Got it (merged in), thanks.
But now I need some sleep.
Have to drive my wife to the hospital in a few hours.
No, not hyperacute.

If I only had some big triangle apps...;-)

Dieter, you need final LLVM 8.0.

GREAT stuff, Marek!
But sadly some crashes.
Is my LLVM git version to old?
7. Jan 2019 (short before 8.0 cut)
LLVM (http://llvm.org/):
LLVM version 8.0.0svn
Optimized build.

Please have a look at my post @Phoronix:

Hi,
This patch series uses async compute to do primitive culling
before
the vertex shader. It significantly improves performance for
applications
that use a lot of geometry that is invisible because primitives
don't
intersect sample points or there are a lot of back faces, etc.
It passes 99.9999% of all tests (GL CTS, dEQP, piglit) and is
100%
stable.
It supports all chips all the way from Sea Islands to Radeon
VII.
As you can see in the results marked (ENABLED) in the picture
below,
it destroys our competition (The GeForce results are from a
Phoronix
article from 2017, the latest ones I could find):
Benchmark: ParaView - Many Spheres - 2560x1440
https://people.freedesktop.org/~mareko/prim-discard-cs-results.png
The last patch describes the implementation and functional
limitations
if you can find the huge code comment, so I'm not gonna do that
here.
I decided to enable this optimization on all Pro graphics cards.
The reason is that I haven't had time to benchmark games.
This decision may be changed based on community feedback, etc.
People using the Pro graphics cards can disable this by setting
AMD_DEBUG=nopd, and people using consumer graphics cards can
enable
this by setting AMD_DEBUG=pd. So you always have a choice.
Eventually we might also enable this on consumer graphics cards
for
those
games that benefit. It might decrease performance if there is
not
enough
invisible geometry.
Branch:
https://cgit.freedesktop.org/~mareko/mesa/log/?h=prim-discard-cs
Please review.
Thanks,
Marek
