1 Release 1.7 (XXXX-XX-XX)
2 ------------------------
4 - Piles of API documentation for the core i-g-t testing libraries.
6 Release 1.6 (2014-03-13)
7 ------------------------
9 - Changes to support Broadwell in the test suite. (Ben, Damien, et al.)
11 - Updated (now working again!) Android support from Oscar Mateo.
13 - Test coverage through i-g-t is now officially an integral part of any drm/i915
14 feature work and also for bugfixes. For more details see:
16 http://blog.ffwll.ch/2013/11/testing-requirements-for-drmi915.html
18 - Fix the gen4asm build dependency handling, now that the assembler is included in
21 - Improve the cairo object lifetime management of the kmstest helpers (Chris).
23 - Allow register access to succeed if i915 is loaded but debugfs isn't found
24 (i.e. nomodeset is used)
26 - New kernel modesetting helper library for simpler testcases (Damien).
28 - New structure logging support for tests. Message at the WARN level be
29 reflected in the piglit result, also included igt_warn_on macros to simplify
30 test asserts which should just result in warnings, but not in a test abort.
32 - Broadwell support for intel_audio_dump (Mengdong Lin).
34 - API documentation support (Thomas)
36 Release 1.5 (2013-11-06)
37 ------------------------
39 - Some polishing of the test infrastructure, for details see:
41 http://blog.ffwll.ch/2013/09/more-drmi915-testsuite-infrastructure.html
43 - Haswell support for the DPF tool (tools/intel_l3_parity) and other
46 - Stereo/3D support in testdisplay (Damien).
48 - Support for gen7 gpu perf counters in tools/intel_perf_counters (Kenneth).
50 - Improvements to the VBT decoder (Jani).
52 - New tool to read legacy VGA registers (Ville).
54 - New helpers in the test library to help deal with debugfs files and the new
55 display pipe CRC support (Damien).
57 - Introduction of a proper naming convention for all the testcases, see
58 tests/NAMING-CONVENTION.
60 - As usual tons of new testcases and improvements and bugfixes to existing ones.
62 - The testsuite framework itself has gained some regression tests which can be
63 run at compile-time with "make check".
65 - New helpers for the drop_cache kernel interface and use drop_caches(RETIRE) to
66 really make sure the gpu is idle in testcases (Oscar Mateo).
68 Release 1.4 (2013-09-16)
69 ------------------------
71 - Integration of the gen4+ assembler (Damien).
73 - Start of a new performance analysis tool from Chris Wilson with front-ends for
74 both X11 and plain kms. This uses the perf subsystem and the gpu performance
75 counter kernel patches from Chris.
77 - New register dumper quick_dump from Ben, with lots of work from Damien. This
78 will superseed intel_reg_dumper for newer platforms (which are not yet
79 released) since it will allow us to automatically generate register dumps from
80 the internal xml register specifications.
82 - Tools to access the pletoria of new indirect register access functions on
85 - Framebuffer contents dumper to debug some of the nastier corruption issues.
86 The advantage here is that this bypasses any userspace drivers and so avoids
87 that the corruptions get magically fixed when taking an X screenshot.
89 - Tons of new testcases. Including subtests we are now at roughly 450 tests!
91 - Improvements to the test framework infrastructure. See
92 http://blog.ffwll.ch/2013/08/recent-drmi915-testsuite-improvements.html
95 Release 1.3 (2012-08-27)
96 ------------------------
98 - massive improvements to the testsuite
99 - dpf tool for handling l3 remapping on gen7 (Ben)
100 - robustify against wc gtt mappings (Chris)
101 - improvements to the reg_dumper and register read/write tools
104 Release 1.2 (2012-02-09)
105 ------------------------
107 - intel_audio_dump improvements (Wu Fengguang)
108 - buildsystem improvements (Gaetan Nadon)
109 - solaris support (Alan Coopersmith)
110 - massive refactoring of testcases and rendercpy extraction
112 - fixed up intel_reg_read/write for platforms needing forcewake (needs a
113 kernel patch which from 3.3 to work on ivb - Ben Widawsky)
115 Release 1.1 (2011-12-24)
116 ------------------------
118 Improved testsuite, usable for kernel regression testing!
120 Release 1.0 (2009-04-27)
121 ------------------------
124 - miscellaneous userland tools that don't really fit into the 2D driver tree
125 - standalone regression tests for the DRM (make check)
126 - microbenchmarks of the DRM for kernel performance regression testing
