scxcash: Cache Usage Analyzer for sched_ext Schedulers

Fields

pid: Option<u32>

PID of the process to monitor for cache usage events.

verbose: u8

Enable verbose output, including libbpf details. Specify multiple times to increase verbosity.

soft_dirty: bool

Enable the soft-dirty cache monitor. If no monitor selection flags are provided, this monitor is enabled by default.

perf_sample: bool

Enable perf sampling monitor (prototype: samples HW cycles for now).

perf_freq: u64

Perf sampling frequency (samples per second).

json: bool

Output consumed monitor values as JSON (one per line). When not set, values are printed using Debug formatting.

interval: u64

Interval in seconds between poll/consume cycles. Defaults to 1s.

ring_mb: u32

Ring buffer size in megabytes (default is 4 MB).

hints: bool

Monitor task-local storage updates for a hint map.

hints_map: Option<String>

Pin path of the task hint TLS map (mandatory with –hints).

Trait Implementations

impl Args for Opts

fn group_id() -> Option<Id>

Report the [ArgGroup::id][crate::ArgGroup::id] for this set of arguments

fn augment_args<'b>(__clap_app: Command) -> Command

Append to [Command] so it can instantiate Self via [FromArgMatches::from_arg_matches_mut]

fn augment_args_for_update<'b>(__clap_app: Command) -> Command

Append to [Command] so it can instantiate self via [FromArgMatches::update_from_arg_matches_mut]

impl CommandFactory for Opts

fn command<'b>() -> Command

Build a [Command] that can instantiate Self.

fn command_for_update<'b>() -> Command

Build a [Command] that can update self.

impl Debug for Opts

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl FromArgMatches for Opts

fn from_arg_matches(__clap_arg_matches: &ArgMatches) -> Result<Self, Error>

Instantiate Self from [ArgMatches], parsing the arguments as needed.

fn from_arg_matches_mut( __clap_arg_matches: &mut ArgMatches, ) -> Result<Self, Error>

Instantiate Self from [ArgMatches], parsing the arguments as needed.

fn update_from_arg_matches( &mut self, __clap_arg_matches: &ArgMatches, ) -> Result<(), Error>

Assign values from ArgMatches to self.

fn update_from_arg_matches_mut( &mut self, __clap_arg_matches: &mut ArgMatches, ) -> Result<(), Error>
