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...

[bridgman]

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

If you are talking about...

[bridgman]

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...

[bridgman]

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...

[bridgman]

I think CrystalGamma's question was not "prove that a faster core will compile faster" (which I agree needs no citation) but "prove that...

[bridgman]

I think so. Getting started earlier allowed us to have drivers upstream before launch despite the size of the work required, and that in turn put us in...

[bridgman]

Don't think it was me. Maybe agd5f ?...

[bridgman]

Yes, that's where the idea for "the display code formerly known as DAL/DC" came from... once the code is structured in an acceptable way nobody...

[bridgman]

The differences in the userspace driver were smaller than the architecture breaks at r600 and GCN, but the differences in the kernel driver were bigger...

[bridgman]

The GCNx nomenclature is something the media made up and we try to align with occasionally. Something like:

GCN1 - GFX6
GCN2 - GFX7...

[bridgman]

AFAIK Michael's initial tests of the all-open driver on Vega included large page support, so unless you were running Vega with older upstream previously...
