Na seznamu razdelitve jedra Linuxa je predstavljena \u0161esta razli\u010dica popravkov za implementacijo mehanizma Kexec HandOver (KHO), ki ga razvijajo in\u017eenirji podjetij Amazon, Microsoft in Google. Popravki so \u017ee sprejeti v vezo mm-everything, kjer se zbirajo spremembe za prihodnjo vejo jedra 6.16, povezane z upravljanjem pomnilnika. Na osnovi Kexec HandOver podjetje Google razvija podsistem Live Update Orchestrator (LUO), ki omogo\u010da ponovno nalaganje jedra brez ustavitve delovanja naprav. <\/p>\n

Kexec HandOver omogo\u010da zagon novega jedra iz starega brez izgube stanja sistema. Trenutno klic kexec() deluje le kot nalagalnik, ki preprosto za\u017eene novo jedro, ki nato popolnoma ponovno inicializira sistem, kar je ekvivalentno ponovnemu zagonu, le brez sodelovanja izvajalnika programske opreme. Predlagana serija popravkov izvaja druga\u010den pristop. Pred predajo nadzora novi razli\u010dici jedra se stanje klju\u010dnih podsistemov jedra serializira v pomnilni\u0161ki regiji, ki ne bo prizadeta s prihodnjimi operacijami. Novo jedro, ko prevzame nadzor, obnovi serializirano stanje nazaj. Z vidika ostalih programov je operacija zamenjave jedra neopazna. <\/p>\n

Kexec HandOver bi lahko bil uporaben v situacijah, ko ustavitev ni dovoljena in je potrebno zagotoviti neprekinjen cikel dela posameznih naprav. Na primer, na stre\u017enikih za virtualizacijo se lahko Kexec HandOver uporablja za posodobitev jedra (in hipervizorja), ne da bi prizadela pomnilnik, ki ga zasedajo virtualne naprave, ter ohranjala stanje njihovega izvajanja.
