i965/fs: Reject copy propagation into SEL if not min/max.

2016-12-24T13:03:53+00:00

We shouldn't ever see a SEL with conditional mod other than GE (for max)
or L (for min), but we might see one with predication and no conditional
mod.

i965/mt: Disable aux surfaces after making miptree shareable

2016-12-14T19:31:30+00:00

The entire goal of intel_miptree_make_shareable() is to permanently
disable the miptree's aux surfaces. So set
intel_mipmap_tree:disable_aux_buffers after the function's done with
discarding down the aux surfaces.

i965: Allocate at least some URB space even when max_vertices = 0.

2016-12-14T19:03:11+00:00

Allocating zero URB space is a really bad idea.  The hardware has to
give threads a handle to their URB space, and threads have to use that
to terminate the thread.  Having it be an empty region just breaks a
lot of assumptions.  Hence, why we asserted that it isn't possible.

Unfortunately, it /is/ possible prior to Gen8, if max_vertices = 0.
In theory a geometry shader could do SSBO/image access and maybe
still accomplish something.  In reality, this is tripped up by
conformance tests.

Gen8+ already avoids this problem by placing the vertex count DWord
in the URB entry header.  This fixes things on earlier generations.

i965: Fix GS push inputs with enhanced layouts.

2016-11-24T16:34:41+00:00

We weren't taking first_component into account when handling GS push
inputs.  We hardly ever push GS inputs, so this was not caught by
existing tests.  When I started using component qualifiers for the
gl_ClipDistance arrays, glsl-1.50-transform-feedback-type-and-size
started catching this.
