---help---
|
|
Say Y if you intend to use Qualcomm IPC router protocol. The
|
|
protocol is used to communicate with services provided by other
|
|
hardware blocks in the system.
|
|
|
|
In order to do service lookups, a userspace daemon is required to
|
|
maintain a service listing.

Say Y here to expose a character device that allows user space to

implement endpoints of QRTR, for purpose of tunneling data to other

|
hosts or testing purposes.

help
|
|
Say Y here to support MHI based ipcrouter channels. MHI is the
|
|
transport used for external modem connections for IPC Router. The
|
|
MHI bus provides an asynchronous send mechanism, the QRTR MHI
|
|
transport will wait for the uplink callback notification before
|
|
returning to qrtr.

help
|
|
Say Y here to support USB based ipcrouter channels. USB transport
|
|
is used for connections with other sytems for IPC Router. The USB
|
|
transport provides bulk endpoints to facilitate sending and receiving
|
|
IPC Router data packets.
|

config QRTR_FIFO

tristate "FIFO IPC Router channels"
|

help
|
|
Say Y here to support FIFO based ipcrouter channels. FIFO Transport
|
|
Layer enables IPC Router communication between two virtual machines.
|
|
The shared memory between virtual machines will be allocated by the
|
|
hypervisor and signal other VMs through virtualized interrupts.
