Kernel je dostupan za arhitekture x86_64 i ARM64 (aarch64). Izvorni kodovi kernela, uklju\u010duju\u0107i razdvajanje na odvojene zakrpe, objavljeni su u javnom Git repozitoriju Oracle-a.    <\/p>\n<p>Paket Unbreakable Enterprise Kernel 6 temelji se na Linux kernelu 5.4 (UEK R5 se temeljio na kernelu 4.14), koji je oboga\u0107en novim mogu\u0107nostima, optimizacijama i ispravcima, te je testiran na kompatibilnost s ve\u0107inom aplikacija koje rade u RHEL-u, a posebno optimiziran za rad s industrijskim softverom i opremom Oracle-a.
