Structs

DeferredPageTableFrames

Intermediate page-table frames detached by one leaf removal.

DetachedPageTableFrame

A page-table frame detached from a live page-table tree.

Frame

页表帧，代表一个物理页面上的页表

HugeSplitApplyError

Failed structural apply that returns the still-unpublished deposit to its caller. Transactional users must not lose the only child-table owner merely because the observed huge leaf became stale before apply.

HugeSplitDeposit

A child-table deposit bound to one observed huge leaf.

InstalledHugeSplit

Receipt proving that one deposited child table is now reachable from the page-table tree.

MapConfig

页表映射配置

MapRecursiveConfig

内部映射递归配置

MemoryDescriptor

PageTable

PageTableInfo

PageTableLeafPlan

Immutable identity of one occupied leaf.

PageTableMapApplyError

Failed structural apply that returns the still-unpublished map deposit.

PageTableMapDeposit

Move-only ownership of a detached page-table suffix for one exact leaf.

PageTableMapPlan

Allocation-free description of where one absent leaf may be installed.

PageTableMovePlan

Allocation-free preimage for one page-table leaf relocation.

PageTablePathApplyError

Failed path publication that returns every still-detached table frame.

PageTablePathDeposit

Move-only ownership of page-table directories prepared for one vacant leaf.

PageTableRef

PageTableWalker

页表遍历迭代器

PhysAddr

A physical memory address.

PteInfo
