@samueldr:matrix.orgsamu�drlike 2h max for a 6.x kernel21:18:44
@elvishjerricco:matrix.orgElvishJerriccoI could also just do binfmt. That might be best.21:18:48
@samueldr:matrix.orgsamu�dr * like 2h max for a 6.1 kernel21:18:51
@samueldr:matrix.orgsamu�dr * like 2h max for a 6.0 kernel21:18:57
@elvishjerricco:matrix.orgElvishJerriccoIIRC the Pi takes like 1h for a kernel build.21:19:02
@elvishjerricco:matrix.orgElvishJerriccoMight be misremembering. I have it running such a build right now to see21:19:13
@samueldr:matrix.orgsamu�drdepends what you are building, and I also didn't time it21:19:48
@samueldr:matrix.orgsamu�drI just remember it taking more than 30 minutes, less than half a day21:20:11
@samueldr:matrix.orgsamu�drthe three buckets of build time: less than 30 minutes, more than 30 minutes, more than half a day21:20:31
@elvishjerricco:matrix.orgElvishJerriccohah that's fair21:20:45
@kfears:matrix.orgKFears (23.11.2022 when)Does Oracle still give out free ARM VMs?21:22:15
@samueldr:matrix.orgsamu�drthat's my assumption21:22:38
@elvishjerricco:matrix.orgElvishJerricco Based purely on how fast the make targets are scrolling by, it looks like nixbuild.net is roughly as fast as my macbook's aarch64 linux VM. I wonder if they just bought some apple silicon macs to support aarch64-linux. 22:10:00
@samueldr:matrix.orgsamu�drI think they're using one of the aarch64 offerings, maybe amazon22:10:26
@samueldr:matrix.orgsamu�dr * I think they're using one of the aarch64 cloud offerings, maybe amazon22:10:32
@elvishjerricco:matrix.orgElvishJerriccoyea that would probably make more sense :P22:10:38
@samueldr:matrix.orgsamu�drbut storage speed helps a lot with loads-of-small-bits to build22:11:08
@samueldr:matrix.orgsamu�drand is likely why on not-actually-a-raspberry-pi-4 you had good results22:11:38
@elvishjerricco:matrix.orgElvishJerriccoI dunno. IIRC I tried testing a nix build of the kernel with /tmp on tmpfs vs zfs and it didn't really make a difference22:11:47
@elvishjerricco:matrix.orgElvishJerriccothough22:12:01
@elvishjerricco:matrix.orgElvishJerriccozfs was on nvme22:12:04
@samueldr:matrix.orgsamu�dryou likely were already over the hump22:12:06
@elvishjerricco:matrix.orgElvishJerricconot sd card :P22:12:08
@samueldr:matrix.orgsamu�dr * you likely were already over the hump22:12:19
@samueldr:matrix.orgsamu�drexactly22:12:22
@elvishjerricco:matrix.orgElvishJerriccoyea and my cm4 is using nvme for this test22:12:32
@samueldr:matrix.orgsamu�drfast storage against marginally faster storage won't help22:12:37
@samueldr:matrix.orgsamu�drespecially if that RAM could have been used for something else22:12:52
@elvishjerricco:matrix.orgElvishJerriccoIt's an exciting drag race though. CM4, vs nixbuild.net, vs Threadripper 1950X + qemu, vs Apple M1 Pro VM, vs Ryzen 7950X + qemu22:13:47
