@imil I patched Firecracker to use that CPUID leaf. I can't remember if that patch got merged though; at one point it was being held up because there was work in progress to change how Firecracker did it's CPU config stuff.

@emaste @david_chisnall @encthenet If you can provide scripts I'd be happy to run them on EC2 as part of my weekly snapshot regression testing. I think bofh is going to be giving me some scripts for testing build reproducibility soon too.

@david_chisnall @encthenet @emaste In fact the January 2024 regression is what prompted me to start collecting and graphing this data regularly. It took way too long for me to notice that issue.

@david_chisnall @encthenet @emaste The jump in January 2024 (main) and July 2024 (stable/14) was an EC2 issue related to the snapshot size; as you can see, now fixed. No idea what happened with stable/11 and I don't think it's worth investigating.

@encthenet Yeah I need to look up how to put text sideways in mpgraph.

@encthenet @emaste Looks like "-alpha remove" does what I wanted. This looks good with no bogus transparency right?

@emaste BTW the big improvement a few weeks ago was fixing the EFI RNG code -- arm64 was hanging waiting for entropy.

@encthenet @emaste Sorry, generated with metapost+latex and converted from PDF to PNG with imagemagick. Not sure what the magic is to remove transparency.

@emaste @ChuckMcManis @frameworkcomputer Now available, BTW.

@emaste @ChuckMcManis @frameworkcomputer Thursday around noon PDT. The builds start at midnight UTC.
