Comment 2 Jani Saarinen 2019-05-22 14:46:03 UTC
According to Imre this one is a bug in the test itself leading to the SIGSEGV. Something in the Chamelium RPC call. So not an issue the driver.
Comment 3 Lakshmi 2019-05-31 11:37:24 UTC
Moving to IGT to fix the test.
Comment 4 Lakshmi 2019-05-31 11:37:36 UTC
Moving to IGT to fix the test.
Comment 5 Maarten Lankhorst 2019-06-05 10:29:56 UTC
Hmm seems like an error in the chamelium wrappers. Specifically the call to pthread_cancel seems to be crashing. Need to figure out why, but shouldn't affect real users as this happens in the chamelium code.
Comment 6 emersion 2019-06-05 10:44:54 UTC
Agreed that this is an IGT bug, not a driver bug.

Just sent an IGT patch that attempts to fix the issue.

User impact: the user might experience corrupted frames via HDMI. In other words: we don't check anymore that HDMI is properly working since this test is broken.

Other CRC/frame tests aren't run after a crash (this is the first one).

This bug has only been seen once, 4 weeks ago.
Comment 8 emersion 2019-07-02 13:31:52 UTC
Not seen for a month and a half. Still happened just once.

Let's just close it, and re-open if it happens again.
Comment 9 swathi.dhanavanthri 2019-11-22 23:52:01 UTC
Not seen on drm tip, so closing and archiving this.
