<somlo>
davidlt[m]: I'll start by studying what actually happens during "Terminate Plymouth Boot Screen", maybe I can narrow down what's actually happening under slightly more controlled conditions
acharles has joined #fedora-riscv
<somlo>
I removed all plymouth services from the sdcard and tried again, still getting kernel panics, so the plymouth thing was most likely a coincidence
<javierm>
somlo: probably is whatever service is executed after plymouth quit and that triggers the panic. So plymouth was a red herring
<javierm>
somlo: can you get more debug output from your initrams? for example in fedora I usually boot with rd.debug for dracut but don't know what would be in your distro if using initramfs-tools

iooi_ is now known as iooi
<davidlt[m]>
nirik: is /mnt/koji in Fedora an NFS mount? What's the backing storage solution? GlusterFS? Ceph? Something else?
<nirik>
davidlt[m]: it's a nfs mount from a netapp. :)
<davidlt[m]>
I see
<djdelorie>
davidlt[m]: today, I see a couple of expect's running, one using 14 hours of cpu. But various gcc backends keep running, so it looks like it's testing
<davidlt[m]>
Yeah, it seems to be going forward.
<davidlt[m]>
Slower then I would expect thus I am not touching it :)
<neil>
btw, happy to volunteer my board if it would help :) it's the starfive visionfive v1 with the jh7100
<davidlt[m]>
We don't have support for JH7100. The target is JH7110.
<neil>
yeah i guess i've got an older image booted on it. i've got some of the 7110's coming from their kickstarter eventually
<davidlt[m]>
Yeah, JH7100 has too many issues and that's a test chip.
<davidlt[m]>
JH7110 should provide what we need, but slightly less RAM.
<neil>
So what boards are you folks using right now? or just emulated ?
<davidlt[m]>
Unmatched
<davidlt[m]>
Basically exclusively Unmatched these days
<davidlt[m]>
Until JH7110 (VisionFive V2 and PINE64 Star64) and SiFive/Intel P550-based board shows up.
<davidlt[m]>
There might be a T-HEAD C910 based boards showing up too. Those probably would get support too.
<davidlt[m]>
We will need to do something custom for JH7110 until upstream support arrives.
<neil>
ah, I see. that makes sense :)
<davidlt[m]>
I already raised my opinion with them -> start sending minimal boot patches now.
<neil>
where does the SiFive X280 fall in?
<neil>
(if at all)
<davidlt[m]>
Well that's an AI stuff. U74, typically 8 cores with vector support.
<davidlt[m]>
While it can run Linux it mainly targets AI stuff.
<davidlt[m]>
NASA selected X280 to fly to space a day ago :)
<neil>
:D I saw! (thus the question heh)
<davidlt[m]>
You can think of it as a small version of Intel's Xeon Phi :)
<davidlt[m]>
Really a cool product if you have specific AI/ML needs, but doesn't target "Performance" (That's P550, P650)
<davidlt[m]>
The U74 is considered "Essential" or low-power low-performance category.
<davidlt[m]>
U74 is like Cortex A55.
<neil>
oh, I see. I don't think I realized that, but it does make sense
<davidlt[m]>
Microchip also makes SoC and dev boards. Those are based on U54, or SiFive HiFive Unleashed level.
<neil>
my wife's going to hate me soon :P
<davidlt[m]>
But sadly even lower performance (power consumption was the main thing for that design).
<davidlt[m]>
Why is that?
<neil>
buying too much hardware :P
<neil>
been lots of small computers purchased this year haha
<davidlt[m]>
Welcome to the club :)
<davidlt[m]>
I am opening a datacenter next to my desk :D
