General CPU Discussion / Re: Ultravisor state and/or FlexVer as a substitute for confidential/trustworthy rem

« on: August 21, 2022, 07:01:28 pm »

According to IBM’s paper, the Ultravisor uses a TPM and IBM recommends Nuvoton. https://dl.acm.org/doi/10.1145/3447786.3456243

I also noticed there isn’t anything on the Forum or Wiki about supported TPMs. Sorry if this is a dumb question, as I’ve never used them before, but is there any reason as to why this one wouldn’t work?

GPU Compute / Accelerators / Re: Which GPU would *you* choose?

« on: August 02, 2022, 08:04:17 pm »

Here you can find a good overview:
https://wiki.raptorcs.com/wiki/POWER9_Hardware_Compatibility_List/PCIe_Devices#AMD

How up-to-date is the GPU list? A few of the items have wording like "May need at least linux 4.16", or "A compatibility mode is expected to be included in Linux 5.4 and above that will resolve this issue. ", or requires kernel patches from 3 years ago. I'm considering a Talos II build, but am worried about the GPU issue. Is the 580 still the best working non-pro Radeon? I'm also not familiar with AMD cards, I've always been an Nvidia person, but won't be using one for the Talos due to the many obvious reasons... I'm assuming Void Linux is the best way to go to side-step the 64k kernel page issue, and that this issue is still a problem today?

So for the sake of clarify, the "v2" POWER9 chips do support the Ultravisor, correct?

The Wiki says POWER9 2.3 does support Ultravisor: https://wiki.raptorcs.com/wiki/POWER9#Steppings
And the Wiki says that Ultravisor does not exist in POWER9: https://wiki.raptorcs.com/wiki/Power_ISA/Privilege_States

I also ask because I'm working on a project (Enarx) which runs workloads in trusted execution environments, such as Intel SGX. I'd like to support POWER9's Ultravisor/PEF if it's available on a Talos II system, and functional (and hopefully documented enough to figure out!).

I've been able to connect, set an IP, install needed packages. Thank you for the help!

@SiteAdmin is Raptor, or at least someone on their technical staff.

It looks like you're doing this through the OpenBMC web interface?

This is all done via the OpenBMC web interface. That's all that was provided.

Did you set the date to a correct value? Otherwise Ethernet will not work.

That's the first I've ever heard of that...

Talos II / Re: Advice for installing OS via BMC?

« on: February 05, 2021, 08:36:59 am »

I went to another part of the BMC, and back to KVM, and the login prompt for Void appeared! All looks good and straight forward, except that it seems I can't configure the network. The first interface doesn't work with DHCP, and it seems the second interface isn't connected. This is a test machine provided by Raptor, and they haven't responded to my email, which is why I came to the forum.

What's annoying is that the KVM interface periodically blanks out, and the Refresh button doesn't work. I have to go to some other page, like Sensors, then back to KVM to see the screen. I have Void installed, but since  DHCP and network information isn't provided, I'm at a point where I can't continue my evaluation.

Screenshot of the serial console is attached, it looks like its running some graphical interface but the KVM functionality of the BMC isn't catching it (it's blank).

Talos II / Advice for installing OS via BMC?

« on: February 01, 2021, 05:18:54 pm »

I'm new to Raptor systems, and I have been granted remote access to a Talos II machine. I need to install the OS, but haven't been successful. So far, I tried the Ubuntu 20.10 PPC64LE and Debian PPC64LE full CD installer over the virtual media, and from the serial connection, I can see the kernel crashes.  I have been able to get to the menus in the serial connection for the Debian network installer, but I don't know the network settings. Is it ok to reuse the BMC IP? Is it a safe assumption that the BMC shares the first Ethernet connection port? Next I'm trying Void Linux to see if that's an improvement.
