Crate libax

ArceOS user program library, with an interface similar to rust std, but calling the functions directly in ArceOS modules, instead of using libc and system calls.

Cargo Features

• CPU
  • smp: Enable SMP (symmetric multiprocessing) support.
  • fp_simd: Enable floating point and SIMD support.
• Memory
  • alloc: Enable dynamic memory allocation.
  • paging: Enable page table manipulation.
• Interrupts:
  • irq: Enable interrupt handling support. This feature is required for some multitask operations, such as sync::WaitQueue::wait_timeout and non-spinning thread::sleep.
• Task management
  • multitask: Enable multi-threading support.
  • sched_fifo: Use the FIFO cooperative scheduler.
  • sched_rr: Use the Round-robin preemptive scheduler.
• Device and upperlayer stack
  • fs: Enable file system support.
  • net: Enable networking support.
  • display: Enable graphics support.
  • bus-mmio: Use device tree to probe all MMIO devices.
  • bus-pci: Use PCI bus to probe all PCI devices.
• Logging
  • log-level-off: Disable all logging.
  • log-level-error, log-level-warn, log-level-info, log-level-debug, log-level-trace: Keep logging only at the specified level or higher.
• Platform
  • platform-pc-x86: Specify for use on the corresponding platform.
  • platform-qemu-virt-riscv: Specify for use on the corresponding platform.
  • platform-qemu-virt-aarch64: Specify for use on the corresponding platform.
• Other
  • cbindings: Generate C bindings, to support C applications.
