@fgaz:matrix.orgfgazand apparently spacemit m1 based stuff also goes up to 16G but it isn't faster than vf2 despite the higher core count08:41:45
@skeuchel:matrix.orgSteven KeuchelPioneer has more cores, but the cores themselves are slower.08:41:47
@qyliss:fairydust.spaceAlyssa RossPioneer seems unavailable anyway08:48:23

In reply to @fgaz:matrix.org
there's the milk-v pioneer, but it's pricey. alternatively, EIC7700X boards (milk-v megrez, pine64 starpro64) go up to 32G but they are all out of stock
Any idea how mainline support is for the EIC7700X boards?
08:49:45
@skeuchel:matrix.orgSteven KeuchelNo mainline support yet. Vendor kernel needs some custom CONFIG values to compile on Nixos.08:57:23
@qyliss:fairydust.spaceAlyssa Rossyikes08:57:39
@skeuchel:matrix.orgSteven KeuchelAt least the vendor uboot has distro boot enabled by default.08:57:57
@qyliss:fairydust.spaceAlyssa Rossmaybe visionfive is the way to go then08:58:04
@skeuchel:matrix.orgSteven KeuchelDepends on what you want to do.08:59:02
@qyliss:fairydust.spaceAlyssa Rossmostly I want to test generic OS images I'm building, so only systems with good mainline support are really interesting09:00:33
@fgaz:matrix.orgfgazthen vf2 is 100% the way to go at the moment09:01:42
@skeuchel:matrix.orgSteven KeuchelAnd you build those through cross compilation or do you want to build them on the device?09:02:25
@qyliss:fairydust.spaceAlyssa RossNative09:03:01
@fgaz:matrix.orgfgaz * then vf2 is 100% the way to go at the moment ah right native compilation 09:04:13
@qyliss:fairydust.spaceAlyssa Ross(I know it will be very slow, that's fine)09:05:06
@fgaz:matrix.orgfgazthe "low" amount of RAM is also a problem for some packages, but a bit of swap is enough to compensate in my experience09:07:51
@fgaz:matrix.orgfgazunless you want to build a browser09:07:54
@qyliss:fairydust.spaceAlyssa RossI would ideally like Firefox but I can live without it09:08:38
@qyliss:fairydust.spaceAlyssa RossApart from that I don't think there's anything particularly big09:08:52
