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
32 * Windows: either NMake or JOM in PATH
38 To build dEQP, you need first to download sources for zlib, libpng, glslang,
41 To download sources, run:
43 python external/fetch_sources.py
45 You may need to re-run `fetch_sources.py` to update to the latest glslang and
46 spirv-tools revisions occasionally.
48 With CMake out-of-source builds are always recommended. Create a build directory
49 of your choosing, and in that directory generate Makefiles or IDE project
55 cmake <path to vulkancts> -G"Visual Studio 12"
56 start dEQP-Core-default.sln
60 cmake <path to vulkancts> -G"Visual Studio 12 Win64"
61 start dEQP-Core-default.sln
63 ### Linux 32-bit Debug
65 cmake <path to vulkancts> -DCMAKE_BUILD_TYPE=Debug -DCMAKE_C_FLAGS=-m32 -DCMAKE_CXX_FLAGS=-m32
68 Release build can be done by using -DCMAKE_BUILD_TYPE=Release
70 ### Linux 64-bit Debug
72 cmake <path to vulkancts> -DCMAKE_BUILD_TYPE=Debug -DCMAKE_C_FLAGS=-m64 -DCMAKE_CXX_FLAGS=-m64
77 Following command will build CTS into android/package/bin/dEQP-debug.apk.
79 python android/scripts/build.py
81 The package can be installed by either running:
83 python android/scripts/install.py
85 By default the CTS package will contain libdeqp.so built for armeabi-v7a, arm64-v8a,
86 and x86 ABIs, but that can be changed in android/scripts/common.py script.
88 To pick which ABI to use at install time, following commands must be used
91 adb install --abi <ABI name> android/package/bin/dEQP-debug.apk /data/local/tmp/dEQP-debug.apk
97 Current mustpass is checked into repository and can be found at:
99 external/vulkancts/mustpass/1.0.1/vk-default.txt
101 Vulkan CTS mustpass can be re-generated by running:
103 python <vulkancts>/external/vulkancts/build_mustpass.py
106 Pre-compiling SPIR-V binaries
107 -----------------------------
109 For distribution, and platforms that don't support GLSL to SPIR-V compilation,
110 SPIR-V binaries can be pre-built with following command:
112 python external/vulkancts/build_spirv_binaries.py
114 Binaries will be written to `external/vulkancts/data/vulkan/prebuilt/`.
116 Test modules (or in case of Android, the APK) must be re-built after building
117 SPIR-V programs in order for the binaries to be available.
123 Following command line options MUST be used when running CTS:
125 --deqp-caselist-file=<vulkancts>/external/vulkancts/mustpass/1.0.1/vk-default.txt
126 --deqp-log-images=disable
127 --deqp-log-shader-sources=disable
129 In addition on multi-device systems the device for which conformance is claimed
130 can be selected with:
132 --deqp-vk-device-id=<value>
134 To speed up the conformance run on some platforms the following command line
135 option may be used to disable frequent fflush() calls to the output logs:
137 --deqp-log-flush=disable
139 No other command line options are allowed.
143 cd <builddir>/external/vulkancts/modules/vulkan
144 Debug/deqp-vk.exe --deqp-caselist-file=...
146 Test log will be written into TestResults.qpa
150 cd <builddir>/external/vulkancts/modules/vulkan
151 ./deqp-vk --deqp-vk-caselist-file=...
155 adb push <vulkancts>/external/vulkancts/mustpass/1.0.1/vk-default.txt /sdcard/vk-default.txt
160 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"
162 Test progress will be written to device log and can be displayed with:
166 Test log will be written into `/sdcard/TestResults.qpa`.
169 Conformance Submission Package Requirements
170 -------------------------------------------
172 The conformance submission package must contain the following:
174 1. Full test logs (`TestResults.qpa`) from CTS runs against all driver builds
175 2. Result of `git status` and `git log` from CTS source directory
176 3. Any patches used on top of release tag
177 4. Conformance statement
179 Test logs (1) should be named `<submission pkg dir>/TestResults-<driver build type>.qpa`,
180 for example `TestResults-armeabi-v7a.qpa`. On platforms where multiple different driver
181 builds (for example 64-bit and 32-bit) are present, CTS logs must be provided
182 for each driver build as part of the submission package.
184 The CTS build must always be done from clean git repository that doesn't have any
185 uncommitted changes. Thus it is necessary to run and capture output of `git
186 status` and `git log` (2) in the source directory:
188 git status > <submission pkg dir>/git-status.txt
189 git log --first-parent <release tag>^..HEAD > <submission pkg dir>/git-log.txt
191 Any changes made to CTS must be committed to the local repository, and provided
192 as part of the submission package (3). This can be done by running:
194 git format-patch -o <submission pkg dir> <release tag>..HEAD
196 In general, bugfixes and changes to platform-specific code (mostly under
197 `framework/platform`) are allowed. The commit message for each change must
198 include a clear description of the change and why it is necessary. Non-porting
199 related changes must be accompanied by a waiver (see below).
201 NOTE: When cherry-picking patches on top of release tag, please use `git cherry-pick -x`
202 to include original commit hash in the commit message.
204 Conformance statement (4) must be included in a file called `STATEMENT-<adopter>`
205 and must contain following:
207 CONFORM_VERSION: <git tag of CTS release>
208 PRODUCT: <string-value>
212 Note that product/cpu/os information is also captured in `dEQP-VK.info.*` tests
213 if `vk::Platform::describePlatform()` is implemented.
215 If the submission package covers multiple products, you can list them by appending
216 additional `PRODUCT:` lines to the conformance statement. For example:
218 CONFORM_VERSION: vulkan-cts-1.0.1.0
223 The actual submission package consists of the above set of files which must
224 be bundled into a gzipped tar file named `VK10_<adopter><_info>.tgz`. `<adopter>`
225 is the name of the Adopting member company, or some recognizable abbreviation.
226 The `<_info>` field is optional. It may be used to uniquely identify a submission
227 by OS, platform, date, or other criteria when making multiple submissions.
229 One way to create a suiteable gzipped tar file is to execute the command:
231 tar -cvzf <filename.tgz> -C <submission pkg dir> .
233 where `<submission pkg dir>` is the directory containing the files from (1)-(4)
234 from above. A submission package must contain all of the files listed above,
235 and only those files.
237 As an example submission package could contain:
242 0001-Remove-Waived-Filtering-Tests.patch
243 0002-Fix-Pipeline-Parameters.patch
244 TestResults-armeabi-v7a.qpa
245 TestResults-arm64-v8a.qpa
251 The process for requesting a waiver is to report the issue by filing a bug
252 report in the Gitlab VulkanCTS project (TODO Github?). When creating the
253 submission package, include references to the waiver in the commit message of
254 the relevant change. Including as much information as possible in your bug
255 report (including a unified diff or a merge request of suggested file changes)
256 will ensure the issue can be progressed as rapidly as possible. Issues must
257 be labeled "Waiver" (TODO!) and identify the version of the CTS and affected
263 Conformance run is considered passing if all tests finish with allowed result
264 codes. Test results are contained in the TestResults.qpa log. Each
265 test case section contains XML tag Result, for example:
267 <Result StatusCode="Pass">Not validated</Result>
269 The result code is the value of the StatusCode attribute. Following status
277 Submission package can be verified using `external/vulkancts/verify_submission.py`
278 script. The script takes two arguments: path to extracted submission package
279 and path to current mustpass list. For example:
281 python external/vulkancts/verify_submission.py VK_10_Khronos_1/ external/vulkancts/mustpass/1.0.1/vk-default.txt
287 Vulkan support from Platform implementation requires providing
288 `getVulkanPlatform()` method in `tcu::Platform` class implementation.
290 See `framework/common/tcuPlatform.hpp` and examples in
291 `framework/platform/win32/tcuWin32Platform.cpp` and
292 `framework/platform/android/tcuAndroidPlatform.cpp`.
294 If any WSI extensions are supported, platform port must also implement
295 methods for creating native display (`vk::Platform::createWsiDisplay`)
296 and window handles (`vk::wsi::Display::createWindow`). Otherwise tests
297 under `dEQP-VK.wsi` will fail.
303 For testing and development purposes it might be useful to be able to run
304 tests on dummy Vulkan implementation. One such implementation is provided in
305 vkNullDriver.cpp. To use that, implement `vk::Platform::createLibrary()` with
306 `vk::createNullDriver()`.
312 Vulkan CTS framework includes first-party support for validation layers, that
313 can be turned on with `--deqp-validation=enable` command line option.
315 When validation is turned on, default instance and device will be created with
316 validation layers enabled and debug callback is registered to record any
317 messages. Debug messages collected during test execution will be included at
318 the end of the test case log.
320 If any validation errors are found, test result will be set to `InternalError`.
322 By default `VK_DEBUG_REPORT_INFORMATION_BIT_EXT` and `_DEBUG_BIT_EXT` messages
323 are excluded from the log, but that can be customized by modifying
324 `vkt::TestCaseExecutor::deinit()` in `vktTestPackage.cpp`.
330 Vulkan test module can be used with Cherry (GUI for test execution and
331 analysis). Cherry is available at
332 https://android.googlesource.com/platform/external/cherry. Please follow
333 instructions in README to get started.
335 Before first launch, and every time test hierarchy has been modified, test
336 case list must be refreshed by running:
338 python scripts/build_caselists.py path/to/cherry/data
340 Cherry must be restarted for the case list update to take effect.
