| osptr_t hal_pc_from_ctxt | ( | osstkptr_t | ctxt_ptr | ) |
Compute the program counter, from the stored context This function is used for debugging.
Implement this by extracting the program counter out of the context (or stack pointer) if possible.
| ctxt_ptr | The pointer to the task context |
| osword_t hal_stkusage_max | ( | osstpktr_t | ctxt_ptr, | |
| osstkptr_t | base_stkptr, | |||
| osword_t | stksize | |||
| ) |
Return the maximum stack occupancy of the task.
This hal implemented function should provide the maximum stack occupancy of the task whose context is given. This is used for debugging. It is valid for this function to return 0, if this information is not readily extractable.
| ctxt_ptr | Context of the task. | |
| base_stkptr | The initialization stack value for this task that was passed to hal_stk_init | |
| stksize | The initial stack size for this task that was passed to hal_stk_init |
| osword_t hal_stkusage_curr | ( | osstpktr_t | ctxt_ptr, | |
| osstkptr_t | base_stkptr, | |||
| osword_t | stksize | |||
| ) |
Return the current stack occupancy of the task.
This hal implemented function should provide the current stack occupancy of the task whose context is given. This is used for debugging. It is valid for this function to return 0, if this information is not readily extractable.
| ctxt_ptr | Context of the task. | |
| base_stkptr | The initialization stack value for this task that was passed to hal_stk_init | |
| stksize | The initial stack size for this task that was passed to hal_stk_init |
