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. |
