9 years agogallivm: Allow drivers and state trackers to initialize gallivm LLVM targets v2
Tom Stellard [Thu, 24 Sep 2015 15:57:02 +0000 (15:57 +0000)]
gallivm: Allow drivers and state trackers to initialize gallivm LLVM targets v2

Drivers and state trackers that use LLVM for generating code, must
register the targets they use with LLVM's global TargetRegistry.
The TargetRegistry is not thread-safe, so all targets must be added
to the registry before it can be queried for target information.

When drivers and state trackers initialize their own targets, they need
a way to force gallivm to initialize its targets at the same time.
Otherwise, there can be a race condition in some multi-threaded
applications (e.g. glx-multihreaded-shader-compile in piglit),
when one thread creates a context for a driver that uses LLVM (e.g.
radeonsi) and another thread creates a gallivm context (glxContextCreate
does this).

The race happens when the driver thread initializes its LLVM targets and
then starts using the registry before the gallivm thread has a chance to
register its targets.

This patch allows users to force gallivm to register its targets by
calling the gallivm_init_llvm_targets() function.

v2:
  - Use call_once and remove mutexes and static initializations.
  - Replace gallivm_init_llvm_{begin,end}() with
    gallivm_init_llvm_targets().

i965/nir: Refactor input/output lowering setup into helpers.

The code for input lowering is going to get significantly more
complicated shortly, so I wanted to pull it out.  Vertex shader inputs
are handled nearly identically regardless of vec4/scalar mode, so I
opted to not split that.

I thought about having each function actually do the lowering, but one
pass through nir_lower_io that handles all types (which weren't handled
earlier) is probably more efficient.

9 years agometa: Handle array textures in scaled MSAA blits
Ian Romanick [Tue, 22 Sep 2015 21:42:32 +0000 (14:42 -0700)]
meta: Handle array textures in scaled MSAA blits

The old code had some significant problems with respect to
sampler2DArray textures.  The biggest problem was that some of the code
would use vec3 for the texture coordinate type, and other parts of the
code would use vec2.  The resulting shader would not even compile.
Since there were not tests for this path, nobody noticed.

The input to the fragment shader is always treated as a vec3.  If the
source data is only vec2, the vertex puller will supply 0 for the .z
component.  The texture coordinate passed to the fragment shader is
always a vec2 that comes from the .xy part of the vertex shader input.
The layer, taken from the .z of the vertex shader input is passed
separately as a flat integer.  If the generated fragment shader does not
use the layer integer, the GLSL linker will eliminate all the dead code
in the vertex shader.

Fixes the new piglit tests "blit-scaled samples=2 with
gl_texture_2d_multisample_array", etc. on i965.

Note for stable maintainer: This patch may depend on 46037237, and that
patch should be safe for stable.
