A tick is a notion of time defined by the xv6 kernel, namely the time between two interrupts from the timer chip. Your solution should be in the file user/sleep.c.

The numbers to the left of the file names in the table are sheet numbers. If you want to see the list of running processes at any time, you can type `Control-p` at the xv6 console and it will print out a list of running processes. You may also want to modify this function (`procdump`in `proc.c`) to print out the number of tickets each process has so that you can debug your `settickets` call.Contribute to luoszu/xv6-exp development by creating an account on GitHub.xv6-chinese - 中文版的 MIT xv6 文档 twitter-analysis - The original dataset for my 2013 article on Twitter's network patterns docker-cheat-sheet - Docker Cheat SheetYou have to modify the xv6 kernel to print out a line when each system call is about to return, if the system call's number is set in the mask. The line should contain the process id, the name of the system call and the return value; you don't need to print the system call arguments.阅读procdump和相关代码就可以知道,XV6的进程结构体保存在proc[NPROC]数组当中。而proc->state字段保存了PCB的当前状态,有UNUSED、SLEEPING、RUNNABLE、RUNNING、ZOMBIE五种状态。因此只需要遍历这个数组,然后统计state不是UNUSED状态的就行了。xv6-lottery-scheduling.
