Multikernel projekti arendajad, mis v\u00f5imaldab \u00fchel f\u00fc\u00fcsilisel arvutis mitme s\u00f5ltumatu tuuma eksemplari k\u00e4itamise ilma h\u00fcperviisori ja virtualiseerimiseta, esitasid kmorph t\u00f6\u00f6riistakomplekti, mis rakendab meetodeid Linuxi tuumade kiireks taastamiseks p\u00e4rast t\u00f5rkeid v\u00f5i tuuma asendamiseks Live-re\u017eiimis ilma t\u00e4iemahulise taask\u00e4ivitamiseta. Projekti juhib Cong Wang, kes haldab liiklust\u00f5rgete juhtimise (TC, Traffic Control) alams\u00fcsteemi tuumas. Kiire taask\u00e4ivitamise meetod p\u00f5hineb varu tuuma eelneval laadimisel m\u00e4lu, mida kasutatakse peamise t\u00f6\u00f6keskkonna tuuma asendamiseks t\u00f5rgete korral v\u00f5i uue versiooni tuuma vahetamiseks. <\/p>\n

Pakkuda l\u00e4henemine v\u00f5imaldab v\u00e4ltida t\u00e4ielikku taask\u00e4ivitamist ja peaaegu koheselt j\u00e4tkata t\u00f6\u00f6d, minimeerides seisaku aega. Praegu, kui tuuma t\u00f6\u00f6s tekib t\u00f5rge, v\u00f5tab t\u00e4ielik taask\u00e4ivitamine suurtel s\u00fcsteemidel mitu minutit. serverid<\/a> v\u00f5tab mitu minutit, kuna seadme algatamisprotsessid, s\u00fcsteemikeskkonna laadimine ja tuuma m\u00e4ludump'i salvestamine kdump'iga v\u00f5ivad olla pikad. P\u00f5him\u00f5tteliselt toimub kdump'i kasutamisel tuuma kahe kordne taask\u00e4ivitamine \u2013 esmalt laaditakse kexec'i kaudu eraldi tuuma eksemplar m\u00e4ludump'i salvestamiseks, seej\u00e4rel laaditakse t\u00f6\u00f6tuuma ja k\u00e4ivitatakse s\u00fcsteemiteenused.<\/p>\n

Kui kmorphi kasutatakse spetsiifilise CPU tuuma kontekstis, laaditakse m\u00e4llu eelnevalt varu Linuxi tuum ja minimaalne s\u00fcsteemikeskkond, mis j\u00e4lgib peatu tuuma seisundit. Kui peatu tuum hangub v\u00f5i satub panic olekusse, v\u00f5tab varu keskkond juhtimise enda k\u00e4tte, salvestab t\u00f5rke tuuma m\u00e4lu kuva, vahetab protsessorituumad, m\u00e4lu, seadmed, v\u00f5rgu konfigureerimise ja failis\u00fcsteemi enda kasuks. <\/p>\n

\u00dclemineku korraldab kaks programmi: kmorph \u2013 t\u00f6\u00f6tab aktiivses keskkonnas, koostab varukeskkonna sisu ja s\u00fcnkroniseerib seal v\u00f5rguseisundi; kmorphd \u2013 t\u00f6\u00f6tab varukeskkonnas ja j\u00e4lgib aktiivse keskkonna seisundit. Lisaks \u00fcleminekule t\u00f5rke korral v\u00f5imaldab kmorphi kasutamine tuuma uuendamist ilma traditsioonilise taask\u00e4ivitamiseta. Varukeskkonna taastamise kiirus on suurenenud, kuna lisaks tuumale ja minimaalsetele s\u00fcsteemikomponentidele v\u00f5ivad ootere\u017eiimis t\u00f6\u00f6tada sellised teenused nagu nginx. Sel juhul on varukeskkonna aktiveerimise hetkeks nginx teenus juba m\u00e4lu laaditud ja hakkab kohe p\u00e4rast \u00fcleminekut t\u00f6\u00f6tama, kui vahetatakse v\u00f5rguadapteri uus keskkond, aktiveeritakse v\u00f5rgu konfiguratsioon ja vahetatakse juur-FS.<\/p>\n

Tehtud testide kohaselt taastab nginx-server kmorph'i abil t\u00f6\u00f6 umbes kahe sekundi p\u00e4rast kerneli nurjumist, kuid tulevikus p\u00fc\u00fctakse saavutada kohest \u00fcleminekut m\u00e4rkamatult \u00fchendatud klientidele. Praegu toetab kmorph arhitektuure x86_64 ja ARM64 ning t\u00f6\u00f6tatakse ka RISC-V toe nimel. Kmorph'i integreerimine Linuxi jaotustesse toimub sarnaselt kdump'i toetusega, kasutades standardseid t\u00f6\u00f6riistu, nagu dracut, initramfs-tools, kernel-install ja systemd teenus.<\/p>\n

Kerneli koosseisu kuuluvad juba Kexec HandOver (KHO) ja Live Update Orchestrator (LUO) mehhanismid, mis v\u00f5imaldavad k\u00e4ivitada uut kerneli vanast ilma s\u00fcsteemi oleku kadumiseta ja seadmete t\u00f6\u00f6 katkestamiseta. Kuid neid ei saa rakendada kerneli nurjumise korral, kuna need vajavad t\u00f6\u00f6tava kerneli oleku salvestamiseks. KHO ja LUO j\u00e4\u00e4vad ka kmorph'i \u00fcleminekukiirusest maha, kuna kmorph'is on uus kerneli juba m\u00e4lus, samas kui KHO ja LUO n\u00f5uavad kerneli taaskehtestamist kexec'i kaudu.
