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.

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'.

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.

i965/gen6/blorp: Set need_workaround_flush at top of blorp
Unconditionally set brw->need_workaround_flush at the top of gen6 blorp

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.

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.

The ES and desktop GL specs diverge here. Yay!
In desktop OpenGL, the driver can perform online compression of
uncompressed texture data. GL_NUM_COMPRESSED_TEXTURE_FORMATS and
GL_COMPRESSED_TEXTURE_FORMATS give the application a list of formats
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."

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.

The compiler back-ends (i965's fs_visitor and brw_visitor,
ir_to_mesa_visitor, and glsl_to_tgsi_visitor) assume that when
ir_loop::counter is non-null, it points to a fresh ir_variable that
should be used as the loop counter (as opposed to an ir_variable that
exists elsewhere in the instruction stream).
However, previous to this patch:
(1) loop_control_visitor did not create a new variable for
ir_loop::counter; instead it re-used the existing ir_variable.
This caused the loop counter to be double-incremented (once
explicitly by the body of the loop, and once implicitly by
ir_loop::increment).
(2) ir_clone did not clone ir_loop::counter properly, resulting in the
cloned ir_loop pointing to the source ir_loop's counter.
(3) ir_hierarchical_visitor did not visit ir_loop::counter, resulting
in the ir_variable being missed by reparenting.
Additionally, most optimization passes (e.g. loop unrolling) assume
that the variable mentioned by ir_loop::counter is not accessed in the
body of the loop (an assumption which (1) violates).
The combination of these factors caused a perfect storm in which the
code worked properly nearly all of the time: for loops that got
unrolled, (1) would introduce a double-increment, but loop unrolling
would fail to notice it (since it assumes that ir_loop::counter is not
accessed in the body of the loop), so it would unroll the loop the
correct number of times. For loops that didn't get unrolled, (1)
would introduce a double-increment, but then later when the IR was
cloned for linking, (2) would prevent the loop counter from being
cloned properly, so it would look to further analysis stages like an
independent variable (and hence the double-increment would stop
occurring). At the end of linking, (3) would prevent the loop counter
from being reparented, so it would still belong to the shader object
rather than the linked program object. Provided that the client
program didn't delete the shader object, the memory would never get
reclaimed, and so the shader would function properly.
However, for loops that didn't get unrolled, if the client program did
delete the shader object, and the memory belonging to the loop counter
got re-used, this could cause a use-after-free bug, leading to a
crash.
This patch fixes loop_control_visitor, ir_clone, and
ir_hierarchical_visitor to treat ir_loop::counter the same way the
back-ends treat it: as a freshly allocated ir_variable that needs to
be visited and cloned independently of other ir_variables.

account for this in ir_variable_refcount, otherwise there is a danger
we will try to dead-code-eliminate the loop counter variable.
Note: at the moment the dead code elimination bug doesn't occur due to
a bug in ir_hierarchical_visitor: it doesn't visit the "counter"
field, so dead code elimination doesn't treat it as a candidate for
elimination. But the patch to follow will fix that bug, so we need to

(cherry picked from commit 38366c0c6e)
On evergreen we have to reserve 1 stack element in some additional cases
besides the ones mentioned in the docs, but stack size computation was
recently reimplemented exactly as described in the docs by the patch that
added workarounds for stack issues on EG/CM, resulting in regressions
with some apps (Serious Sam 3).
This patch fixes it by restoring previous behavior.

I'm not sure why this change is necessary. When I've built previous tar files
(such as 9.2.4) with the "make tarballs" target, they include the
bin/test-driver file. But at my first attempt to build the tar files for the
10.0.1 release this file was not being included and the build failed.
First off, nv50_program only has 16 in/out varyings. However reporting
16 makes 'm' become 68 in nv50_fp_linkage_validate with the
varying-packing-simple piglit test. (Subverting the assert makes it
compile but fail.) With this patch, varying-packing-simple passes.

If we're not using EGL_EXT_swap_buffers_with_damage, we have to
damage the full extent. EGL operates on buffer coordinates, but
wl_surface.damage takes surface coordinates. EGL doesn't know the
buffer transformation (rotated or scaled) and can't post accurate
damage in surface coordinates. The damage event however is clipped to
the surface extents so we can just damage the maximum rectangle.
In case of EGL_EXT_swap_buffers_with_damage, the application knows
the buffer transform and is expected to pass in rectangles in
surface space.

On gen6, multisamble resolve blits use the SAMPLE message to blend
together the 4 samples for each texel. For some reason, SAMPLE
doesn't blend together the proper samples when the source format is
L32_FLOAT or I32_FLOAT, resulting in blocky artifacts.
To work around this problem, sample from the source surface using
R32_FLOAT. This shouldn't affect rendering correctness, because when
doing these resolve blits, the destination format is R32_FLOAT, so the
channel replication done by L32_FLOAT and I32_FLOAT is unnecessary.

(cherry picked from commit 53a65e547c)
In commit 065da16 (glsl: Convert lower_clip_distance_visitor to be an
ir_rvalue_visitor), we failed to notice that since
lower_clip_distance_visitor overrides visit_leave(ir_assignment *),
ir_rvalue_visitor::visit_leave(ir_assignment *) wasn't getting called.
As a result, clip distance dereferences appearing directly on the
right hand side of an assignment (not in a subexpression) weren't
getting properly lowered. This caused an ir_dereference_variable node
to be left in the IR that referred to the old gl_ClipDistance
variable. However, since the lowering pass replaces gl_ClipDistance
with gl_ClipDistanceMESA, this turned into a dangling pointer when the
IR got reparented.
Prior to the introduction of geometry shaders, this bug was unlikely
to arise, because (a) reading from gl_ClipDistance[i] in the fragment
shader was rare, and (b) when it happened, it was likely that it would
either appear in a subexpression, or be hoisted into a subexpression
by tree grafting.
However, in a geometry shader, we're likely to see a statement like
this, which would trigger the bug:
gl_ClipDistance[i] = gl_in[j].gl_ClipDistance[i];
This patch causes
lower_clip_distance_visitor::visit_leave(ir_assignment *) to call the
base class visitor, so that the right hand side of the assignment is
properly lowered.

Previously, in brw_gs_upload_binding_table(), we checked whether
brw->gs.prog_data was NULL in order to determine whether a geometry
shader was active. This didn't work: brw->gs.prog_data starts off as
NULL, but it is set to non-NULL when a geometry shader program is
built, and then never set to NULL again. As a result, if we called
brw_gs_upload_binding_table() while there was no geometry shader
active, but a geometry shader had previously been active, it would
refer to a stale (and possibly freed) prog_data structure.
This patch fixes the problem by modifying
brw_gs_upload_binding_table() to use the proper technique to determine
whether a geometry shader is active: by checking whether
brw->geometry_program is NULL.
This fixes the crash reported in comment 2 of bug 71870 (the incorrect

Previously, when doing intrastage and interstage interface block
linking, we only checked the interface type; this prevented us from
catching some link errors.
We now check the following additional constraints:
- For intrastage linking, the presence/absence of interface names must
match.
- For shader ins/outs, the interface names themselves must match when
doing intrastage linking (note: it's not clear from the spec whether
this is necessary, but Mesa's implementation currently relies on
it).
- Array vs. nonarray must be consistent, taking into account the
special rules for vertex-geometry linkage.
- Array sizes must be consistent (exception: during intrastage
linking, an unsized array matches a sized array).
Note: validate_interstage_interface_blocks currently handles both
uniforms and in/out variables. As a result, if all three shader types
are present (VS, GS, and FS), and a uniform interface block is
mentioned in the VS and FS but not the GS, it won't be validated. I
plan to address this in later patches.

or for a multisampled (8x) render target, since these surfaces
support only alignment of 4.
Back in 2012 when we added multisampling support to the i965 driver,
we forgot to update the logic for computing the vertical alignment, so
we were often using a vertical alignment of 2 for multisampled
buffers, leading to subtle rendering errors.
Note that the specs also require a vertical alignment of 4 for all
Y-tiled render target surfaces; I plan to address that in a separate
patch.

For both vertex and fragment shaders we default MaxUniformComponents
to 4 * MAX_UNIFORMS. It makes sense to do this for geometry shaders
too; if back-ends have different limits they can override them as
necessary.

This lets us allocate color buffers as __DRIimages and pass them into
the driver instead of having to create a __DRIbuffer with the flink
that requires.
With this patch, we can now run gbm on render-nodes. A render-node is a
drm device that doesn't support modesetting and all the legacy DRI ioctls.
flink is also not supported, but now that gbm doesn't need flink, we can
run piglit on head-less gbm or head-less GPGPU.

Since LIFO fails on some shaders in one particular way, and non-LIFO
systematically fails in another way on different kinds of shaders, try
them both, and pick whichever one successfully register allocates first.
Slightly prefer non-LIFO in case we produce extra dependencies in register
allocation, since it should start out with fewer stalls than LIFO.
This is madness, but I haven't come up with another way to get unigine
tropics to not spill while keeping other programs from not spilling and
retaining the non-unigine performance wins from texture-grf.

Long ago, the HW_REG usage in assign_curb/urb_setup() were scheduling
barriers, so we had to run scheduler before them in order for it to be
able to do basically anything. Now that that's fixed, we can delay the
scheduling until we go to allocate (which will make the next change less
scary).

We care about depth-until-program-end, as a proxy for "make sure I

schedule for the hardware).

In the SIMD16 spilling changes, I replaced a "1" in the spill path with
"mlen", but obviously it wasn't mlen before because spills have the g0
header along with the payload. The interface I was trying to use was
asking for how many physical regs we're writing, so we're looking for "1"
or "2".
I'm guessing this actually passed piglit because the high 8 bits of the
execution mask in SIMD8 mode are all 0s.

(cherry picked from commit 7c90947a0b)
Previously, the best thing we had was to schedule the things unblocked by
the last chosen instruction, on the hope that it would be consuming two
values at the end of their live intervals while only producing one new
value. But that's just a guess, and we can do counting of usage of
registers to know when an instruction would (almost surely) reduce
register pressure.
The only failure mode I know of in this new dominant heuristic is that
inside of a loop when scheduling the iterator (for example), choosing the
last use of the iterator doesn't actually reduce the live interval of the
iterator. But it doesn't seem to matter in shader-db:
total instructions in shared programs: 1618700 -> 1618700 (0.00%)
instructions in affected programs: 0 -> 0
GAINED: 13
LOST: 0
Note: The new functions are made virtual because I expect we'll soon lift
the pre-regalloc scheduling heuristic over to the vec4 backend.

Otherwise, the function would enable generic vertex attributes 0

Commit b16b3c87 began performing CSE on CMP instructions with null
destinations. I relaxed the restrictions a bit too much, thereby
allowing CSE to be performed on instructions with, for instance, an
explicit accumulator destination.
This broke the arb_gpu_shader5/fs-imulExtended shader tests because
they emit MUL instructions with the accumulator as the destination. CSE
would instead cause the MUL to write to a GRF, which is lower precision
than the accumulator.
