En termes de probl\u00e8mes r\u00e9solus, Parker rappelle le projet Multikernel pr\u00e9sent\u00e9 il y a quelques jours, mais se distingue par son architecture et sa mise en \u0153uvre.    <\/p>\n<p>Dans Parker, il y a une section des noyaux CPU, de la m\u00e9moire et des dispositifs existants. Chaque instance de noyau ex\u00e9cut\u00e9e est bas\u00e9e sur une image de noyau commune, mais peut utiliser diff\u00e9rentes configurations et optimisations. Le premier noyau charg\u00e9 (Boot Kernel) s'occupe de la r\u00e9partition et de la section des dispositifs mat\u00e9riels. Les autres instances de noyau Linux (Application Kernel) fonctionnent uniquement avec leurs noyaux CPU, m\u00e9moires et dispositifs d'entr\u00e9e\/sortie qui leur sont associ\u00e9s.     <\/p>\n<p>Dans la version initiale, pour r\u00e9duire les co\u00fbts g\u00e9n\u00e9raux et simplifier la mise en \u0153uvre, il n'y a pas de m\u00e9canisme de gestion et tous les noyaux utilisent une seule zone d'isolation (domain), c'est-\u00e0-dire qu'une erreur dans n'importe quelle instance de noyau peut entra\u00eener des probl\u00e8mes dans l'ensemble du syst\u00e8me. \u00c0 l'avenir, il est pr\u00e9vu d'utiliser des fonctionnalit\u00e9s mat\u00e9rielles distinctes pour isoler les instances de noyau. Parker est mentionn\u00e9 comme \u00e9tant applicable aux ordinateurs avec un grand nombre de noyaux CPU, o\u00f9 des probl\u00e8mes surgissent lors de la mise \u00e0 l'\u00e9chelle des t\u00e2ches.               <\/p>\n<p>Pour la gestion, Parker a mis en \u0153uvre une interface bas\u00e9e sur kernfs, et pour charger des instances suppl\u00e9mentaires de noyau dans des zones de m\u00e9moire r\u00e9serv\u00e9es, kexec est utilis\u00e9. Avant le lancement d'autres noyaux, le noyau principal lib\u00e8re les noyaux CPU, r\u00e9serve la m\u00e9moire physique et d\u00e9tache les dispositifs PCI pour leur utilisation dans le noyau sectionn\u00e9. Chaque noyau doit \u00eatre associ\u00e9 \u00e0 son propre dispositif PCIe, tel qu'un disque NVMe ou un adaptateur r\u00e9seau, pour les entr\u00e9es\/sorties. Une fois qu'une instance de noyau est lanc\u00e9e, elle ne peut pas interagir avec d'autres noyaux.<br \/>\n<br \/>Source : <a content=\"nofollow\" rel=\"nofollow\"
