Intel's ANV Vulkan Driver Now Supports Tessellation Shaders

[edoantonioco]

It's really easy actually - you don't need to install anything at all.

$ git clone git://anongit.freedesktop.org/mesa/mesa
$ cd mesa
$ CFLAGS='-g -fno-omit-frame-pointer' CXXFLAGS='-g -fno-omit-frame-pointer' ./autogen.sh --with-egl-platforms=x11,drm,wayland --with-dri-drivers=i965 --with-gallium-drivers="" --enable-debug --with-vulkan-drivers=intel --sysconfdir=/etc
$ make -j5

Then:
$ export VK_ICD_FILENAMES="$HOME/mesa/src/intel/vulkan/dev_icd.json" # or wherever you put yoru mesa checkout...
$ <run your app>

If you want to use it for GL as well, then (again, adjusting paths)
$ export LIBGL_DRIVERS_PATH="$HOME/mesa/lib"
$ export LD_LIBRARY_PATH="$LD_LIBRARY_PATH:$HOME/mesa/lib"

Very cool

Wow, this was more than helpful!

Didn't know you can run a local Mesa version that way.

Thanks again!

And indeed, vkQuake now starts.
I'll test it tomorrow. For now, all I can see is the menu flickering.
But hey - this is very promising.

Edit: It's only the menu flickering. The game seems to work flawless. \o/

Let's see if Arcane Dimensions runs properly.

That new single-player mod is nothing short of awesome

I see. Thank you.
Will be waiting for Mesa 17 then.
Not sure how difficult it is to compile Mesa from git on Fedora without messing up my system.

The SPIR-V stuff should be reusable with a few minor modifications. I suspect it should be pretty easy to hook up.

I'm not sure - Jason would be more likely to know. I know that vkQuake uses input attachments, and IIRC those weren't implemented in Mesa 13. They are in master. So it's worth a try...

How far is Tessellation support in radv off now that anv has it? Can anything be reused from the frontend?

Yep, it works great on Haswell. I haven't actually tried Ivybridge, but it should all be there.

Do you know if vkQuake should now run on Haswell or what is missing?

(You can run it with the freely available shareware episode if you want to test it)

With Mesa 13.0.3 on Fedora 25 it always SEGFAULTs:

I believe so, didn't see any conditional statements regarding to exposing tesselationShader.

[Michael]

does this apply for haswell too?
