nisam...
Isključiti irqbalance, promijeniti IO scheduler (noop i deadline, pa nazad na noop),
pcie_aspm=force u grubu, acpi_osi=Linux i Windows u grubu,
instalirati novi Intel microcode,
disejblati intel_idle u grubu s intel_idle.max_cstate=0,
promijeniti CPU freq scaling governor iz ondemand u powersave,
promijeniti procesor clocksource u hpet,
bootati s highres=off i nohz=off parametrima,
dodavati u grub noapic, nolapic, nolapictimer, acpi=noirq, pci=noacpi,
i instalirati stari kernel (sad imam 3.19.0-25-generic).

Ništa od ovog nije pomoglo.

Kworker se i dalje konstatno pojavljuje, a pregrijavanje i potrošnja ako se i jesu smanjili, to je bilo neprimjetno. Neke kombinacije acpi/noapic parametara su uzrokovale da wireless i backlight uopće ne rade, a nolapic uzrokuje da sustav ne vidi sve jezgre procesora, pa te opcije ionako otpadaju.

Probala sam gledati pojavljuje li se taj kworker dok sam samo u konzoli, znači kad nije pokrenut X, i sve je i dalje isto doslovno ništa ne radim na laptopu, a on drka po procesoru

Što još nisam probala?

Instalirati najnoviji kernel.
Bootati/instalirati neku novu distru (sad imam Mint 17.2).
Isključiti journaling i prebaciti sustav u writeback (ne znam zašto bi ovo uopće pomoglo).
Kompajlirati svoj kernel i postati Gentoo korisnik - doslovno sam na rubu da to napravim.
Dodati u grub parametre no_timer_check ILI apicpmtimer ILI notsc ILI nohpet.
Isključiti u BIOS-u AHCI support.
Instalirati nove drivere za Intel grafiku (opet, ne znam jel bi to pomoglo, ali vidjela sam da se javljaju neki i915 interrupti u powertopu, pa tko zna, možda upali).

"Rastavljanjem" tog procesa pomoću sudo eventstat -n i sudo perf -g -p $KWORKER_ID može se vidjeti što zapravo pokreće taj kworker proces. Ako nekog zanima, tu je perf screenshot. Eventstat i powertop pokazuju da preveliku aktivnost imaju hr_timer i neki tick_sched_timer. Pretpostavljam da su oni povezani s ovim što se vidi na perf screenshotu? Ima li to neke veze s tickless kernel postavkama, s raspodjelom "zadataka" na procesorske jezgre? Što još mogu ili trebam probati napraviti?

Ako ne znate odgovore na ta pitanja i uopće vas ne zanimaju screenshoti , onda vas molim samo za jednu stvar.

Ako imate laptop - nebitan proizvođač, ljudima se problem javljao i na Acerima, Asusima, Toshibama, Sonyjima, i Lenovu (kao i meni) - s višejezgrenim procesorom, molim vas pokrenite u terminalu sudo iotop -o i pogledajte ga par minuta, i recite mi pojavljuje li se i vama kworker proces. Kod mene se pojavljuje svake dvije sekunde, nekad "zastane" pa malo duže radi. Nije važno jeste li u idleu ili su vam pokrenuti neki procesi. Eto, najljepša hvala!

U terminal svake dvije sek. Ne primjećujem nikakvo silovanje procesora, temp u sobi je 34* a cpu-a 50*. Moraću još jednom pročitati tvoj post da shvatim o čemu se radi. Distra je openSUSE 13.2 KDE 4.14.9 .

javlja se kworker, ali uvijek je ispod 1 octo

Pogledaj ovo ako nisi. Drugo pametno nemam što više reći.

ne možeš se riješiti kworker procesa. To je generički process name holder za kernel i da isključivanje dotičnog znači isključivanje kernel procesa. Ono što tebe zanima je, ako si stvarno ultra sigurna da kworker proces generira te probleme, je vidjeti što točno generira takvo ponašanje. Recimo, zapisivanje na disk možda, (dstat, iotop), mreža (iptraf/iftop), te vidjeti što ti kaže atop kada ga pokreneš. Inače, isključivanje irqbalance samo usporava računalo i sigurno ga neće ubrzati.

Ono što me zanima je kakav ti je load na sustavu, koji je disk I/O te swap iskorištenost i koja je točno temperatura?

Znam za to, nema ništa strašno kod mene u .../acpi/interrupts. Ispis od cat /proc/interrupts je druga priča; meni izgleda užasno, a ne mogu procijeniti tj. odrediti u čemu je problem iz toga kad nemam s čime usporediti.

Da, kužim to, zato sam i pokušavala "rastaviti" ga s perf i eventstat naredbama.

Recimo, zapisivanje na disk možda, (dstat, iotop), mreža (iptraf/iftop), te vidjeti što ti kaže atop kada ga pokreneš. Inače, isključivanje irqbalance samo usporava računalo i sigurno ga neće ubrzati.

Uhm, pa jel nisi pročitao moj post? U iotopu je jedina aktivnost taj kworker proces, napisah da doslovno ništa ne radim i nemam pokrenut nijedan program osim terminala. A i kworker zapravo ne zapisuje ništa na disk, već samo radi I/O na procesor. Irqbalance sam vratila na kraju. Sve te postavke osim ondemand governora sam vratila onak kak su i bile, jer ništa nisu pomagale.

Ono što me zanima je kakav ti je load na sustavu, koji je disk I/O te swap iskorištenost i koja je točno temperatura?

S kojim parametrima da pokrenem atop? I u čemu želiš da ovo provjerim? Mislim da sam u zadnjih par dana instalirala sve dijagnostičke alate na svijetu pa više ne znam koji da koristim

Imaš li sve drivere? sudo lshw -html > hwinfo.htm
U dmesg nema nikakvih errora?
Probaj neku live distru jel se isto ponaša.

Probaj neku live distru jel se isto ponaša.

Budem. To je jedna od par stvari koje još nisam probala jer mi se ne da

[jurastublic]

Nekako mi se čini da si krenula od kraja a ne početka.
Prvo bih pogledao dmesg a onda instalirao novi kernel.
Ako to ne pomogne onda treba vidjeti koji je to proces u kworkeru. To možeš ovako:
Instaliraj perf:

Kod: Označi sve

sudo apt-get install linux-tools-$(uname -r)

Pokreni ga:

Kod: Označi sve

sudo perf record -g -a sleep 20

Pregledaj rezultat i onih prvih dvadesetak linija na vrhu kopiraj na forum (sa najvećim zauzećem procesora) :

Kod: Označi sve

sudo perf report

I par očenaša ne bi škodilo.

Jel ti se to dogadja otkad imas taj laptop ili je pocelo od nekog update-a?

Bilo je slicnih problema s noveau driverom, no buduci da si rekla da koristis proprietary, ne vjerujem da je do toga. No s powertopom mozes izolirati tocno sto uzrokuje kworkera da stalno radi (tak je bar opisano na prethodnom linku).

Takodjer, probaj bootati live verziju Linux Minta i vidjeti dogadja li se i tamo to zauzece procesora dok nis ne radis? Ako da, probaj bootati neku moderniju distribuciju, poput ArchLinux-a.

Kad kazes da procesor ima stalne I/O aktivnosti, jesi li sigurna da su te I/O aktivnosti bas usmjerene prema disku, a ne prema nekom drugom hardveru (bilo koja komunikacija procesora i svake druge HW komponente se smatra I/O, ukljucujuci mreznu komunikaciju, upravljanje grafikom, inputima, outputima, bluetoothom, USB uredjajima, itd.). To mozes provjeriti po stanju LED indikatora diskovne aktivnosti (on svijetli samo kod diskovnih aktivnosti). EDIT: tek sad sam vidio da si napisala da nemas diskovnih aktivnosti.

Takodjer, imas li u laptopu ustekan kakav USB uredjaj? Ja sam vise puta imao 100% I/O aktivnosti zbog pokvarenog USB diska (nisam ga mogao mountati ni unmountati ili bi ponekad mount prosao i onda nikako unmountati sto je uzrokovalo hanganje u kernelu toliko da je na kraju bio potreban hard reboot), a jednom mi se je slicno dogodilo i sa USB tipkovnicom.

I za kraj, ako imas dual boot s windowsima, probaj njih bootati i vidjeti dal i oni stekaju. Ako i oni stekaju, moguce da je nesto pokvareno u HW-u.

Npr. meni je SSD u laptopu riknuo na nacin koji je pokazivao dosta slicne simptome tvojima, ali puno drasticnije - dok god bih pazio koje foldere otvaram ne bi bilo nis problematicno, ali cim bi pristupio dijelu diska koji je valjda bio u pokvarenim celijama koje su zblesirale SSD kontroler sve bi se zamrzlo, ukljucujuci kernel pa sam morao napraviti hard reboot (kasnije sam taj disk stavio u USB kuciste da malo pomalo spasim podatke koji su se spasiti dali, no cim bi kontroler posandrcao, I/O bi skocio i sve je stalo - hard reboot ili ponekad nasilno vadjenje tog USB diska je znalo pomoci).
