Adding adaption/glue layer where the I2C host adapter (Synopsys DesignWare I2C adapter) and the I2C clients (the microcontroller units) are enumerated. The microcontroller units (MCU) that are attached to the GPU depend on the OEM. The initially supported MCU will be the Add-In Management Controller (AMC). Co-developed-by: Michael J.

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.
