As a remedy for such situations, the kernel configuration item
CONFIG_DRM_LOAD_EDID_FIRMWARE was introduced. It allows to provide an
individually prepared or corrected EDID data set in the /lib/firmware
-directory from where it is loaded via the firmware interface. The code
-(see drivers/gpu/drm/drm_edid_load.c) contains built-in data sets for
-commonly used screen resolutions (800x600, 1024x768, 1280x1024, 1600x1200,
-1680x1050, 1920x1080) as binary blobs, but the kernel source tree does
-not contain code to create these data. In order to elucidate the origin
-of the built-in binary EDID blobs and to facilitate the creation of
-individual data for a specific misbehaving monitor, commented sources
-and a Makefile environment are given here.
-
-To create binary EDID and C source code files from the existing data
-material, simply type "make" in tools/edid/.
-
-If you want to create your own EDID file, copy the file 1024x768.S,
-replace the settings with your own data and add a new target to the
-Makefile. Please note that the EDID data structure expects the timing
-values in a different way as compared to the standard X11 format.
