2017-09-11igt/gem_evict_(alignment,everything): Limit to low 4GChris Wilson
These tests do not tell the kernel they can use the upper 48bits of aperture space, and cause eviction on the low 4G just as effectively exercising the evict code. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Reviewed-by: Arkadiusz Hiler <arkadiusz.hiler@intel.com>

2015-10-12Replace __gem_mmap__{cpu,gtt,wc}() + igt_assert() with gem_mmap__{cpu,gtt,wc}()Ville Syrjälä
gem_mmap__{cpu,gtt,wc}() already has the assert built in, so replace __gem_mmap__{cpu,gtt,wc}() + igt_assert() with it. Mostly done with coccinelle, with some manual help: @@ identifier I; expression E1, E2, E3, E4, E5, E6; @@ ( - I = __gem_mmap__gtt(E1, E2, E3, E4); + I = gem_mmap__gtt(E1, E2, E3, E4); ... - igt_assert(I); | - I = __gem_mmap__cpu(E1, E2, E3, E4, E5); + I = gem_mmap__cpu(E1, E2, E3, E4, E5); ... - igt_assert(I); | - I = __gem_mmap__wc(E1, E2, E3, E4, E5); + I = gem_mmap__wc(E1, E2, E3, E4, E5); ... - igt_assert(I); ) Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Stochastically-reviwewed-by: Chris Wilson <chris@chris-wilson.co.uk>
2015-10-09Make gem_mmap__{cpu,gtt,wc}() assert on failureVille Syrjälä
Rename the current gem_mmap__{cpu,gtt,wc}() functions into __gem_mmap__{cpu,gtt,wc}(), and add back wrappers with the original name that assert that the pointer is valid. Most callers will expect a valid pointer and shouldn't have to bother with failures. To avoid changing anything (yet), sed 's/gem_mmap__/__gem_mmap__/g' over the entire codebase.

2015-08-21lib: add a single include headerThomas Wood
Add a header that includes all the headers for the library. This allows reorganisation of the library without affecting programs using it and also simplifies the headers that need to be included to use the library. Signed-off-by: Thomas Wood <thomas.wood@intel.com>
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>
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>

2014-11-17lib/os: Push simulation test down into intel_require_memoryDaniel Vetter
This has the upside that we'll never forget to add it to thrashing tests. But we'll also never miss to move it when adding basic functionality tests to existing binaries.

2013-11-01lib: add igt_main macroDaniel Vetter
In the past new testcases with subtest often forgot to add the call to igt_exit at the end of their main() function. That is now caught with a bit more obnoxious asserts, but it's still a nuissance. This little igt_main macro takes care of that (and also of calling the subtest machinery initialization code correctly). If no one objects I'll roll this out for all the simple cases (i.e. those tests that don't have additional argv parsing on top of the subtest machinery). v2: Roll it out across the board.

2013-09-30tests/gem_evict_everything: tune down forked subtestsDaniel Vetter
On new machines with gobloads of memory and cpu cores, but slow swap on spinning rust we need to limit the runtime a bit for sanity. Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
2013-09-03lib/drmtest: include sys/mman.h from drmtest.hDaniel Vetter

2013-08-29tests/gem_evict_everything: add swapping and forked subtestsDaniel Vetter
Much better at hitting the list corruption here on my machines than what we have thus far. Note that somehow I just can't reproduce the bug any more. No idea why. But I guess it's time to simply push this pile out. v2: Limit threads and rounds to something reasonable. v3: Use igt_permute_array to avoid EINVAL due to duplicated bo. v4: - Add a variant of the forked tests with multiple drm fds. - Tune the swapped forked tests a bit to complete in a reasonable amount of time. v5: Add some memory pressure from the cpu by using cpu mmaps (which directly hit shmem, so bypass gem completely).

2013-08-29tests/gem_evict_*: Fix leak in copyDaniel Vetter
This turned out to be the reason one one of my tests was hitting the list corruption bug - we need a good deal more memory pressure. So I'll now add a new testcase for that. Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
2013-08-23tests/gem_evict_*: Add interruptible modesDaniel Vetter
Also I've stumbled over igt_fixture again. Somehow gcc loves to wreak havoc with stack variables set up in igt_fixtures ... Duct-tape in the form of moving fd out to global scope applied. Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>

2013-08-20tests: Add gem_evict_everythingChris Wilson
Exercise the eviction logic. This is just a naive test to ensure that we can evict old buffers to accommodate new batches, and in the process trigger the evict everything logic. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
