	  Experimental driver for Intel Xe series GPUs

	  If "M" is selected, the module will be called xe.

	  Choose this option to detect DP tunnels and enable the Bandwidth
	  Allocation mode for such tunnels. This allows using the maximum
	  resolution allowed by the link BW on all displays sharing the
	  link BW, for instance on a Thunderbolt link.

	  If in doubt say "Y".

	depends on DRM_XE_GPUSVM
	select GET_FREE_REGION
	default y
	help
	  Disable this option only if you want to compile out without device
	  memory mirror. Will reduce KMD memory footprint when disabled.

config DRM_XE_FORCE_PROBE
	string "Force probe xe for selected Intel hardware IDs"
	depends on DRM_XE
	help
	  This is the default value for the xe.force_probe module
	  parameter. Using the module parameter overrides this option.

	  Force probe the xe for Intel graphics devices that are
	  recognized but not properly supported by this kernel version. It is
	  recommended to upgrade to a kernel version with proper support as soon
	  as it is available.

	  It can also be used to block the probe of recognized and fully
	  supported devices.

	  Use "" to disable force probe. If in doubt, use this.

	  Use "<pci-id>[,<pci-id>,...]" to force probe the xe for listed
	  devices. For example, "4500" or "4500,4571".

	  Use "*" to force probe the driver for all known devices.

	  Use "!" right before the ID to block the probe of the device. For
	  example, "4500,!4571" forces the probe of 4500 and blocks the probe of
	  4571.

	  Use "!*" to block the probe of the driver for all known devices.
