st/mesa/radeonsi: fix race between destruction of types and shader compilation

Commit 624789e3708c moved the destruction of types out of atexit() and
made use of a ref count instead. This is useful for avoiding a crash
where drivers such as radeonsi are still compiling in a thread when the app
exits and has not called MakeCurrent to change from the current context.

While the above scenario is technically an app bug we shouldn't crash.
However that change caused another race condition between the shader
compilation tread in radeonsi and context teardown functions.

This patch makes two changes to fix this new problem:

First we explicitly call _mesa_destroy_shader_compiler_types() when destroying
the st context rather than calling it indirectly via _mesa_free_context_data().
We do this as we must call it after st_destroy_context_priv() so that we don't
destory the glsl types before the compilation threads finish.

Next wait for the shader threads to finish in si_destroy_context() this
also means we need to call context destroy before destroying the queues
in si_destroy_screen().

FWIW I think for xf86-video-amdgpu this still requires an X11 config
option, so only people who opt in can get possible regressions from this.

So then the remaining question is: why do this in the WSI?

It has been suggested in another MR that the application sets this.
However, I disagree with that as I don't think we'll ever get a
reasonable set of applications setting it.

The next questions is whether this can be a layer. It definitely
can be as implemented now. However, I think this generally fits
well with the function of the WSI. Furthemore, for e.g. the DISPLAY
WSI this is much harder to do in a layer.

Applications frequently call glBufferSubData() to consecutive regions
of a VBO to append new vertex data.  If no data exists there yet, we
can promote these to unsynchronized writes, even if the buffer is busy,
since the GPU can't be doing anything useful with undefined content.
This can avoid a bunch of unnecessary blitting on the GPU.

u_threaded_context would do this for us, and in fact prohibits us from
doing so (see TC_TRANSFER_MAP_NO_INFER_UNSYNCHRONIZED).  But we haven't
hooked that up yet, and it may be useful to disable u_threaded_context
when debugging...at which point we'd still want this optimization.  At
the very least, it would let us measure the benefit of threading
independently from this optimization.  And it's not a lot of code.

intel/fs: Add a lowering pass for linear interpolation.

On gen11, instead of using a PLN instruction, we convert
FS_OPCODE_LINTERP to 2 or 4 multiply adds. That is done in the
fs_generator code.

This patch adds a lowering pass that does the same thing at the
fs_visitor. It also drops the usage of NF types, since we don't need the
extra precision and it lets us skip the accumulator. With all that, some
optimizations will still be run on the generated code, and we should get
better scheduling.

i965: Ignore uniform storage for samplers or images, use binding info

gl_nir_lower_samplers_as_deref creates new top level sampler and image
uniforms which have been split from structure uniforms.  i965 assumed
that it could walk through gl_uniform_storage slots by starting at
var->data.location and walking forward based on a simple slot count.
This assumed that structure types were walked in a particular order.

With samplers and images split out of structures, it becomes impossible
to assign meaningful locations.  Consider:

   struct S {
      sampler2D a;
      sampler2D b;
   } s[2];

The gl_uniform_storage locations for these follow this map:

   0 => a[0], 1 => b[0], 2 => a[0], 3 => b[0].

But the new split variables look like:

   sampler2D lowered_a[2];
   sampler2D lowered_b[2];

and there is no way to know that there's effectively a stride to get to
the location for successive elements of a[] or b[].  So, working with
location becomes effectively impossible.

Ultimately, the point of looking at uniform storage was to pull out the
bindings from the opaque index fields.  gl_nir_lower_samplers_as_derefs
can obtain this information while doing the splitting, however, and sets
up var->data.binding to have the desired values.

We move gl_nir_lower_samplers before brw_nir_lower_image_load_store so
gl_nir_lower_samplers_as_derefs has the opportunity to set proper image
bindings.  Then, we make the uniform handling code skip sampler(-array)
variables, and handle image param setup based on var->data.binding.

Fixes Piglit tests/spec/glsl-1.10/execution/samplers/uniform-struct,
this time without regressing dEQP-GLES2.functional.uniform_api.random.3.

5 years agoRevert "glsl: Set location on structure-split sampler uniform variables"

Revert "glsl: Set location on structure-split sampler uniform variables"

This reverts commit 9e0c744f07a21fc7bb018a77cf83b057436d0d1b, which
regressed dEQP-GLES2.functional.uniform_api.random.3.  It turns out
that the newly produced location is meaningless and impossible to
consume by drivers that want to look at gl_uniform_storage, so it's
probably better to leave it unset (0) than a number that looks usable.

Leave a tombstone^Wcomment to discourage the next person from making
the obvious looking fix.

See the next commit for a longer description of the problem.

This breaks tests/spec/glsl-1.10/execution/samplers/uniform-struct
on i965, which was originally fixed by the revert.  The next commit
will fix it again.

Marek recently extended pipe->set_shader_buffers() to take an extra

some cross-batch flushing if the SSBO is used for reading in both the
