Firmware / Re: Firmware 2.10 for Talos-II and Blackbird available

« on: March 23, 2024, 09:52:03 pm »

what is the linux kernel version of firmware 2.10? Some cards are known to be buggy with old kernel, please refer to https://wiki.raptorcs.com/wiki/POWER9_Hardware_Compatibility_List/PCIe_Devices for compatability

6.6 I think. The new firmware is up and running on my evaluation system but I'm not loading firmwares as r34per is trying to do.

I've heard the same too, that it's had it since Vega -- but that it needs PSP or ME on the CPU side too to be effective.

Do you know where I might find literature on this? In what way does it attempt to link to the CPU PSP?

It seems to have fallen through with no change brought about by any of the dialogue.

GPU Compute / Accelerators / AMD flirting with open sourcing GPU firmware

« on: March 07, 2024, 10:30:07 am »

A vendor has been deliberating with AMD about opening up GPU firmware. But possibly only for the 6x7900XTX model? And possibly only the scheduler and memory management bits? But the optimist in me wants to believe this could lead to the end of the nonfree firmware dilemma in choosing to install an add-in graphics card.

Call went pretty well.

We are gating the commitment to 6x7900XTX on a public release of a roadmap to get the firmware open source. (and obviously the MLPerf training bug being fixed)

We aren't open source purists, it doesn't matter to us if the HDCP stuff is open for example. But we need the scheduler and the memory hierarchy management to be open. This is what it takes to push the performance of neural networks.

The Groq 500 T/s mixtral demo should be possible on a tinybox, but it requires god tier software and deep integration with the scheduler.

We also advised that the build process for amdgpu-dkms should be more open. While the driver itself is open, we haven't found it easy to rebuild and install. Easy REPL cycle is a key driver for community open source. We want the firmware to be easy to rebuild and install also.

Should have a go or no go decision by the end of next week. Confidence: 70%

Have a call with AMD tomorrow. Will they open source the MES?

Debian Bookworm ffmpeg 5.1.4-0+deb12u1 introduces an issue where default h264 encoding for mp4 videos creates artifacting. Green patches on frame-by-frame changes.

It can be worked around by manually specifying a different video codec.

Code: [Select]

ffmpeg -i sample.mp4 -vcodec mpeg2video output.mp4

I have read recently that newer AMD GPUs include a version of PSP. Can this be verified? It is everything dating back to Polaris?

Firmware / Re: Adventures in reverse engineering broadcom nic firmware

« on: January 03, 2024, 07:22:04 pm »

The presence of an RSA signature, I venture a guess may be present as there might be other Broadcom products which do check the signature. And Broadcom's internal policy may simply be to sign everything just so that there is uniformity across development.

It is simple to contribute to right now. I don't think we intended for so very many games to actually work that the list would outgrow a simple column. Maybe it can be split it up into:

Native builds
Engine re-implementations
Emulators

Blackbird / Re: OpenBMC reporting critical error Proc.FSI.Error.MasterDetectionFailure

« on: January 03, 2024, 05:58:34 pm »

These events have also been showing in the 'Server Health' section of my BMC web panel. Just four marked from 2020, and two more recent from December 2023.

Code: [Select]

org.Open_power.Proc.FSI.Error.MasterDetectionFailure
CALLOUT_DEVICE_PATH=/sys/devices/platform/gpio-fsi/fsi0/slave@00:00/raw CALLOUT_ERRNO=0_PID=4612
My system has been fine, other than occasionally booting without properly setting RTC time to the host (same issue that ClassicHasClass has been seeing?)

If this is power outage related, that would make sense since, through 2020, I unknowingly had my Blackbird on a bad uninterruptible power supply. Then later had it in a location prone to outages before replacing the UPS.

If these logs are nothing critical, they should be safe to clear from the log?

Operating Systems and Porting / Re: Debian 12 status?

« on: December 13, 2023, 09:15:23 pm »

Have another computer handy because Debian still have not readded the ast module for initramfs to their installation images.

Have a look at the wiki. You'll need to set console=hvc0 to grub cmd line and conduct the TUI installer from another machine through obmc-console-client. Huge PITA, but worth it to have Debian IMO.

General OpenPOWER Discussion / Re: POWER11 on the horizon?

« on: November 27, 2023, 08:11:52 pm »

If anything I'm most interested in is IBM returning to its core open source design, so that it has a Power 11 processor that's exactly as open as a Power 8 or Power 9, I'm not going to buy Power CPUs. that they are not IBM because their technology is the best ever for their processors and I don't think that any other company, no matter how good, can reach their level and therefore I don't intend to change companies for these microprocessors. IBM creates it and IBM must produce it or have it produced by one of its direct partners to be the best, this at least is my humble opinion and then obviously it is debatable by anyone.

I've learned in life not to get hung up on vendor brands. Especially in the computing space, it's all about the design and how it's implemented.

Here is the website of Solid Silicon: https://www.solidsilicon.com/

No matter how I try to view the site, it only loads a blank white canvas (Or black canvas, with CSS but no javascript). There is a vimeo link supplied to a scene of smoke rolling over mountains. I assume they attempt to use this for an animated backdrop?

It hasn't been picked up by web archive and other archivers also just grab a blank page. Has anybody been able to view their page?

General CPU Discussion / Re: Power10 announcement from Raptor soon?

« on: October 23, 2023, 07:00:17 pm »

Raptor said minimum size for Power10 would be ATX. I'm fine with that.
He mentioned also LibreSOC as a SBC. Availability 2024.

Perfect for a revival of the Condor. Not my cup of tea, I'm a small form factor kind of guy, but I suspect a standard ATX would do well with the DIY market.

In my opinion it is more convenient to wait for Power 11, at least as far as I'm concerned, at the moment I don't need to advance so I'm perfect with Power 9

I find that performance is still adequate for my needs. At this point, an upgrade would just be to get shorter IPL and boot times and maybe suspend to RAM.

and then apparently there is more possibility that 11 will be completely open as Raptor wants. The only thing I hope is that at least after all the money spent on research and development for 2 nanometers, they can use it with Power 11!

I'm prepared to ride out Power9 for years if it's successor are never properly reopened.
