Re: Fedora 30 drm error

[Rodrigo Vivi <rodrigo.vivi@intel.com>]

Hi Chunyu,

First of all sorry for the delay on the response here.
Many of us were out on vacation and holidays.

Also in general please use https://bugs.freedesktop.org/
to report bugs.

Please make sure you read this before:
https://01.org/linuxgraphics/documentation/how-report-bugs

Best way to find out if we have had a fix for that is to try out drm-tip:

https://cgit.freedesktop.org/drm-tip/

Recently we had many patches touching watermarks and other related areas
that usually are known for FIFO underruns.

Another good reason to try drm-tip. And if that is fixed on drm-tip and
you need to find the exact patch that fixed the issue you need to perform
a reversed bisect.

It seems yet another issue to be reported at bugzilla.freedesktop.org
And also to check reproduciablitity with drm-tip...

Thanks,
Rodrigo.
