Re: Someone installed an aarch64 Christmas gift: There is now a ampere4 with 150 or so FreeBSD CPUs and 24 builders running in parallel [an ampere5 exists too]

There is another  new ampere* : ampere5 looks to be
another 160 core ampere ["(21%) 32.92" for a short
term load average]. It looks to be doing some
sort of experimental build of 150arm64:

Master: 150arm64-default-foo
Build : 2025-12-24_21h05m27s
. . .
Set:    foo
. . .

It is using 13 poudriere builders (Jobs Id's 01 .. 13).
It has been building for a little under 67 hr and has
18278 built 17839 remaining.

Note: "foo" is a poudriere Set name, which for normal
Package Builds is "default". And Build names that are
encoded date and time information is also not normal.
