**`none`** - Assume there's no i8042 controller in the system.
**`force`** - Assume there's i8042 controller in the system.
* **`i8042_first_port_translation`** - This parameter expects **`on`** or **`off`** and is by default set to **`off`**.
When set to **`off`**, the kernel will not enable first PS2 port translation.
When set to **`on`**, the kernel will enable first PS2 port translation.
* **`panic`** - This parameter expects **`halt`** or **`shutdown`**. This is particularly useful in CI contexts.
* **`pci`** - This parameter expects **`ecam`**, **`io`** or **`none`**. When selecting **`none`**
