@iximeow --> 22min build time!!! What nightly(1onbld) options did you use for that ( fenix illumos#17565 ) build?

BUG 17565: mdb: ::cpustack should survive bogus CPU numbers (New)

↳ illumos.org/issues/17565 | code.illumos.org/c/illumos-gate/+/4361

Also, CPU/RAM/disk combos? My Ryzen 3700X does NIGHTLY_OPTIONS="-ADCmnprft" in 40mins.

[illumos-gate] 17565 mdb: ::cpustack should survive bogus CPU numbers -- iximeow <illumos⊙in>

danmcd: I have an AMD EPYC 7402P 24-Core (2800 MHz) which I think does an RTI build in 31 minutes

mail_msg reports the actual build part as 10:43 for DEBUG and 11:54 for non-DEBUG

3x cores 10min (25%) savings from my 3700X. That makes me feel less jealous. I'm unsure what iximeow has but I really wanna know.

I have an AMD EPYC 8224P (also 24-core) with similar build times. the mostly-single-threaded post-build housekeeping stuff really starts to dominate the wall clock time with that many cpus.

there's a handful of big-directories that show up annoyingly in pgrep as if they matter, too

[illumos-gate] 17562 cxgbe could reclaim more gracefully -- Patrick Mooney <pmooney⊙pc>

my dream for a build system that knows history, and schedules the subdirectory-ful bits of cmd/ first

my dream is to finish my revised make parallel job governor and then take the brakes off in the makefiles

(this includes having cw playing along with it so cw with main+shadow+smatch counts as 3 jobs while all three are running..)

that would be good, and job governing that made sense too (though that's a compatibility shock, given how differently our -j N and a competent one work)

should you do the fifo semaphore, and suddenly everyone's -j 32 actually means _32_ and not 32^depth

though under normal circumstances, we build everything after the tools build with the new make so the main worry for compat shock would be make clean/make tools

danmcd: i'm *pretty sure* it's NIGHTLY_OPTIONS="-nCDAprt" (several months ago i put together a ./prep_mailmsg.sh that drives basically all of it, 'cause i often forget to build just the one new patch on whatever the tip of the gate is)

but, 7950x with... some ECC RAM at a reasonable-but-not-Gamer speeds and an nvme disk it all lives on

the real trick is that ./prep_mailmsg ends by echoing \a a few times so i... run it in a shell and forget about it for a bit while i'm doing other things :D

ah, the memory is 3600 MT/s and the disk is a 2TB 970 EVO Plus

til nightly -m which is probably better than having a bell :)
