This week Michael Hudson-Doyle of the #Ubuntu Foundations team published a write-up of our experimentation with the `-O3` GCC flag by default in the distribution.
The tl;dr is that we don't yet believe that the change makes sense globally, but there are certainly come packages that would benefit from using the increased optimisation level.
See the post here: https://discourse.ubuntu.com/t/benchmarking-a-distribution-and-some-o3-results/58027

@karppinen I still don't want to spend of my personal money as much as it costs so I review the patches by emulating SGX in my head while looking at Intel SDM :-) Testing is based only on compilation.
I do run final test on NUC7 tho but it does not really give sufficient information whether a feature is actually right.

@oceanhaiyang it still was funny and not being real sort of fits to the overall picture :-)

@oleksandr Yeah, well I'm talking about what exists widely :-)
The solution that AMD and Intel provide is to subscribe to their developer programs and get "cloud access". Or something like this was proposed last time I asked about this.
One working alternative would be to provide full QEMU emulation support (which of course cannot do attestation but that does not matter for kernel).

IMHO, AMD, Intel and ARM should step up and start provide some cheap and accessible hardware that you can use at your home, and not intended for rolling out cash (i.e. something like NUC), but only to allow kernel maintainers and operating system developers to test their server features.
Cheap means here something like less than 1000 euros.
E.g., in Intel SGX the latest and greatest are NUC7's from 2018 and for VM based confidential computing there's nothing appropriate.
Shame on you CPU companies!

E.g., what if there was acknowledgements where the author at least would say that now I'm going to give my wife equal opportunity to focus on her career while I take care of the kids? ;-)
If I ever write a book, I promise not to thank you any of my family members, just because it has so large hypocrisy factor :-) And also to respect privacy e.g., of my girlfriend.
