2015-04-02igt/gem_exec_blt: Prevent assertion failure when running as a test loadChris Wilson
gem_exec_blt is used by other scripts to provide a background load, for example by drv_missed_irq. This mode doesn't act like a normal test and igt complains bitterly about it. Let's just ignore igt here. References: https://bugs.freedesktop.org/show_bug.cgi?id=88041 Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2015-04-02tests/Android.mk : skip kms_pipe_b_c_ivb if no cairoTim Gore

2015-04-02tests/gem_concurrent.c: rename to gem_concurrent_allTim Gore
Recent patch #7763349a9a87.. renamed gem_concurrent_blit.c to gem_concurrent.c and then added entries to Makefile.am to make two identical executeables (but with different names) from this source file. This executeable changes its behaviour based on argv[0]. But, this has broken the Android build, which does not use autotools. This patch instead renames the source file to match the name of one executable (gem_concurrent_all.c) and creates a second source file which simply #includes the first. The Makefile.am entries are also removed. This restores the simple test.c -> test executeable relationship seen in the rest of IGT and allows the Android build system to work without parsing Makfile.am or having to incorporate a special workaround for this test.

2015-04-02tests: install test programs to libexecJoonas Lahtinen
Install the test programs by default so that they can be packaged. Tested with the testdisplay test so that it still runs after the modifications as it depends on a data file to be present. Need to pass -r option to enable QR code display on success (PNG data file). Packaging is useful when building a complete software stack for a DUT from scratch. This should bring us closer to achieving a built-from-scratch testing workflow. Package maintainers can always decide to ignore the installed files. v2: - Install more tests including scripts and their data v3: - Add clarification to commit message about why we do this. (Chris Wilson & Thomas Wood) - Change libexec into pkglibexec to comply to standard (Thomas Wood) - Do not install $(common_files). (Thomas Wood) - Make it really obvious the installed files are tests by using tests directory name to avoid any confusion with packagers. v4: - Fixed commit message. v5: - Add file locator helper to retain backwards compatibility. (Thomas Wood) - Test with testdisplay -r option that draws the .png file.

2015-04-02igt/kms_vblank: Include a test for comparing blocking drmWaitVblankChris Wilson
The other aspect of the spinlock/interrupt on-off overhead is that when we wait for vblank it immediately turns off, and then we immediately turn it back on for the next wait. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2015-03-31tests: Add test for pipe B and C interactions in IVBAnder Conselvan de Oliveira

This reverts commit a5934091b84e3f8804fb3fed35374c5a976dd07e. Unnerf igt/gem_exec_lut_handle. Sadly completely breaking the measurement is not a good excuse to hide regressions.
2015-03-29igt/gem_evict_everything: Use mlock to reduce available memoryChris Wilson
The idea here is to check what happens when a large process requests memory from us - we create and utilize a bunch of surfaces then have to relinquish some but continue using the whole working set (so as to force reloads). Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>

Apparently nobody else likes testing and debugging GEM coherency issues. However, this also means that QA is skipping these vital tests.

2015-03-25tests/pm_sseu: Create new test pm_sseuJeff McGee
New test pm_sseu is intended for any subtest related to the slice/subslice/EU power gating feature. The sole initial subtest, 'full-enable', confirms that the slice/subslice/EU state is at full enablement when the render engine is active. Starting with Gen9 SKL, the render power gating feature can leave SSEU in a partially enabled state upon resumption of render work unless explicit action is taken. v2: Add test description and apply recommendations of igt.cocci (Thomas Wood). v3: Skip instead of fail if debugfs entry i915_sseu_status is not available.

2015-03-25tests/gem_tiled_fence_blits: split into subtestsTim Gore
The gem_tiled_fence_blits test tends to get oom killed on low memory (< 4GB) Android systems. This is because the test tries to allocate (sysinfo.totalram * 9 / 10) in buffer objects and the remaining 10% of memory is not always enough for the Android system. As with a similar issue with gem_render_linear_blits, this problem is resolved by splitting into subtests. A "basic" subtest uses minimal memory buffers to test the basic operation, and a "normal" subtest which is skipped if there is insufficient memory. I also took the opportunity to cull some numeric literals. Signed-off-by: Tim Gore <tim.gore@intel.com>

2015-03-23tests: Remove usage of igt_crc_equal and _non_nullDaniel Vetter
Tests should positively check for crc matches, not for mismatches. Enforce this by only exposing and igt_assert function for comparing crcs. For the few tests which didn't just do this as consistency checks but to do functional tests add FIXME comments that some reference crc values are missing. Signed-off-by: Daniel Vetter <daniel.vetter@intel.com>
2015-03-23lib/debugfs: Add igt_assert_crc_equalDaniel Vetter
Because of hash collisions tests should only ever compare crc checksums for equality. Checking for inequality can result in random failures. To ensure this only expose and igt_assert function and use that. Follow-up patches will rework the code for tests which don't follow this requirement and try to compare for CRC inequality. v2: Rebase on top of Matt's kms_plane changes.

2015-03-17igt/gem_concurrent_blit: Move buffer allocation after requiresChris Wilson
The choice is to either move the igt_require from the buffer allocation (and allow the allocation to fail) inside the igt_fixture, or move the buffer allocation to the subtest. Moving it to the subtest has the advantage of ensuring that every test has the same initial state (no chance of leaking state across tests) and speeding up running a single subtest. Note this is necessary in order to run igt/gem_concurrent_blit on older kernels, otherwise the requirement for mmap(wc) causes us to skip the majority of tests.
