Re: [Mesa-dev] [PATCH 4/4] nvc0: enable ARB_fragment_layer_viewport
Well, with Roland's fix to the draw module, llvmpipe works with my
tests as well. Is it likely that r600 will work as-is, or do you think
it'll require some fixes? I can try to find someone with the requisite
hw...

Is that cap bit really required? Everybody who can do layered viewports
ought to be able to do this (as it's required by d3d10). Though I can't
say if right now all drivers which support layered viewports can already
do it (llvmpipe can), but it might be trivial to fix those up which can't.

The cap can be removed later if needed.

Well, I think right now the only drivers that support multiple
viewports are llvmpipe, nv50, nvc0, and r600. I can test out llvmpipe
but would need some help for r600. Would love not to have to add the
cap :)

(Of course that should have been layered fbs and multiple viewports,
that short-notation I used there doesn't make much sense...)

Is that cap bit really required? Everybody who can do layered viewports
ought to be able to do this (as it's required by d3d10). Though I can't
say if right now all drivers which support layered viewports can already
do it (llvmpipe can), but it might be trivial to fix those up which can't.
