Third Party CPU Discussion / Re: Why haven't we seen boards with Power9 / MicroWatt?

« on: August 28, 2024, 08:31:52 pm »

If RCS sought to develop and sell RISC-V systems, I would have no reservations about buying any. It's not that I have any particular loyalty to PowerPC or anything. It just happened to be the most mature, complete and performant solution available.

Applications and Porting / Re: How to build Barony Game

« on: August 07, 2024, 12:19:31 pm »

Recent releases appear to have dropped OpenAL audio, requiring audio to be disabled in compile options before Barony can be built successfully.

Which means that recent Barony (with all the fancy lighting improvements) cannot be played on PowerPC linux with audio, until this has been resolved.

Operating Systems and Porting / Re: Debian security standards, deflecting questions about SSH2 issue

« on: July 05, 2024, 12:28:55 pm »

It looks like I have some evening reading to catch up on.

https://danielpocock.com/integrity-fail-debian-social-contract/

As I age, my perception skews further toward "humans are flawed beings", and no amount of rule making or societal structuring will ever eliminate exploitative behavior. And in software projects, the more humans (flawed beings) are involved, the more exploitative activity will occur. None of this is to excuse such behavior.

I can think of Maone, author behind NoScript, having dubious history but still being a net positive in the world of adblocking and open source software.

Andreas Tille - Can it be inferred that his intentions with his time as project leader are malicious? What kind of negative changes, impacting Debian security, would one anticipate being made during this time?

Blackbird / Re: Availability of P9 hardware post-ISA 3.1 HW launch

« on: June 29, 2024, 10:32:43 am »

FWIW, I do not plan to sell my current RCS boards once the new ones are available. They will become relegated to the roles currently filled by some older x86 systems that I have.

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.

GPU Compute / Accelerators / Re: Radeon RDNA3 support?

« on: March 23, 2024, 09:45:45 pm »

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
Hangover/Box64

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?
