问题 In Minix 3.1.2a I've a struct " struct proc " where the PCB of any process stored, but I've a problem when adding new attribute " p_currenthash " in the code below to this struct. I can't change its value except using a constant defined by #define directive; otherwise, the system stops responding. For clarity here is the structure: struct proc { struct stackframe_s p_reg; /* process' registers saved in stack frame */ #if (CHIP == INTEL) reg_t p_ldt_sel; /* selector in gdt with ldt base and

MINIX Internal Fragmentation 2

阅读更多关于 MINIX Internal Fragmentation 2

问题 I am in the middle of writing some software in C that recursively lists all files in a given directory and now I need to work out the internal fragmentation. I have spent a long time researching this and have found out that the internal fragmentation on ext2 only occurs in the last block. I know that from an inode number in theory you should be able to get the first and last block addresses but I have no idea how. I have looked into stat() , fcntl() and all sorts of ways. How do I get the

阅读更多关于 Minix vs Linux for Learning Operating System Design?

问题 I wish to learn operating system design. I was wondering if I should tackle Minix or GNU/Linux in the process? I like books so I would be following mainly a book, though video resources (presumably videotaped lectures) would also be welcome. I have formally studied C and C# and can program small to medium sized programs in them. I also have a very basic understanding of data structures. If I take the Minix route, should I tackle version 2 (simpler??) or version 3? 回答1: I would go for the

Number of Running Processes on a Minix system from C code

阅读更多关于 Number of Running Processes on a Minix system from C code

So, this seemed simple at first, but after crawling Google and here, the answer doesn't seem as simple as I first thought. Basically, I'm editing a MINIX kernel as part of a practical for my Operating Systems course, and I have to add a little function that spits out the number of running processes when you hit a function key in the Information Server. I've figured out how to integrate the functionality so all the other stuff works, but for the life of me, I can not figure out how to get the current number of processes running in the system into my C code and into a variable to print out.
