Description

Describe problem solved by the proposed feature

需求

  • thread stack 支持架构定义阈值，避免中断上下文直接导致栈溢出.
  • thread stack 动态分配方式支持配置。可以（在 smart 上）通过 page 管理器（或其他专用池？）分配。因为 memheap 使用一段时间后产生碎片化，可能分配不出 KB 级别数据.

Contributor guide

Research direction
Investigate RT Thread's thread stack allocation and memory management. Study the current thread stack implementation, including how stack sizes are defined and how memory is allocated (e.g., memheap, page manager). Identify potential improvements such as architecture specific stack thresholds and dynamic allocation using a dedicated pool to avoid memheap fragmentation. Propose a design that ensures stack safety and efficient memory usage.
