Operating Systems and Porting / Re: [NEWS] Fedora 34 is out!

I tried upgrading the Blackbird the other day, and it wanted to downgrade a few packages, which seemed surprising.

Not sure what that means either. Maybe it's one of the underlying libraries which was fixed or upgraded in F34?

I'll be giving this a spin in a week or two. Blackbird first, then T2.

Well, as long as they haven't removed Xorg.

Nice. Welcome!

Good grief, that's exorbitant.

They'd still need PHBs to attach them to, and there is only a fixed number of PCIe lanes per processor. If you want oodles of NVMe, the big T2 (with both CPU sockets populated) is really your only option; everything else is a tradeoff. This T2 has two NVMe devices, plus video card, SATA (for the optical drives) and FireWire.

What do you have installed in your system? On my vanilla Blackbird (RAM, SATA SSD and BD-ROM, BMC framebuffer), I've never had an issue with Fedora installation or upgrades, so it could be hardware.

What happens when you try to? What do you see in dmesg?

I got your other E-mail. I'll have a look later today (working this weekend).

@pocock is right; I've seen such packages. It may come down to marking them outright or submitting patches for them to check at runtime.

I'm loathe to see 64K go away completely because there's a reason for its existence even though it's not relevant to many of us. More importantly, however, I guarantee IBM won't let it, because the big systems that pay the bills all use it, so whatever we can do to get it to coexist won't be fighting institutional inertia.

I'll have a look at this this evening, but assuming there is an issue, I can't really debug this myself because of the nature of my firewall.

I've seen that with Tiger updates. I think there is some glitch or inefficiency with supervisor level code (which makes sense with KVM-PR). I've had the best luck doing installs with TCG instead of KVM, which is most reliable, and then switching back.

Also note right now that as long as we advertise to the OS as a G4/7410, it will select the wrong dcbz size, which has memory impacts. I have code to monkeypatch the operating system but this is not suitable for mainline KVM. We could monkeypatch the kernel permanently in the disk image but this would have to be after all your updates are done.

The definitive solution is to advertise to the OS we're a G5, and then the right cache line size is used. However, this locks up the computer right now ...

My personal network security requirements are a concern for offering my own hardware to the project, but I like this idea.
