2013-09-10lib/drmtest: consolidate the helper process killing in one exit handlerfor-imreDaniel Vetter2-9/+38
Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
2013-09-10tests/gem_reloc_vs_gpu: use igt_fork_helperDaniel Vetter1-13/+3
Now we do a waitpid instead of a simple wait which could eat the "wrong" child ... Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
2013-09-10lib/drmtest: create helpers for forking helper threadsDaniel Vetter2-28/+61
The upshot is that we can share the logic to make sure the helpers are all properly stoved again in a 2nd step. Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>

2013-09-08lib/drmtest: Avoid calling exit handlers multiple timesDaniel Vetter1-2/+16
- reset the count when forking - don't add the same handler multiple times - don't restore the exit signal handlers in the forked helper process - reset the exit handler count once called to make sure we don't call it multiple times when dying - don't wait for the signal helper if it's gone already Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>

Fix the regression introduced in commit bfbe813f8fb587017c4e1d73c51395c2837eb395 Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Tue May 29 22:14:06 2012 +0200 lib: fix gen5 workaround emission Signed-off-by: Imre Deak <imre.deak@intel.com>

2013-09-04tests/gem_pipe_control_store_loop: Add subtest for reused buffersDaniel Vetter1-45/+56
This exercises the slightly faulty kernel w/a that Eric fixed in commit e844b990b1df9242bb91b7d490552f3198946838 Author: Eric Anholt <eric@anholt.net> Date: Tue Jul 31 15:35:01 2012 -0700 drm/i915: Don't forget to apply SNB PIPE_CONTROL GTT workaround. If a buffer that was the target of a PIPE_CONTROL from userland was a reused one that hadn't been evicted which had not previously had this workaround applied, then the early return for a correct presumed_offset in this function meant we would not bind it into the GTT and the write would land somewhere else. Fixes reproducible failures with GL_EXT_timer_query usage in apitrace, and I also expect it to fix the intermittent OQ issues on snb that danvet's been working on.

2013-09-03intel_gtt: Properly support gen6+ GTT PTEsBen Widawsky1-8/+34
This finishes the objective in the last patch which was to actually deal with physical addresses, and not the PTEs. GEN6+ Provided support for physical addresses above 4GB. I'm not actually sure what Ironlake supported, and don't feel like firing up the timemachine. v2: Add support for gen4, gen5, and haswell. Signed-off-by: Ben Widawsky <ben@bwidawsk.net>
2013-09-03intel_gtt: Use function to get the physical addressBen Widawsky1-11/+15
The GTT PTEs that the tool is trying to compare is really about addresses, and not the PTE itself. To accomplish this, make which calculates the physical address we actually want. This commit itself doesn't change any functionality; just the wording in the code. Signed-off-by: Ben Widawsky <ben@bwidawsk.net>
2013-09-03gem_vmap_blits: Demote warning to noteBen Widawsky1-1/+1
The warning that vmap isn't supported is useful, but it shouldn't get in the way of developers (or distros) being able to use -Werror. Cc: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Ben Widawsky <ben@bwidawsk.net>

2013-09-02kms_flip: Fix use of fb_width for PAN subtestsChris Wilson1-10/+7
We need to be careful to remember that fb-width is not always the same as hdisplay, since for panning we allocate a larger framebuffer. So fix up the printfs to use hdisplay/vsisplay since that should be uniform across the array.

2013-08-29tests/gem_evict_everything: add swapping and forked subtestsDaniel Vetter1-9/+157
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 Vetter2-0/+2
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>

2013-08-29lib/drmtest: extract igt_fork from gem_concurrent_bltDaniel Vetter3-34/+103
Making sure that we correctly collect the exit codes from all children is a bit a hassle. So add another magic igt codeblock for easy forking and joining. Note that children are (currently at least) not allowed to call igt_skip. Add an assert to enforce this. v2: - Properly propagate the exit code. - Fix the segfault. - Add a child int and num_children paramter to the magic codeblock as suggested by Chris Wilson. - Don't dump noise into stdout when a child thread fails, the parent will do that for us already. v3: Now with some docs. v4: Fixup igt_waitchildren to properly reset state so it can be used again.

2013-08-29kms_flip: Use the first mode if we find no matching modes for the crtc pairChris Wilson1-1/+5

2013-08-29kms_flip: Run on pairs of connected outputs.Chris Wilson1-13/+209
The goal is to flip the same framebuffer on a pair of CRTCs (clone mode) and check that (a) the flip works in all combinations of workloads, and (b) that we can hit the desired refresh rate under the simplest, most ideal of conditions. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2013-08-29kms_flips: Operate on an array of crtcChris Wilson1-55/+79
This should be no functional change as we operate on an array of crtc[1]. Later we shall test clone mode across a number of crtc. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2013-08-29kms_flip: Exercise flip-vs-renderChris Wilson4-32/+103
For machine with split BCS/RCS rings, we also need to test whether we correctly wait upon outstanding render work before flipping and changing modes. This should also serve to exercise the ring selection code for flips. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
