Crate axstd

The ArceOS Standard Library

The ArceOS Standard Library is a mini-std library, with an interface similar to rust std, but calling the functions directly in ArceOS modules, instead of using libc and system calls.

These features are exactly the same as those in axfeat, they are used to provide users with the selection of features in axfeat, without import axfeat additionally:

Cargo Features

• CPU
  • smp: Enable SMP (symmetric multiprocessing) support.
  • fp_simd: Enable floating point and SIMD support.
• Interrupts:
  • irq: Enable interrupt handling support.
• Memory
  • alloc: Enable dynamic memory allocation.
  • alloc-tlsf: Use the TLSF allocator.
  • alloc-slab: Use the slab allocator.
  • alloc-buddy: Use the buddy system allocator.
  • paging: Enable page table manipulation.
  • tls: Enable thread-local storage.
• Task management
  • multitask: Enable multi-threading support.
  • sched_fifo: Use the FIFO cooperative scheduler.
  • sched_rr: Use the Round-robin preemptive scheduler.
  • sched_cfs: Use the Completely Fair Scheduler (CFS) preemptive scheduler.
