Struct perf_event_data::DataSource

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

Describes where in the memory hierarchy the sampled instruction came from.

See the manpage for a full description.

Implementations

impl DataSource

pub fn mem_op(&self) -> MemOp

Type of opcode.

pub fn mem_lvl(&self) -> MemLevel

Memory hierarchy level hit or miss.

pub fn mem_snoop(&self) -> MemSnoop

Snoop mode.

This is a combination of the flags from both the mem_snoop and the mem_snoopx fields in the kernel source.

pub fn mem_lock(&self) -> MemLock

Lock instruction.

pub fn mem_dtlb(&self) -> MemDtlb

TLB access hit or miss.

pub fn mem_lvl_num(&self) -> MemLevelNum

Memory hierarchy level number.

This field is not documented in the manpage but is present within the kernel headers.

pub fn mem_remote(&self) -> bool

Whether the memory access was remote.

This field is not documented in the manpage but is present within the kernel headers.

pub fn mem_blk(&self) -> MemBlk

Access was blocked.

This field is not documented in the manpage but is present within the kernel headers.

pub fn mem_hops(&self) -> u8

The number of hops that were required to perform this memory access.

This field is not document in the man page but is present within the kernel headers.
