Ib IRQ, luv luv rau Interrupt Request, yog siv nyob rau hauv lub computer kom xa raws nraim qhov-kev thov kom cuam tshuam CPU los ntawm ib co lwm yam khoom kho vajtse.

Lub Hom Phiaj ntawm IRQ

Ib qho kev thov cuam tshuam yog qhov tsim nyog rau tej yam xws li cov keyboard nias, nas txav, tshuab luam ntawv ua, thiab ntau dua. Thaum qhov kev thov yog tsim los ntawm ib lub cuab yeej kom nres lub processor, lub computer yog tom qab ntawd muaj peev xwm muab lub cuab yeej siv sijhawm los khiav nws txoj haujlwm.

Piv txwv li, txhua zaus koj nias tus yuam sij ntawm cov keyboard, tus neeg ua haujlwm cuam tshuam qhia tus processor tias nws yuav tsum tau nres qhov nws tab tom ua tam sim no kom nws thiaj li tuaj yeem tuav cov keystrokes.

Txhua lub cuab yeej sib txuas lus qhov kev thov dhau ntawm cov ntaub ntawv tshwj xeeb hu ua channel. Feem ntau koj pom IRQ hais txog, nws nyob nrog tus lej channel no, kuj hu ua IRQ tus lej. Piv txwv li, IRQ 4 yuav raug siv rau ib lub cuab yeej thiab IRQ 7 rau lwm tus.

IRQ yog hais raws li cov ntawv I-R-Q, tsis yog erk.

IRQ yuam kev

Yuav yuam kev cuam tshuam txog Kev Thov Kev cuam tshuam feem ntau tsuas yog pom thaum txhim kho kho vajtse tshiab lossis hloov chaw hauv cov khoom siv uas twb muaj lawm. Nov yog qee qhov yuam kev IRQ koj tuaj yeem pom:

IRQL_NOT_DISPATCH_LEVEL

IRQL_NOT_GREATER_OR_EQUAL

STOP: 0x00000008

STOP: 0x00000009

Saib yuav ua li cas kho STOP 0x00000009 yuam kev yog tias koj tab tom ntsib ib qho ntawm cov yuam kev ntawd (peb cov lus qhia zoo ib yam rau ob qho tib si).

Thaum nws muaj peev xwm ua tau rau tib lub IRQ channel siv rau ntau tshaj ib lub cuab yeej (tsuas yog ob qho tib si tsis tau siv tib lub sijhawm), nws ib txwm tsis yog li ntawd. Ib qho IRQ tsis sib haum xeeb feem ntau yuav tshwm sim thaum ob daim khoom kho vajtse sim siv tib lub channel rau kev thov cuam tshuam.

Vim tias Programmable Interrupt Controller (PIC) tsis txhawb qhov no, lub khoos phis tawj yuav khov lossis cov khoom siv yuav tsis ua haujlwm raws li qhov xav tau (lossis tsis ua haujlwm tag nrho).

Rov qab rau lub Windows thaum ntxov, IRQ yuam kev tau tshwm sim thiab nws tau siv ntau qhov teeb meem los kho lawv. Qhov no yog vim nws tau ntau dua los teeb tsa IRQ raws manually, zoo li nrog DIP keyboards, uas ua rau nws muaj feem ntau dua li ib lub cuab yeej siv tib IRQ kab.

Txawm li cas los xij, IRQs tau ua haujlwm zoo dua hauv cov tshiab ntawm Windows uas siv ntsaws thiab ua si, yog li koj yuav tsis tshua pom IRQ teeb meem lossis lwm qhov teeb meem IRQ.

Saib thiab hloov kho IRQ nqis

Txoj kev yooj yim tshaj plaws los saib IRQ cov ntaub ntawv hauv Windows yog nrog Tus Thawj Tswj Ntaus Ntawv. Hloov qhov View cov ntawv qhia zaub mov rau Resources los ntawm hom kom pom cov lus thov cuam tshuam (IRQ) ntu.

Koj tuaj yeem siv Cov Ntaub Ntawv Txheej Txheem. Ua qhov msinfo32.exe hais kom ua los ntawm Khiav lub thawv (WIN+R), thiab tom qab ntawd mus rau Hardware Resources> IRQs.

Linux cov neeg siv tuaj yeem khiav cat /proc/interrupts hais kom saib IRQ mappings.

Tej zaum koj yuav xav tau hloov IRQ kab rau ib lub cuab yeej tshwj xeeb yog tias nws siv tib IRQ ib yam li lwm tus, txawm hais tias feem ntau nws tsis tsim nyog vim tias cov peev txheej tau muab faib rau cov khoom siv tshiab. Nws tsuas yog laus dua Kev Lag Luam Standard Architecture (ISA) cov khoom siv uas yuav xav tau kev hloov kho IRQ.

How to Change IRQ Settings

Koj tuaj yeem hloov IRQ nqis hauv BIOS lossis hauv Windows ntawm Tus Thawj Tswj Ntaus Ntaus. Nov yog yuav ua li cas hloov IRQ nqis nrog Tus Thawj Tswj Ntaus Ntaus:

Nco ntsoov tias kev hloov pauv tsis raug rau cov teeb tsa no tuaj yeem ua rau muaj teeb meem uas koj tsis tau muaj ua ntej. Xyuas kom koj paub tias koj tab tom ua dab tsi thiab tau sau ib qho kev teeb tsa thiab cov txiaj ntsig uas twb muaj lawm kom koj paub tias yuav rov qab mus rau qhov twg yog qhov tsis raug.

Qhib Device Manager.
Ob-nias lossis ob-kais ib lub cuab yeej qhib nws lub qhov rais Properties. Koj yuav tsum qhib lub ntaus ntawv qeb ua ntej koj yuav pom nws, uas koj tuaj yeem ua tau los ntawm ob npaug nias / tapping.
In the Resources tab, deselect lub Siv tsis siv neeg nqis kev xaiv.

Yog tias koj nrhiav tsis tau lub tab no lossis qhov kev xaiv yog greyed los yog tsis tau qhib, nws txhais tau hais tias txawm koj tsis tuaj yeem qhia cov peev txheej rau cov cuab yeej ntawd lossis cov cuab yeej tsis muaj lwm qhov chaw uas tuaj yeem siv rau nws.
Siv lub Settings raws lipoob cov ntawv qhia zaub mov xaiv cov khoom kho vajtse uas yuav tsum tau hloov pauv.
Xaiv IRQ los ntawm Resource settings thaj chaw ntawm cov khoom.
Siv lub Hloov Chaw khawm hloov kho tus nqi IRQ.

Common IRQ Channels

Ntawm no yog qee yam ntawm IRQ channel ntau dua siv rau:
