In the good old days when graphics parameters were configured explicitly
|
||||
in a file called xorg.conf, even broken hardware could be managed.
|
||||
|
||||
Today, with the advent of Kernel Mode Setting, a graphics board is
|
||||
either correctly working because all components follow the standards -
|
||||
or the computer is unusable, because the screen remains dark after
|
||||
booting or it displays the wrong area. 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 (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".
|
||||
|
||||
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.
|
||||
|
||||
X11:
|
||||
HTimings: hdisp hsyncstart hsyncend htotal
|
||||
VTimings: vdisp vsyncstart vsyncend vtotal
|
||||
|
||||
EDID:
|
||||
#define XPIX hdisp
|
||||
#define XBLANK htotal-hdisp
|
||||
#define XOFFSET hsyncstart-hdisp
|
||||
#define XPULSE hsyncend-hsyncstart
|
||||
|
||||
#define YPIX vdisp
|
||||
#define YBLANK vtotal-vdisp
|
||||
#define YOFFSET (63+(vsyncstart-vdisp))
|
||||
#define YPULSE (63+(vsyncend-vsyncstart))
|
||||
|
||||
The CRC value in the last line
|
||||
#define CRC 0x55
|
||||
also is a bit tricky. After a first version of the binary data set is
|
||||
created, it must 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.
