Operating Systems and Porting / Petite boot and encrypting /boot
« on: July 04, 2020, 04:45:14 pm »
Can Petite boot work with an encrypted /boot directory? I have seen several methods for setting this up but it looks like they go through GRUB. I may not understand this correctly, but doesn't Petite boot stand in for GRUB, when using Raptor systems?

Firmware / Updating firmware from the live host: possible?
« on: July 04, 2020, 04:36:43 pm »
I'm still trying to wrap my head around the 1.00 > 2.00 firmware update procedure.

It looks like the files need to be sent from another computer. Can this be done simply by wiring ethernet ports 0 or 1 directly to the BMC ethernet port?

I would rather avoid having to trust another computer in the process, if at all possible.

This has me curious now where the Raptor boards are manufactured. It is in the states?

Edit: The boards appear to be produced in Texas according to Phoronix.

There's the 2U heatsinks. I use one in a Blackbird. Works well enough but I would only use it for the 4-core.

You have air moving across it in some capacity though? No issues with throttling or anything?

Could this have had anything to do with why my gif and video work ends up producing rows of vertical artifacts in ffmpeg? It's like the render is there, color-wise, but everything is compressed into these one pixel wide lines.

You might be interested in the package:
Code: [Select]
qemu-system-x86. I'm not sure how one would set it up but I imagine this can be done under qemu/kvm or entirely virt-manager.

It sounds like you want the Condor. IIRC its release is unfortunately on hold.

I actually like the simplicity of the Blackbird as it fits the minimalist design philosophy of having no more than is needed. That said, I was also surprised to find that there was no M.2 port. I've had a bit of a wish list of my own for any prospective Blackbird II:

  • Integrated Displayport rather than (or along with) the HDMI port. I understand that HDMI is more popular in home theater but it is not freedom friendly compared to DP (there are licensing fees for implementing it at the very least).
  • Stronger integrated graphics. The AST2500 is okay, the Talosspace author was even able to get a detailed 3D shooter running on it at something like 10 FPS which is impressive considering what it is. I would love to be able to game on a fully free graphics stack.
  • Suspend-to-RAM funtionality.
  • Shorter boot time.

How do you mean? It's mostly upload the new BMC flash, note the MAC addresses, let it reset itself, reset the MAC addresses to their prior values, and then update the PNOR.

To be fair, it's been a long time since I checked the information. I just recall seeing a lot of WIP discussion at the time and decided to take the conservative approach.

That's a familiar looking CPU fan solution  ;)

If you ever do push it past 10% CPU usage, I would be interested to see if it doesn't shutdown on Blackbird's power contraints.

I'd strongly recommend you were on at least system package 2.00 for DD2.3, yes. It might be glitchy on earlier releases.

It has been largely running fine since installed, aside from that odd 2x cold boot. I am hesitant to upgrade the firmware as there is [still] no really clear procedure and I don't have the spare equipment to remediate if anything goes wrong.

General CPU Discussion / CPU Performance DD2.2 vs DD2.3 (v2)
« on: May 02, 2020, 04:32:31 pm »
I have been unable to find any documented information on the v2 chips beyond the listed features and some vague "5% in some cases" claim on IRC. So I went ahead and got a CP9M31 (v2) to compare. It was a drop in replacement for my Blackbird with the 1.01 firmware. After the system rebooted once with no POST chirp (and a minor heart attack) it proceeded to start up normally. Although the language on the Wiki seems to imply that the new 2.00 firmware is required to run v2 parts?: "PNOR Supports DD2.3 ("v2") CPUs".

Here are some really basic CPU benchmarks with hardinfo:

CPU partCP9M01CP9M31
BlowfishNo data2.04(Lower is better)
CryptoHash854.30945.86(Higher is better)
Fibonacci0.940.94(Lower is better)
N-Queens15.8816.21(Lower is better)
Zlib1.591.54(Higher is better)
FPU FFT1.461.43(Lower is better)
FPU Raytrace2.072.04(Lower is better)

I wouldn't call the test scientific as I did have Gnome system monitor and psensor open in the backgroud for the second run. Interestingly, the part with speculative execution mitigations actually fared worse in N-Queens and Zlib. But it does perform better overall, especially cryptohash. Sorry about the Blowfish stat, my first run didn't grab it and I had already rebuilt my system before I realized it. I will update the table if anybody who has a CP9M01 currently installed wants to run a quick hardinfo benchmark to contribute.

Is this worth adding to the wiki? What would be an appropriate page?

I am not clued in on the subject but wouldn't there theoretically be less work to translate instructions for CG/Wii as they were also powerpc based?

I second that. It would be one thing if any x86 board maker went out, but the loss of Raptor would mean the effective end of something that is quite honestly a rare anomaly in the industry.

I share your enthusiasm and hope that the momentum behind Power does not get killed by this pandemic.
