Hi all,
I noticed that the drm cmdline EDID override mechanisms no longer work since Linux version 4.15.
My monitor lost its VGA EDID a long time ago, so I retrieved a copy of it from backups of Xorg logs and I have to use the Linux kernel's EDID override mechanisms. In order to get the right mode early in boot, I use the Linux kernel cmdline option for this and put the required firmware file into the initramfs so my cryptsetup prompt is right:
drm_kms_helper.edid_firmware=VGA-1:edid/VGA-1
Linux 4.15 deprecates this option:
kernel: [drm] drm_kms_firmware.edid_firmware is deprecated, please use drm.edid_firmware intead.
So I switched to the new option:
drm.edid_firmware=VGA-1:edid/VGA-1
This did not produce any warnings or errors in dmesg but also did not result in the EDID override file being applied.
I added both the override options to the Linux kernel command-line in grub and this did not work in the newer versions of Linux.
I also tried this without the VGA-1: connector specifier and this did not improve the situation but did prevent the LVDS screen from working:
drm.edid_firmware=edid/VGA-1 drm_kms_helper.edid_firmware=edid/VGA-1
I tested the Debian Linux kernel builds on snapshot.debian.org and version 4.15~rc5-1~exp1 came up as the first broken one.
I confirmed that overrides do not work with the latest Linux kernel version in Debian buster (4.17.8-1).
I then git bisected the issue and came up with 53fd40a90f3c as bad. I also checked that the following commit ac6c35a4d8c7 was also bad.

53fd40a90f3c0bdad86ec266ee5df833f54ace39 is the first bad commit commit 53fd40a90f3c0bdad86ec266ee5df833f54ace39 Author: Jani Nikula jani.nikula@intel.com Date: Tue Sep 12 11:19:26 2017 +0300
drm: handle override and firmware EDID at drm_do_get_edid() level
Handle debugfs override edid and firmware edid at the low level to transparently and completely replace the real edid. Previously, we practically only used the modes from the override EDID, and none of the other data, such as audio parameters.
This change also prevents actual EDID reads when the EDID is to be overridden, but retains the DDC probe. This is useful if the reason for preferring override EDID are problems with reading the data, or corruption of the data.
Move firmware EDID loading from helper to core, as the functionality moves to lower level as well. This will result in a change of module parameter from drm_kms_helper.edid_firmware to drm.edid_firmware, which arguably makes more sense anyway.
Some future work remains related to override and firmware EDID validation. Like before, no validation is done for override EDID. The firmware EDID is validated separately in the loader. Some unification and deduplication would be in order, to validate all of them at the drm_do_get_edid() level, like "real" EDIDs.
v2: move firmware loading to core
v3: rebase, commit message refresh

drm: add backwards compatibility support for drm_kms_helper.edid_firmware
Add drm_kms_helper.edid_firmware module parameter with param ops hooks to set drm.edid_firmware instead, for backwards compatibility.
