From becc87b84a01d0b9c6efb5a979dfb44c53095c4d Mon Sep 17 00:00:00 2001 From: Samuel Pitoiset Date: Thu, 20 Apr 2017 19:13:50 +0200 Subject: [PATCH] glsl: make sampler/image types as 64-bit MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The ARB_bindless_texture spec says: "Samplers are represented using 64-bit integer handles." and, "Images are represented using 64-bit integer handles." It seems simpler to always consider sampler and image types as 64-bit unsigned integer. This introduces a temporary workaround in _mesa_get_uniform() because at this point no flag are used to distinguish between bound and bindless samplers. This is going to be removed in a separate series. This avoids breaking arb_shader_image_load_store-state. v3: - update the comment slightly Signed-off-by: Samuel Pitoiset Reviewed-by: Nicolai Hähnle Reviewed-by: Timothy Arceri --- src/compiler/glsl_types.h | 4 +++- src/mesa/main/uniform_query.cpp | 6 +++++- 2 files changed, 8 insertions(+), 2 deletions(-) diff --git a/src/compiler/glsl_types.h b/src/compiler/glsl_types.h index 9885866..a81b8fe 100644 --- a/src/compiler/glsl_types.h +++ b/src/compiler/glsl_types.h @@ -72,7 +72,9 @@ static inline bool glsl_base_type_is_64bit(enum glsl_base_type type) { return type == GLSL_TYPE_DOUBLE || type == GLSL_TYPE_UINT64 || - type == GLSL_TYPE_INT64; + type == GLSL_TYPE_INT64 || + type == GLSL_TYPE_IMAGE || + type == GLSL_TYPE_SAMPLER; } enum glsl_sampler_dim { diff --git a/src/mesa/main/uniform_query.cpp b/src/mesa/main/uniform_query.cpp index 114f6fb..0e02a76 100644 --- a/src/mesa/main/uniform_query.cpp +++ b/src/mesa/main/uniform_query.cpp @@ -322,7 +322,11 @@ _mesa_get_uniform(struct gl_context *ctx, GLuint program, GLint location, { unsigned elements = uni->type->components(); - const int dmul = uni->type->is_64bit() ? 2 : 1; + /* XXX: Remove the sampler/image check workarounds when bindless is fully + * implemented. + */ + const int dmul = + (uni->type->is_64bit() && !uni->type->is_sampler() && !uni->type->is_image()) ? 2 : 1; const int rmul = glsl_base_type_is_64bit(returnType) ? 2 : 1; /* Calculate the source base address *BEFORE* modifying elements to -- 2.7.4
