@dramforever:matrix.orgdramforeverbut i don't think llvm is getting that any time soon, or ever10:30:11
@zimward:zimward.moezimwardfun stuff. but sounds like it should be an issue in all C920v1 cores10:50:04

I have both the pioneer (sg2042) and the megrez (eic7700x). the c920 cores in the sg2042 are kinda slow. too slow to use as a desktop. and a lot of processes swamp the memory subsystem. the p550 are already much faster. I would estimate that 4x eic7700x might outperform the sg2042, and would probably also be cheaper.
Matthew Croughan has a P550 and I've tried compiling things on it. We've seen a lot of things fail on it which makes me think there's something wrong. How does it perform for you?

fail as in...?

@dramforever:matrix.orgdramforeverrandom userspace crash?13:59:55
@rosscomputerguy:matrix.orgTristan Ross A lot of test failures like bus errors and io errors 14:00:21
@skeuchel:matrix.orgSteven KeuchelIt's not as stable as I would like because the board crashes about once a week, but I am not running into the problems you describe. I have fewer tests timing out than on the sg2042, and other test failures are clearly software, not hardware related.14:06:57
