Execute IGT test manually (no timeout is used): ./gem_mmap_gtt --r swap-copy 2. Wait 100 hours Actual results: ---------------- 2. Test is still not finished after 100 hours (IGT is still running - DUT is not freezed) dmesg shows the same logs on all platforms, example on SKL: [ 151.322722] [IGT] gem_mmap_gtt: executing [ 151.353973] [IGT] gem_mmap_gtt: starting subtest swap-copy [ 151.354090] gem_mmap_gtt (31952): drop_caches: 4 [ 4843.205005] perf: interrupt took too long (2540 > 2500), lowering kernel.perf_event_max_sample_rate to 78500 [ 6383.794279] perf: interrupt took too long (3202 > 3175), lowering kernel.perf_event_max_sample_rate to 62250 [ 9271.093175] perf: interrupt took too long (4037 > 4002), lowering kernel.perf_event_max_sample_rate to 49500 [14046.280647] perf: interrupt took too long (5090 > 5046), lowering kernel.perf_event_max_sample_rate to 39250 [22889.758381] perf: interrupt took too long (6365 > 6362), lowering kernel.perf_event_max_sample_rate to 31250 [50315.915256] perf: interrupt took too long (7982 > 7956), lowering kernel.perf_event_max_sample_rate to 25000 Expected results: ----------------- 2. Test is not so long Info: ----- I can't attach dmesg due to its size There is no log from IGT
