Tegra combined UART is a client-server model which allows a server
|
||
|
|
running on SPE to multiplex a single UART controller amongst multiple
|
||
|
|
UART clients.
|
||
|
|
|
||
|
|
This config enables the Linux client driver. Instead of
|
||
|
|
directly bit banging the UART controller, the client driver
|
||
|
|
communicates with the SPE server using mailbox registers. The SPE
|
||
|
|
server multiplexes the UART controller amongst the various clients.
|
||
|
|
This allows all the clients to send output and receive input through a
|
||
|
|
single UART controller.
|
||
|
|
|
||
|
|
Combined-uart uses 'ctrl /' as break-signal for SysRq, for example:
|
||
|
|
'ctrl / + h' for sysrq-help.

Add support for emulating a TTY device over the Tegra Hypervisor interface.

To compile this driver as a module, choose M here: the
|
||
|
|
module will be called tegra_hv_comm.
