| config QRTR |
| tristate "Qualcomm IPC Router support" |
| depends on ARCH_QCOM || COMPILE_TEST |
| ---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. |
| |
| if QRTR |
| |
| config QRTR_WAKEUP_MS |
| int "QRTR Wakeup timeout" |
| default 0 |
| help |
| This option is used to configure the wakesource timeout that QRTR |
| should take when a packet is received. The qrtr driver can guarantee |
| that the packet gets queued to the socket but cannot guarantee the |
| client process will get time to run if auto sleep is enabled. This |
| config will help mitigate missed packets on systems where auto sleep |
| is aggressive. |
| |
| config QRTR_SMD |
| tristate "SMD IPC Router channels" |
| depends on RPMSG || (COMPILE_TEST && RPMSG=n) |
| ---help--- |
| Say Y here to support SMD based ipcrouter channels. SMD is the |
| most common transport for IPC Router. |
| |
| config QRTR_TUN |
| tristate "TUN device for Qualcomm IPC Router" |
| ---help--- |
| 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. |
| |
| config QRTR_MHI |
| tristate "MHI IPC Router channels" |
| depends on MHI_BUS || (COMPILE_TEST && MHI_BUS=n) |
| 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. |
| |
| config QRTR_USB |
| tristate "USB IPC Router channels" |
| depends on USB || (COMPILE_TEST && USB=n) |
| 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. |
