A few things related to TLB flushing and TLB miss rates
I would like to discuss at LSF/MM:
1) A quick update on IPI-less TLB flushing with
AMD INVLPGB and Intel RAR, and implications
for MM synchronization. Probably no real
discussion needed.
2) A discussion on how we might be able to
integrate mTHPs into khugepaged, and get
TLB miss benefits on AMD and ARM CPUs for
processes where full-size THPs cause too
much memory waste due to internal fragmentation.
Are there any other related topics we should try to
fit into the same time slot?
