@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
@lotte:chir.rs@lotte:chir.rsespecially if you have an nvme ssd05:23:04
@dramforever:matrix.orgdramforeverit's not great for an nvme, not even great for pcie2.0x1 but it's much better than any sd card05:24:17
