<p>Hi all,</p>
<p><br>
</p>
<p>I have a question about he EDF in the base_mt_task.c</p>
<p><br>
</p>
<p>void* rt_thread(void *tcontext)</p>
<p>{</p>
<p><span class="Apple-tab-span" style="white-space:pre"></span>int do_exit;</p>
<p><span class="Apple-tab-span" style="white-space:pre"></span>struct thread_context *ctx = (struct thread_context *) tcontext;</p>
<p><span class="Apple-tab-span" style="white-space:pre"></span>struct rt_task param;</p>
<p><br>
</p>
<p><span class="Apple-tab-span" style="white-space:pre"></span>/* Set up task parameters */</p>
<p><span class="Apple-tab-span" style="white-space:pre"></span>init_rt_task_param(¶m);</p>
<p><span class="Apple-tab-span" style="white-space:pre"></span>param.exec_cost = ms2ns(EXEC_COST);</p>
<p><span class="Apple-tab-span" style="white-space:pre"></span>param.period = ms2ns(PERIOD);</p>
<p><span class="Apple-tab-span" style="white-space:pre"></span>param.relative_deadline = ms2ns(RELATIVE_DEADLINE);</p>
<p> ......</p>
<p> ......</p>
<p><br>
</p>
<p>}</p>
<p><br>
</p>
<p>My computer have four cores and I created 5 thread with different deadlines, when I measure the time that when the thread finished, actually the thread which has the latest deadline are not finished last most of the time. I don't quite understand why it
happened like this, does any one have any ideas? Or any suggestions that how I can use it? Thank you very much. </p>
