4 This document describes how to build and run Vulkan Conformance Test suite.
6 Vulkan CTS is built on dEQP framework. dEQP documentation is available
7 at http://source.android.com/devices/graphics/testing.html
15 * Git (for checking out sources)
16 * Python 2.7.x (all recent versions in 2.x should work, 3.x is not supported)
21 * Visual Studio 2013 or newer (glslang uses several C++11 features)
25 * Standard toolchain (make, gcc/clang)
30 * Android SDK with: SDK Tools, SDK Platform-tools, SDK Build-tools, and API 22
31 * Java Development Kit (JDK)
33 * Windows: either NMake or JOM in PATH
35 See `android/scripts/common.py` for a list locations where the build system
36 expects to find these.
42 To build dEQP, you need first to download sources for zlib, libpng, glslang,
45 To download sources, run:
47 python external/fetch_sources.py
49 You may need to re-run `fetch_sources.py` to update to the latest glslang and
50 spirv-tools revisions occasionally.
52 With CMake out-of-source builds are always recommended. Create a build directory
53 of your choosing, and in that directory generate Makefiles or IDE project
59 cmake <path to vulkancts> -G"Visual Studio 12"
60 start dEQP-Core-default.sln
64 cmake <path to vulkancts> -G"Visual Studio 12 Win64"
65 start dEQP-Core-default.sln
67 ### Linux 32-bit Debug
69 cmake <path to vulkancts> -DCMAKE_BUILD_TYPE=Debug -DCMAKE_C_FLAGS=-m32 -DCMAKE_CXX_FLAGS=-m32
72 Release build can be done by using -DCMAKE_BUILD_TYPE=Release
74 ### Linux 64-bit Debug
76 cmake <path to vulkancts> -DCMAKE_BUILD_TYPE=Debug -DCMAKE_C_FLAGS=-m64 -DCMAKE_CXX_FLAGS=-m64
81 Following command will build CTS into android/package/bin/dEQP-debug.apk.
83 python android/scripts/build.py
85 The package can be installed by either running:
87 python android/scripts/install.py
89 By default the CTS package will contain libdeqp.so built for armeabi-v7a, arm64-v8a,
90 and x86 ABIs, but that can be changed in android/scripts/common.py script.
92 To pick which ABI to use at install time, following commands must be used
95 adb install --abi <ABI name> android/package/bin/dEQP-debug.apk /data/local/tmp/dEQP-debug.apk
101 Current mustpass is checked into repository and can be found at:
103 external/vulkancts/mustpass/1.0.1/vk-default.txt
105 Vulkan CTS mustpass can be re-generated by running:
107 python <vulkancts>/external/vulkancts/build_mustpass.py
110 Pre-compiling SPIR-V binaries
111 -----------------------------
113 For distribution, and platforms that don't support GLSL to SPIR-V compilation,
114 SPIR-V binaries can be pre-built with following command:
116 python external/vulkancts/build_spirv_binaries.py
118 Binaries will be written to `external/vulkancts/data/vulkan/prebuilt/`.
120 Test modules (or in case of Android, the APK) must be re-built after building
121 SPIR-V programs in order for the binaries to be available.
127 Following command line options MUST be used when running CTS:
129 --deqp-caselist-file=<vulkancts>/external/vulkancts/mustpass/1.0.1/vk-default.txt
130 --deqp-log-images=disable
131 --deqp-log-shader-sources=disable
133 In addition on multi-device systems the device for which conformance is claimed
134 can be selected with:
136 --deqp-vk-device-id=<value>
138 To speed up the conformance run on some platforms the following command line
139 option may be used to disable frequent fflush() calls to the output logs:
141 --deqp-log-flush=disable
143 No other command line options are allowed.
147 cd <builddir>/external/vulkancts/modules/vulkan
148 Debug/deqp-vk.exe --deqp-caselist-file=...
150 Test log will be written into TestResults.qpa
154 cd <builddir>/external/vulkancts/modules/vulkan
155 ./deqp-vk --deqp-vk-caselist-file=...
159 adb push <vulkancts>/external/vulkancts/mustpass/1.0.1/vk-default.txt /sdcard/vk-default.txt
164 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"
166 Test progress will be written to device log and can be displayed with:
170 Test log will be written into `/sdcard/TestResults.qpa`.
173 Conformance Submission Package Requirements
174 -------------------------------------------
176 The conformance submission package must contain the following:
178 1. Full test logs (`TestResults.qpa`) from CTS runs against all driver builds
179 2. Result of `git status` and `git log` from CTS source directory
180 3. Any patches used on top of release tag
181 4. Conformance statement
183 Test logs (1) should be named `<submission pkg dir>/TestResults-<driver build type>.qpa`,
184 for example `TestResults-armeabi-v7a.qpa`. On platforms where multiple different driver
185 builds (for example 64-bit and 32-bit) are present, CTS logs must be provided
186 for each driver build as part of the submission package.
188 The CTS build must always be done from clean git repository that doesn't have any
189 uncommitted changes. Thus it is necessary to run and capture output of `git
190 status` and `git log` (2) in the source directory:
192 git status > <submission pkg dir>/git-status.txt
193 git log --first-parent <release tag>^..HEAD > <submission pkg dir>/git-log.txt
195 Any changes made to CTS must be committed to the local repository, and provided
196 as part of the submission package (3). This can be done by running:
198 git format-patch -o <submission pkg dir> <release tag>..HEAD
200 In general, bugfixes and changes to platform-specific code (mostly under
201 `framework/platform`) are allowed. The commit message for each change must
202 include a clear description of the change and why it is necessary. Non-porting
203 related changes must be accompanied by a waiver (see below).
205 NOTE: When cherry-picking patches on top of release tag, please use `git cherry-pick -x`
206 to include original commit hash in the commit message.
208 Conformance statement (4) must be included in a file called `STATEMENT-<adopter>`
209 and must contain following:
211 CONFORM_VERSION: <git tag of CTS release>
212 PRODUCT: <string-value>
216 Note that product/cpu/os information is also captured in `dEQP-VK.info.*` tests
217 if `vk::Platform::describePlatform()` is implemented.
219 If the submission package covers multiple products, you can list them by appending
220 additional `PRODUCT:` lines to the conformance statement. For example:
222 CONFORM_VERSION: vulkan-cts-1.0.1.0
227 The actual submission package consists of the above set of files which must
228 be bundled into a gzipped tar file named `VK10_<adopter><_info>.tgz`. `<adopter>`
229 is the name of the Adopting member company, or some recognizable abbreviation.
230 The `<_info>` field is optional. It may be used to uniquely identify a submission
231 by OS, platform, date, or other criteria when making multiple submissions.
233 One way to create a suiteable gzipped tar file is to execute the command:
235 tar -cvzf <filename.tgz> -C <submission pkg dir> .
237 where `<submission pkg dir>` is the directory containing the files from (1)-(4)
238 from above. A submission package must contain all of the files listed above,
239 and only those files.
241 As an example submission package could contain:
246 0001-Remove-Waived-Filtering-Tests.patch
247 0002-Fix-Pipeline-Parameters.patch
248 TestResults-armeabi-v7a.qpa
249 TestResults-arm64-v8a.qpa
255 The process for requesting a waiver is to report the issue by filing a bug
256 report in the Gitlab VulkanCTS project (TODO Github?). When creating the
257 submission package, include references to the waiver in the commit message of
258 the relevant change. Including as much information as possible in your bug
259 report (including a unified diff or a merge request of suggested file changes)
260 will ensure the issue can be progressed as rapidly as possible. Issues must
261 be labeled "Waiver" (TODO!) and identify the version of the CTS and affected
267 Conformance run is considered passing if all tests finish with allowed result
268 codes. Test results are contained in the TestResults.qpa log. Each
269 test case section contains XML tag Result, for example:
271 <Result StatusCode="Pass">Not validated</Result>
273 The result code is the value of the StatusCode attribute. Following status
281 Submission package can be verified using `external/vulkancts/verify_submission.py`
282 script. The script takes two arguments: path to extracted submission package
283 and path to current mustpass list. For example:
285 python external/vulkancts/verify_submission.py VK_10_Khronos_1/ external/vulkancts/mustpass/1.0.1/vk-default.txt
291 Vulkan support from Platform implementation requires providing
292 `getVulkanPlatform()` method in `tcu::Platform` class implementation.
294 See `framework/common/tcuPlatform.hpp` and examples in
295 `framework/platform/win32/tcuWin32Platform.cpp` and
296 `framework/platform/android/tcuAndroidPlatform.cpp`.
298 If any WSI extensions are supported, platform port must also implement
299 methods for creating native display (`vk::Platform::createWsiDisplay`)
300 and window handles (`vk::wsi::Display::createWindow`). Otherwise tests
301 under `dEQP-VK.wsi` will fail.
307 For testing and development purposes it might be useful to be able to run
308 tests on dummy Vulkan implementation. One such implementation is provided in
309 vkNullDriver.cpp. To use that, implement `vk::Platform::createLibrary()` with
310 `vk::createNullDriver()`.
316 Vulkan CTS framework includes first-party support for validation layers, that
317 can be turned on with `--deqp-validation=enable` command line option.
319 When validation is turned on, default instance and device will be created with
320 validation layers enabled and debug callback is registered to record any
321 messages. Debug messages collected during test execution will be included at
322 the end of the test case log.
324 If any validation errors are found, test result will be set to `InternalError`.
326 By default `VK_DEBUG_REPORT_INFORMATION_BIT_EXT` and `_DEBUG_BIT_EXT` messages
327 are excluded from the log, but that can be customized by modifying
328 `vkt::TestCaseExecutor::deinit()` in `vktTestPackage.cpp`.
334 Vulkan test module can be used with Cherry (GUI for test execution and
335 analysis). Cherry is available at
336 https://android.googlesource.com/platform/external/cherry. Please follow
337 instructions in README to get started.
339 Before first launch, and every time test hierarchy has been modified, test
340 case list must be refreshed by running:
342 python scripts/build_caselists.py path/to/cherry/data
344 Cherry must be restarted for the case list update to take effect.
