Data Fields
uint64_t	start
	Scheduler/domain-specific start state (e.g.
const struct sof_uuid_entry *	uid
	UUID identifying the task or associated component.
uint16_t	type
	Scheduler type identifier (SOF_SCHEDULE_*).
int16_t	priority
	Priority of the task (lower values run first).
uint16_t	core
	Execution core ID affinity.
uint16_t	flags
	Custom task flags.
struct schedule_data *	sch
	Pointer to scheduler instance bound to this task.
enum task_state	state
	Current task lifecycle state.
void *	data
	Custom context pointer passed to task operations.
struct list_item	list
	List node linking task into scheduler run queue.
void *	priv_data
	Scheduler-specific private task context.
struct task_ops	ops
	Task operations callbacks table.
struct k_work_delayable	z_delayed_work
	Zephyr delayable work item (used by legacy EDF).
uint32_t	cycles_sum
	Cumulative execution cycles.
uint32_t	cycles_max
	Maximum cycle count recorded in a single run.
uint32_t	cycles_cnt

Detailed Description

Core task structure managed by SOF schedulers.

Field Documentation

core

uint16_t task::core

Execution core ID affinity.

cycles_cnt

uint32_t task::cycles_cnt

Number of completed execution runs.

cycles_max

uint32_t task::cycles_max

Maximum cycle count recorded in a single run.

cycles_sum

uint32_t task::cycles_sum

Cumulative execution cycles.

data

void* task::data

Custom context pointer passed to task operations.

flags

uint16_t task::flags

Custom task flags.

list

struct list_item task::list

List node linking task into scheduler run queue.

ops

struct task_ops task::ops

Task operations callbacks table.

priority

int16_t task::priority

Priority of the task (lower values run first).

priv_data

void* task::priv_data

Scheduler-specific private task context.

sch

struct schedule_data* task::sch

Pointer to scheduler instance bound to this task.

start

uint64_t task::start

Scheduler/domain-specific start state (e.g.

absolute next-run tick timestamp in LL).

state

enum task_state task::state

Current task lifecycle state.

type

uint16_t task::type

Scheduler type identifier (SOF_SCHEDULE_*).

uid

const struct sof_uuid_entry* task::uid

UUID identifying the task or associated component.

z_delayed_work

struct k_work_delayable task::z_delayed_work

Zephyr delayable work item (used by legacy EDF).
