It's kind-of an anomaly that the Intel drivers are still treating
gl_FragCoord as an input. It also makes zero sense because we have to
special-case it in the back-end.
Because ANV is the only user of nir_lower_wpos_center, we go ahead and
just update it to look for nir_intrinsic_load_frag_coord as part of this
patch.

This restriction was accidentally added to the BSpec/PRM as an
unrestricted restriction starting with the HSW docs and it was never
removed. However, it only ever applied to HSW and actually potentially
causes problems on BDW and above where we have mipmapped fast-clears.

Cannonlake hardware adds a new resolve type in 3DSTATE_PS called
FAST_CLEAR_0 which does an ambiguate. Now that the hardware can do it
directly, we should use that instead of binding the CCS as a render
target and doing it manually. This was tested with a full Vulkan CTS
run on Cannonlake.

On GLSL that info is set as a layout qualifier when redeclaring
gl_FragCoord, so somehow tied to a specific variable. But in practice,
they behave as a global of the shader. On ARB programs they are set
using a global OPTION (defined at ARB_fragment_coord_conventions), and
on SPIR-V using ExecutionModes, that are also not tied specifically to
the builtin.
This patch moves that info from nir variable and ir variable to nir
shader and gl_program shader_info respectively, so the map is more
similar to SPIR-V, and ARB programs, instead of more similar to GLSL.
FWIW, shader_info.fs already had pixel_center_integer, so this change
also removes some redundancy. Also, as struct gl_program also includes
a shader_info, we removed gl_program::OriginUpperLeft and
PixelCenterInteger, as it would be superfluous.
This change was needed because recently spirv_to_nir changed the order
in which execution modes and variables are handled, so the variables
didn't get the correct values. Now the info is set on the shader
itself, and we don't need to go back to the builtin variable to set
it.
Fixes: e68871f6a ("spirv: Handle constants and types before execution
modes")
v2: (Jason)
* glsl_to_nir: get the info before glsl_to_nir, while all the rest
of the info gathering is happening
* prog_to_nir: gather the info on a general info-gathering pass,
not on variable setup.
v3: (Jason)
* Squash with the patch that removes that info from ir variable
* anv: assert that OriginUpperLeft is true. It should be already
set by spirv_to_nir.
* blorp: set origin_upper_left on its core "compile fragment
shader", not just on some specific places (for this we added an
helper on a previous patch).
* prog_to_nir: no need to gather specifically this fragcoord modes
as the full gl_program shader_info is copied.
* spirv_to_nir: assert that we are a fragment shader when handling
this execution modes.
v4: (reported by failing gitlab pipeline #18750)
* state_tracker: update too due changes on ir.h/gl_program
v5:
* blorp: minor change after change on previous patch
* radeonsi: update due this change.
v6: (Timothy Arceri)
* prog_to_nir: remove extra whitespace
* shader_info: don't use :1 on origin_upper_left
* glsl: program.fs.origin_upper_left/pixel_center_integer can be
move out of the shader list loop
This initializes the nir shader that will be used by blorp. Right now
it doesn't do too much beyond calling nir_builder_init_simple_shader,
and setting a name. More stuff will be added on following patches.
v2: there is a case were it is used a VERTEX_SHADER (Alejandro)
This will allow drivers to pin shader buffers if necessary.
i965 and anv do not need to do this today, but iris will.

For certain EGLImage cases, we represent a single slice or LOD of an

given slice. Most of i965 is fine with this but it breaks blorp. This
is a terrible way to represent slices of a surface in EGL and we should
stop some day but that's a very scary and thorny path. This gets blorp
to start working with those surfaces and fixes some dEQP EGL test bugs.

This pass performs an "ambiguate" operation on a CCS-compressed surface
by manually writing zeros into the CCS. On gen8+, ISL gives us a fairly

because we can only do CCS on single-slice images so we can just blast
over the entire CCS buffer if we want to.

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.

Some defines are used by both i965 and the i965 compiler. Those are

were updated to have the extre include to indicate that.
With future work we might provide a better, split but for now this seems

Previously, we were creating the shader with a NULL ralloc context and then
trusting in blorp_compile_fs to clean it up. The only problem was that
blorp_compile_fs didn't clean up its context properly so we were leaking.
When I went to fix that, I realized that it couldn't because it has to
return the shader binary which is allocated off of that context and used by
the caller. The solution is to make blorp_compile_fs take a ralloc
context, allocate the nir_shaders directly off that context, and clean it
all up in whatever function creates the shader and calls blorp_compile_fs.
