工作队列使用struct k_work_q类型去定义,工作队列需要使用自己定义的栈,然后调用k_work_q_start()去初始化: AI检测代码解析 #define MY_STACK_SIZE 512 #define MY_PRIORITY 5 K_THREAD_STACK_DEFINE(my_stack_area, MY_STACK_SIZE); struct k_work_q my_work_q; k_work_q_start(&my_work_q, my_s...

调用函数k_work_submit()可以将已初始化的工作项提交到系统工作队列中;调用函数k_work_submit_to_queue()可以将已初始化的工作项提交到指定的工作队列中。提交一个延迟的工作项使用类型为struct k_delayed_work的变量可以定义一个延迟工作项。延迟工作项必须使用函数 k_delayed_work_init()初始化。调用函数k_...

Typically APIs that have callbacks allow for a user_data parameter (usually void*) to be passed to the callback function to provide contextual information. Proposed solution is to append a user_data field to struct k_work I considered wr...

Describe the bug I'm not entirely sure here, but it appears that when calling on k_work_submit_to_queue() from an ISR it doesn't reschedule to do that work when running on a single core. It will just go to idle as if there is nothing to ...
