i965/msaa: Validate Gen7 surface state constraints.

When a Gen7 SURFACE_STATE is configured for MSAA, a number of

gen7_check_surface_setup() which verifies that all of those

i965/msaa: Properly handle sliced layout for Gen7.

Starting in Gen7, there are two possible layouts for MSAA surfaces:

- Interleaved, in which additional samples are accommodated by scaling
  up the width and height of the surface.  This is the only layout
  available in Gen6.  On Gen7 it is used for depth and stencil
  surfaces only.

- Sliced, in which the surface is stored as a 2D array, with array
  slice n containing all pixel data for sample n.  On Gen7 this layout
  is used for color surfaces.

The "Sliced" layout has an additional requirement: it must be used in
ARYSPC_LOD0 mode, which means that the surface doesn't leave any extra
room between array slices for miplevels other than 0.

This patch modifies the surface allocation functions to use the
correct layout when allocating MSAA surfaces in Gen7, and to set the
array offsets properly when using ARYSPC_LOD0 mode.  It also modifies
the code that populates SURFACE_STATE structures to ensure that
ARYSPC_LOD0 mode is selected in the appropriate circumstances.

When considering which components of a variable were killed by an

mask of the assignment.  This worked if the LHS of the assignment was
simple, e.g.:

v.xy = ...; // (assign (xy) (var_ref v) ...)

But it did the wrong thing if the LHS of the assignment involved an

(x):

v[i] = ...; // (assign (x) (deref_array (var_ref v) (var_ref i)) ...)

In general, we can't predict which vector component will be selected

12 years agoglu: fix two Clang warnings

glu: fix two Clang warnings

This patch removes two Clang warnings in GLU:

The first one seems to be an actual bug in mapdesc.cc: Clang complains
that sizeof(dest) will return the size of REAL*[MAXCOORDS], instead of
the intended REAL[MAXCOORDS][MAXCOORDS]. The second one is just
cosmetic because Clang doesn't like extra parentheses.

mesa: reimplement IROUND(), add F_TO_I()

The different implementations of IROUND() behaved differently and in
the case of fistp, depended on the current x86 FPU rounding mode.
This caused some tests like piglit roundmode-pixelstore and
roundmode-getintegerv to fail on 32-bit x86 but pass on 64-bit x86.

Now IROUND() always rounds to the nearest integer (away from zero).
The new F_TO_I function converts a float to an int by whatever means
is fastest.  We'll use this where we're more concerned with performance
and not too worried to how the conversion is done.

svga: fix zero-stride vertex array bug

For zero-stride vertex arrays, the svga driver copies the value into
the constant value and uses that value in the shader.  The recent
gallium-userbuf changes caused a regression in this.  An example
symptom was per-primitive glColor3f() calls getting ignored.

Where we copied the vertex value from the vertex buffer to the
constant buffer we neglected to take into account the
pipe_vertex_buffer::buffer_offset field.  Adding that value to the
source offset fixes the problem.  Actually, it looks like we should
have been doing this all along, but it never was an issue before for
some reason.
