pub struct KPageFlags { /* private fields */ }

Parse physical memory flags accessing /proc/kpageflags.

Require root or CAP_SYS_ADMIN

Implementations

impl KPageFlags

pub fn new() -> ProcResult<Self>

Get a parser from default /proc/kpageflags

Return Err if process is not running as root or don’t have CAP_SYS_ADMIN

pub fn from_custom_root<P: AsRef<Path>>(root: P) -> ProcResult<Self>

Get a parser from custom /proc

Return Err if process is not running as root or don’t have CAP_SYS_ADMIN

pub fn get_info(&mut self, pfn: Pfn) -> ProcResult<PhysicalPageFlags>

Retrieve information in the page table entry for the PFN (page frame number) at index page_index. If you need to retrieve multiple PFNs, opt for Self::get_range_info() instead.

Return Err if the PFN is not in RAM (see crate::iomem()): Io(Error { kind: UnexpectedEof, message: “failed to fill whole buffer” }, None)

pub fn get_range_info( &mut self, start: Pfn, end: Pfn ) -> ProcResult<Vec<PhysicalPageFlags>>

Retrieve information in the page table entry for the PFNs within range start (included) and end (excluded) PFNs.

Return Err if any PFN is not in RAM (see crate::iomem()): Io(Error { kind: UnexpectedEof, message: “failed to fill whole buffer” }, None)
