Release 1.11 (2015-06-11)
-------------------------

- Various new tests and tools

- Single combined test list (supported by piglit since commit 8a122bb)

- Optional dependency on libunwind to provide automatic stack traces on test
  failures. (Thomas Wood)

- Add optional default debug and optimisation flags for tests to enable better
  stack traces and debugging. (Thomas Wood)

- Test programs are now installed into libexec. This is useful when building a
  complete software stack for a DUT from scratch. (Building and installing
  tests can still be disabled by the --disable-tests configure flag.)
  (Joonas Lahtinen)

- New tool to decode watermark registers (Ville Syrjälä)

- Timeout mechanism now reports test as failed

- Introduce intel_reg as the one Intel graphics register multitool to replace
  intel_reg_read, intel_reg_write, intel_iosf_sb_read, intel_iosf_sb_write,
  intel_vga_read, intel_vga_write, intel_reg_dumper, intel_reg_snapshot,
  and quick_dump.py. (Jani Nikula)

- Add functions to manipulate i915.ko parameters and ensure features are enabled
  for testing. (Paulo Zanoni)

Release 1.10 (2015-03-12)
-------------------------

- New frequency manipulation tool (intel_gpu_frequency)

- Adjustments for the Solaris port (Alan Coopersmith).

- Remove tests/NAMING-CONVENTION since it's all in the docbook now, to avoid
  divergent conventions.

- New CRITICAL log level for really serious stuff (Thomas Wood).

- Interactive test mode can now be enabled by the shared cmdline option
  --interactive-debug=$var (Rodrigo Vivi).

- Improved logging to kmsg to better line up test runs with kernel messages
  (Chris Wilson).

- Record all log levels (including disabled levels) in a ringbuffer and dump
  that on test failures for quicker diagnostics of automated test run results
  (Thomas Wood).

- A lot of small polish all over the test library.

- Piles of new testcases and improvements to existing ones as usual.

Release 1.9 (2014-12-12)
------------------------

- New test cases added: drm_import_export, gem_gpgpu_fill, gem_ppgtt,
  gem_tiled_wb, kms_pwrite_crc.

- New helper for interactive progress indicators (see igt_print_activity and
  igt_progress), which can be disabled by setting the log-level to warn (Thomas
  and Daniel).

- Basic skl support: pci ids, rendercopy & mediafill (Damien, Zhao Yakui).

- chv support for the iosf sideband tools and a few other improvements (Ville).

- Fence register support for intel_reg_dumper on bdw+ (Rodrigo).

- Support for skl in quick_dump (Damien).

- Golden state generation infrastructure (Mika).

- New skl watermark tool (Damien).

- New EDID test block that includes multiple display modes (Thomas).

- Individual test documentation available in generated documentation and from
  the test binaries (Thomas).

- New logging domains and log filtering (Thomas).

- Various API documentation fixes and improvements (Thomas).

Release 1.8 (2014-09-08)
------------------------

- Added lib/igt.cocci semantic patch to catch often-seen patterns and convert
  them to igt macros/infrastructure.

- Improvements to the documentation build systems (Thomas).

- Small fixes and improvements to the igt infrastructure and helpers all over.

- As usual piles of new tests.

- Improved plane/pipe handling in the igt_kms library (Damien).

- Unified option parsing between simple tests and tests with subtests (Thomas).
  This will allow us to merge the different Makefile targets once test runners
  are converted.

- New commit functions for igt_kms to support the new universal planes
  interfaces (Matt Roper).

- Polish the debug output when test requirements aren't met a bit and inject the
  program name/subtest in dmesg for easier backtrace/oom debugging (Chris).

- A bit of polish for the framebuffer helper functions (Damien).

- Robuster option parsing helpers, they now check for conflicts when merging
  different option lists (Thomas).

- MIPI DSI vbt support in intel_bios_read (Gaurav K Singh).

- Clarify the split between low-level helpers and the high-level library in
  igt_kms a bit by renaming some functions and improving and extending the api
  documentation.

- Helper to restore the vt mode, useful to test lastclose/fbdev emulation
  behaviour (Thomas).

- Refactor the support for 64bit relocs. By specifying the number of relocations
  explicit a lot of the gen8 checks can be removed from simple testcases which
  only use the blitter (Chris).

Release 1.7 (2014-06-09)
------------------------

- Piles of API documentation for the core i-g-t testing libraries.

- Improved igt loggin, now also with igt_vlog (for va_args printf-style
  logging).

- Polish for the igt_debugfs library.

- Split out igt_fb library from igt_kms, cleanup of the igt_kms functions.

- Android porting patches (Tim Gore, Tvrtko Ursulin).

- Piles more tests as usual.

- Support for building libcairo based tests on Android. Set ANDROID_HAS_CAIRO=1
  in the build enviroment when you have this (Tim Gore).

- Timeout support in igt_aux, see igt_set_timeout (Thomas).

- Documentation for the testrunner interface like exit codes, subtest
  enumeration and log output. Should help other people to run the tests in their
  own framework.

- Make swig an optional dependency (Damien).

- Helpers for runtime pm tests in igt_aux.

Release 1.6 (2014-03-13)
------------------------

- Changes to support Broadwell in the test suite. (Ben, Damien, et al.)

- Updated (now working again!) Android support from Oscar Mateo.

- Test coverage through i-g-t is now officially an integral part of any drm/i915
  feature work and also for bugfixes. For more details see:

  http://blog.ffwll.ch/2013/11/testing-requirements-for-drmi915.html

- Fix the gen4asm build dependency handling, now that the assembler is included in
  i-g-t (Ben).

- Improve the cairo object lifetime management of the kmstest helpers (Chris).

- Allow register access to succeed if i915 is loaded but debugfs isn't found
  (i.e. nomodeset is used)

- New kernel modesetting helper library for simpler testcases (Damien).

- New structure logging support for tests. Message at the WARN level be
  reflected in the piglit result, also included igt_warn_on macros to simplify
  test asserts which should just result in warnings, but not in a test abort.

- Broadwell support for intel_audio_dump (Mengdong Lin).

- API documentation support (Thomas)

Release 1.5 (2013-11-06)
------------------------

- Some polishing of the test infrastructure, for details see:

  http://blog.ffwll.ch/2013/09/more-drmi915-testsuite-infrastructure.html

- Haswell support for the DPF tool (tools/intel_l3_parity) and other
  improvements (Ben).

- Support for gen7 gpu perf counters in tools/intel_perf_counters (Kenneth).

- Improvements to the VBT decoder (Jani).

- New tool to read legacy VGA registers (Ville).

- New helpers in the test library to help deal with debugfs files and the new
  display pipe CRC support (Damien).

- Introduction of a proper naming convention for all the testcases, see
  tests/NAMING-CONVENTION.

- As usual tons of new testcases and improvements and bugfixes to existing ones.

- The testsuite framework itself has gained some regression tests which can be
  run at compile-time with "make check".

- New helpers for the drop_cache kernel interface and use drop_caches(RETIRE) to
  really make sure the gpu is idle in testcases (Oscar Mateo).

Release 1.4 (2013-09-16)
------------------------

- Integration of the gen4+ assembler (Damien).

- Start of a new performance analysis tool from Chris Wilson with front-ends for
  both X11 and plain kms. This uses the perf subsystem and the gpu performance
  counter kernel patches from Chris.

- New register dumper quick_dump from Ben, with lots of work from Damien. This
  will superseed intel_reg_dumper for newer platforms (which are not yet
  released) since it will allow us to automatically generate register dumps from
  the internal xml register specifications.

- Tools to access the pletoria of new indirect register access functions on
  newer platforms.

- Framebuffer contents dumper to debug some of the nastier corruption issues.
  The advantage here is that this bypasses any userspace drivers and so avoids
  that the corruptions get magically fixed when taking an X screenshot.

- Tons of new testcases. Including subtests we are now at roughly 450 tests!

- Improvements to the test framework infrastructure. See
  http://blog.ffwll.ch/2013/08/recent-drmi915-testsuite-improvements.html
  for an overview.

- buildsystem improvements (Gaetan Nadon)
- solaris support (Alan Coopersmith)
- massive refactoring of testcases and rendercpy extraction
- new tests
- fixed up intel_reg_read/write for platforms needing forcewake (needs a
  kernel patch which from 3.3 to work on ivb - Ben Widawsky)

Release 1.1 (2011-12-24)
------------------------

Improved testsuite, usable for kernel regression testing!

Release 1.0 (2009-04-27)
------------------------

- standalone regression tests for the DRM (make check)
- microbenchmarks of the DRM for kernel performance regression testing
