108	  This is the default value for the xe.force_probe module
109	  parameter. Using the module parameter overrides this option.
110
111	  Force probe the xe for Intel graphics devices that are
112	  recognized but not properly supported by this kernel version. It is
113	  recommended to upgrade to a kernel version with proper support as soon
114	  as it is available.
115
116	  It can also be used to block the probe of recognized and fully
117	  supported devices.
118
119	  Use "" to disable force probe. If in doubt, use this.
120
121	  Use "<pci-id>[,<pci-id>,...]" to force probe the xe for listed
122	  devices. For example, "4500" or "4500,4571".
123
124	  Use "*" to force probe the driver for all known devices.
125
126	  Use "!" right before the ID to block the probe of the device. For
127	  example, "4500,!4571" forces the probe of 4500 and blocks the probe of
128	  4571.
129
130	  Use "!*" to block the probe of the driver for all known devices.
