geist: I'm running 22.10 on a single core, uniprocessor D1 SBC (Lichee RV), just need something to that's faster at building so I can stock upstream to test.
<sevan>
build*

On the Lichee RV it takes a while to boot, I assumed it was just really slow but now booting under qemu, there's a huge delay between EFI handing off and the kernel starting to load. The disk image is on nvme so it's not a sd card issue...
<sevan>
boot is fairly quick, opensbi does its thing, then grub menu, then it reports:
<sevan>
EFI stub: Booting Linux Kernel...
<sevan>
EFI stub: Using DTB from configuration table
<sevan>
EFI stub: Loaded initrd from LINUX_EFI_INITRD_MEDIA_GUID device path
<sevan>
EFI stub: Exiting boot services...
<sevan>
and it sits there :)

for how long? does it pick it up eventually? I've seen a good 20 secods or so there
<sevan>
a couple of minutes, I'll try again in a mo, I booted without any networking configured on the qemu side
<sevan>
once the kernel starts it's quick at probing things and then going multi-user. It's slowly working through the services atm
<geist>
depends on the host machine too, of course. on my ryzen 3950x i've observed that qemu 7.2 runs the Rv ubuntu at approximately say 600mhz or so. actually pretty similar to a sifive unleashed
<geist>
whichi s about right, based on completely bespoke benchmarks that's about a 8x slowdown from the host machine, which tracks based on past observations at how fast qemu is at running things
<sevan>
host is arm64, no shiny ryzen :)
<geist>
yah that might be where you're seeing an additional slow down, especially if it's a a53 or so
<sevan>
yep, i.MX8MQ
<geist>
yah that tracks, so a few minutes may be in line, since it may be say 4 or 5x slow host machine wise than my experience, and i think i see a good 20-30 second gap there too (assuming the gap is something computational)
<sevan>
what's happening during that gap? it's just reading the kernel into memory, right?

a good question. probably worth breaking into it and seeing what the cpu is up to

geist: I guess I need to envoke qemu with the monitor mode enabled then :)
<geist>
yah i usually run it -nographic and then you can break into the monitor with ctrl-a c
<sevan>
ah, ok. I already did that from copying the wiki article snippet

fyi for those also in Brussels for FOSDEM - I'm looking to get some risc-v folks together tonight. I'm already in contact with several people but if anyone wants to ping me I am +1-773-710-7131 on signal/whatsapp/telegram.
<rneese>
no your not allowed to
<rneese>
its not fair to those of us who cannot be there
<rneese>
lol
<rneese>
morning drew
<drewfustini>
hi, good morning :)
<drewfustini>
I wish there was something like FOSDEM in US too. I would say the closest might be SCaLE in LA
<rneese>
Would have to have a Eastcoast Meeting

drewfustini: I'm at my layover in CPH right now I'm on SK 597. I think my Euro SIM isn't working, though (unless I'm not in the EU?)
<drewfustini>
Hmm, that should be the EU.
<palmer>
ya, that's what I thought
<drewfustini>
It's not always great reception, but I do appreciate traveling with Google Fi.
