From fa3bfa3527b31562dba28d49c0a18b722b42e226 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Thu, 29 Oct 2020 21:30:42 +0000 Subject: [PATCH] drm: Quieten [zero] EDID carping MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit We have a few displays in CI that always report their EDID as a bunch of zeroes. This is consistent behaviour, so one assumes intentional indication of an "absent" EDID. Flagging these consistent warnings detracts from CI. One option would be to ignore the zero EDIDs as intentional behaviour, but Ville would like to keep the information available for debugging. The simple alternative then is to reduce the loglevel for all the EDID dumping from WARN to DEBUG so the information is present but not annoy CI. Note that the bad EDID dumping is already only shown if drm.debug=KMS, it's just the loglevel chosen was set to be caught by CI if it ever occurred as it was expected to be an internal error not external.
