These restarts can cause waterfall effects, making other tests fail in parallel, and sometimes blacklisting the test running process from executing GPU work. this results in a cascade of unrelated failures. The actual issue is unrelated to ANGLE, but rather the driver on the host systems. Submitting a large render workload (1 trillion+ points) causes the Intel GPUDriver to restart. To mitigate this issue, we can submit a smaller workload for this test, until the underlying driver bug is fixed. 1743943 1 kpiddington 2021-03-25 15:33:59 -0700 Note, these restart issues were only seen in automation on MacMini8'1, and iMac16'2 1743944 2 424287 kpiddington 2021-03-25 15:36:03 -0700 Created attachment 424287 Patch 1744051 3 dino 2021-03-25 20:20:52 -0700 Committed r275075 (235787@main): <https://commits.webkit.org/235787@main> 1744052 4 webkit-bug-importer 2021-03-25 20:21:15 -0700 <rdar://problem/75869407> 1744079 5 kkinnunen 2021-03-25 23:51:04 -0700 I think the test originally tested the thing it tried to test? If a test tests 0x40000000 to test for a bug, it's not really ok to change it to 0x1, 0x40, or 0x400000, is it? It appears that the bug that the test tests for really manifests. Would it have been better to revert this change and skip the test instead? If a test fails in other place due to a bug in implementation, we typically don't change the test... 424287 2021-03-25 15:36:03 -0700 2021-03-25 16:33:34 -0700 Patch bug-223767-20210325153602.patch text/plain 1738 kpiddington U3VidmVyc2lvbiBSZXZpc2lvbjogMjc1MDQ3CmRpZmYgLS1naXQgYS9MYXlvdXRUZXN0cy9DaGFu Z2VMb2cgYi9MYXlvdXRUZXN0cy9DaGFuZ2VMb2cKaW5kZXggZDUwY2NlMTA3MTQwOGRiNGUyMzk5 MzJkM2IwODRjODRmNDIzYTgzNi4uMTNlNjExZTc5ZWQxOTlkNmIwNmI2M2JiZjNlNzcxYmJmNDhl ZjFkMSAxMDA2NDQKLS0tIGEvTGF5b3V0VGVzdHMvQ2hhbmdlTG9nCisrKyBiL0xheW91dFRlc3Rz L0NoYW5nZUxvZwpAQCAtMSwzICsxLDE0IEBACisyMDIxLTAzLTI1ICBLeWxlIFBpZGRpbmd0b24g IDxrcGlkZGluZ3RvbkBhcHBsZS5jb20+CisKKyAgICAgICAgW01ldGFsIEFOR0xFXSBmYXN0L2Nh bnZhcy93ZWJnbC9vdXQtb2YtYm91bmRzLXNpbXVsYXRlZC12ZXJ0ZXhBdHRyaWIwLWRyYXdBcnJh eXMuaHRtbCBjYXVzZXMgR1BVUmVzdGFydHMgb24gc29tZSBtYWNoaW5lcworICAgICAgICBBdm9p ZCBHUFVSZXN0YXJ0cyBvbiBJbnRlbCBtYWNoaW5lcyBieSByZWR1Y2luZyB0ZXN0IHdvcmtsb2Fk LiBUaGUgY29yZSBvZiB0aGlzIHRlc3QsIHVzaW5nIGRlZmF1bHQgZ2VuZXJpYyBhdHRyaWJ1dGVz LCBpcyBzdGlsbCBpbiBwbGFjZS4KKworICAgICAgICBodHRwczovL2J1Z3Mud2Via2l0Lm9yZy9z aG93X2J1Zy5jZ2k/aWQ9MjIzNzY3CisKKyAgICAgICAgUmV2aWV3ZWQgYnkgTk9CT0RZIChPT1BT ISkuCisKKyAgICAgICAgKiBmYXN0L2NhbnZhcy93ZWJnbC9vdXQtb2YtYm91bmRzLXNpbXVsYXRl ZC12ZXJ0ZXhBdHRyaWIwLWRyYXdBcnJheXMuaHRtbDoKKwogMjAyMS0wMy0yNSAgSm9obiBXaWxh bmRlciAgPHdpbGFuZGVyQGFwcGxlLmNvbT4KIAogICAgICAgICBQQ006IFJlbmFtZSBhdHRyaWJ1 dGVPbiB0byBhdHRyaWJ1dGlvbkRlc3RpbmF0aW9uIGFuZCBjaGFuZ2UgdGhlIElETCBkYXRhIHR5 cGUgb2YgYXR0cmlidXRpb25Tb3VyY2VJZCB0byB1bnNpZ25lZCBsb25nCmRpZmYgLS1naXQgYS9M YXlvdXRUZXN0cy9mYXN0L2NhbnZhcy93ZWJnbC9vdXQtb2YtYm91bmRzLXNpbXVsYXRlZC12ZXJ0 ZXhBdHRyaWIwLWRyYXdBcnJheXMuaHRtbCBiL0xheW91dFRlc3RzL2Zhc3QvY2FudmFzL3dlYmds L291dC1vZi1ib3VuZHMtc2ltdWxhdGVkLXZlcnRleEF0dHJpYjAtZHJhd0FycmF5cy5odG1sCmlu ZGV4IDhhMzM0MGY2NzZmZDU5Mjc1OGMwNjExMTNkNjk3ZTM1OGQ4YzJlNzYuLmQwNDEzYjcxN2Nh ZTI2MjJhZmM1NjQ4NGQ4ZTI5Y2IyNmNkMGVmMWUgMTAwNzU1Ci0tLSBhL0xheW91dFRlc3RzL2Zh c3QvY2FudmFzL3dlYmdsL291dC1vZi1ib3VuZHMtc2ltdWxhdGVkLXZlcnRleEF0dHJpYjAtZHJh d0FycmF5cy5odG1sCisrKyBiL0xheW91dFRlc3RzL2Zhc3QvY2FudmFzL3dlYmdsL291dC1vZi1i b3VuZHMtc2ltdWxhdGVkLXZlcnRleEF0dHJpYjAtZHJhd0FycmF5cy5odG1sCkBAIC0yNyw1ICsy Nyw1IEBAIHZhciB2cyA9ICdhdHRyaWJ1dGUgdmVjMiBwb3M7IHZvaWQgbWFpbigpIHsgZ2xfUG9z aXRpb24gPSB2ZWM0KHBvcywgMCwgMSk7IH0nOwogdmFyIGZzID0gJ3ByZWNpc2lvbiBtZWRpdW1w IGZsb2F0OyB2b2lkIG1haW4oKSB7IGdsX0ZyYWdDb2xvciA9IHZlYzQoMCwwLjgsMCwxKTsgfSc7 CiB2YXIgcHJvZ3JhbSA9IGNyZWF0ZVByb2dyYW0odnMsIGZzKTsKIGdsLnVzZVByb2dyYW0ocHJv Z3JhbSk7Ci1nbC5kcmF3QXJyYXlzKDAsIDAsIDB4NDAwMDAwMDApOworZ2wuZHJhd0FycmF5cygw LCAwLCAweDQwMDAwMDApOwogPC9zY3JpcHQ+Cg==
