riscv-stack

Methods for RISCV processors to determine stack size and how much of the stack has been or is being used.

This is a fork of cortex-m-stack but ported to RISCV.

Warning: this crate depends on the _stack_start and _hart_stack_size symbols being set correctly. Correctly means _hart_stack_size is equal among all harts therefore the beginning of each hart's stack can be found at _stack_start - (_hart_stack_size * hart_id) (with adjustments for alignment). The linker script provided by riscv-rt should satisfy these requirements.

Immediate stack usage

Use [current_stack_in_use] or [current_stack_free] to keep track of the memory usage at run-time.

Historical stack usage

First paint the stack using [repaint_stack] and then measure using [stack_painted] or [stack_painted_binary] to figure out how much stack was used between these two points.
