am, do we have problems with code.illumos.org? gerrit seems to be gone and git pull is also waiting....

ping appears to respond: code.illumos.org is alive

gerrit is showing 502 Bad Gateway

DUMB question. In mdb... can you somehow specify a demangled C++ symbol (e.g. `base::Allocate`) to get its address? Or is that way too complicated due to C++-isms (overloading, etc.) and you just have to cope with what you can discover from, say, a stack trace?

you can't, you have to use the mangled name

I've not thought about it if it's possible to go from the mangled name backwards or not (at least without additional context)

danmcd: I've seen you comment about disabling E-cores on Alder Lake. what's the rationale for that? lack of uniform performance, or something actually breaking? (is it just the bootleg AVX-512 only on P-cores, or something else?)

Is gerrit down?

since morning.

(my morning:)

any ETA?

no idea

jclulow is the person who usually puts gerrit back together when it falls apart.

technically bdha at least also can, but what tends to go wrong these days is "AI"

so the old days of one of us just kicking it as we walked past are probably gone

sommerfeld, danmcd: I'm interested in E v. P too

(not that I have any ideas, but arm64 has the problem, or will eventually)

though at least I'm pretty sure all arm cores do the same thing, at least, dammit intel.

(where "AI" is fundamentally "web crawlers that don't respect robots.txt")

richlowe: there are multiple dimensions to it, certainly. If the only difference between the cpus is performance it's a less serious issue than if they support subtly different ISAs

I think that the AVX-512-on-P-cores-only thing was "fixed" by intel disabling AVX-512 using progressively bigger hammers.

with interludes of bios vendors working around the initial disable

sillycross.github.io/2022/06/11/2022-06-11 is an interesting read - P cores seem to be rather unpredictable.

oh, that _is_ interesting.

I have restarted gerrit. Let me know if you're still having trouble.

thanks!

jclulow: yes, gerrit works, thank you!

jclulow: thank you!
