Random WebGL 2.0 conformance failures on Mac Intel |
||||||||||||||||||||||
Issue descriptionRandom WebGL 2.0 conformance failures are being seen on the Mac Intel bots. The failures are all over the place. On these two consecutive builds: https://build.chromium.org/p/chromium.gpu.fyi/builders/Mac%20Release%20%28Intel%29/builds/1697 https://build.chromium.org/p/chromium.gpu.fyi/builders/Mac%20Release%20%28Intel%29/builds/1698 the following failures were seen: WebglConformance_conformance2_textures_canvas_tex_2d_srgb8_rgb_unsigned_byte WebglConformance_conformance2_textures_misc_integer_cubemap_texture_sampling WebglConformance_deqp_functional_gles3_transformfeedback_array_interleaved_points WebglConformance_deqp_functional_gles3_transformfeedback_basic_types_interleaved_points WebglConformance_deqp_functional_gles3_transformfeedback_random_separate_points and: WebglConformance_deqp_functional_gles3_fbomultisample_4_samples WebglConformance_deqp_functional_gles3_shadertexturefunction_texturelod WebglConformance_deqp_functional_gles3_transformfeedback_basic_types_separate_points Failures are seen here: https://build.chromium.org/p/chromium.gpu.fyi/builders/Mac%20Release%20(Intel) and on the associated bot on the V8 waterfall: https://build.chromium.org/p/client.v8.fyi/builders/Mac%20Release%20%28Intel%29?numbuilds=200 The tests were running reliably up till about March 24, when a regression crept in that turned the bots red for a weekend ( Issue 705156 ). Then the tests started flaking not long afterward. It does look like there might be at least one hardware failure: https://chromium-swarm.appspot.com/bot?id=build603-m4&sort_stats=total%3Adesc looks like it's returning 0x0 for the GPU vendor and device ID. I'm taking it out of the Swarming pool and have filed Issue 707473 about it. John, since you're pixel wrangler next week could you triage some of the other failures and see whether they seem to be a similar failure mode? Thanks.

We're also seeing this issue on the ASAN bot: https://luci-logdog.appspot.com/v/?s=chromium%2Fbb%2Fchromium.gpu.fyi%2FMac_GPU_ASAN_Release%2F2238%2F%2B%2Frecipes%2Fsteps%2Fwebgl2_conformance_tests_on_Intel_GPU_on_Mac_on_Mac-10.12%2F0%2Fstdout ==10709==ERROR: AddressSanitizer: SEGV on unknown address 0xffffffffffffffd8 (pc 0x7fffb37e1195 bp 0x700003661080 sp 0x700003661078 T4) ==10709==The signal is caused by a READ memory access. ==10709==WARNING: invalid path to external symbolizer! ==10709==WARNING: Failed to use and restart external symbolizer! #0 0x7fffb37e1194 in libunwind::CompactUnwinder_x86_64<libunwind::LocalAddressSpace>::stepWithCompactEncodingRBPFrame(unsigned int, unsigned long long, libunwind::LocalAddressSpace&, libunwind::Registers_x86_64&) (/usr/lib/system/libunwind.dylib:x86_64+0x1194) #1 0x7fffb37e10d0 in libunwind::UnwindCursor<libunwind::LocalAddressSpace, libunwind::Registers_x86_64>::step() (/usr/lib/system/libunwind.dylib:x86_64+0x10d0) #2 0x10d09329f in bool base::(anonymous namespace)::WalkStackFromContext<base::(anonymous namespace)::NativeStackSamplerMac::SuspendThreadAndRecordStack(base::StackSamplingProfiler::Sample*)::$_0>(unw_context_t*, unsigned long*, base::(anonymous namespace)::NativeStackSamplerMac::SuspendThreadAndRecordStack(base::StackSamplingProfiler::Sample*)::$_0 const&) (/b/s/w/irwENaSa/out/Release/Chromium.app/Contents/Versions/59.0.3062.0/Chromium Framework.framework/Versions/A/Chromium Framework:x86_64+0x651d29f) #3 0x10d09222f in base::(anonymous namespace)::NativeStackSamplerMac::RecordStackSample(base::StackSamplingProfiler::Sample*) (/b/s/w/irwENaSa/out/Release/Chromium.app/Contents/Versions/59.0.3062.0/Chromium Framework.framework/Versions/A/Chromium Framework:x86_64+0x651c22f) #4 0x10d095f88 in base::StackSamplingProfiler::SamplingThread::CollectProfile(base::StackSamplingProfiler::CallStackProfile*, base::TimeDelta*, bool*) (/b/s/w/irwENaSa/out/Release/Chromium.app/Contents/Versions/59.0.3062.0/Chromium Framework.framework/Versions/A/Chromium Framework:x86_64+0x651ff88) #5 0x10d095608 in base::StackSamplingProfiler::SamplingThread::CollectProfiles(std::__1::vector<base::StackSamplingProfiler::CallStackProfile, std::__1::allocator<base::StackSamplingProfiler::CallStackProfile> >*) (/b/s/w/irwENaSa/out/Release/Chromium.app/Contents/Versions/59.0.3062.0/Chromium Framework.framework/Versions/A/Chromium Framework:x86_64+0x651f608) #6 0x10d095018 in base::StackSamplingProfiler::SamplingThread::ThreadMain() (/b/s/w/irwENaSa/out/Release/Chromium.app/Contents/Versions/59.0.3062.0/Chromium Framework.framework/Versions/A/Chromium Framework:x86_64+0x651f018) #7 0x10d12d91d in base::(anonymous namespace)::ThreadFunc(void*) (/b/s/w/irwENaSa/out/Release/Chromium.app/Contents/Versions/59.0.3062.0/Chromium Framework.framework/Versions/A/Chromium Framework:x86_64+0x65b791d) #8 0x7fffb37a9aaa in _pthread_body (/usr/lib/system/libsystem_pthread.dylib:x86_64+0x3aaa) #9 0x7fffb37a99f6 in _pthread_start (/usr/lib/system/libsystem_pthread.dylib:x86_64+0x39f6) #10 0x7fffb37a91fc in thread_start (/usr/lib/system/libsystem_pthread.dylib:x86_64+0x31fc)
