Google'i insenerid on avaldanud arutamiseks Linuxi tuumaarendajatele komplekti pat\u0161e, mis sisaldab Live Update Orchestrator (LUO) alams\u00fcsteemi rakendust, mis on m\u00f5eldud tuuma v\u00e4rskendamiseks Live-re\u017eiimis. Erinevalt sellistest mehhanismidest nagu livepatch, Ksplice, kpatch ja kGraft ei piirdu uus s\u00fcsteem \u00fcksikute paranduste rakendamise v\u00f5imaluselt t\u00f6\u00f6tavale Linuxi tuumale, vaid v\u00f5imaldab t\u00e4ielikku taask\u00e4ivitamist ja tuuma v\u00e4rskendamist ilma erinevate seadmete t\u00f6\u00f6 katkestamata. Projekt p\u00f5hineb Kexec HandOver (KHO) komplektidel pat\u0161ides, mis on m\u00f5eldud kexec mehhanismi jaoks, mis v\u00f5imaldab laadida uut tuuma juba t\u00f6\u00f6tavast Linuxi tuumast ilma f\u00fc\u00fcsilise taask\u00e4ivitamiseta. <\/p>\n

LUO peamine rakendusvaldkond on pilvekeskkonnad, kus on v\u00f5imalik KVM h\u00fcperviisori v\u00e4rskendamine katkematult t\u00f6\u00f6tavate virtuaalmasinate jaoks. virtuaalmasinad<\/a>Eriti on v\u00f5imalik peatada virtuaalmasinatele<\/a> tuuma taask\u00e4ivitamise ajaks h\u00fcperviisoriga, hoides k\u00f5ik virtuaalmasinatega \u00fchendatud seadmed t\u00f6\u00f6korras. <\/p>\n

Selle v\u00f5imaluse elluviimiseks pakub LUO lahendusi seadmete oleku salvestamiseks enne \u00fcleminekut uuele tuumale ja oleku taastamiseks kohe p\u00e4rast uue tuuma kasutusele v\u00f5tmist, nii et s\u00fcsteemi ja rakenduste pidevad toimingud kasuturu ruumis seadmetega ei katkestaks. Tuuma taask\u00e4ivitamise k\u00e4igus tagatakse ka DMA tegevuse katkematus ja katkestuste t\u00f6\u00f6tlemise seotud aktiivsus. <\/p>\n

Olemasoleku haldamiseks ja uuele tuumale \u00fcleminekuks annab LUO API, mis v\u00f5imaldab teistel tuuma alams\u00fcsteemidel \u00fchendada t\u00f6\u00f6tlejat, et j\u00e4lgida ja osaleda Live-restartimise protsessis. LUO-ga integreeruda saavad alams\u00fcsteemid h\u00f5lmavad KVM h\u00fcperviisorit, iommu, katkestuss\u00fcsteemi ja draivereid. M\u00e4lu oleku edastamiseks vanalt tuumalt uuele kasutatakse KHO-d (Kexec HandOver). Halduse teostamine toimub sysfs failide kaudu «\/sys\/kernel\/liveupdate\/{state, prepare, finish}».
