Cases when this happens are: +- The graphics board does not recognize the monitor. +- The graphics board is unable to detect any EDID data. +- The graphics board incorrectly forwards EDID data to the driver. +- The monitor sends no or bogus EDID data. +- A KVM sends its own EDID data instead of querying the connected monitor. +Adding the kernel parameter "nomodeset" helps in most cases, but causes +restrictions later on. + +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 (1024x768, 1280x1024, 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". + +If you want to create your own EDID file, copy the file 1024x768.S and +replace the settings with your own data. The CRC value in the last line + #define CRC 0x55 +is a bit tricky. After a first version of the binary data set is +created, it must be be checked with the "edid-decode" utility which will +most probably complain about a wrong CRC. Fortunately, the utility also +displays the correct CRC which must then be inserted into the source +file. After the make procedure is repeated, the EDID data set is ready +to be used. diff --git a/Documentation/EDID/Makefile b/Documentation/EDID/Makefile new file mode 100644 index 0000000..17763ca --- /dev/null +++ b/Documentation/EDID/Makefile @@ -0,0 +1,26 @@ + +SOURCES := $(wildcard [0-9]*x[0-9]*.S) + +BIN := $(patsubst %.S, %.bin, $(SOURCES)) + +IHEX := $(patsubst %.S, %.bin.ihex, $(SOURCES)) + +CODE := $(patsubst %.S, %.c, $(SOURCES)) + +all: $(BIN) $(IHEX) $(CODE) + +clean: + @rm -f *.o *.bin.ihex *.bin *.c + +%.o: %.S + @cc -c $^ + +%.bin: %.o + @objcopy -Obinary $^ $@ + +%.bin.ihex: %.o + @objcopy -Oihex $^ $@ + @dos2unix $@ 2>/dev/null + +%.c: %.bin + @echo "{" >$@; hexdump -f hex $^ >>$@; echo "};" >>$@ diff --git a/Documentation/EDID/edid.S b/Documentation/EDID/edid.S new file mode 100644 index 0000000..ea97ae2 --- /dev/null +++ b/Documentation/EDID/edid.S @@ -0,0 +1,261 @@ +/* + edid.S: EDID data template + + Copyright (C) 2012 Carsten Emde <C.Emde@osadl.org> + + This program is free software; you can redistribute it and/or + modify it under the terms of the GNU General Public License + as published by the Free Software Foundation; either version 2 + of the License, or (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
