Crate page_table

This crate provides generic, unified, architecture-independent, and OS-free page table structures for various hardware architectures.

The core struct is PageTable64<M, PTE, IF>. OS-functions and architecture-dependent types are provided by generic parameters:

• M: The architecture-dependent metadata, requires to implement the PagingMetaData trait.
• PTE: The architecture-dependent page table entry, requires to implement the GenericPTE trait.
• IF: OS-functions such as physical memory allocation, requires to implement the PagingIf trait.

Currently supported architectures and page table structures:

• x86: x86_64::X64PageTable
• ARM: aarch64::A64PageTable
• RISC-V: riscv::Sv39PageTable, riscv::Sv48PageTable

Re-exports

• pub use page_table_entry::GenericPTE;
• pub use page_table_entry::MappingFlags;
