1 This is a collection of tools for development and testing of the Intel DRM
2 driver. There are many macro-level test suites that get used against our
3 driver, including xtest, rendercheck, piglit, and oglconform, but failures
4 from those can be difficult to track down to kernel changes, and many require
5 complicated build procedures or specific testing environments to get useful
8 Thus, intel-graphics-tools was a project I started to collect some low-level
9 tools I intended to build.
12 This should be a collection of useful microbenchmarks. The hope is
13 that people can use these to tune some pieces of DRM code in relevant
16 The benchmarks require KMS to be enabled. When run with an X Server
17 running, they must be run as root to avoid the authentication
20 Note that a few other microbenchmarks are in tests (like gem_gtt_speed).
23 This is a set of automated tests to run against the DRM to validate
24 changes. Hopefully this can cover the relevant cases we need to
25 worry about, including backwards compatibility.
27 Note: The old automake based testrunner had to be scraped due to
28 upstream changes which broke dynamic creation of the test list. Of
29 course it is still possible to directly run tests, even when not always
30 limiting tests to specific subtests (like piglit does).
32 The more comfortable way to run tests is with piglit. First grab piglit
35 git://anongit.freedesktop.org/piglit
37 and build it (no need to install anything). Then we need to link up the
38 i-g-t sources with piglit
40 piglit-sources $ cd bin
41 piglit-sources/bin $ ln $i-g-t-sources igt -s
43 The tests in the i-g-t sources need to have been built already. Then we
44 can run the testcases with (as usual as root, no other drm clients
47 piglit-sources # ./piglit-run.py tests/igt.tests <results-file>
49 The testlist is built at runtime, so no need to update anything in
50 piglit when adding new tests. See
52 piglit-sources $ ./piglit-run.py -h
54 for some useful options.
56 Piglit only runs a default set of tests and is useful for regression
57 testing. Other tests not run are:
58 - tests that might hang the gpu, see HANG in Makefile.am
59 - gem_stress, a stress test suite. Look at the source for all the
61 - testdisplay is only run in the default mode. testdisplay has tons of
62 options to test different kms functionality, again read the source for
65 When creating new tests or subtests please read and follow
66 tests/NAMING-CONVENTION.
69 Common helper functions and headers used by the other tools.
72 Manpages, unfortunately rather incomplete.
75 This is a collection of debugging tools that had previously been
76 built with the 2D driver but not shipped. Some distros were hacking
77 up the 2D build to ship them. Instead, here's a separate package for
78 people debugging the driver.
80 These tools generally must be run as root, safe for the ones that just
84 Quick dumper is a python tool built with SWIG bindings to
85 important libraries exported by the rest of the tool suite. The tool
86 itself is quite straight forward, and should also be a useful example
87 for others wishing to write python based i915 tools.
89 Note to package maintainers: It is not recommended to package
90 this directory, as the tool is not yet designed for wide usage. If the
91 package is installed via "make install" the users will have to set
92 their python library path appropriately. Use --disable-dumper
95 This tool is to be used to do shader debugging. It acts like a
96 debug server accepting connections from debug clients such as
97 mesa. The connections is made with unix domain sockets, and at some
98 point it would be nice if this directory contained a library for
99 initiating connections with debug clients..
101 The debugger must be run as root: "sudo debugger/eudb"
