Hi all:<div><br></div><div>I have a couple of questions as described as followings:</div><div><br></div><div>1. struct bheap is binary heap and struct bheap_node represents each heap node in a heap, right ? A traditionally binary heap node could have up to two children, left one and right one. In struct bheap_node, I see its has next and child. Which is the corresponding left child and right child ? Or, child and sibling representation is used, so that a bheap_node only maintain its left child and its sibling. And degree represents how many children it has or what ? In struct bheap, there are head and min. If it was a minimum heap, head and min should points to the same bheap_node, which is the heap root, after each bheap operation like insertion and deletion. When does they differs ?</div>
<div><br></div><div>2. In rt_domian.h, there is a struct rt_domain_t. What is the difference between release_queue and tobe_released. From the comments, they are all related to release queue. But i am a little bit confused about them. Inside requeue function in sched_gsn_edf.c, a task is linked in tobe_released instead of release_queue through calling add_release(&gsnedf,task), if it has not been released . If an example could be shown, it is pretty much clear for me. For example, we have a task set with two tasks, T1(c1,p1) = (3,5) and T2(c2,p2)=(2,6). This task set will be scheduled on one processor by EDF. At time 0, both of their jobs are released. And the release_queue.slot[5] , release_queue.slot[10], ..., release_queue.slot[ min( 5*i, RELEASE_QUEUE_SLOTS) ], maintain jobs from T1, which will be released within window-sized RELEASE_QUEUE_SLOTS. is that right ? </div>
