Struct uefi::proto::security::MemoryProtection

pub struct MemoryProtection(/* private fields */);

Protocol for getting and setting memory protection attributes.

Corresponds to the C type EFI_MEMORY_ATTRIBUTE_PROTOCOL.

Implementations

impl MemoryProtection

pub fn get_memory_attributes( &self, byte_region: Range<PhysicalAddress> ) -> Result<MemoryAttribute>

Get the attributes of a memory region.

The attribute mask this returns will only contain bits in the set of READ_PROTECT, EXECUTE_PROTECT, and READ_ONLY.

If the attributes are not consistent within the region, Status::NO_MAPPING is returned.

Implementations typically require that the start and end of the memory region are aligned to the UEFI page size.

pub fn set_memory_attributes( &self, byte_region: Range<PhysicalAddress>, attributes: MemoryAttribute ) -> Result

Set the attributes of a memory region.

The valid attributes to set are READ_PROTECT, EXECUTE_PROTECT, and READ_ONLY.

Implementations typically require that the start and end of the memory region are aligned to the UEFI page size.

pub fn clear_memory_attributes( &self, byte_region: Range<PhysicalAddress>, attributes: MemoryAttribute ) -> Result

Clear the attributes of a memory region.

The valid attributes to clear are READ_PROTECT, EXECUTE_PROTECT, and READ_ONLY.

Implementations typically require that the start and end of the memory region are aligned to the UEFI page size.
