Umdidiyeli odumile weLinux Kernel noMqondisi uGreg Kroah-Hartman umemezele ukuphela komjikelezo wempilo wochungechunge lweLinux Kernel 4.20, ikhuthaza abasebenzisi ukuthi bathuthukele ku-kernel entsha ngokushesha okukhulu.
Kukhishwe ngoDisemba 23, 2018, uchungechunge lweLinux Kernel 4.20 lulethe nethoni yokuthuthuka, kufaka phakathi ukulungiswa kwe-Indirect Branch Prediction Barrier (IBPB) kusetshenziswa ukulawula umsebenzi, kanye nokunciphisa ukuhlaselwa okuhlobene nokuba sengozini kweSpecter.
Ngokwengeziwe, yethule ukuvikelwa okungcono ekuncipheni kwe-Specter variant 2, ukuvikelwa okungcono kwe-Specter variant 4 kuma-processor we-ARM64 (AArch64), ukusekelwa kwamakhadi emidwebo we-AMD Radeon Pro Vega, ukusekelwa kokwakhiwa kweprosesa le-C-SKY, kanye nokuxhaswa kweHygon Dhyana Amaprosesa we-x86 ne-AMD Radeon Picasso namakhadi wehluzo weRaven 2.
Kepha njengoba zonke izinto ezinhle kufanele ziphele, I-Linux Kernel 4.20 ifinyelela ukuphela kwempilo yayo ngalesi sibuyekezo sakamuva, iLinux Kernel 4.20.17, okusho ukuthi ngeke zisaba khona izibuyekezo zalolu chungechunge. Manje ukusatshalaliswa okukhethiwe yiLinux Kernel 5.0.
Thuthukela ku-Linux Kernel 5.0 manje
Uma usebenzisa i-kernel yochungechunge lwe-Linux 4.20 ekusatshalalisweni kwakho, njengamanje kunezinketho ezimbili, thuthukela enguqulweni yakamuva, iLinux Kernel 4.20.17 noma thuthukela kuLinux Kernel 5.0. Uma i-Linux Kernel 5.0 ingatholakali ezinqolobaneni zakho zokusabalalisa, kungcono ukuthuthukela kunkozo yesikhathi eside (LTS) ehambisanayo.
Uchungechunge lweLinux Kernel ngokuxhaswa kweLTS kufaka phakathi iLinux 4.19 (kunconyiwe), iLinux 4.14, iLinux 4.9, iLinux 4.4, neLinux 3.16. Kepha Sincoma ukuthuthukela ku-Linux Kernel 5.0 ngokushesha okukhulu.
