READ Process Management PDF Processes begins from P0, which kfork a P1, switch to run P1, which may kfork other procs. The processes form a family tree, which looks like this: P0 | P1 (never let P1 exit) | ------------------------ P2 P3 P4 | -------- P5 P6 BASE CODE: samples/MID2/mid2.tgz. It supports switch: tswitch() to switch process Kfork : kfork(body,1) to kfork a child process (1). ADD a ps command, which prints the status of all PROCS (2). Modify kfork() to implement process family tree as a BINARY tree by using the child, sibling, parent pointers. (3). Implement ksleep()/kwakeup() as in Chapter 5.6.1 Implement a sleepList for all SLEEP process ADD sleep, wakeup commands and show they work. When a process runs, show its pid, ppid and child list. For clarity, also show freeList, readyQueue and sleepList (4). Implement kexit(int exitCode) as in Section 2 of the PDF file (5). Implement pid = wait(int *status) as in Section 4 of the PDF file For testing: ADD a wait command for ANY process to wait for a ZOMBIE child.
