Bharata and I would like to propose the following topic for LSFMM.
Topic: Overhauling hot page detection and promotion based on PTE A bit scanning.
Thank you for proposing this. I'm interested in this!
Thank you.
[...]
virtual vs physical address based scanning,
DAMON supports both virtual and physical address spaces monitoring. DAMON's
pages migration is currently not supported for virtual address spaces, though I
believe adding the support is not difficult.
Will check this.

3. Discuss how hardware provided hotness info (like AMD IBS) can further aid
promotion. Bharata had posted an RFC [4] on this a while back.
Maybe CXL Hotness Monitoring Unit could also be an interesting thing to discuss
together.
Definitely.
4. Overlap with DAMON and potential reuse.
I confess that it seems some of the works might overlap with DAMON to my biased
eyes. I'm looking forward to attend this session, to make it less biased and
more aligned with people :)
Yes. Agree.
