Right.. we started amdkfd as a separate driver to let the compute part move quickly without destabilizing graphics, but probably will integrate them over...

We started development back when "HSA" was called FSA ("Fusion System Architecture") so KFD was the Kernel FSA Driver, or Kernel Fusion...

OK, now that is wierd. If anything I would expect enabling IOMMU to prevent USB from working, not make it work.

My first thought is BIOS...

[bridgman]

Do you mean that enabling IOMMU means you can't use the keyboard mouse, or not enabling it causes the problem ?

We looked at a few IOMMU-related...

The first couple of posts I looked at in the overclockers.ru thread seemed to be people having problems downloading the SDK and trying to run without...

[bridgman]

OK, sounds like you are talking about individual problems then, right ?

I have seen enough published benchmarks on both cards (particularly...

[bridgman]

Last I heard, yes. That said, my recollection was that it only took some fairly small tweaks to the on-demand governor's parameters to fix most of the...

Hi Michael,

User frosth noted in the post above yours that this set of tests was run with ondemand governor rather than the performance governor...

[bridgman]

Get used to it ...

[bridgman]

Please see answer to next question.



Yes, not only outside the company but even inside engineering we have hard NDA walls around...

[bridgman]

Are you just saying that latest mesa, libdrm etc.. are also required ? If so then yes... the kernel driver is only one part of the graphics stack....

[bridgman]

There is definitely something odd going on here. Looking at Michael's previous CPU scaling article...

The document has been updated and so the link has changed (from "...July2017" to "...July2017-1":

Correct - Bristol Ridge / Excavator should be up a row, along with Stoney Ridge.

BTW gsedej the GCN 1.x terminology started fading out after...

[bridgman]

If you look at other recent tests it seems to show a regression in Mesa, although that has not been confirmed. It is possible that performance is actually...

[bridgman]

Another big benefit is that if your application has a large memory footprint it can exceed the coverage of the TLBs (Translation Lookaside Buffers aka...

No, the radeonsi (Mesa) team is completely independent of the Windows team - different people, different ideas.

If you are talking about...

Love those fans. We're trying to figure out where we can put another server lab in the Markham office... I was thinking about stacking them up under my...

Draw Stream Binning Rasterizer is not being used yet in the open drivers yet. Enabling it would be mostly in the amdgpu kernel driver but optimizing performance...

We were using the -PRO driver as an interim consumer solution while the open source stack picked up GL 4.5 support and the devs had a chance to start...
