This will be generated by glsl_to_nir, and it turns out that this is a
more code-efficient path than the floating point math, anyway.
No change on shader-db, but drops an instruction in piglit's
glsl-fs-frontfacing.

This is apparently enabled as an error in Android builds, and the compiler
can't tell that the return value is safe.

In a5d7e144eaf43fee37e6ff9e2de194407087632b, Connor generalized the
exec_size halving code to handle more cases. As part of this, he made
it not halve anything if the region accessed falls completely in a
single register.
Unfortunately, it started producing some invalid regions:
-add(16) g6<1>F g10<8,8,1>UW -g1<0,1,0>F { align1 compr };
-add(16) g8<1>F g12<8,8,1>UW -g1.1<0,1,0>F { align1 compr };
+add(16) g6<1>F g10<16,16,1>UW -g1<0,1,0>F { align1 compr };
+add(16) g8<1>F g12<16,16,1>UW -g1.1<0,1,0>F { align1 compr };
Here, the UW source region completely fits within a register. However,
we have to use instruction compression because the destination region
spans two registers. <16,16,1> is invalid because it's compressed.
To handle this, skip the "everything fits in one register" case and
fall through to the exec_size halving case when compressed.
Fixes hundreds of Piglit regressions on GM965.

This enables:
- GL_OES_sample_shading
- GL_OES_sample_variables
- GL_OES_shader_multisample_interpolation
On Gen8, we pass all the CTS tests, and all but 4 of the dEQP-GLES31
tests (dealing with 1x/2x MSAA at half rate sampling). We believe
those 4 dEQP-GLES31 tests are incorrect.

Section 8.9 (Texture Functions) of the OpenGL Shading Language 4.5
specification:
However, automatic level of detail is computed only for fragment shaders.
Other shaders operate as though the base level of detail were computed as
zero.
and Section 8.9.3 (Texture Gather Functions):
When performing a texture gather operation, the minification and
magnification filters are ignored, and the rules for LINEAR filtering in
the OpenGL Specification are applied to the base level of the texture
image to identify the four texels i_0 j_1, i_1 j_1, i_1 j_0, and i_0 j_0.
Of course, explicit LOD or derivative variants work in all shader types.
This fixes several GL4x-CTS.texture_gather.* tests.

texture sampling/fetching opcodes doesn't make much sense.

The format_desc swizzle describes where in the array each color channel
comes from - but the existing code was written as if each entry in the
swizzle described the meaning of an array element.

We also have this barrier call for gen8 vkCmdWaitEvents.
We don't implement waiting on events for gen7 yet, but this barrier at
least helps to not regress CTS cases when data caching is enabled.
Without this, the tests would intermittently report a failure when the
data cache was enabled.

This way we get correct sampling from RGB formats that are faked as RGBA.
This should also cause it to disable rendering and blending on those
formats. We should be able to render to them and, on Broadwell and above,
we can blend on them with work-arounds. However, we'll add support for
that more properly later when it's deemed useful. For now, disabling
rendering and blending should be safe.

The new code removes the switch statement and instead handles depth/stencil
as up-front special cases. This allows for potentially more complicated
color format handling in the future.

This commit removes anv_format_for_vk_format and adds an anv_get_format
helper. The anv_get_format helper returns the anv_format by-value. Unlike
anv_format_for_vk_format the format returned by anv_get_format is 100%
accurate and includes any tweaks needed for tiled vs. linear.
anv_get_isl_format is now just a wrapper around anv_get_format that picks
off just the isl_format.

Now that we have VkFormat introspection and we've removed everything that
tried to use anv_format for introspection, we no longer need most of what
was in anv_format.

Because the buffer is exposed to the user, the block size is defined to
always exactly be the size of the actual vulkan format. This is the same
size (it had better be) as the linaer image format.

As much as I hate adding yet more format introspection, there are times
when the VkFormat is sufficient and we don't want to round-trip through
isl_format. For these times, the new vk_format_info.c/h files provide some
simple driver-agnostic VkFormat introspection. This intended to be
specific to Vulkan but not to any driver whatsoever.
|

This makes several checks easier and allows us to avoid calling
anv_format_for_vk_format in a number of cases.
|
| |
|

|
|
|
|
|

This better maps to the Vulkan object model and also allows WSI to at least
know the hardware generation which is useful for format checks.

Otherwise the instances in the extension XML override the core
definitions, and we stop knowing their sizes in indirect_size_get.c
