Under normal conditions (when mounting SysFS in /sys), there will be a
new directory in the /sys/devices directory called "graphics".
For now, under that directory there will be only a sub-directory called
"connectors" which will contain all DisplayConnectors' details, each in
its own sub-directory too, distinguished in naming with its minor
number.
Therefore, /sys/devices/graphics/connectors/MINOR_NUMBER/ will contain:
- General device attributes such as mutable_mode_setting_capable,
double_buffering_capable, flush_support, partial_flush_support and
refresh_rate_support. These values are exposed in the ioctl interface
of the DisplayConnector class too, but these can be useful later on
for command line utilities that want/need to expose these basic
settings.
- The EDID blob, simply named "edid". This will help userspace to fetch
the edid without the need of using the ioctl interface later on.
