Mesa provides the flexibility of building without the
need to have libdrm present on the system. The situation
has regressed with the recent commit

    loader: introduce the loader util lib

By isolating libdrm code by #ifndef __NOT_HAVE_DRM_H we
can have libdrm-less builds on across all build systems.

This patch converts Android's _EGL_NO_DRM to __NOT_HAVE_DRM_H
to provide consistency with the other cases within mesa, allows
compilation of libloader on libdrm-less scons and conditionally

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.

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.

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
