GPU Compute / Accelerators / GPU & disk encryption?

« on: January 07, 2023, 12:09:01 pm »

I flashed the AMD firmware to the BOOTKERNFW, and can see the Petitboot screen via the AMD GPU! However, when the OS boots, it goes dark for a few seconds, then a cursor appears. Only via the serial display via the BMC web interface am I able to see the prompt to unlock the disk to resume booting. Trying to enter the password on the keyboard doesn't work. Is there a way around this, so I don't need another computer to boot the encrypted disk? I used Debian's auto formatter, so /boot is unencrypted, and LVM has the encrypted swap and root partition. I wouldn't be opposed to having a way to inform Petitboot or BMC of the password somehow.

It was recognised by Petitboot, and able to boot an OS installed on a SATA HDD. I'll keep investigating.

General Discussion / Raptor-provided SATA card issues

« on: December 27, 2022, 09:50:33 am »

I'm using the SATA card provided by Raptor when I bought the Talos II. lsusb identifies it as: SATA controller: Marvell Technology Group Ltd. 88SE9215 PCIe 2.0 x1 4-port SATA 6 Gb/s Controller (rev ff).

Void Linux can see the optical drive as /dev/cdrom which is a link to /dev/sr0. However, I cannot mount a disc, nor can fdisk open it, both with the same error: "no medium found". I was trying some other distros, and after a few warm reboots, the OS no longer sees the optical drive. I attached a hard drive as well, and the distros I tried couldn't see the hard drive at all (though the hard drive works via USB-SATA cable).

dmesg | grep ata has this output:

So I'm wondering, is there a missing firmware file for this? Should I buy another SATA adapter?

General Discussion / Re: AMD RX 6900 XT from Sapphire NITRO

« on: November 11, 2022, 09:03:51 am »

Good news folks, 6900 XT runs fine under 6.1.0rc3!

If you know anyone in Victoria, Australia that might be able to lend me 6800 or 6700 card for few hours, please reach out to me via private message

Working, and with 64k pages too if I remember correctly. This is good news. Does that mean other AMD GPUs also work under 64k pages?

Regarding Void's (and Chimera's) use of 4k pages, how is this used with Qemu & virt-manager? Virt-manager is nice since it creates the XML for libvirt, but I run into the issue where Qemu complains about wanting 64k pages, but not being able to do so on 4k pages.

The Void PPC doc has an entry regarding this: https://docs.voidlinux-ppc.org/configuration/virtualization.html
Which specifies to use -machine pseries,cap-hpt-max-page-size=4096.

How is this specified in the virt-manager or libvirt XML? Looking at https://libvirt.org/drvqemu.html, the closest I could find is using <qemu:commandline>, but that doesn't help, nor does adding the page size flag to machine="pseries".

Operating Systems and Porting / Re: I am looking for a dnetc to count OGR-28 on PPC64LE

« on: October 21, 2022, 08:15:23 am »

Maybe try my Power9 fork? https://github.com/rjzak/dnetc-client-base/tree/power9. I was able to get some things working, still needs some improvements.
If I can get it to a working state, I can see if the maintainer will take it and make a ppc64le release, as per their instruction https://www.distributed.net/Download_clients (very bottom of the page).

Applications and Porting / Re: Interest in Porting Wasmtime & Cranelift

« on: October 08, 2022, 01:18:29 pm »

There's no work on Cranelift yet because I haven't gotten wasm fully working. It passes the tests but some apps inexplicably fail, and I suspect it's not handling int32s correctly which will require a non-trivial refactor.

What aspect of Wasm are you working on? Something in the browser? Another WebAssembly library?

One thing I was thinking of doing with Wasmtime & Cranelift was to start with Wasmtime FIber. It has assembly code for context switching, and of course lacks ppc64le support. I also figured it would be easier for me to get started on, since it's smaller and presumably has unit tests so I can know if I did it right. This is the code for x86_64: https://github.com/bytecodealliance/wasmtime/blob/main/crates/fiber/src/unix/x86_64.rs

I don't see cranelift in there, or anywhere under the chmeeedalf user name.

Cranelift: https://github.com/bytecodealliance/wasmtime/tree/main/cranelift

Specifically, where the ppc64le code would be, if it existed: https://github.com/bytecodealliance/wasmtime/tree/main/cranelift/codegen/meta/src/isa

Applications and Porting / Interest in Porting Wasmtime & Cranelift

« on: October 05, 2022, 11:13:25 am »

I'm interested in getting Wasmtime (WebAssembly Wasi runtime library and program) and Cranelift (JIT used by Wasmtime, others) working on ppc64le. One thing that's interesting is that Power seems to be the only modern platform missing (RISC-V support was merged in recently, and they also support s390x, ARM, and of course, x86_64). As visible in the RISC-V PR, the amount of code required for such an undertaking is massive, and requires extensive knowledge of assembly. I'm interested in doing this work, and have been reading IBM's ISA and ELF ABI documentation, but could use a hand.

It would benefit Firefox, since Cranelift is used by Firefox for WebAssembly JIT compilation, I believe. It would help with some random apps, such as the text editor Lapce, which use Cranelift & Wasmtime for plugins.

Talos II / Re: Damaged motherboard?

« on: October 05, 2022, 10:21:42 am »

I think it's still a pretty big risk to try and use it.
With that big of a solder splash, there could be other smaller and harder to see ones anywhere else on the motherboard.
Or even loose solder balls rolling around waiting to short out some pins.

Turns out, it was fine using the damaged motherboard. I did receive the new one ~2 weeks ago. So all is good!

Talos II / Re: Damaged motherboard?

« on: September 12, 2022, 06:15:34 pm »

It's the third week, and I'm still waiting for the replacement motherboard. It's frustrating that "early next week" has become week three and no response from Support or Sales, and I've emailed them a few times last week and the week before. I also tried reaching out on Twitter last week, and the message is unread yet they're tweeting. It's not fun being ignored waiting for weeks for something which was supposed to be quick, and I'm trying to be patient since I'm sure they've got a million things going on.

In the meantime, what does the community think about using it with just CPU1, since the damage is to a memory slot for CPU 2? It seems that the RAM slot connects only to the CPU, and it not being there wouldn't damage anything if the solder blob is connecting wires that shouldn't be connected. Thoughts?

Talos II / Re: Damaged motherboard?

« on: August 27, 2022, 08:46:29 am »

They are sending a new board early next week, and covering shipping (and return shipping of the solder blob board). They said this hasn't happened before. I do appreciate their quick response (and on a Saturday too!). Also, the paint on the chips indicates the version of the firmware at shipping, which is neat.

Talos II / Damaged motherboard?

« on: August 26, 2022, 04:17:52 pm »

I ordered my first Raptor product, the Talos II (+CPUs bundle), and it arrived today! However, after unpacking, I had some concerns.

In the attachments, there's an image of what looks like spilled solder on a memory slot, and a weird orange rust-looking dot on a chip which is not present in the high-resolution image from the Wiki. Yet, there was a note in the package showing that tests passed. How worried should I be? I'm afraid the solder spill could short something out, and I spent too much money (personal money for personal computer) on this so I'm going to nit-pick.

I did email support, waiting to hear back.

After checking the docs, the Talos & Blackbird boards use the 20-pin TPM. So maybe these would work:

* https://a.co/d/91veo25 (Generic brand? not too comfortable with that, unknown chip)
* https://a.co/d/4QA7amk (looks exactly like the one above, same marketing images, not a well-known brand, unknown chip)
* https://a.co/d/etHR62A (SuperMicro, Infineon chip)
* https://a.co/d/bD90lpO (Another no-name brand, unknown chip)
