edf066f385 mesa: Generate correct error code in glDrawBuffers()
OpenGL 3.3 spec expects GL_INVALID_OPERATION:
 "For both the default framebuffer and framebuffer objects, the
  constants FRONT, BACK, LEFT, RIGHT, and FRONT AND BACK are not
  valid in the bufs array passed to DrawBuffers, and will result
  in the error INVALID OPERATION."

But OpenGL 4.0 spec changed the error code to GL_INVALID_ENUM:
 "For both the default framebuffer and framebuffer objects, the
  constants FRONT, BACK, LEFT, RIGHT, and FRONT_AND_BACK are not
  valid in the bufs array passed to DrawBuffers, and will result
  in the error INVALID_ENUM."

This patch changes the behaviour to match OpenGL 4.0 spec
Fixes Khronos OpenGL CTS draw_buffers_api.test.

V2: Update the comment in code.

559d9b894e i965: Ignore 'centroid' interpolation qualifier in case of persample shading
This patch handles the use of 'centroid' qualifier with 'in' variables
in a fragment shader when persample shading is enabled. Per sample
shading for the whole fragment shader can be enabled by:
glEnable(GL_SAMPLE_SHADING) or using {gl_SamplePosition, gl_SampleID}
builtin variables in fragment shader. Explaining it below in more
detail.

/* Enable sample shading using OpenGL API */
glEnable(GL_SAMPLE_SHADING);
glMinSampleShading(1.0);

Example fragment shader:
in vec4 a;
centroid in vec4 b;
main()
{
  ...
}

Variable 'a' will be interpolated at sample location. But, what
interpolation should we use for variable 'b' ?

ARB_sample_shading recommends interpolation at sample position for
all the variables. GLSL 400 (and earlier) spec says that:

"When an interpolation qualifier is used, it overrides settings
established through the OpenGL API."
But, this text got deleted in later versions of GLSL.

NVIDIA's and AMD's proprietary linux drivers (at OpenGL 4.3)
interpolates at sample position. This convinces me to use
the similar approach on intel hardware.

765e3d373b i965: Use sample barycentric coordinates with per sample shading
Current implementation of arb_sample_shading doesn't set 'Barycentric
Interpolation Mode' correctly. We use pixel barycentric coordinates
for per sample shading. Instead we should select perspective sample
or non-perspective sample barycentric coordinates.

It also enables using sample barycentric coordinates in case of a
fragment shader variable declared with 'sample' qualifier.
e.g. sample in vec4 pos;

A piglit test to verify the implementation has been posted on piglit
mailing list for review.

V2: Do not interpolate all the 'in' variables at sample position
    if fragment shader uses 'sample' qualifier with one of them.
    For example we have a fragment shader:
    #version 330
    #extension ARB_gpu_shader5: require
    sample in vec4 a;
    in vec4 b;
    main()
    {
      ...
    }

    Only 'a' should be sampled at sample location, not 'b'.

f7848574b3 i965/gen6/blorp: Emit more flushes to workaround hangs
This is a squash of three related cherry-picks from master.

[PATCH 1/3]

  i965/gen6/blorp: Set need_workaround_flush immediately after primitive

  This patch makes the workaround code in gen6 blorp follow the pattern
  established in the regular draw path. It shouldn't result in any
  behavioral change.

  On gen6, there are two places where we emit 3D_CMD_PRIM: brw_emit_prim()
  and gen6_blorp_emit_primitive().  brw_emit_prim() sets
  need_workaround_flush immediately after emitting the primitive, but
  blorp does not. Blorp sets need_workaround_flush at the bottom of
  brw_blorp_exec().

  This patch moves the need_workaround_flush from brw_blorp_exec() to
  gen6_blorp_emit_primitive().  There is no need to set
  need_workaround_flush in gen7_blorp_emit_primitive() because the
  workaround applies only to gen6.

[PATCH 2/3]

  i965/gen6/blorp: Set need_workaround_flush at top of blorp

  Unconditionally set brw->need_workaround_flush at the top of gen6 blorp
  state emission.

  The art of emitting workaround flushes on Sandybridge is mysterious and
  not fully understood. Ken and I believe that
  intel_emit_post_sync_nonzero_flush() may be required when switching from
  regular drawing to blorp.  This is an extra safety measure to prevent
  undiscovered difficult-to-diagnose gpu hangs.

  I verified that on ChromeOS, pre-patch, need_workaround_flush was not
  set at the top of blorp, as Paul expected. To verify, I inserted the
  following debug code at the top of gen6_blorp_exec(), restarted the ui,
  and inspected the logs in /var/log/ui. The abort gets triggered so early
  that the browser never appears on the display.

      static void
      gen6_blorp_exec(...)
      {
          if (!brw->need_workaround_flush) {
              fprintf(stderr, "chadv: %s:%d\n", __FILE__, __LINE__);
              abort();
          }
          ...

df62691a02 draw: fix incorrect vertex size computation in LLVM drawing code
We were calling draw_total_vs_outputs() too early.  The call to
draw_pt_emit_prepare() could result in the vertex size changing.
So call draw_total_vs_outputs() after draw_pt_emit_prepare().

This fix would seem to be needed for the non-LLVM code as well,
but it's not obvious.  Instead, I added an assertion there to
try to catch this problem if it were to occur there.

fe2678accd glsl: Fix chained assignments of vector channels.
Simple shaders such as:

    void splat(vec2 v, float f) {
        v[0] = v[1] = f;
    }

failed to compile with the following error:
error: value of type vec2 cannot be assigned to variable of type float

First, we would process v[1] = f, and transform:
LHS: (expression float vector_extract (var_ref v) (constant int (1)))
RHS: (var_ref f)
into:
LHS: (var_ref v)
RHS: (expression vec2 vector_insert (var_ref v) (constant int (1))
                 (var_ref f))

Note that the LHS type is now vec2, not a float.  This is surprising,
but not the real problem.

After emitting assignments, this ultimately becomes:
(declare (temporary) vec2 assignment_tmp)
(assign (xy)
  (var_ref assignment_tmp)
  (expression vec2 vector_insert (var_ref v) (constant int (1))
              (var_ref f)))
  (assign (xy) (var_ref v) (var_ref assignment_tmp))

We would then return (var_ref assignment_tmp) as the rvalue, which has
the wrong type---it should be float, but is instead a vec2.

To fix this, we simply return (vector_extract (var_ref assignment_temp)
<the appropriate channel>) to pull out the desired float value.

Fixes Piglit's chained-assignment-with-vector-constant-index.vert and
chained-assignment-with-vector-dynamic-index.vert tests.

that it could ask the driver to compress with some expectation of
quality.  The GL_ARB_texture_compression spec calls this "suitable for
general-purpose usage."  As noted above, this means
GL_COMPRESSED_RGBA_S3TC_DXT1_EXT is not included in the list.

In OpenGL ES, the driver never performs compression.
GL_NUM_COMPRESSED_TEXTURE_FORMATS and GL_COMPRESSED_TEXTURE_FORMATS give
the application a list of formats that the driver can receive from the
application.  It is the *complete* list of formats.  The
GL_EXT_texture_compression_s3tc spec says:

    "New State for OpenGL ES 2.0.25 and 3.0.2 Specifications

        The queries for NUM_COMPRESSED_TEXTURE_FORMATS and
        COMPRESSED_TEXTURE_FORMATS include COMPRESSED_RGB_S3TC_DXT1_EXT,
        COMPRESSED_RGBA_S3TC_DXT1_EXT, COMPRESSED_RGBA_S3TC_DXT3_EXT,
        and COMPRESSED_RGBA_S3TC_DXT5_EXT."

Note that the addition is only to the OpenGL ES specification!

45f0736aa5 st/mesa: use signed temporary variable to store _ColorDrawBufferIndexes
The temporary variable used to store _ColorDrawBufferIndexes must be
signed (GLint), otherwise the following conditional will be incorrectly
evaluated. Leading to crashes in the driver/mesa or accessing/writing
to arbitrary memory location. The bug dates back to 2009.

dbc0ae1079 Use AC_PATH_TOOL instead of AC_PATH_PROG for llvm-config.
This should help with cross-compiling and multilib when $CHOST-specific
llvm-config is expected rather than build host default one.

It will help us a bit in Gentoo where we've started using
i686-pc-linux-gnu-llvm-config for 32-bit multilib LLVM.

9ca4c8f6a2 i965: Ensure that all necessary state is re-emitted if we run out of aperture.
Prior to this patch, if we ran out of aperture space during
brw_try_draw_prims(), we would rewind the batch buffer pointer
(potentially throwing some state that may have been emitted by
brw_upload_state()), flush the batch, and then try again.  However, we
wouldn't reset the dirty bits to the state they had before the call to
brw_upload_state().  As a result, when we tried again, there was a
danger that we wouldn't re-emit all the necessary state.  (Note: prior
to the introduction of hardware contexts, this wasn't a problem
because flushing the batch forced all state to be re-emitted).

This patch fixes the problem by leaving the dirty bits set at the end
of brw_upload_state(); we only clear them after we have determined
that we don't need to rewind the batch buffer.

3a6271890c i965: Don't do the temporary-and-blit-copy for INVALIDATE_RANGE maps.
We definitely want to fall through to the unsynchronized map case, instead
of wasting bandwidth on a copy.  Prevents a -43.2407% +/- 1.06113% (n=49)
performance regression on aa10perf when teaching glamor to provide the
GL_INVALIDATE_RANGE_BIT information.

This is a performance fix, which I usually wouldn't cherry-pick to stable.
But this was really was just a bug in the code, its presence would
discourage developers from giving us the best information they can, and I
think we've got fairly high confidence in the unsynchronized map path
already.

c24489b0ef i965: fold offset into coord for textureOffset(gsampler2DRect)
The hardware is broken with nonzero texel offsets and unnormalized
coordinates; instead of doing correct offsetting, we get garbage.

This just extends the existing workaround for ir_txf and
ir_tg4+gsampler2DRect to also consider ir_tex+gsampler2DRect.

Fixes broken rendering in 'tesseract' when 'mesa_texrectoffset_bug' is
not enabled; also fixes the new piglit test
'tests/spec/glsl-1.30/execution/fs-textureOffset-Rect'.

Has been broken ~forever; suggesting including this in only 10.0 because
the lowering pass doesn't exist in 9.2 or earlier so would require quite
a different patch.
