acf3d2afab configure: check once for DRI3 dependencies
Currently we are having the XCB_DRI3 dependencies duplicated,
partially.

Just do a once-off check and add all of the respective CFLAGS/LIBS
where needed.

As a nice side effect this helps us solve a couple of FIXMEs.

DRI3 is not a thing w/o X11 so disable it in such cases.

56458cb168 anv/formats: Update the three-channel BC1 mappings
The procedure for decompressing an opaque BC1 Vulkan format is dependant on the
comparison of two colors stored in the first 32 bits of the compressed block.
Here's the specified OpenGL (and Vulkan) behavior for reference:

   The RGB color for a texel at location (x,y) in the block is given by:

      RGB0,              if color0 > color1 and code(x,y) == 0
      RGB1,              if color0 > color1 and code(x,y) == 1
      (2*RGB0+RGB1)/3,   if color0 > color1 and code(x,y) == 2
      (RGB0+2*RGB1)/3,   if color0 > color1 and code(x,y) == 3

      RGB0,              if color0 <= color1 and code(x,y) == 0
      RGB1,              if color0 <= color1 and code(x,y) == 1
      (RGB0+RGB1)/2,     if color0 <= color1 and code(x,y) == 2
      BLACK,             if color0 <= color1 and code(x,y) == 3

The sampling operation performed on an opaque DXT1 Intel format essentially
hard-codes the comparison result of the two colors as color0 > color1. This
means that the behavior is incompatible with OpenGL and Vulkan. This is stated
in the SKL PRM, Vol 5: Memory Views:

   Opaque Textures (DXT1_RGB)
      Texture format DXT1_RGB is identical to DXT1, with the exception that the
      One-bit Alpha encoding is removed. Color 0 and Color 1 are not compared, and
      the resulting texel color is derived strictly from the Opaque Color Encoding.
      The alpha channel defaults to 1.0.

      Programming Note
      Context: Opaque Textures (DXT1_RGB)
      The behavior of this format is not compliant with the OGL spec.

The opaque and non-opaque BC1 Vulkan formats are specified to be decoded in
exactly the same way except the BLACK value must have a transparent alpha
channel in the latter. Use the four-channel BC1 Intel formats with the alpha
set to 1 to provide the behavior required by the spec.

v2 (Kenneth Graunke):
- Provide a more detailed commit message.

c499faebd7 anv: Add an option to abort on device loss
This is mostly for running in our CI system to prevent dEQP from
continuing on to the next test if we get a GPU hang.  As it currently
stands, dEQP uses the same VkDevice for almost all tests and if one of
the tests hangs, we set the anv_device::device_lost flag and report
VK_ERROR_DEVICE_LOST for all queue operations from that point forward
without sending anything to the GPU.  dEQP will happily continue trying
to run tests and reporting failures until it eventually gets crash that
forces the test runner to start over.  This circumvents the problem by
just aborting the process if we ever get a GPU hang.  Since this is not
the recommended behavior most of the time, we hide it behind an
environment variable.

2322ddf548 anv: fix multiview for clear commands
According to the VK_KHX_multiview spec:

"Multiview causes all drawing and clear commands in the subpass to
behave as if they were broadcast to each view, where each view is
represented by one layer of the framebuffer attachments."

This adds support for multiview clears, which were missing in the
initial implementation.

e69e5c7006 i965/vec4: load dvec3/4 uniforms first in the push constant buffer
Reorder the uniforms to load first the dvec4-aligned variables in the
push constant buffer and then push the vec4-aligned ones. It takes
into account that the relocated uniforms should be aligned to their
channel size.

This fixes a bug were the dvec3/4 might be loaded one part on a GRF and
the rest in next GRF, so the region parameters to read that could break
the HW rules.

v2:
- Fix broken logic.
- Add a comment to explain what should be needed to optimise the usage
  of the push constant buffer slots, as this patch does not pack the
  uniforms.

v3:
- Implemented the push constant buffer usage optimization.

8aa6ada838 i965/vec4: fix swizzle and writemask when loading an uniform with constant offset
It was setting XYWZ swizzle and writemask to all uniforms, no matter if they
were a vector or scalar, so this can lead to problems when loading them
to the push constant buffer.

Moreover, 'shift' calculation was designed to calculate the offset in
DWORDS, but it doesn't take into account DFs, so the calculated swizzle
for the later ones was wrong.

The indirect case is not changed because MOV INDIRECT will write
to all components. Added an assert to verify that these uniforms
are aligned.

v2:
- Fix 'shift' calculation (Curro)
- Set both swizzle and writemask.
- Add assert(shift == 0) for the indirect case.

bfc0c23843 Android: correct libz dependency
Commit 6facb0c0 ("android: fix libz dynamic library dependencies")
unconditionally adds libz as a dependency to all shared libraries.
That is unnecessary.

Commit 85a9b1b5 introduced libz as a dependency to libmesa_util.
So only the shared libraries that use libmesa_util need libz.

Fix Android Lollipop build by adding the include path of zlib to
libmesa_util explicitly instead of getting the path implicitly
from zlib since it doesn't export the include path in Lollipop.

715f47cb34 intel/isl: Refactor gen7_choose_image_alignment_el
The Ivy Bridge PRM provides a nice table that handles most of the
alignment cases in one place.  For standard color buffers we have a
little freedom of choice but for most depth, stencil and compressed it's
hard-coded.  Chad's original functions split halign and valign apart and
implemented them almost entirely based on restrictions and not the
table.  This makes things way more confusing than they need to be.  This
commit gets rid of the split and makes us implement the exact table
up-front.  If our surface isn't one of the ones in the table then we
have to make real choices.

236f17a9f7 intel/isl/gen7: Use stencil vertical alignment of 8 instead of 4
The reasoning Chad gave in the comment for choosing a valign of 4 is
entirely bunk.  The fact that you have to multiply pitch by 2 is
completely unrelated to the halign/valign parameters used for texture
layout.  (Not completely unrelated.  W-tiling is just Y-tiling with a
bit of extra swizzling which turns 8x8 W-tiled chunks into 16x4 y-tiled
chunks so it makes everything easier if miplevels are always aligned to
8x8.)  The fact that RENDER_SURFACE_STATE::SurfaceVerticalAlignmet
doesn't have a VALIGN_8 option doesn't matter since this is gen7 and you
can't do stencil texturing anyway.

v2 (Jason Ekstrand):
 - Delete most of Chad's comment and add a more descriptive commit
   message.

b86dba8a0e nir: Embed the shader_info in the nir_shader again
Commit e1af20f18a changed the shader_info
from being embedded into being just a pointer.  The idea was that
sharing the shader_info between NIR and GLSL would be easier if it were
a pointer pointing to the same shader_info struct.  This, however, has
caused a few problems:

 1) There are many things which generate NIR without GLSL.  This means
    we have to support both NIR shaders which come from GLSL and ones
    that don't and need to have an info elsewhere.

 2) The solution to (1) raises all sorts of ownership issues which have
    to be resolved with ralloc_parent checks.

 3) Ever since 00620782c9, we've been
    using nir_gather_info to fill out the final shader_info.  Thanks to
    cloning and the above ownership issues, the nir_shader::info may not
    point back to the gl_shader anymore and so we have to do a copy of
    the shader_info from NIR back to GLSL anyway.

All of these issues go away if we just embed the shader_info in the
nir_shader.  There's a little downside of having to copy it back after
calling nir_gather_info but, as explained above, we have to do that
anyway.
