[Mesa-dev] software implementation of vulkan for gsoc/evoc

Hi! I have merged https://cgit.freedesktop.org/~airlied/mesa/log/?h=not-a-vulkan-swrast with mesa-13.0.6 branch. Maybe it will be useful for someone: https://github.com/0lvin/mesa/tree/mesa-13.0.6-vallium (4f83657c02867825ebbd3cc9e407eb989c8f8dee). For build run: ./configure

I'm assuming that control barriers in Vulkan are identical to barriers across a work-group in opencl. I was going to have a work-group be a single OS thread, with the different work-items mapped to SIMD lanes. If we need to have additional scheduling, I have written a javascript compiler that

Re: [Mesa-dev] software implementation of vulkan for gsoc/evoc

by tiled renderer, I meant that I would split the render target into small pieces, then, for each triangle, decide which pieces contains the triangle and add that triangle to per-piece render lists. afterwards, I'd use the constructed render lists and render all the parts of triangles in a piece,

I think vulkan is supposed to be reentrant already. Jacob Lifshay On Feb 10, 2017 3:38 PM, "Roland Mainz" wrote: > On Sat, Feb 11, 2017 at 12:03 AM, Jacob Lifshay > wrote: > > I would like to write a software implementation of Vulkan for

[Mesa-dev] software implementation of vulkan for gsoc/evoc

I would like to write a software implementation of Vulkan for inclusion in mesa3d. I wanted to use a tiled renderer coupled with llvm and either write or use a whole-function-vectorization pass. Would anyone be willing to mentor me for this project? I would probably only need help getting it
