Applications and Porting / Re: [DEV] An attempt to package chromium for ppc64le in the official Fedora DNF repo

« Last post by MauryG5 on March 17, 2024, 08:55:35 am »

Well this is excellent news, up to now in fact on Power, Chromium is only found on Debian and it works really very well.  So it's very good to see it again on Fedora after a long time.

Applications and Porting / Re: MAME for Power

I understand it would take a developer who knows how to write the code apart from you and who can dedicate a bit and at the moment there isn't unfortunately... I hope in the future at least

Sorry, it just hasn't been a priority for me yet. I have relatively low needs from MAME, just a couple very old systems that don't require very sophisticated emulation.

It's been a long time since the last post in this thread, does anyone have any news regarding any improvements in the performance of MAME on Power? Classic Has had said he wanted to work on it but to date he hasn't given any more news on the matter...

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

« Last post by Borley 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?

User Zone / Re: Rough edges and how I work around them (or not)

« Last post by Hasturtium on March 05, 2024, 01:11:07 pm »

It seems like video encoding on Power9 has been a rough edge on the platform since the beginning... I know the VP9 encoder was getting some decent ppc64le optimizations several years back; did those ever get merged into trunk? Short of using a hardware-assisted encoder I don't even know what my options are that don't require encoding to 480p.

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

GPU Compute / Accelerators / Re: Radeon RDNA3 support?

« Last post by MPC7500 on March 05, 2024, 08:58:29 am »

Indeed. Unfortunately, only 7600s are currently available as dual slot cards. Starts at 280€ (Germany).
Then there are the Pro cards (W7500 - W7800) as single and dual slot. Start at approx. 450€.
However, these are not any faster than the consumer cards.

I personally can tell you that if you have a Blackbird and you have to use both PCI express slots, you must necessarily use up to a maximum of 2 slots, otherwise you won't be able to use the second slot.  Unfortunately, the new Radeons are almost all 2.5 and therefore you can't use them.  That's why I was thinking that if there was a possibility, get a 7700 pro that uses 2 slots, even if it costs a lot more unfortunately being pro.  I use the 8 PIN slot for the sound card so I'm one of those who necessarily needs to use 2-slot graphics cards and no more.
