Crate ax_task 

ArceOS task management module.

This module provides primitives for task management, including task creation, scheduling, sleeping, termination, etc. The scheduler algorithm is configurable by cargo features.

Cargo Features

• multitask: Enable multi-task support. If it’s enabled, complex task management and scheduling is used, as well as more task-related APIs. Otherwise, only a few APIs with naive implementation is available.
• irq: Interrupts are enabled. If this feature is enabled, timer-based APIs can be used, such as sleep, sleep_until, and [WaitQueue::wait_timeout].
• preempt: Enable preemptive scheduling.
• FIFO cooperative scheduler is the default when no scheduler feature is selected.
• sched-rr: Use the Round-robin preemptive scheduler. It also enables the multitask and preempt features if it is enabled.
• sched-cfs: Use the Completely Fair Scheduler. It also enables the the multitask and preempt features if it is enabled.
• host-test: Use host-safe fallbacks for unit tests.

Modules

sync

Native ArceOS synchronization primitives. Native ArceOS synchronization implementation.

Functions

sleep

For single-task situation, we just busy wait for the given duration.

sleep_until

For single-task situation, we just busy wait until reaching the given monotonic deadline.

yield_now

For single-task situation, we just relax the CPU and wait for incoming interrupts.
