Karol Herbst 909095f60a test_vulkan: Fix some VVL errors (#2486 )

Fixes the following VVL errors:

```
Validation Error: [ VUID-VkExternalSemaphoreProperties-sType-sType ] | MessageID = 0x160be1e8
vkGetPhysicalDeviceExternalSemaphorePropertiesKHR(): pExternalSemaphoreProperties->sType must be VK_STRUCTURE_TYPE_EXTERNAL_SEMAPHORE_PROPERTIES.
The Vulkan spec states: sType must be VK_STRUCTURE_TYPE_EXTERNAL_SEMAPHORE_PROPERTIES (https://docs.vulkan.org/spec/latest/chapters/capabilities.html#VUID-VkExternalSemaphoreProperties-sType-sType)
```

```
Validation Error: [ VUID-VkImportSemaphoreFdInfoKHR-handleType-07307 ] | MessageID = 0x1b609443
vkImportSemaphoreFdKHR(): pImportSemaphoreFdInfo->handleType is VK_EXTERNAL_SEMAPHORE_HANDLE_TYPE_SYNC_FD_BIT so VK_SEMAPHORE_IMPORT_TEMPORARY_BIT must be set, but flags is VkSemaphoreImportFlags(0).
The Vulkan spec states: If handleType refers to a handle type with copy payload transference semantics, flags must contain VK_SEMAPHORE_IMPORT_TEMPORARY_BIT (https://docs.vulkan.org/spec/latest/chapters/synchronization.html#VUID-VkImportSemaphoreFdInfoKHR-handleType-07307)
```

```
Validation Error: [ VUID-VkPhysicalDeviceExternalBufferInfo-None-09500 ] | MessageID = 0x8434cf
vkGetPhysicalDeviceExternalBufferPropertiesKHR(): pExternalBufferInfo->usage is zero.
The Vulkan spec states: If the pNext chain does not include a VkBufferUsageFlags2CreateInfo structure, usage must not be 0 (https://docs.vulkan.org/spec/latest/chapters/capabilities.html#VUID-VkPhysicalDeviceExternalBufferInfo-None-09500)
```

OpenCL Conformance Test Suite (CTS)

This is the OpenCL CTS for all versions of the Khronos OpenCL standard.

Building the CTS

The CTS supports Linux, Windows, macOS, and Android platforms. In particular, GitHub Actions CI builds against Ubuntu 20.04, Windows-latest, and macos-latest.

Compiling the CTS requires the following CMake configuration options to be set:

CL_INCLUDE_DIR Points to the unified OpenCL-Headers.
SPIRV_INCLUDE_DIR Points to the unified SPIRV-Headers.
CL_LIB_DIR Directory containing the OpenCL library to build against.
SPIRV_TOOLS_DIR Directory containing the spirv-as and spirv-val binaries to be used in the CTS build process. Alternatively, the location to these binaries can be provided via the PATH variable.
OPENCL_LIBRARIES Name of the OpenCL library to link.

It is advised that the OpenCL ICD-Loader is used as the OpenCL library to build against. Where CL_LIB_DIR points to a build of the ICD loader and OPENCL_LIBRARIES is "OpenCL".

Example Build

Steps on a Linux platform to clone dependencies from GitHub sources, configure a build, and compile.

git clone https://github.com/KhronosGroup/OpenCL-CTS.git
git clone https://github.com/KhronosGroup/OpenCL-Headers.git
git clone https://github.com/KhronosGroup/SPIRV-Headers.git
git clone https://github.com/KhronosGroup/OpenCL-ICD-Loader.git
git clone https://github.com/KhronosGroup/SPIRV-Tools.git
git clone https://github.com/KhronosGroup/SPIRV-Headers.git SPIRV-Tools/external/spirv-headers
git clone https://github.com/google/effcee.git SPIRV-Tools/external/effcee
git clone https://github.com/google/re2.git SPIRV-Tools/external/re2


mkdir OpenCL-ICD-Loader/build
cmake -S OpenCL-ICD-Loader -B OpenCL-ICD-Loader/build \
      -DOPENCL_ICD_LOADER_HEADERS_DIR=$PWD/OpenCL-Headers
cmake --build ./OpenCL-ICD-Loader/build --config Release

mkdir SPIRV-Tools/build
cmake -S SPIRV-Tools -B SPIRV-Tools/build -DSPIRV_SKIP_TESTS=ON
cmake --build SPIRV-Tools/build --config Release

mkdir OpenCL-CTS/build
cmake -S OpenCL-CTS -B OpenCL-CTS/build \
      -DCL_INCLUDE_DIR=$PWD/OpenCL-Headers \
      -DSPIRV_INCLUDE_DIR=$PWD/SPIRV-Headers \
      -DCL_LIB_DIR=$PWD/OpenCL-ICD-Loader/build \
      -DSPIRV_TOOLS_DIR=$PWD/SPIRV-Tools/build/tools/ \
      -DOPENCL_LIBRARIES=OpenCL
cmake --build OpenCL-CTS/build --config Release

Running the CTS

A build of the CTS contains multiple executables representing the directories in the test_conformance folder. Each of these executables contains sub-tests, and possibly smaller granularities of testing within the sub-tests.

See the --help output on each executable for the list of sub-tests available, as well as other options for configuring execution.

If the OpenCL library built against is the ICD Loader, and the vendor library to be tested is not registered in the default ICD Loader location then the OCL_ICD_FILENAMES environment variable will need to be set for the ICD Loader to detect the OpenCL library to use at runtime. For example, to run the basic tests on a Linux platform:

OCL_ICD_FILENAMES=/path/to/vendor_lib.so ./test_basic

Offline Compilation

Testing OpenCL drivers which do not have a runtime compiler can be done by using additional command line arguments provided by the test harness for tests which require compilation, these are:

--compilation-mode Selects if OpenCL-C source code should be compiled using an external tool before being passed on to the OpenCL driver in that form for testing. Online is the default mode, but also accepts the values spir-v, and binary.
--compilation-cache-mode Controls how the compiled OpenCL-C source code should be cached on disk.
--compilation-cache-path Accepts a path to a directory where the compiled binary cache should be stored on disk.
--compilation-program Accepts a path to an executable (default: cl_offline_compiler) invoked by the test harness to perform offline compilation of OpenCL-C source code. This executable must match the interface description.

Generating a Conformance Report

The Khronos Conformance Process Document details the steps required for a conformance submission. In this repository opencl_conformance_tests_full.csv defines the full list of tests which must be run for conformance. The output log of which must be included alongside a filled in submission details template.

Utility script run_conformance.py can be used to help generating the submission log, although it is not required.

Git tags are used to define the version of the repository conformance submissions are made against.

Contributing

Contributions are welcome to the project from Khronos members and non-members alike via GitHub Pull Requests (PR). Alternatively, if you've found a bug or have a question please file an issue in the GitHub project. First time contributors will be required to sign the Khronos Contributor License Agreement (CLA) before their PR can be merged.

PRs to the repository are required to be clang-format clean to pass CI. Developers can either use the git-clang-format tool locally to verify this before contributing, or update their PR based on the diff provided by a failing CI job.
