Struct probe_rs::architecture::arm::component::TraceMemoryController

pub struct TraceMemoryController<'a> { /* private fields */ }

The embedded trace memory controller.

Implementations

impl<'a> TraceMemoryController<'a>

pub fn new( interface: &'a mut dyn ArmProbeInterface, component: &'a CoresightComponent ) -> Self

Construct a new embedded trace fifo controller.

pub fn set_mode(&mut self, mode: Mode) -> Result<(), Error>

Configure the FIFO operational mode.

Args

• mode - The desired operational mode of the FIFO.

pub fn enable_capture(&mut self) -> Result<(), Error>

Enable trace captures using the FIFO.

pub fn disable_capture(&mut self) -> Result<(), Error>

Disable trace captures using the FIFO.

pub fn read(&mut self) -> Result<Option<u32>, ArmError>

Attempt to read a value out of the FIFO

pub fn full(&mut self) -> Result<bool, Error>

Check if the FIFO is full.

pub fn empty(&mut self) -> Result<bool, Error>

Check if the FIFO is empty.

pub fn ready(&mut self) -> Result<bool, Error>

Check if the ET capture has stopped and all internal pipelines and buffers have been drained.

pub fn triggered(&mut self) -> Result<bool, Error>

Check if the ETF has triggered.

Note

This will only be set when operating in circular buffer modes.

pub fn fill_level(&mut self) -> Result<u32, Error>

Get the current number of bytes within the FIFO.

Note

This will always return zero if the capture is disabled.

pub fn stop_on_flush(&mut self, stop: bool) -> Result<(), Error>

Configure the capture stop-on-flush semantics.

Args

• stop - Specified true if the capture should stop on flush events.

pub fn manual_flush(&mut self) -> Result<(), Error>

Generate a manual flush event.

pub fn fifo_size(&mut self) -> Result<u32, ArmError>

Get the size of the FIFO in bytes.
