Linuxi tuumiku postituslistis on esitatud kuues versioon Kexec HandOver (KHO) mehhanismi plaastritest, mida arendavad insenerid Amazonist, Microsoftist ja Google'ist. Plaastrid on juba vastu v\u00f5etud mm-everything harusse, kuhu kogutakse muudatusi tulevase 6.16 tuuma haru jaoks, mis on seotud m\u00e4lu haldamisega. Kexec HandOver alusel arendab Google Live Update Orchestratori (LUO) alams\u00fcsteemi, mis v\u00f5imaldab tuuma taask\u00e4ivitamist ilma seadmete t\u00f6\u00f6 katkestamiseta. <\/p>\n

Kexec HandOver v\u00f5imaldab k\u00e4ivitada uut kernelit vanast ilma s\u00fcsteemi olekut kaotamata. Praegu t\u00f6\u00f6tab kexec() kutse lihtsalt laadijana, k\u00e4ivitades uue kerneliga, mis seej\u00e4rel t\u00e4ielikult s\u00fcsteemi uuesti initsialiseerib, mis on ekvivalentne taask\u00e4ivitamisega, kuid ilma p\u00fcsivara osaluseta. Ettepaneku seeria plaaste rakendab teistsuguse l\u00e4henemise. Enne uue kerneliversiooni juhtimisele andmist serialiseeritakse v\u00f5tmes\u00fcsteemide olek m\u00e4llu, mis ei j\u00e4\u00e4 j\u00e4rgmiste operatsioonide alla. Uus kernel, omades juhtimist, taastab serialiseeritud oleku tagasi. \u00dclej\u00e4\u00e4nud programmide seisukohalt on kernelivahetuse operatsioon n\u00e4htamatu. <\/p>\n

Kexec HandOver v\u00f5ib olla kasulik olukordades, kus seiskamine ei ole lubatud ja on vajalik tagada \u00fcksikute seadmete pidev t\u00f6\u00f6ts\u00fckkel. N\u00e4iteks virtualiseerimiserveritel v\u00f5ib Kexec HandOver't kasutada kernelikuuenduseks (ja h\u00fcperviisori), mitte puudutades virtuaalmasinatele eraldatud m\u00e4lu ja s\u00e4ilitades nende t\u00f6\u00f6 oleku.
