draw: clean up d3d style point clipping

Instead of skipping x/y clipping completely if there's point_tri_clip points
use guard band clipping. This should be easier (previously we could not disable
generating the x/y bits in the clip mask for llvm path, hence requiring custom
clip path), and it also allows us to enable this for tris-as-points more easily
too (this would require custom tri clip filtering too otherwise). Moreover,
some unexpected things could have happen if there's a NaN or just a huge number
in some tri-turned-point, as the driver's rasterizer would need to deal with it
and that might well lead to undefined behavior in typical rasterizers (which
need to convert these numbers to fixed point). Using a guardband should hence
be more robust, while "usually" guaranteeing the same results. (Only "usually"
because unlike hw guardbands draw guardband is always just twice the vp size,
hence small vp but large points could still lead to different results.)
Unfortunately because the clipmask generated is completely unaffected by guard
band clipping, we still need a custom clip stage for points (but not for tris,
as the actual clipping there takes guard band into account).

10 years agoi965: Add a new representation for Broadwell shader instructions.
Kenneth Graunke [Fri, 7 Dec 2012 06:36:26 +0000 (22:36 -0800)]
i965: Add a new representation for Broadwell shader instructions.

Broadwell significantly changes the EU instruction encoding.  Many of
the fields got moved to different bit positions; some even got split
in two.

With so many changes, it was infeasible to continue using struct
brw_instruction.  We needed a new representation.

This new approach is a bit different: rather than a struct, I created a
class that has four DWords, and helper functions that read/write various
bits.  This has several advantages:

1. We can create several different names for the same bits.  For
   example, conditional modifiers, SFID for SEND instructions, and the
   MATH instruction's function opcode are all stored in bits 27:24.

   In each situation, we can use the appropriate setter function:
   set_sfid(), set_math_function(), or set_cond_modifier().  This
   is much easier to follow.

2. Since the fields are expressed using the original 128-bit numbers,
   the code to create the getter/setter functions follows the table in
   the documentation very closely.

To aid in debugging, I've enabled -fkeep-inline-functions when building
gen8_instruction.c.  Otherwise, these functions cannot be called by
gdb, making it insanely difficult to print out anything.

Kenneth Graunke wrote most of this code.  Damien Lespiau ported it to
C99.  Xiang Haihao added media fields.  Zhao Yakui added indirect
addressing support.  Eric Anholt added an assertion to make sure that
values fit in the alloted number of bits.

v2: Update for brw_reg_type_to_hw_type(), which necessitates passing
    brw_context pointers around everywhere.

gallium: add bits for clipping points as tris (d3d-style)

OpenGL does whole-point clipping, that is a large point is either fully
clipped or fully unclipped (the latter means it may extend beyond the
viewport as long as the center is inside the viewport). d3d9 (d3d10 has
no large points) however requires points to be clipped after they are
expanded to a rectangle. (Note some IHVs are known to ignore GL rules at
least with some hw/drivers.)
Hence add a rasterizer bit indicating which way points should be clipped
(some drivers probably will always ignore this), and add the draw interaction
this requires. Drivers wanting to support this and using draw must support
large points on their own as draw doesn't implement vp clipping on the
expanded points (it potentially could but the complexity doesn't seem
warranted), and the driver needs to do viewport scissoring on such points.

It's possible to bind a smaller buffer as a constant buffer, than
what the shader actually uses/requires. This could cause nasty
crashes. This patch adds the architecture to pass the maximum
allowable constant buffer index to the jit to let it make
sure that the constant buffer indices are always within bounds.
The behavior follows the d3d10 spec, which says the overflow
should always return all zeros, and overflow is only defined
as access beyond the size of the currently bound buffer. Accesses
beyond the declared shader constant register size are not
considered an overflow and expected to return garbage but consistent
garbage (we follow the behavior which some wlk tests expect which
