2020-03-05kbuild: remove header compile testMasahiro Yamada
commit fcbb8461fd2376ba3782b5b8bd440c929b8e4980 upstream. There are both positive and negative options about this feature. At first, I thought it was a good idea, but actually Linus stated a negative opinion (https://lkml.org/lkml/2019/9/29/227). I admit it is ugly and annoying. The baseline I'd like to keep is the compile-test of uapi headers. (Otherwise, kernel developers have no way to ensure the correctness of the exported headers.) I will maintain a small build rule in usr/include/Makefile. Remove the other header test functionality.

2018-08-20drm/i915: Verify power domains after enabling themImre Deak
After commit 2cd9a689e97b ("drm/i915: Refactor intel_display_set_init_power() logic") it makes more sense to check the power domain/well refcounts after enabling the power domains functionality. Before that it's guaranteed that most power wells (in the INIT domain) will have a reference held, so not an interesting state. While at it also add the check after the init_hw/fini_hw, disable and suspend/resume steps. Make the test optional on a Kconfig option since it may add substantial overhead: on VLV/CHV the corresponding PUNIT reg access for each power well may take up to 20ms. v2: - Add the state check to more spots. (Chris) v3: - During suspend check the state before deiniting display core. Afterwards DC states are disabled (and so the dc_off power well is enabled) even though we don't hold a reference on it. - Do the test conditionally based on a new Kconfig option.

2017-12-19drm/i915: Avoid context dereference inside execlists_submission_taskletChris Wilson
A lesson that has to be relearnt over and over again is that the request does not keep a reference to the context and so we cannot freely dereference the context from inside the execlists_submission_tasklet. In particular, we try to do so in the new GEM_TRACE() so convert those over to the port->context_id we keep for GEM debugging. This means the tracing now depends on DRM_I915_GEM_DEBUG.

2017-02-13drm/i915: Provide a hook for selftestsChris Wilson
Some pieces of code are independent of hardware but are very tricky to exercise through the normal userspace ABI or via debugfs hooks. Being able to create mock unit tests and execute them through CI is vital. Start by adding a central point where we can execute unit tests and a parameter to enable them. This is disabled by default as the expectation is that these tests will occasionally explode. To facilitate integration with igt, any parameter beginning with i915.igt__ is interpreted as a subtest executable independently via igt/drv_selftest. Two classes of selftests are recognised: mock unit tests and integration tests. Mock unit tests are run as soon as the module is loaded, before the device is probed. At that point there is no driver instantiated and all hw interactions must be "mocked". This is very useful for writing universal tests to exercise code not typically run on a broad range of architectures. Alternatively, you can hook into the live selftests and run when the device has been instantiated - hw interactions are real. v2: Add a macro for compiling conditional code for mock objects inside real objects. v3: Differentiate between mock unit tests and late integration test. v4: List the tests in natural order, use igt to sort after modparam. v5: s/late/live/ v6: s/unsigned long/unsigned int/ v7: Use igt_ prefixes for long helpers. v8: Deobfuscate macros overriding functions, stop using -I$(src) Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Reviewed-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/20170213171558.20942-1-chris@chris-wilson.co.uk

2016-12-05drm/i915: Enable swfence debugobject support for i915.koChris Wilson
Only once the debugobject symbols are exported can we enable support for debugging swfences when i915 is built as a module.

2016-12-05drm/i915: Add I2C and DP-AUX char devices to debug kconfigImre Deak
These char devices exposing the driver's I2C and DP-AUX adapters for user space tools are useful to debug display output related issues. Enable them with the rest of additional driver debug options.

2016-11-25drm/i915: Integrate i915_sw_fence with debugobjectsChris Wilson
Add the tracking required to enable debugobjects for fences to improve error detection in BAT. The debugobject interface lets us track the lifetime and phases of the fences even while being embedded into larger structs, i.e. to check they are not used after they have been released. v2: Don't populate the stubs, debugobjects checks for a NULL pointer and treats it equivalently.

2016-11-08drm/i915: Enable drm_mm debug when enabling DRM_I915_DEBUGChris Wilson
A frequent issue that arises on shutdown is the drm_mm range manager complaining of a leak. To aide debugging those, drm can now track the allocation callsite and print those for the leaks.

2016-04-14drm/i915: Add GEM debugging Kconfig optionChris Wilson
Currently there is a #define to enable extra BUG_ON for debugging requests and associated activities. I want to expand its use to cover all of GEM internals (so that we can saturate the code with asserts). We can add a Kconfig option to make it easier to enable - with the usual caveats of not enabling unless explicitly requested.

2016-04-14drm/i915: Force clean compilation with -WerrorChris Wilson
Our driver compiles clean (nowadays thanks to 0day) but for me, at least, it would be beneficial if the compiler threw an error rather than a warning when it found a piece of suspect code. (I use this to compile-check patch series and want to break on the first compiler error in order to fix the patch.) v2: Kick off a new "Debugging" submenu for i915.ko At this point, we applied it to the kernel and promptly kicked it out again as it broke buildbots (due to a compiler warning on 32bits): commit 908d759b210effb33d927a8cb6603a16448474e4 Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Tue May 26 07:46:21 2015 +0200 Revert "drm/i915: Force clean compilation with -Werror" v3: Avoid enabling -Werror for allyesconfig/allmodconfig builds, using COMPILE_TEST as a suitable proxy suggested by Andrew Morton.
