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 NOTE: glslang integration is not yet available on Android due to a toolchain
49 bug, so pre-compiled SPIR-V binaries must be used. See instructions below.
51 With CMake out-of-source builds are always recommended. Create a build directory
52 of your choosing, and in that directory generate Makefiles or IDE project
58 cmake <path to vulkancts> -G"Visual Studio 12"
59 start dEQP-Core-default.sln
63 cmake <path to vulkancts> -G"Visual Studio 12 Win64"
64 start dEQP-Core-default.sln
66 ### Linux 32-bit Debug
68 cmake <path to vulkancts> -DCMAKE_BUILD_TYPE=Debug -DCMAKE_C_FLAGS=-m32 -DCMAKE_CXX_FLAGS=-m32
71 Release build can be done by using -DCMAKE_BUILD_TYPE=Release
73 ### Linux 64-bit Debug
75 cmake <path to vulkancts> -DCMAKE_BUILD_TYPE=Debug -DCMAKE_C_FLAGS=-m64 -DCMAKE_CXX_FLAGS=-m64
80 Following command will build CTS into android/package/bin/dEQP-debug.apk.
82 python android/scripts/build.py
84 The package can be installed by either running:
86 python android/scripts/install.py
88 By default the CTS package will contain libdeqp.so built for armeabi-v7a, arm64-v8a,
89 and x86 ABIs, but that can be changed in android/scripts/common.py script.
91 To pick which ABI to use at install time, following commands must be used
94 adb install --abi <ABI name> android/package/bin/dEQP-debug.apk /data/local/tmp/dEQP-debug.apk
100 Current mustpass is checked into repository and can be found at:
102 external/vulkancts/mustpass/1.0.0/vk-default.txt
104 Vulkan CTS mustpass can be re-generated by running:
106 python <vulkancts>/external/vulkancts/build_mustpass.py
109 Pre-compiling SPIR-V binaries
110 -----------------------------
112 For distribution, and platforms that don't support GLSL to SPIR-V compilation,
113 SPIR-V binaries must be pre-built with following command:
115 python external/vulkancts/build_spirv_binaries.py
117 Binaries will be written to `external/vulkancts/data/vulkan/prebuilt/`.
119 Test modules (or in case of Android, the APK) must be re-built after building
120 SPIR-V programs in order for the binaries to be available.
126 Following command line options MUST be used when running CTS:
128 --deqp-caselist-file=<vulkancts>/external/vulkancts/mustpass/1.0.0/vk-default.txt
129 --deqp-log-images=disable
130 --deqp-log-shader-sources=disable
132 In addition on multi-device systems the device for which conformance is claimed
133 can be selected with:
135 --deqp-vk-device-id=<value>
137 To speed up the conformance run on some platforms the following command line
138 option may be used to disable frequent fflush() calls to the output logs:
140 --deqp-log-flush=disable
142 No other command line options are allowed.
146 cd <builddir>/external/vulkancts/modules/vulkan
147 Debug/deqp-vk.exe --deqp-caselist-file=...
149 Test log will be written into TestResults.qpa
153 cd <builddir>/external/vulkancts/modules/vulkan
154 ./deqp-vk --deqp-vk-caselist-file=...
158 adb push <vulkancts>/external/vulkancts/mustpass/1.0.0/vk-default.txt /sdcard/vk-default.txt
163 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"
165 Test progress will be written to device log and can be displayed with:
169 Test log will be written into `/sdcard/TestResults.qpa`.
172 Conformance Submission Package Requirements
173 -------------------------------------------
175 The conformance submission package must contain the following:
177 1. Full test logs (`TestResults.qpa`) from CTS runs against all driver builds
178 2. Result of `git status` and `git log` from CTS source directory
179 3. Any patches used on top of release tag
180 4. Conformance statement
182 Test logs (1) should be named `<submission pkg dir>/TestResults-<driver build type>.qpa`,
183 for example `TestResults-armeabi-v7a.qpa`. On platforms where multiple different driver
184 builds (for example 64-bit and 32-bit) are present, CTS logs must be provided
185 for each driver build as part of the submission package.
187 The CTS build must always be done from clean git repository that doesn't have any
188 uncommitted changes. Thus it is necessary to run and capture output of `git
189 status` and `git log` (2) in the source directory:
191 git status > <submission pkg dir>/git-status.txt
192 git log <release tag>..HEAD > <submission pkg dir>/git-log.txt
194 Any changes made to CTS must be committed to the local repository, and provided
195 as part of the submission package (3). This can be done by running:
197 git format-patch -o <submission pkg dir> <release tag>..HEAD
199 In general, bugfixes and changes to platform-specific code (mostly under
200 `framework/platform`) are allowed. The commit message for each change must
201 include a clear description of the change and why it is necessary. Non-porting
202 related changes must be accompanied by a waiver (see below).
204 NOTE: When cherry-picking patches on top of release tag, please use `git cherry-pick -x`
205 to include original commit hash in the commit message.
207 Conformance statement (4) must be included in a file called `STATEMENT-<adopter>`
208 and must contain following:
210 CONFORM_VERSION: <git tag of CTS release>
211 PRODUCT: <string-value>
215 Note that product/cpu/os information is also captured in `dEQP-VK.info.*` tests
216 if `vk::Platform::describePlatform()` is implemented.
218 If the submission package covers multiple products, you can list them by appending
219 additional `PRODUCT:` lines to the conformance statement. For example:
221 CONFORM_VERSION: vulkan-cts-1.0.0-internal
226 The actual submission package consists of the above set of files which must
227 be bundled into a gzipped tar file named `VK10_<adopter><_info>.tgz`. `<adopter>`
228 is the name of the Adopting member company, or some recognizable abbreviation.
229 The `<_info>` field is optional. It may be used to uniquely identify a submission
230 by OS, platform, date, or other criteria when making multiple submissions.
232 One way to create a suiteable gzipped tar file is to execute the command:
234 tar -cvzf <filename.tgz> -C <submission pkg dir> .
236 where `<submission pkg dir>` is the directory containing the files from (1)-(4)
237 from above. A submission package must contain all of the files listed above,
238 and only those files.
240 As an example submission package could contain:
245 0001-Remove-Waived-Filtering-Tests.patch
246 0002-Fix-Pipeline-Parameters.patch
247 TestResults-armeabi-v7a.qpa
248 TestResults-arm64-v8a.qpa
254 The process for requesting a waiver is to report the issue by filing a bug
255 report in the Gitlab VulkanCTS project (TODO Github?). When creating the
256 submission package, include references to the waiver in the commit message of
257 the relevant change. Including as much information as possible in your bug
258 report (including a unified diff or a merge request of suggested file changes)
259 will ensure the issue can be progressed as rapidly as possible. Issues must
260 be labeled "Waiver" (TODO!) and identify the version of the CTS and affected
266 Conformance run is considered passing if all tests finish with allowed result
267 codes. Test results are contained in the TestResults.qpa log. Each
268 test case section contains XML tag Result, for example:
270 <Result StatusCode="Pass">Not validated</Result>
272 The result code is the value of the StatusCode attribute. Following status
280 Submission package can be verified using `external/vulkancts/verify_submission.py`
281 script. The script takes two arguments: path to extracted submission package
282 and path to current mustpass list. For example:
284 python external/vulkancts/verify_submission.py VK_10_Khronos_1/ external/vulkancts/mustpass/1.0.0/vk-default.txt
290 Vulkan support from Platform implementation requires providing
291 `getVulkanPlatform()` method in `tcu::Platform` class implementation.
293 See `framework/common/tcuPlatform.hpp` and examples in
294 `framework/platform/win32/tcuWin32Platform.cpp` and
295 `framework/platform/android/tcuAndroidPlatform.cpp`.
301 For testing and development purposes it might be useful to be able to run
302 tests on dummy Vulkan implementation. One such implementation is provided in
303 vkNullDriver.cpp. To use that, implement `vk::Platform::createLibrary()` with
304 `vk::createNullDriver()`.
310 Vulkan CTS framework includes first-party support for validation layers, that
311 can be turned on with `--deqp-validation=enable` command line option.
313 When validation is turned on, default instance and device will be created with
314 validation layers enabled and debug callback is registered to record any
315 messages. Debug messages collected during test execution will be included at
316 the end of the test case log.
318 If any validation errors are found, test result will be set to `InternalError`.
320 By default `VK_DEBUG_REPORT_INFORMATION_BIT_EXT` and `_DEBUG_BIT_EXT` messages
321 are excluded from the log, but that can be customized by modifying
322 `vkt::TestCaseExecutor::deinit()` in `vktTestPackage.cpp`.
328 Vulkan test module can be used with Cherry (GUI for test execution and
329 analysis). Cherry is available at
330 https://android.googlesource.com/platform/external/cherry. Please follow
331 instructions in README to get started.
333 To enable support for Vulkan tests, dEQP-VK module must be added to list of
336 In `cherry/testrunner.go`, add following line to `testPackageDescriptors` list
337 (line 645 in `NewTestRunner` function):
339 {"dEQP-VK", "deqp-vk", "../external/vulkancts/modules/vulkan", dataDir + "dEQP-VK-cases.xml"},
341 Before first launch, and every time test hierarchy has been modified, test
342 case list must be refreshed by running:
344 python scripts/build_caselists.py path/to/cherry/data
346 Cherry must be restarted for the case list update to take effect.
