Hi Michal, thanks for your replay and suggestions.
Yes the memory consumption is going to increase but the question is whether this is something that is a real problem. Is it really common to have many vmas with a dedicated policy?
Yes, it does not a realy problem.
What I am arguing here is that there are essentially 2 ways forward. Either we continue to build up on top of the existing and arguably very fragile code and make it even more subtle or follow a general pattern of a proper reference counting (with usual tricks to reduce cache line bouncing and similar issues). I do not really see why memory policies should be any different and require very special treatment.
I got it. It is rather subtle and easy to get wrong if we push forward with the existing way and it is a good opportunity to get from the existing subtle model. I will try that on next version. __ Best Regards, Zhongkun
