IGT GPU Tools

Description

IGT GPU Tools is a collection of tools for development and testing of the DRM drivers. There are many macro-level test suites that get used against the drivers, including xtest, rendercheck, piglit, and oglconform, but failures from those can be difficult to track down to kernel changes, and many require complicated build procedures or specific testing environments to get useful results. Therefore, IGT GPU Tools includes low-level tools and tests specifically for development and testing of the DRM Drivers.

IGT GPU Tools is split into several sections:

benchmarks/

This is a collection of useful microbenchmarks that can be used to tune DRM code in relevant ways.

The benchmarks require KMS to be enabled. When run with an X Server running, they must be run as root to avoid the authentication requirement.

Note that a few other microbenchmarks are in tests (like gem_gtt_speed).

tests/

This is a set of automated tests to run against the DRM to validate changes. Many of the tests have subtests, which can be listed by using the --list-subtests command line option and then run using the --run-subtest option. If --run-subtest is not used, all subtests will be run. Some tests have futher options and these are detailed by using the --help option.

The test suite can be run using the run-tests.sh script available in the scripts directory. Piglit is used to run the tests and can either be installed from your distribution (if available), or can be downloaded locally for use with the script by running:

./scripts/run-tests.sh -d

run-tests.sh has options for filtering and excluding tests from test runs:

-t only include tests that match the regular expression -x exclude tests that match the regular expression

Useful patterns for test filtering are described in the API documentation and the full list of tests and subtests can be produced by passing -l to the run-tests.sh script.

Results are written to a JSON file and an HTML summary can also be created by passing -s to the run-tests.sh script. Further options are are detailed by using the -h option.

If not using the script, piglit can be obtained from:

git://anongit.freedesktop.org/piglit

There is no need to build and install piglit if it is only going to be used for running i-g-t tests.

Set the IGT_TEST_ROOT environment variable to point to the tests directory, or set the path key in the “igt” section of piglit.conf to the igt-gpu-tools root directory.

The tests in the i-g-t sources need to have been built already. Then we can run the testcases with (as usual as root, no other drm clients running):

piglit-sources # ./piglit run igt <results-file>

The testlist is built at runtime, so no need to update anything in piglit when adding new tests. See

piglit-sources $ ./piglit run -h

for some useful options.

Piglit only runs a default set of tests and is useful for regression testing. Other tests not run are:

  • tests that might hang the gpu, see HANG in Makefile.am
  • gem_stress, a stress test suite. Look at the source for all the various options.
  • testdisplay is only run in the default mode. testdisplay has tons of options to test different kms functionality, again read the source for the details.

lib/

Common helper functions and headers used by the other tools.

man/

Manpages, unfortunately rather incomplete.

tools/

This is a collection of debugging tools that had previously been built with the 2D driver but not shipped. Some distros were hacking up the 2D build to ship them. Instead, here's a separate package for people debugging the driver.

These tools generally must be run as root, except for the ones that just decode dumps.

docs/

Contains the automatically generated igt-gpu-tools libraries reference documentation in docs/reference/. You need to have the gtk-doc tools installed and use the “--enable-gtk-doc” configure flag to generate this API documentation.

To regenerate the html files when updating documentation, use:

$ ninja -C build igt-gpu-tools-doc

If you've added/changed/removed a symbol or anything else that changes the overall structure or indexes, this needs to be reflected in igt-gpu-tools-sections.txt. Entirely new sections will also need to be added to igt-gpu-tools-docs.xml in the appropriate place.

include/drm-uapi

Imported DRM uapi headers from airlied‘s drm-next branch. These should be updated all together by executing “make headers_install” from that branch of the kernel and then copying the resulting ./usr/include/drm/*.h in and committing with a note of which commit on airlied’s branch was used to generate them.

Requirements

This is a non-exhaustive list of package dependencies required for building the default configuration (package names may vary):

gtk-doc-tools
libcairo2-dev
libdrm-dev
libkmod-dev
libpixman-1-dev
libpciaccess-dev
libprocps-dev
libunwind-dev
liblzma-dev
libdw-dev
python-docutils
x11proto-dri2-dev
xutils-dev

The following dependencies are required for building chamelium support (package names may vary):

libxmlrpc-core-c3-dev
libudev-dev
libglib2.0-dev
libgsl-dev

The following dependencies are requires for building audio support (package names may vary):

libasound2-dev
libgsl-dev

See Dockerfiles.* for package names in different distributions.

Meson build system support

Currently we support both meson and automake as build systems, but meson is the recommended choice. Oneliner to get started:

$ mkdir build && meson build && cd build && ninja

Note that meson insist on separate build directories from the source tree.

Running selfchecks for lib/tests and tests/ is done with

$ ninja -C build test

Note that this doesn't actually run the testcases in tests/: scripts/run-tests.sh should continue to be used for that.

Documentation is built using

$ ninja -C build igt-gpu-tools-doc

Note that this needs meson v0.47 or later, earlier versions of meson do not track depencies correctly for the documentation build and need:

$ ninja -C build && ninja -C build igt-gpu-tools-doc

Note that there's a setup script similar to ./autogen.sh which creates a compatibility Makefile with a few useful default targets:

$ ./meson.sh [make-arguments]
