[PATCH RFC kernel] balloon: speed up inflating/deflating process
The implementation of the current virtio-balloon is not very efficient, Bellow is test result of time spends on inflating the balloon to 3GB of a 4GB idle guest: a. allocating pages (6.5%, 103ms) b. sending PFNs to host (68.3%, 787ms) c. address translation (6.1%, 96ms) d. madvise (19%, 300ms) It takes about 1577ms for the whole inflating process to complete. The test shows that the bottle neck is the stage b and stage d. If using a bitmap to send the page info instead of the PFNs, we can reduce the overhead spends on stage b...
