  • Method for extending memory isolation domain, and electronic device
    Patent number: 12705188
    Abstract: A method for extending a memory isolation domain includes allocating memories of multiple isolation domains, where the multiple isolation domains are in a correspondence with N protection keys and M extended page tables. When a first application is allowed to access a memory of a first isolation domain, the method further includes determining, based on the correspondence, a first protection key and a first extended page table that correspond to the first isolation domain, where the multiple isolation domains include the first isolation domain, the N protection keys include the first protection key, and the M extended page tables include the first extended page table. The method further includes enabling access permission for the first isolation domain based on the first protection key and the first extended page table, for the first application to access the memory of the first isolation domain.
