Comment 2 Chris Wilson 2019-04-05 19:57:09 UTC

Just another example of icl randomly being super slow. At this point I am suspecting that the GPU really does slow down to <100MHz.

Comment 3 Francesco Balestrieri 2019-04-11 08:14:54 UTC

The recently merged RPS fixes may or may not help here (although odds are mostly against). Let's see if this improves in any way.

Comment 4 Jani Saarinen 2019-04-22 15:37:27 UTC

There has been BIOS fixes fixing irq storms that could help here too.

Comment 5 Jani Saarinen 2019-04-22 15:38:03 UTC

Also seen once ~3 weeks ago, proposing drop priority.

Comment 6 Francesco Balestrieri 2019-06-03 05:27:26 UTC

Seen once in two months, there is hope that some of the many ICL fixes helped - closing.

Comment 7 Lakshmi 2019-08-13 13:40:51 UTC

Still no occurrences after CI_DRM_5873_full (4 months, 1 week old). Closing and archiving the issue.
