|
|
* as described by the firm_event structure.
|
|
* - If wskbd support is compiled in and a wskbd driver has been
|
|
* attached then the data is sent to it. Wskbd in turn may
|
|
* - Send the data in the wscons_event form to a process that
|
|
* has opened /dev/wskbd0
|
|
* - Feed the data to a virtual terminal.
|
