Andres Gomez [Wed, 27 Feb 2019 13:03:56 +0000 (15:03 +0200)]
GL_ARB_enhanced_layouts: use separable programs

Currently we are testing bogus inputs without a matching counterpart
in the output interface of the previous shader. This is needed since,
otherwise, having a matching output would mean that we would have to
introduce the same error we are trying to test in the input interface
and that could lead to a misleading linking error.

However, not having an output counterpart can also lead to a
misleading linking error.

In other tests we have avoided this by not making a static use of the
tested input. However, when checking for the limit on the number of
input locations that can be used in a specific interface, this
strategy cannot be used since non statically used variable do not
count against this limit.

From page 48 (page 52 of the PDF) of the GLSL 4.60 v.5 spec:

  " There is an implementation-dependent limit on the number of
    locations that can be used, and if this is exceeded it will cause
    a link-time error. (Declared input variables that are not
    statically used do not count against this limit.)"

Therefore, the strategy used for this test is to build individual
separable programs for each stage.

From the ARB_separate_shader_objects spec v.25:

  " With separable program objects, interfaces between shader stages
    may involve the outputs from one program object and the inputs
    from a second program object.  For such interfaces, it is not
    possible to detect mismatches at link time, because the programs
    are linked separately.  When each such program is linked, all
    inputs or outputs interfacing with another program stage are
    treated as active.  The linker will generate an executable that
    assumes the presence of a compatible program on the other side of
    the interface.  If a mismatch between programs occurs, no GL error
    will be generated, but some or all of the inputs on the interface
    will be undefined."

GL_ARB_enhanced_layouts: no static use of inputs

Currently we are testing bogus inputs without a matching counterpart
in the output interface of the previous shader. This is needed since,
otherwise, having a matching output would mean that we would have to
introduce the same error we are trying to test in the input
interface and that could lead to a misleading linking error.

However, not having an output counterpart can also lead to a
misleading linking error. We workaround this by not making a static
use of the tested input.

From page 47 (page 53 of the PDF) of the GLSL 4.60 v.5 spec:

  " Only the input variables that are statically read need to be

    declarations of input variables."

Fix checks for maximum number of samples

Some tests query MAX_SAMPLES and/or MAX_INTEGER_SAMPLES, then
attempt to create FBOs passing MAX_SAMPLES+1 samples and
expecting an error to be reported.

There are a couple of bugs in these tests:

1. One uses GL_RGB10_A2UI which is an integer format and should
   use MAX_INTEGER_SAMPLES instead of MAX_SAMPLES (this is actually
   what the comment above the call says it is doing).

2. Formats can actually support more samples than
   MAX_SAMPLES. As stated for the SAMPLES internal format query:

   "The maximum value in SAMPLES is guaranteed to be at least
    the lowest of the following:
    (...)
    * The value of MAX_SAMPLES"

   The key aspect here is "at least", which means that the
   maximum number reported in SAMPLES can be larger than any
   of the values in the list, which includes MAX_SAMPLES.

As a consequence of 2), it is possible for these tests to fail
because MAX_SAMPLES+1 is a valid number of samples for the target
internal format and not an invalid number like the test intended.

This patch modifies the affected tests to query SAMPLES for the
internal formats used in the checks so we have the actual maximum
number of sample counts supported for each one, that way we ensure
that SAMPLES+1 is always an invalid number of samples.

6 years agoUse less nesting in many arrays of arrays tests.
Kenneth Graunke [Thu, 30 Nov 2017 08:13:35 +0000 (00:13 -0800)]
Use less nesting in many arrays of arrays tests.

Testing 8 levels of array-of-array nesting is very thorough, but a bit
overkill.  It creates a huge amount of register pressure which tends to
slow down compilers, causing the test to take an unreasonable amount of
time to run.  This patch reduces it to 4 levels in many subtests, which
should still be a reasonable amount of testing while running in much
less time.

This cuts the runtime of KHR-GL46.arrays_of_arrays_gl.* by 33 minutes
(43 -> 10) on my laptop's discrete GPU.  With the Intel Mesa driver,
it cuts it by 17 minutes (23 -> 6).

Some tests still exercise 8 levels of nesting, so there's still some
coverage of that scenario.

Iago Toral Quiroga [Thu, 23 Nov 2017 08:30:35 +0000 (09:30 +0100)]
Fix maximum location for varying location limit test

The varying location limit tests for enhanced layouts produces
shader code where it attempts to use a location that is 1 slot
beyond the limit available for each shader stage and expects
linker errors as a result.

However, the functions it uses to compute the maximum location
slot available in a shader stage also consider the stage it will
be linked to to cap that limit (which is required to produce valid
shader code in other tests that also use these functions).

This affects scenarios where, for example, one stage allows up to
32 output locations but the stage it is linked to only accepts
up to 16 inputs. In such scenario, these functions will return
a limit of 16 for the stage that can output 32 so the shader code
produced can link.

However, the varying location limit test intends to produce an
invalid location by adding 1 to the maximum location slot for that
stage (so it wants to produce 32 + 1 = 33 in the case above), so
in this particular case we want the connecting stage to be
ignored.

Add a boolean flag to these functions so we can select between both
behaviors when computing the maximum location for a given stage
and make the varying location limit test force the behavior where
the maximum location in the connecting shader stages is ignored.

over 64 transform feedback components in total, which is larger
than the minimum value that implementations are required to
support for GL_MAX_TRANSFORM_FEEDBACK_INTERLEAVED_COMPONENTS,
which the OpenGL 4.6 spec sets in 64. For implementations that
support this minimum, the generated shaders are invalid and
expected to fail to link.

Check the required component size of the XFB for the generated
shaders and skip them if they exceed the implementation limit.
At worse, for implementations that only support the minimum
number of transform feedback components required by the spec
it would only skip the 3 largest types (out of 34 being tested).

Component aliasing on vertex inputs is allowed

From the OpenGL 4.6 spec, section 11.1 Vertex shaders,
page 384:

"It is possible for an application to bind more than one
 attribute name to the same location. This is referred
 to as aliasing. This will only work if only one of the
 aliased attributes is active in the executable program,
 or if no path through the shader consumes more than one
 attribute of a set of attributes aliased to the same
 location. A link error can occur if the linker determines
 that every path through the shader consumes multiple
 aliased attributes, but implementations are not required
 to generate an error in this case."

The varying_location_aliasing_with_mixed_types enhanced
layouts test generates negative tests to check that
component aliasing produces linker errors for all shader
stages, including vertex shaders when the aliasing occurs
on the vertex inputs. By the citation above, the spec
doesn't mandate implementations to produce an error in
this case, so these particular tests are invalid.

This change removes the test cases that expect an error
to be generated for shaders with component aliasing on
vertex shader inputs.

Delete incorrect invalid map transform feedback subtest.

The citation given in this test comes from the OpenGL man pages, which
are not authoritative.  The ES 3.2 and GL 4.x specifications say:

   "Effects of Mapping Buffers on Other GL Commands

    Any GL command which attempts to read from, write to, or change the
    state of a buffer object may generate an INVALID_OPERATION error if
    all or part of the buffer object is mapped. However, only commands
    which explicitly describe this error are required to do so. If an
    error is not generated, using such commands to perform invalid
    reads, writes, or state changes will have undefined results and may
    result in GL interruption or termination."

Importantly, it says "_may_ generate an INVALID_OPERATION error".  Some
drivers choose not to implement this to avoid the CPU overhead required
to enforce this optional restriction.
