@Woodstock --> Can you set the RTI wheels in motion for fenix illumos#17781 ?

BUG 17781: swprintf(3c) does not work properly (New)

↳ illumos.org/issues/17781 | code.illumos.org/c/illumos-gate/+/4729

danmcd: will do

rmustacc: I broke fmd's ses in the merge, do you know where logs about those things live?

hi, so I'm trying to boot illumos (i've tried latest omniosce stable, lts, and bloody; also openindiana) on qemu 11.0.0 and I keep getting this page fault, consistently: usercontent.irccloud-cdn.com/file/cmBY9w4H/image.png I've tried playing with KVM vs no KVM, cpu types, no dice. any ideas? command line is "qemu-system-x86_64 -cdrom ~/Downloads/omnios-bloody-20260319.iso -m 8G --no-shutdown --no-reboot"

FTR i'm on an amd ryzen 9 9900X but I can repro this with KVM and _without_ KVM, so I don't think that's the problem

@heat it's at CPU bringup time... and you just confirmed it fails this way on the bare-metal, too?

i didn't try this on bare-metal, closest to that was qemu + kvm

Okay... it MAY be some smbios thing. real_mode_stop_cpu_stage2_end+0x7171 is a call to smbios_open().

Lots of missing stack between that and the bcopy.

we had an arm bug on a freebsd host where the smbios just wasn't there, and we did something like that.

ok! so I tried OVMF to rule out BIOS vs UEFI, and OVMF seems to boot

smbios_open() calls bcopy 7 different times, and THAT's assuming bcopy isn't getting called further deep into smbios.

Thanks @richlowe. :)

so whatever seabios is giving illumos, it's not enjoying it too much

Yeah... probably not. :)

we failed earlier on arm most recently I guess, but the problem was we took the x86 code to find the SMBIOS tables in the old mpbios way where you scan low memory for a magic string.

and that's bad news both in general in a machdep way, and in specific if you don't find one I think?

I sure am glad someone made fmd's option stuff as baroque as possible

xD

for the IRC log searchers: the answer is `(cd /; /usr/lib/fm/fmd/fmd -o fg=true -odebug=all -odbout=stderr)` you need to `cd`, fmd doesn't.
