2015-02-13lib/igt_gt: Document and consolidateDaniel Vetter
Also move forcewake and stop_rings code from igt_debugfs to igt_gt since it fits better. And move the hang injection fork helpers from igt_aux to igt_gt, too. Also push the intel_gen call into igt_hang_ring while at it. Signed-off-by: Daniel Vetter <daniel.vetter@intel.com>
2015-02-13doc: Consolidate naming conventions into docbookDaniel Vetter
Duplication just means it gets out of sync. Also update they keyword list in the Makefile, not everything was listed. And add a new "invalid" keyword. While at it update NEWS. Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
2015-02-13tests/gem_wait: Adjust makefileDaniel Vetter
I've forgotten to do this in commit e4753d2d96fbb88077e70820793137f45f02c9ba Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Mon Sep 29 14:42:33 2014 +0200 tests/gem_wait_render_timeout: Convert to subtests Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
2015-02-13lib/igt_aux: s/swap/igt_swap/Daniel Vetter
It collides with the subtest naming convention glossary entry for swap. Which makes the docbook xml stuff unhappy. Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
2015-02-13tests: Align subtest with naming conventionDaniel Vetter
Yeah, historically grown but we should try to be somewhat consistent. It helps with filtering testcases. Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
2015-02-13tests/gem_ppgtt: Start rcs before bcs for context testsDaniel Vetter
This way the igt_require for the ctx support is hit before we've launched a bazillion threads and need to wait until they're all done. Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
2015-02-13tests: Add invalid pad tests for ctx create/destroyDaniel Vetter
We've missed them, and the kernel isn't nasty enough and forgot to check them. To add these tests convert the existing create/destroy tests over to subtests. v2: Do the basic create/destroy in ctx_bad_destroy in a fixture so that all the tests skip properly.

2015-02-13tests: Add gem_ctx_param_basicDaniel Vetter
Boring ioctl validation. Luckily no gaps found while doing it. v2: git add ftw! v3: Fixes: - args->size is an outparam for get, adjust test. - Pick an invalid param, not an invalid ioctl number ... tsk. Signed-off-by: Daniel Vetter <daniel.vetter@intel.com>

2015-02-13lib/gt: api polish for igt_can_hang_ringDaniel Vetter
Align with common igt library style: - Push the igt_require into the function. - Push the intel_gen into the function. Signed-off-by: Daniel Vetter <daniel.vetter@intel.com>
2015-02-10kms_cursor_crc: Kernel now checks for integer overflowMatt Roper
As of kernel commit commit a679064a7e9e8799177a64a31668a34a1bc6a4f1 Author: Matt Roper <matthew.d.roper@intel.com> Date: Fri Jan 30 16:22:37 2015 -0800 drm/i915: Switch planes from transitional helpers to full atomic helpers the kernel now checks for cursor coordinates that would result in integer overflow and returns -ERANGE, similar to the checking that was already done for other plane types. We update kms_cursor_crc here to reflect this small behavior change: * Check for success at extreme boundary conditions INT_MAX-{width,height} rather than INT_MAX * Add new check for success at SHRT_MAX; if the driver were to internally use short values and overflow, we could have the cursor reappear on the screen. * Add a test for failure with proper error code at INT_MAX-{width,height}+1 Signed-off-by: Matt Roper <matthew.d.roper@intel.com>

It was possible for invalidate range start mmu notifier callback to race with releasing userptr object.

2015-01-29tests/prime_self_import: further fix object countsThomas Daniel
A previous commit: commit 2f2c491cf3167befe7c79e4b17afb4f6284dfc84 Author: Mika Kuoppala <mika.kuoppala@intel.com> Date: Fri Mar 28 10:52:46 2014 +0200 lib/drmtest: don't dup quiescent fd introduced a regression for drm object leak checking. A following commit: commit 8741c2289f17e9bcb740a01cad4764a71c918eea Author: Mika Kuoppala <mika.kuoppala@intel.com> Date: Wed May 7 16:46:19 2014 +0300 tests/gem_flink_race,prime_self_import: fix object counts fixed the regression for some cases but missed the export-vs-gem_close-race subtest. Note that test behaviour depends on whether the subtest is run as part of the whole prime_self_import test (fail), or as a single subtest (pass). Using execlists on Gen8+ reverses the pass/fail due to lazy context allocation which is presumably why this has now been noticed. This commit applies the same fix to the export-vs-gem_close-race subtest.

2015-01-07igt/gem_concurrent_blit: Inject hangs before verifying contentsChris Wilson
After setting up the copy operations, add a hanging batch. This should mean that we complete the copy and the compare then races against the GEM reset. Hopefully, this will catch driver bugs where the target object is no longer accessible after the hang. Note: hang injection is disabled until the required kernel interface is completed.

2015-01-06igt/gem_tiled_wc: Exercise wc mmaps with swizzlingChris Wilson
This exercises both the wc mmappings and the extended get_tiling ioctl. Userspace cannot handle bit17 swizzling through wc mmaps (because bit17 requires swizzling based on the actual physical address of the page - which is unknown to userspace) and so we need an extended get_tiling ioctl to report the actual as well as the logical swizzling on an object. We then check that the contents of the object are tiled and swizzled correctly when viewed through a wc mmap.
