La s\u00e9rie de correctifs de la sixi\u00e8me version de Kexec HandOver (KHO), d\u00e9velopp\u00e9e par des ing\u00e9nieurs des entreprises Amazon, Microsoft et Google, est pr\u00e9sent\u00e9e dans la liste de diffusion du noyau Linux. Les correctifs ont d\u00e9j\u00e0 \u00e9t\u00e9 int\u00e9gr\u00e9s dans la branche mm-everything, o\u00f9 les modifications pour la future branche 6.16 du noyau, li\u00e9es \u00e0 la gestion de la m\u00e9moire, sont accumul\u00e9es. Sur la base de Kexec HandOver, Google d\u00e9veloppe le sous-syst\u00e8me Live Update Orchestrator (LUO), qui permet de red\u00e9marrer le noyau sans arr\u00eater le fonctionnement des appareils. <\/p>\n

Kexec HandOver permet de lancer un nouveau noyau \u00e0 partir de l'ancien sans perte d'\u00e9tat du syst\u00e8me. Actuellement, l'appel \u00e0 kexec() fonctionne uniquement comme un chargeur, lan\u00e7ant simplement un nouveau noyau qui r\u00e9initialise compl\u00e8tement le syst\u00e8me par la suite, ce qui \u00e9quivaut \u00e0 un red\u00e9marrage, mais sans l'intervention du firmware. La s\u00e9rie de correctifs propos\u00e9e met en \u0153uvre une approche diff\u00e9rente. Avant de transf\u00e9rer le contr\u00f4le \u00e0 la nouvelle version du noyau, l'\u00e9tat des sous-syst\u00e8mes cl\u00e9s du noyau est s\u00e9rialis\u00e9 dans une zone m\u00e9moire qui ne sera pas affect\u00e9e par les op\u00e9rations ult\u00e9rieures. Le nouveau noyau, une fois en contr\u00f4le, restaure l'\u00e9tat s\u00e9rialis\u00e9. Du point de vue des autres programmes, l'op\u00e9ration de remplacement du noyau est ind\u00e9tectable. <\/p>\n

Kexec HandOver peut s'av\u00e9rer utile dans des situations o\u00f9 l'arr\u00eat n'est pas acceptable et o\u00f9 il est n\u00e9cessaire d'assurer un cycle de fonctionnement continu de certains appareils. Par exemple, sur des serveurs de virtualisation, Kexec HandOver peut \u00eatre utilis\u00e9 pour mettre \u00e0 jour le noyau (et l'hyperviseur KVM<\/a>), sans affecter la m\u00e9moire occup\u00e9e par les machines virtuelles, et en pr\u00e9servant l'\u00e9tat de leur ex\u00e9cution.
