Add forking subtests to gem_ringfill. Tests cause consistent GPU hangs on SKL.
v2: Removed noop parts. v3: - Allow executing the tests in order too (Chris Wilson). - Rename the tests to -forked-1 Cc: Mika Kuoppala <mika.kuopp...@linux.intel.com> Cc: Chris Wilson <ch...@chris-wilson.co.uk> Signed-off-by: Joonas Lahtinen <joonas.lahti...@linux.intel.com> Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=89959 --- tests/gem_ringfill.c | 91 ++++++++++++++++++++++++++++++++-------------------- 1 file changed, 57 insertions(+), 34 deletions(-) diff --git a/tests/gem_ringfill.c b/tests/gem_ringfill.c index 85b01ea..06da1c2 100644 --- a/tests/gem_ringfill.c +++ b/tests/gem_ringfill.c @@ -55,6 +55,7 @@ struct bo { }; static const int width = 512, height = 512; +int fd; static void create_bo(drm_intel_bufmgr *bufmgr, struct bo *b, @@ -193,9 +194,52 @@ static void blt_copy(struct intel_batchbuffer *batch, intel_batchbuffer_flush(batch); } -drm_intel_bufmgr *bufmgr; -struct intel_batchbuffer *batch; -int fd; +static void run_test(int ring, bool interruptible, int nchild) { + drm_intel_bufmgr *bufmgr; + struct intel_batchbuffer *batch; + igt_render_copyfunc_t copy; + const char* ring_name; + + bufmgr = drm_intel_bufmgr_gem_init(fd, 4096); + igt_require(bufmgr); + drm_intel_bufmgr_gem_enable_reuse(bufmgr); + + batch = intel_batchbuffer_alloc(bufmgr, intel_get_drm_devid(fd)); + igt_require(batch); + + if (ring == I915_EXEC_RENDER) { + copy = igt_get_render_copyfunc(batch->devid); + ring_name = "render"; + } else if (ring == I915_EXEC_BLT) { + copy = blt_copy; + ring_name = "blt"; + } else { + igt_fail_on_f(true, "Unsupported ring."); + } + + /* Not all platforms have dedicated render ring. */ + igt_require(copy); + + if (interruptible) { + igt_fork_signal_helper(); + } + + if (nchild) { + igt_fork(child, nchild) { + check_ring(bufmgr, batch, ring_name, copy); + } + igt_waitchildren(); + } else { + check_ring(bufmgr, batch, ring_name, copy); + } + + if (interruptible) { + igt_stop_signal_helper(); + } + + intel_batchbuffer_free(batch); + drm_intel_bufmgr_destroy(bufmgr); +} igt_main { @@ -203,48 +247,27 @@ igt_main igt_fixture { fd = drm_open_any(); - - bufmgr = drm_intel_bufmgr_gem_init(fd, 4096); - drm_intel_bufmgr_gem_enable_reuse(bufmgr); - batch = intel_batchbuffer_alloc(bufmgr, intel_get_drm_devid(fd)); } igt_subtest("blitter") - check_ring(bufmgr, batch, "blt", blt_copy); + run_test(I915_EXEC_BLT, false, 0); - /* Strictly only required on architectures with a separate BLT ring, - * but lets stress everybody. - */ - igt_subtest("render") { - igt_render_copyfunc_t copy; - - copy = igt_get_render_copyfunc(batch->devid); - igt_require(copy); + igt_subtest("render") + run_test(I915_EXEC_RENDER, false, 0); - check_ring(bufmgr, batch, "render", copy); - } - - igt_fork_signal_helper(); igt_subtest("blitter-interruptible") - check_ring(bufmgr, batch, "blt", blt_copy); + run_test(I915_EXEC_BLT, true, 0); - /* Strictly only required on architectures with a separate BLT ring, - * but lets stress everybody. - */ - igt_subtest("render-interruptible") { - igt_render_copyfunc_t copy; + igt_subtest("render-interruptible") + run_test(I915_EXEC_RENDER, true, 0); - copy = igt_get_render_copyfunc(batch->devid); - igt_require(copy); + igt_subtest("blitter-forked-1") + run_test(I915_EXEC_BLT, false, 1); - check_ring(bufmgr, batch, "render", copy); - } - igt_stop_signal_helper(); + igt_subtest("render-forked-1") + run_test(I915_EXEC_RENDER, false, 1); igt_fixture { - intel_batchbuffer_free(batch); - drm_intel_bufmgr_destroy(bufmgr); - close(fd); } } -- 1.8.5.5 _______________________________________________ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/intel-gfx
