01:58 <samueldr> good news, aarch64 can be built quickly looks like

01:58 * samueldr wonders about timeouts

01:58 <gchristensen> 11h to build all but 88 of 22,000 packages

01:58 <gchristensen> (88 still building and I'm not waiting up)

01:59 <gchristensen> timeouts?

01:59 <samueldr> (unrelatedish)

01:59 <samueldr> https://hydra.nixos.org/build/95091823

01:59 <samueldr> llvm often times out on aarch64

01:59 <samueldr> oops, restarted it

01:59 <samueldr> "often"

01:59 <gchristensen> interesting

01:59 <samueldr> it doesn't need to be rebuilt that often

01:59 <samueldr> not specific to a channel

02:00 <samueldr> I think it's just being sent to not the optimal machine?

02:00 <gchristensen> big-parallel / core allocation maybe

02:00 <gchristensen> yeah

02:08 <gchristensen> ok past my bed time.

02:17 Guest77 has joined #nixos-aarch64

02:19 <samueldr> hmm, almost everything that timed out timed out on qtwebengine

11:02 <lorem_ipsum> hi

11:02 <lorem_ipsum> i am currently trying to setup a pi with the aarch64 image, but I am failing to get openssh to start

11:02 <lorem_ipsum> first time nixos, so maybe some other faults, but what I did: flash new image, boot, edit /etc/nixos/configuration.nix

11:03 <lorem_ipsum> added services.openssh.enabled = true; and ran nixos-rebuild switch

11:03 <lorem_ipsum> rebuild runs oom, add swap, run again, finishes, but sshd is not started

11:04 <lorem_ipsum> there is also no symlink in /etc/systemd/system/multi-user.target.wants

11:04 orivej has joined #nixos-aarch64

11:04 <lorem_ipsum> am I doing something wrong, or do you have any suggestions on what to check?

11:13 Guest77 has quit [Quit: My MacBook has gone to sleep. ZZZzzz…]

11:16 <lorem_ipsum> seems to be this issue... https://github.com/NixOS/nixpkgs/issues/26776

14:29 <gchristensen> samueldr: https://turingpi.com/

14:37 <gchristensen> bummer. v8

15:27 <samueldr> v8?

15:28 <gchristensen> compute 3, 3+

15:28 <samueldr> still not sure what v8 relates to

15:28 <gchristensen> itis armv7

15:28 <gchristensen> erm

15:28 <gchristensen> armv8

15:29 <samueldr> ah, "it's not armv6"

15:29 <samueldr> yeah

15:33 <samueldr> gchristensen: if you wanted to analyze before I requeue https://hydra.nixos.org/build/95091823

15:33 <samueldr> llvm

15:33 <samueldr> hmmm, not a time out

15:33 * samueldr shared too quickly

15:37 <samueldr> maybe there's still a bit of analysis to do: what machine type, is the failure reproducible?

15:38 <gchristensen> can look soon

15:38 <gchristensen> writing an email to the rpi foundation

15:40 <gchristensen> hmm

15:41 <gchristensen> recent two are ampere

15:43 <gchristensen> oh samueldr maybe this is the firmware bug

15:43 <samueldr> it would be prudent to isolate an ampere machine, and build to confirm

15:43 <gchristensen> yeah

15:43 <gchristensen> want me to give you one?

15:44 <samueldr> going to get busy in the day, so don't know if I'll be able to follow through

15:49 <gchristensen> sure

15:50 <gchristensen> I can add you anyway

15:50 <gchristensen> I took it outof hydra and will try building it

19:25 <samueldr> ah, so I gather it coincided with a staging merge?

19:27 ryantrinkle has joined #nixos-aarch64

19:27 <gchristensen> I think it has just been luck for the past $while that it was working

19:28 <samueldr> right, aarch64 failures being ignored as it eventually built on non-ampere?

19:28 <samueldr> (now I have read the things)

19:30 <gchristensen> right

20:58 <gchristensen> omg samueldr do you know about gumstix' geppetto?

20:59 <samueldr> soon I will

20:59 <samueldr> oh, colour me surprised

20:59 <samueldr> I thought it was _a_ product

21:04 <samueldr> that's an exciting thing

21:04 <samueldr> though I'm scared of what pricing will be

21:04 <gchristensen> probably not insignificant

21:12 <samueldr> it is fun, though

21:12 <samueldr> oof, if it wasn't for the setup price, it would be fine

21:15 <samueldr> https://www.gumstix.com/ordering/geppetto-orders/

21:15 <samueldr> though, looking at my "design", I think there is something I overlooked earlier with the turing pi

21:15 <samueldr> it *might* be compatible with the CM1

21:15 <samueldr> https://www.raspberrypi.org/products/compute-module-1/

21:19 <samueldr> oof, if only, there are things I see in the builder that would be nice

21:22 <gchristensen> oh?

21:23 <samueldr> usb pin headers like on a motherboard

21:23 <samueldr> routing usb from a board to another

21:23 <samueldr> so here *in the board* the cm1 modules are routed to the cm3 module

21:24 <gchristensen> hmm

21:25 <samueldr> that 1999$ initial cost (plus 3 MoQ) is a killer for something that's for playing around though

21:25 <gchristensen> yes definitely

21:25 ryantrinkle has quit [Ping timeout: 245 seconds]

21:25 <samueldr> (though understandably so!)

21:26 <samueldr> ooh, processors too, not only COM modules

21:26 <samueldr> though not full blown ones

21:30 <gchristensen> dang that is so cool

21:32 <samueldr> hmmm, they don't seem to have network switch hw

21:33 <gchristensen> I think you have to add bridges

21:34 <gchristensen> not sure. it can definitely be done

21:36 <samueldr> bridges?

21:36 <samueldr> hm

21:36 <samueldr> I would have assumed you needed some hardware part for switching

21:37 <samueldr> I think the bridge is only for 1:1

21:37 <samueldr> well, you could probably 1:1 many times, but that's not ideal either

21:38 <gchristensen> ah mininodes' one uses ethernet to usb

21:38 <gchristensen> the CM doesn't have ethernet

21:38 <samueldr> well, it would have to be rpi->usb->eth->[*]

21:38 <samueldr> but still, [*] would be nice if it was an internal switch

21:38 <gchristensen> so right
