CONFIG_X86_COMMON_PAGE_TABLE
¶
Use a single page table for all threads
Type: bool
Help¶
If this option is enabled, userspace memory domains will not have their own page tables. Instead, context switching operations will modify page tables in place. This is much slower, but uses much less RAM for page tables.
Direct dependencies¶

&& !X86_KPTI
