@rosscomputerguy:matrix.orgTristan RossLol, GHC on my Ampere Altra Max is done fast18:14:05
@alex:tunstall.xyzAlexI'd believe it, <2h on my desktop.18:14:20
@rosscomputerguy:matrix.orgTristan RossTakes like 15 minutes for me18:14:52
@rosscomputerguy:matrix.orgTristan RossMost packages on Ampere don't go over an hour.18:15:14
@lotte:chir.rs@lotte:chir.rsthe most annoying package i do regularly raccompile is a patched rpi kernel18:19:10

@rosscomputerguy:matrix.org one week continuous building? best advertisement for visionfive 2 i've heard
i've had zero stability issue on my (also 1.5GHz) star64 with this passive heatsink

@rosscomputerguy:matrix.orgTristan Ross1,693 derivations built now.02:29:05
@rosscomputerguy:matrix.orgTristan Ross216 hours02:31:04
@rosscomputerguy:matrix.orgTristan RossAverages 7.8 derivations an hour02:31:33
@rosscomputerguy:matrix.orgTristan RossIt is built05:49:23
@hsngrmpf:matrix.orgDavHauWas this native vor with emulation?06:43:50
@oak:universumi.fioak 🏳️‍🌈♥️ changed their display name from oak 🫱⭕🫲 to oak.10:58:24
@oak:universumi.fioak 🏳️‍🌈♥️ changed their display name from oak to oak 🏳️‍🌈♥️.11:00:33
@rosscomputerguy:matrix.orgTristan RossNative, I can't do emulation13:44:07
@rosscomputerguy:matrix.orgTristan RossEmulation doesn't quite work with a 64k page size on Ampere13:44:18
@rosscomputerguy:matrix.orgTristan RossCross compiling though took 40 minutes on Ampere13:44:30
@rosscomputerguy:matrix.orgTristan RossNative building took like 9 hours and 30 minutes13:44:43
@rosscomputerguy:matrix.orgTristan Ross* Native building took like 9 days and 3 hours21:32:37

@hsngrmpf:matrix.orgDavHauI'm cross compiling my starfive as well. 9 days sounds crazy. Is this due to slow flash IO, or is the CPU the limiting factor?03:22:39
@alex:tunstall.xyzAlexIIRC it's mostly CPU-limited.03:34:10
@hsngrmpf:matrix.orgDavHauWow, this sounds unreal? Is it just that compilers etc. are not optimized to run on riscv?03:53:33
@dramforever:matrix.orgdramforeverthe visionfive 2 is just not a great cpu05:13:48
@dramforever:matrix.orgdramforeveri mean the jh7110 on it05:14:35
@dramforever:matrix.orgdramforeverthey had to rush the release to be before the th1520, otherwise they couldn't even have the claim to be the fastest riscv sbc at release05:15:21
@lotte:chir.rs@lotte:chir.rsio speed is quite good05:22:53
