Where does this fit into the boot sequence? Do you have a link for more about this?

Operating Systems and Porting / Re: kernel config: page size 4k vs 64k
« on: February 04, 2021, 12:38:30 pm »
cchincz, as MPC7500 correctly points out, they are both 4-core CPUs -- the "16 CPUs" are an artifact of SMT -- and optimization is still a problem for some programs. This is improving slowly. For example, we now have better SIMD in Firefox and in other media packages.

Talos II / Re: Advice for installing OS via BMC?
« on: February 02, 2021, 07:29:38 pm »
Don't reuse the BMC's IP, you may need it to ssh into it. However, it does share the first Ethernet port. Void Linux should boot like a champ; so should Fedora.

Grrr, that sounds like kvm_pr got broken again. I'll take a look.

Operating Systems and Porting / Re: Fedora 34: going to 4k page size? Help needed
« on: January 08, 2021, 05:12:28 pm »
I see sharkcz is already involved in this conversation. I personally am not aware of anything that would break as a result (in fact, as you correctly point out, many things would suddenly "just work"). My only hesitancy is it would make 64K page kernels more of a pariah than they are already, sort of like another situation with big-endian, and there are performance reasons for 64K pages. Might this, perhaps, be a Workstation-only change and keep the performance benefits for Fedora Server?

Applications and Porting / Re: Wayland support/port for PPC64el
« on: December 30, 2020, 07:51:28 pm »
Why would Wayland make a difference? Who told you that?
Wayland has been the default for GNOME since F25, though I use Xorg.

Yes, I'm certainly prepared to admit that gdm is part of the problem. A lot of things worked better without it.

I don't see your fixed patch?

Wayland works "fine" (for various values of "fine") if you have a GPU. Or I should say, my objections to Wayland remain the same on my T2 as they do on x86_64.
My BMC-only Blackbird ran like glue with Wayland, and this was acknowledged (for various values of "acknowledged") by a Wayland developer I consulted with about it. This did seem to improve in Fedora 33, possibly due to other improvements such as in llvmpipe, but it can't be tricked into generating any larger displays so far: https://www.talospace.com/2020/11/fedora-33-mini-review-on-blackbird-and.html
I should also note I am no longer running gdm at all. I boot to a text prompt and start Xorg or Wayland manually. This also solved a lot of problems.

Nice work. I just use my own huepl utility on mine, but I've been thinking of expanding what home automation features it can control.

Blackbird / Re: LPC Guard questions
« on: December 25, 2020, 06:50:27 pm »
Although Raptor can confirm, my bet is it's implemented. The way it's described in the update, the kernel wouldn't need to be aware of it.

Blackbird / Re: mainboards on backorder
« on: December 25, 2020, 06:44:14 pm »
Yes, having a second system is a good idea. My Blackbird serves this role for my T2.

I think it might be the controller as well. Do you have a PCI one you can try?

Myself, I'd probably prefer the DD2.3 stepping because I need proper DAWR support for development. Was there a price range quoted?
