Struct EcamAccess

Source 
pub struct EcamAccess {
    base: *mut u8,
}
Expand description

ECAM (PCIe Enhanced Configuration Access Mechanism) implementation.

Fields§

§base: *mut u8

Base address of ECAM region.

Implementations§

Source§

impl EcamAccess

Source

pub unsafe fn new(base: *mut u8) -> Self

Create a new ECAM accessor.

§Safety
  • base must be a valid pointer to the ECAM memory region.
  • The region must be at least 256MB (for full bus range).
Source

pub fn base(&self) -> *mut u8

Get the base address.
