Blackbird / Re: Issue with blackbird booting with GPU

« on: September 13, 2022, 11:06:06 am »

How is your TalosII configured to boot faster? Or do you use !BMC?

Sorry if that was unclear: I meant with fast reset on. It's just that it fails so often that it doesn't seem worth the modest improvement, at least on my machine.

Is there pretty good support for the wx series card in fedora? I've thought about getting a wx2100 or wx3100 for my blackbird to have a little lower power card.

I use a Raptor BTO WX7100 in my Fedora 36 Talos II, and it's fine. The fast reboot problems I mention are with other devices. I do have the firmware loaded in BOOTKERNFW so I can access Petitboot.

Fast reboot isn't much faster? It saves me 90 seconds if active.

Maybe it's the way my T2 is configured, but while I agree it's quicker, I don't find it *much* quicker. Plus, when it muffs it, you end up doing a full reboot anyway.

Why would you do otherwise? Since it's a source of entropy, virtualizing it would potentially compromise the cryptographic security of the guest. RDRAND on recent (Ivy Bridge at least) x86_64 is the same way. See https://lwn.net/Articles/887207/ for an example of when this goes wrong.

They really should just ship that way. Fast reboot isn't much faster than regular rebooting, even when it works (which is about half the time).

Nice work.

Do you have fast reboot still on?

Something like nvram -p ibm,skiboot --update-config fast-reset=0 as root should disable it.

Does messing with cpufreqctl help any? What does it say the current frequencies are? What does `sudo cpufreqctl --throttle-event` come up with (or `--throttle`)?

Neat! I couldn't tell what he was breaking apart at 5'26" though.

I'm holding out for P11 myself.

Correct, they do not need to match. That said, I like the symmetry.

Never seen that on my T2 (dual-4 or the current dual-8 with HSFs). How many cores, what type of cooling, and what were your core temperatures?

Talos II / Re: ipmi_sdr_cache_create: SDR record count invalid

« on: August 24, 2022, 03:39:17 pm »

No, I get this on all my systems, so I don't think there's anything wrong with your specific hardware (one can argue about whether the SDR records are misconfigured, but that's separate). I don't know why this isn't the default.

That said, I just use ipmitool, not ipmi-sensors.

What's with the compiler issue just curious

I'm getting odd errors from gcc building current Firefox in debug (per @sharkcz it does work in opt). I'm toying either with downgrading or using clang for this go-around.

I'm having trouble even with 5.18.18 (SATA devices not showing up). I'm still on 5.18.13 so my optical drives work.

Good to hear about GNOME, but I've mostly gotten KDE Plasma working the way I want it on F36 and it's a lot snappier.

Right now my showstopper is compiler issues.
