Phoronix: Amazon's DAMON Might Finally Be Ready For Upstreaming Into The Linux Kernel

At the start of 2020 Amazon engineers sent out a "request for comments" around DAMON as a new kernel feature to monitor data accesses and can be used for purposes like analyzing over-committed memory use, debugging, and other optimizations. DAMON has now seen thirty-four revisions to the patches but it looks like it could finally be in a state for mainlining in the Linux kernel...

Data mining right from the kernel, using YOUR hardware to reduce the load on their datacenters. Bill M$ forgot to think about that...

they should have called it DEMON

It's probably that attitude that's responsible for Linux's OOM killer still being garbage. How are you going to fix the problem if you don't have an open-source (i.e. auditable for data exfiltration) way to monitor how programs use memory?

squint squint, I smell evil...

Try looking up something on Ali and then wonder why Amazon is bombarding you with 'better' offers.... A commercial corporation does never do anything for free.

They probably just want the Linux kernel devs to maintain it for free as internal kernel APIs get rewritten. That's typically the reason you upstream something that's not part of your business's secret sauce.

Like I said, nothing comes free...

And? That's what the kernel devs chose to agree to. you upstream something and they'll refuse to accept contributions elsewhere that change the APIs it depends on without also updating it to stay in sync.
