What are the VM motivations??

Quoted 9 lines · Russell Leighton

I read this thread as asking the question:

If VM management is viewed as an optimization problem, then what exactly is the function that you are optimizing and what are
the constraints?

If you could express that well with a even a very loose model, then the code could be reviewed to see if it was really doing what was intended and assumptions could be tested.

May I suggested an algorithm?

- Write down what you think the optimization constraints are. (be specific, for example, enumerate all the flavors of page types - process code, process data, page cache file data, page cache swap cache, anonymous, shmem, etc.)

- Write down what you think the current algorithms are. (again, be specific, use file names, function names, pseudocode and snippets of existing code.)

- Send it to Rik. He'll tell you if it's right.
