This document describes how to build and run Vulkan Conformance Test suite.
Vulkan CTS is built on the dEQP framework. Up-to-date documentation for dEQP is available at:
The following tools must be installed and present in the PATH variable:
- Git (for checking out sources)
- Python 3.x (for the build related scripts, some other scripts still use Python 2.7.x)
- CMake 3.20.0 or newer
- Visual Studio 2015 or newer (glslang uses several C++11 features)
- Standard toolchain (make, gcc/clang)
- If you have X11 installed, then the build assumes you also have the
GL/glx.hheader file.- You can get this from the
mesa-common-devUbuntu package.
- You can get this from the
- Xcode
Vulkan SDK for macOS includes a MoltenVK runtime library which is recommended method for developing a Vulkan application.
- Android NDK r17c or later.
- Android SDK with: SDK Tools, SDK Platform-tools, SDK Build-tools, and API 28
- Java Development Kit (JDK)
- Windows: either NMake or Ninja in PATH
If you have downloaded the Android SDK command line tools package (25.2.3 or higher) then you can install the necessary components by running:
tools/bin/sdkmanager tools platform-tools 'build-tools;25.0.2' 'platforms;android-28'
To build dEQP, you need first to download sources for zlib, libpng, jsoncpp, glslang, vulkan-docs, spirv-headers, and spirv-tools.
To download sources, run:
python3 external/fetch_sources.py
You may need to re-run fetch_sources.py to update to the latest glslang,
vulkan-docs and spirv-tools revisions occasionally.
You also need to install lxml python module by running:
python3 -m pip install lxml
With CMake out-of-source builds are always recommended. Create a build directory of your choosing, and in that directory generate Makefiles or IDE project using cmake.
cmake <path to vulkancts> -G"Visual Studio 14"
start dEQP-Core-default.sln
cmake <path to vulkancts> -G"Visual Studio 14 Win64"
start dEQP-Core-default.sln
cmake <path to vulkancts> -DCMAKE_BUILD_TYPE=Debug -DCMAKE_C_FLAGS=-m32 -DCMAKE_CXX_FLAGS=-m32
make -j
Release build can be done by using -DCMAKE_BUILD_TYPE=Release
If building for 32-bit x86 with GCC, you probably also want to add -msse2 -mfpmath=sse to ensure that you get correct IEEE floating-point behavior.
cmake <path to vulkancts> -DCMAKE_BUILD_TYPE=Debug -DCMAKE_C_FLAGS=-m64 -DCMAKE_CXX_FLAGS=-m64
make -j
cmake <path to vulkancts> -DCMAKE_BUILD_TYPE=Debug -DDEQP_TARGET=osx -DCMAKE_C_FLAGS=-m64 -DCMAKE_CXX_FLAGS=-m64
make -j
There's two types of builds for Android:
This builds an APK that needs to be invoked via adb shell and the output needs
to be read via adb logcat, it's the preferred way for long-running invocations
on Android since it doesn't depend on an active connection from the host PC.
Following command will build dEQP.apk:
python3 scripts/android/build_apk.py --sdk <path to Android SDK> --ndk <path to Android NDK>
By default the CTS package will be built for the Android API level 28. Another API level may be supplied using --native-api command line option.
The package can be installed by either running:
python3 scripts/android/install_apk.py
By default the CTS package will contain libdeqp.so built for armeabi-v7a, arm64-v8a,
x86, and x86_64 ABIs, but that can be changed at build time by passing the --abis command line
option to scripts/android/build_apk.py.
To pick which ABI to use at install time, use the following command instead:
adb install -g --abi <ABI name> <build-root>/package/dEQP.apk
This is identical to the builds on other platforms and is better for iterative runs of headless tests as CTS can be invoked and the output can be checked from a single interactive terminal.
This build doesn't support WSI tests and shouldn't be used for conformance
submissions, it also isn't recommended for longer running tests since Android
will terminate this process as soon as the adb shell session ends which may
happen due to an unintentional device disconnection.
cmake <path to vulkancts> -GNinja -DCMAKE_BUILD_TYPE=Debug \
-DCMAKE_TOOLCHAIN_FILE=<NDK path>/build/cmake/android.toolchain.cmake \
-DCMAKE_ANDROID_NDK=<NDK path> -DANDROID_ABI=<ABI to build eg: arm64-v8a> \
-DDE_ANDROID_API=<API level> -DDEQP_TARGET_TOOLCHAIN=ndk-modern \
-DDEQP_TARGET=android -DDEQP_ANDROID_EXE=ON
ninja all
The build needs to be transferred to the device via adb push to a directory
under /data/ on the device, such as /data/local/tmp/ which should be writeable
for non-rooted devices. It should be noted that anywhere on /sdcard/ won't work
since it's mounted as noexec.
Current Vulkan mustpass is checked into repository and can be found at:
external/vulkancts/mustpass/main/vk-default.txt
Current Vulkan SC mustpass can be found at:
external/vulkancts/mustpass/main/vksc-default.txt
This file contains list of files located in vk-default or vksc-default subdirectory. Those files contain tests from bigest test groups and together they contain all test cases that should pass.
Vulkan CTS mustpass can be re-generated by running:
python3 <vulkancts>/external/vulkancts/scripts/build_mustpass.py
Following command line options MUST be used when running CTS:
--deqp-caselist-file=<vulkancts>/external/vulkancts/mustpass/main/vk-default.txt (or vksc-default.txt for Vulkan SC implementations)
--deqp-log-images=disable
--deqp-log-shader-sources=disable
If an implementation ships with implicit layers enabled, then such layers must be enabled when running CTS.
In addition, on multi-device systems the device for which conformance is claimed can be selected with:
--deqp-vk-device-id=<value>
To speed up the conformance run on some platforms the following command line option may be used to disable frequent fflush() calls to the output logs:
--deqp-log-flush=disable
By default, the test log will be written into the path "TestResults.qpa". If the platform requires a different path, it can be specified with:
--deqp-log-filename=<path>
By default, the CTS will expect to find its test resource files in the current working directory. This can be overridden with:
--deqp-archive-dir=<path>
By default, the shader cache will be written into the path "shadercache.bin". If the platform requires a different path, it can be specified with:
--deqp-shadercache-filename=<path>
If the shader cache is not desired, it can be disabled with:
--deqp-shadercache=disable
CTS execution may be split into N fractions ( for the purpose of running it in parallel ) using
--deqp-fraction=I,N
where I denotes index of current CTS execution ( I=[0..N-1], N=[1..16] )
When collecting results for a Conformance Submission Package the number of fractions must not exceed 16, and a list of mandatory information tests for each fraction must be supplied:
--deqp-fraction-mandatory-caselist-file=<vulkancts>external/vulkancts/mustpass/main/vk-fraction-mandatory-tests.txt
To specify file containing waived tests that are omitted only by specified vendor and renderer/device the following command line option may be used:
--deqp-waiver-file=<path>
To make log more clear for high level shader source analysis output of decompiled SPIR-V shader sources can be disabled:
--deqp-log-decompiled-spirv=disable
Also non-informative empty LogInfo sections can be removed from output into log by specifying:
--deqp-log-empty-loginfo=disable
Vulkan compute-only implementations must be tested using option
--deqp-compute-only=enable
There are several additional options used only in conjunction with Vulkan SC tests ( for Vulkan SC CTS tests deqp-vksc application should be used ).
To define minimum size of the command pool use parameter:
--deqp-command-pool-min-size=<value>
To define minimum size of a single command buffer use parameter:
--deqp-command-buffer-min-size=<value>
If minimum size will not be defined, then the size of single command buffer will be estimated from number of commands multiplied by value of parameter deqp-command-default-size. Default size of a single command may be defined using:
--deqp-command-default-size=<value>
Another group of Vulkan SC options enable use of offline pipeline compiler:
--deqp-pipeline-compiler=<value>
--deqp-pipeline-dir=<value>
--deqp-pipeline-args=<value>
--deqp-pipeline-file=<value>
--deqp-pipeline-logfile=<value>
--deqp-pipeline-prefix=<value>
In case of offline pipeline compilers the size of the pipeline will be returned by pipeline compiler. If we use internal pipeline compilation then pipeline size will be equal to default size. This size may be modified using:
--deqp-pipeline-default-size=<value>
Vulkan SC may be implemented on embedded platform that is not able to read from/write to files, write logs, etc. In this case you may use external server that will perform these tasks on another machine:
--deqp-server-address=<value>
In Vulkan SC CTS tests are performed twice. You may define how many tests are performed on separate process in a single batch:
--deqp-subprocess-test-count=<value>
Above mentioned parameter works as default value for all tests. You may also define how many tests are performed on a separate process for specific test tree branch using parameter:
--deqp-subprocess-cfg-file=<path>
File should contain test pattern followed by numeric value, for example: dEQP-VKSC.api.copy_and_blit.core.image_to_image.dimensions.src32768x4_dst32768x4., 5 dEQP-VKSC.texture.explicit_lod.2d.sizes., 20 dEQP-VKSC.texture.explicit_lod.2d.sizes.128x128_*, 4
There is also one option used by CTS internally and should not be used manually. It informs deqp-vksc application that it works as subprocess:
--deqp-subprocess=[enable|disable]
No other command line options are allowed.
Vulkan:
cd <builddir>/external/vulkancts/modules/vulkan
Debug\deqp-vk.exe --deqp-caselist-file=...
Vulkan SC:
cd <builddir>/external/vulkancts/modules/vulkan
Debug\deqp-vksc.exe --deqp-caselist-file=...
Test log will be written into TestResults.qpa
Vulkan:
cd <builddir>/external/vulkancts/modules/vulkan
./deqp-vk --deqp-caselist-file=...
Vulkan SC:
cd <builddir>/external/vulkancts/modules/vulkan
./deqp-vksc --deqp-caselist-file=...
cd <builddir>/external/vulkancts/modules/vulkan
./deqp-vk --deqp-caselist-file=...
For Android build using SDK 29 or greater, it is recommended to use /sdcard/Documents/ instead of /sdcard/ due to scoped storage.
adb push <vulkancts>/external/vulkancts/mustpass/main/vk-default.txt /sdcard/vk-default.txt
adb shell
In device shell:
am start -n com.drawelements.deqp/android.app.NativeActivity -e cmdLine "deqp --deqp-caselist-file=/sdcard/vk-default.txt --deqp-log-images=disable --deqp-log-shader-sources=disable --deqp-log-filename=/sdcard/TestResults.qpa"
Test progress will be written to device log and can be displayed with:
adb logcat -s dEQP
Test log will be written into /sdcard/TestResults.qpa.
Identical to Linux, but within adb shell instead:
adb shell
> cd <pushed build directory>/external/vulkancts/modules/vulkan
> ./deqp-vk --deqp-caselist-file=...
The conformance submission package must contain the following:
- Full test logs (
TestResults.qpa) from CTS runs against all driver builds and all fractions - Result of
git statusandgit logfrom CTS source directory - Any patches used on top of release tag
- Conformance statement
Test logs (1) should be named <submission pkg dir>/TestResults-<driver build type>-<fraction id>-of-<total fractions>.qpa,
for example TestResults-armeabi-v7a-1-of-8.qpa. On platforms where multiple different driver
builds (for example 64-bit and 32-bit) are present, CTS logs must be provided
for each driver build as part of the submission package. If CTS run was split into multiple
fractions then result files for all fractions must be provided, each file must
contain results of the mandatory information tests.
Fractions may be run on different physical devices but each device must represent the same Conformant Product.
Test logs generated on a system which exposes more than one physical device in a device group can be used for products that expose one or more physical devices in their device group.
The CTS build must always be done from clean git repository that doesn't have any
uncommitted changes. Thus it is necessary to run and capture output of git status and git log (2) in the source directory:
git status > <submission pkg dir>/git-status.txt
git log --first-parent <release tag>^..HEAD > <submission pkg dir>/git-log.txt
Any changes made to CTS must be committed to the local repository, and provided as part of the submission package (3). This can be done by running:
git format-patch -o <submission pkg dir> <release tag>..HEAD
Changes to platform-specific code (mostly under framework/platform)
are allowed. The commit message for each change must include a clear
description of the change and why it is necessary.
For Vulkan SC, changes are also permitted to the following:
- vksc-pipeline-compiler (under
vkscpc/) - vksc-server (under
vkscserver/) - modules/vulkan/sc/vktApplicationParametersTests.cpp (to provide vendor-specific test data)
Bugfixes to the tests are allowed. Before being used for a submission,
bugfixes must be accepted and merged into the CTS repository.
git cherry-pick is strongly recommended as a method of applying bug fixes.
If command line parameter --deqp-subprocess-cfg-file was used then the file pointed by this parameter must also be added to submission package.
Other changes must be accompanied by a waiver (see below).
NOTE: When cherry-picking patches on top of release tag, please use git cherry-pick -x
to include original commit hash in the commit message.
Conformance statement (4) must be included in a file called STATEMENT-<adopter>
and must contain following:
CONFORM_VERSION: <git tag of CTS release>
PRODUCT: <string-value>
CPU: <string-value>
OS: <string-value>
Note that product/cpu/os information is also captured in dEQP-VK.info.* tests
if vk::Platform::describePlatform() is implemented.
If the submission package covers multiple products, you can list them by appending
additional PRODUCT: lines to the conformance statement. For example:
CONFORM_VERSION: vulkan-cts-1.2.6.0
PRODUCT: Product A
PRODUCT: Product B
...
The actual submission package consists of the above set of files which must be bundled into a gzipped tar file.
For Vulkan this must be named VK<API major><API minor>_<adopter><_info>.tgz.
For Vulkan SC this must be named VKSC<API major><API minor>_<adopter><_info>.tgz.
<API major> is the major version of the Vulkan {SC} API specification.
<API minor>is the minor version of the Vulkan {SC} API specification.
<adopter> is the name of the Adopting member company, or some recognizable abbreviation.
The <_info> field is optional. It may be used to uniquely identify a submission
by OS, platform, date, or other criteria when making multiple submissions.
For example, a company XYZ may make a submission for a Vulkan 1.1 implementation named
VK11_XYZ_PRODUCTA_Windows10.tgz
One way to create a suiteable gzipped tar file is to execute the command:
tar -cvzf <filename.tgz> -C <submission pkg dir> .
where <submission pkg dir> is the directory containing the files from (1)-(4)
from above. A submission package must contain all of the files listed above,
and only those files.
As an example submission package could contain:
STATEMENT-Khronos
git-log.txt
git-status.txt
0001-Remove-Waived-Filtering-Tests.patch
0002-Fix-Pipeline-Parameters.patch
TestResults-armeabi-v7a.qpa
TestResults-arm64-v8a.qpa
The process for requesting a waiver is to report the issue by filing a bug report in the Gitlab VulkanCTS project (TODO Github?). When creating the submission package, include references to the waiver in the commit message of the relevant change. Including as much information as possible in your bug report (including a unified diff or a merge request of suggested file changes) will ensure the issue can be progressed as rapidly as possible. Issues must be labeled "Waiver" (TODO!) and identify the version of the CTS and affected tests.
Conformance run is considered passing if all tests finish with allowed result codes. Test results are contained in the TestResults.qpa log. Each test case section contains XML tag Result, for example:
<Result StatusCode="Pass">Not validated</Result>
The result code is the value of the StatusCode attribute. Following status codes are allowed:
Pass
NotSupported
QualityWarning
CompatibilityWarning
Waiver
Submission package can be verified using verify_submission.py
script located in VK-GL-CTS-Tools.
Vulkan support from Platform implementation requires providing
getVulkanPlatform() method in tcu::Platform class implementation.
See framework/common/tcuPlatform.hpp and examples in
framework/platform/win32/tcuWin32Platform.cpp and
framework/platform/android/tcuAndroidPlatform.cpp.
If any WSI extensions are supported, platform port must also implement
methods for creating native display (vk::Platform::createWsiDisplay)
and window handles (vk::wsi::Display::createWindow). Otherwise tests
under dEQP-VK.wsi will fail.
For testing and development purposes it might be useful to be able to run
tests on dummy Vulkan implementation. One such implementation is provided in
vkNullDriver.cpp. To use that, implement vk::Platform::createLibrary() with
vk::createNullDriver().
Vulkan CTS framework includes first-party support for validation layers, that
can be turned on with --deqp-validation=enable command line option.
When validation is turned on, default instance and device will be created with validation layers enabled and debug callback is registered to record any messages. Debug messages collected during test execution will be included at the end of the test case log.
In addition, when the --deqp-print-validation-errors command line option is
used, validation errors are additionally printed to standard error in the
moment they are generated.
If any validation errors are found, test result will be set to InternalError.
By default VK_DEBUG_REPORT_INFORMATION_BIT_EXT and _DEBUG_BIT_EXT messages
are excluded from the log, but that can be customized by modifying
vk::DebugReportMessage::shouldBeLogged() in vkDebugReportUtil.hpp.
On the Android target, layers can be added to the APK during the build process
by setting the --layers-path command line option to point to the downloaded
Validation Layers binaries or a locally-built layers tree. The layers are
expected to be found under $abi/ under the layers path.
The Validation Layers releases including prebuilt binaries are available at
https://github.com/KhronosGroup/Vulkan-ValidationLayers/releases.
Vulkan test module can be used with Cherry (GUI for test execution and analysis). Cherry is available at https://android.googlesource.com/platform/external/cherry. Please follow instructions in README to get started.
Before first launch, and every time test hierarchy has been modified, test case list must be refreshed by running:
python scripts/build_caselists.py path/to/cherry/data
Cherry must be restarted for the case list update to take effect.
Vulkan CTS can be optionally run with the shader optimizer enabled. This is an experimental feature which can be used to further stress both the drivers as well as the optimizer itself. The shader optimizer is disabled by default.
The following command line options can be used to configure the shader optimizer:
--deqp-optimization-recipe=<number>
The list of the optimization recipes can be found and customized in the
optimizeCompiledBinary() function in vkPrograms.cpp.
As of this writing, there are 2 recipes to choose from:
0. Disabled (default)
1. Optimize for performance
2. Optimize for size
The performance and size optimization recipes are defined by the spir-v optimizer, and will change from time to time as the optimizer matures.
--deqp-optimize-spirv=enable
This option is not required to run the optimizer. By default, the shader optimizer only optimizes shaders generated from GLSL or HLSL, and leaves hand-written SPIR-V shaders alone.
Many of the hand-written SPIR-V tests stress specific features of the SPIR-V which might get optimized out. Using this option will enable the optimizer on the hand-written SPIR-V as well, which may be useful in finding new bugs in drivers or the optimizer itself, but will likely invalidate the tests themselves.
The Vulkan CTS framework contains a shader cache for speeding up the running of the CTS. Skipping shader compilation can significantly reduce runtime, especially for repeated runs.
Default behavior is to have the shader cache enabled, but truncated at the start of the CTS run. This still gives the benefit of skipping shader compilation for identical shaders in different tests (which there are many), while making sure that the shader cache file does not grow indefinitely.
The shader cache identifies the shaders by hashing the shader source code along with various bits of information that may affect the shader compilation (such as shader stage, CTS version, possible compilation flags, etc). If a cached shader with matching hash is found, a byte-by-byte comparison of the shader sources is made to make sure that the correct shader is being retrieved from the cache.
The behavior of the shader cache can be modified with the following command line options:
--deqp-shadercache=disable
Disable the shader cache. All shaders will be compiled every time.
--deqp-shadercache-filename=<filename>
Set the name of the file where the cached shaders will be stored. This option may be required for the shader cache to work at all on Android targets.
--deqp-shadercache-truncate=disable
Do not truncate the shader cache file at startup. No shader compilation will occur on repeated runs of the CTS.
--deqp-shadercache-ipc=enable
Enables the use of inter-process communication primitives to allow several instances of CTS to share a single cache file. All of the instances must use the same shader cache filename.
Note that if one instance should crash while holding the cache file lock, the other instances will hang. The lock is only held while reading or writing to the cache, so crashes are unlikely.
In case of a crash outside the cache file lock, the named shared memory and shared semaphore may be left behind. These will be re-used by CTS on subsequent runs, so additional memory leak will not occur. Shader cache truncate may not work in this case. On Windows, when all instances of CTS have terminated the shared resources get automatically cleaned up.
The RenderDoc (https://renderdoc.org/) graphics debugger may be used to debug Vulkan tests.
Following command line option should be used when launching tests from RenderDoc UI:
--deqp-renderdoc=enable
This causes the framework to interface with the debugger and mark each dEQP test case as a separate 'frame', just for the purpose of capturing. The frames are added using RenderDoc 'In-Application API', instead of swapchain operations.
Some CTS tests use third-party runners. By default all tests are executed
regardless of runner type (any). To exclude all tests using any of the
external runners (none) or to only include tests using a certain runner:
--deqp-runner-type=(any|none|amber)
This project is also able to perform conformance tests for Vulkan SC implementations. For this purpose Vulkan CTS framework has been adapted to Vulkan SC requirements:
-
Vulkan SC CTS contains its own mustpass list
external/vulkancts/mustpass/main/vksc-default.txt
-
Vulkan SC CTS uses its own executable module to perform tests: deqp-vksc
-
Each test in deqp-vksc is performed twice. First test run is performed in main process and its purpose is to collect information about used pipelines, number of created Vulkan objects etc. Second test run is done in separate process ( subprocess ) and it performs the real tests.
-
Vulkan SC pipelines may be compiled using offline pipeline compiler delivered by implementation vendor. You can use command line parameters to achieve this ( see parameters: --deqp-pipeline-compiler, --deqp-pipeline-dir, --deqp-pipeline-args, --deqp-pipeline-file, --deqp-pipeline-logfile, --deqp-pipeline-prefix )
Reference offline pipeline compiler was created to showcase how input and output should look like for such application. It uses Vulkan API to create pipeline cache. The name of the executable is vksc-pipeline-compiler.
-
Some of the future Vulkan SC implementations may not have a possibility to use filesystem, create pipeline caches or log results to file. For these implementations Vulkan SC CTS contains server application that may handle such requests on external host machine. Define parameter --deqp-server-address in deqp-vksc application to use external server. Server application's name is vksc-server and its parameters are listed below, in Command Line section.
