General CPU Discussion / Re: CPU Performance DD2.2 vs DD2.3 (v2)
« on: May 03, 2020, 06:07:58 pm »
I'd strongly recommend you were on at least system package 2.00 for DD2.3, yes. It might be glitchy on earlier releases.

Operating Systems and Porting / Re: [NEWS] Fedora 32 is released

F31 is still going to be supported for a little while, so there's no hurry to upgrade if you're concerned about it.

It looks like its the 190w variant:
Yes, 02CY489 is a DD2.2 18-core @190W.

... and, double derp, I could have just asked lshw. Indeed it is 02CY649.

Derp. It would have been a good idea for me to actually check the number before I installed it, but Raptor's specs (mostly) match the 02CY649.

Yes, it should "just work."

Do other CPU choices or changing the number of cores make any difference?
I run a homebrew QEMU and compile directly from source with -O3 -mcpu=power9. It's not super-fast running x86_64 code either, mind you. TCG is heaps better than interpreted code but even so it's still relatively simplistic.

Blackbird / Re: Keyboard unresponsive at boot menu (Petitboot)
« on: April 25, 2020, 01:46:17 pm »
The difference is whether you have a GPU installed or not. If you don't, then everything appears on the on-board HDMI 2D framebuffer, which is driven by the BMC, including Hostboot and the Petitboot menu. My Blackbird is set up that way.
If you have a GPU installed and you jumpered it so that the GPU is used, then you may need to put the GPU's firmware into PNOR so that Petitboot will work with it (note that you will not see the earliest Hostboot sequence and nothing will appear until you get to Petitboot). If you don't do this, the system will run, but you won't see anything until the main OS starts. See https://wiki.raptorcs.com/wiki/Add_GPU_Firmware_To_BOOTKERNFW

Firmware / Re: How to setup Secure Boot with PetitBoot
« on: April 25, 2020, 01:41:36 pm »
OpenBMC runs on the BMC (the ASPEED chip on the board). That's an ARM core. It starts the main POWER9 processor(s) and Skiroot/Petitboot run natively from there; the BMC keeps on doing what it does.
The Secure Boot process looks like this: https://www.ibm.com/developerworks/library/l-protect-system-firmware-openpower/index.html

Mod Zone / Re: Low profile heatsink?
« on: April 25, 2020, 01:28:02 pm »
I have the 2U heatsink on my 4-core Blackbird. Depending on environment I would personally consider an 8-core thermally constrained in a low-profile case without the full 3U HSF, though mine is also crammed into an mATX HTPC case under an AV receiver with a bank of case fans on the side pumping air out.

That is indeed a pretty bleeding edge and I'm impressed by the lengths you went to. I'm leery of how well that would work under load, however (or for how long). What types of tasks is it doing? How does it perform if the CPU slices are loaded? Do you notice any throttling behaviour?

I've got RtCW also on this machine. A couple glitches but generally works fine. I used the icculus version (iortcw).

No, I mean, what arguments are you passing to QEMU? Did you build QEMU yourself, or are you using a package?

For the T2, you really want both processor sockets filled, or you lose slots (because the CPUs provide the PCIe lanes; it's not something Raptor did to make you buy more than you need). A single-socket T2 would only be useful if you didn't need the expansion and I do. That's really the sales case for the T2 Lite anyway (you need more threads than a Blackbird can handle, but you don't need the expansion options of the full T2).
Anyway, it didn't start off swimmingly but for various reasons not all due to that system specifically. Fortunately things are back in order and I'll have more to say about it when I finish getting all the pieces back together.
