* net: qrtr: combine nameservice into main moduleLuca Weiss2021-09-281-1/+2
| | | | | | | | | | | | | | | Previously with CONFIG_QRTR=m a separate ns.ko would be built which wasn't done on purpose and should be included in qrtr.ko. Rename qrtr.c to af_qrtr.c so we can build a qrtr.ko with both af_qrtr.c and ns.c.

* net: qrtr: Add MHI transport layerManivannan Sadhasivam2020-05-071-0/+2
| | | | | | | | | | MHI is the transport layer used for communicating to the external modems. Hence, this commit adds MHI transport layer support to QRTR for transferring the QMI messages over IPC Router.

* net: qrtr: Migrate nameservice to kernel from userspaceManivannan Sadhasivam2020-02-211-1/+1
| | | | | | | | | | | | | The QRTR nameservice has been maintained in userspace for some time. This commit migrates it to Linux kernel. This change is required in order to eliminate the need of starting a userspace daemon for making the WiFi functional for ath11k based devices. Since the QRTR NS is not usually packed in most of the distros, users need to clone, build and install it to get the WiFi working. It will become a hassle when the user doesn't have any other source of network connectivity. Signed-off-by: Manivannan Sadhasivam <manivannan.sadhasivam@linaro.org> Signed-off-by: David S.

* net: qrtr: Expose tunneling endpoint to user spaceBjorn Andersson2018-04-271-0/+2
| | | | | | | | | | | | This implements a misc character device named "qrtr-tun" for the purpose of allowing user space applications to implement endpoints in the qrtr network. This allows more advanced (and dynamic) testing of the qrtr code as well as opens up the ability of tunneling qrtr over a network or USB link.

* net: qrtr: fix build problemsArnd Bergmann2016-05-161-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Having multiple loadable modules with the same name cannot work with modprobe, and having both net/qrtr/smd.ko and drivers/soc/qcom/smd.ko results in a (somewhat cryptic) build error: ERROR: "qcom_smd_driver_unregister" [net/qrtr/smd.ko] undefined! ERROR: "qcom_smd_driver_register" [net/qrtr/smd.ko] undefined! ERROR: "qcom_smd_set_drvdata" [net/qrtr/smd.ko] undefined! ERROR: "qcom_smd_send" [net/qrtr/smd.ko] undefined! ERROR: "qcom_smd_get_drvdata" [net/qrtr/smd.ko] undefined! ERROR: "qcom_smd_driver_unregister" [drivers/soc/qcom/wcnss_ctrl.ko] undefined! ERROR: "qcom_smd_driver_register" [drivers/soc/qcom/wcnss_ctrl.ko] undefined! ERROR: "qcom_smd_set_drvdata" [drivers/soc/qcom/wcnss_ctrl.ko] undefined! ERROR: "qcom_smd_send" [drivers/soc/qcom/wcnss_ctrl.ko] undefined! ERROR: "qcom_smd_get_drvdata" [drivers/soc/qcom/wcnss_ctrl.ko] undefined! Also, the qrtr driver uses the SMD interface and has a Kconfig dependency, but also allows for compile-testing when SMD is disabled. However, if with QCOM_SMD=m and COMPILE_TEST=y we can end up with QRTR_SMD=y and that fails with a related link error. The changes the dependency so we can still compile-test the driver but not have it built-in if SMD is a module, to avoid running in the broken configuration, and changes the Makefile to provide the driver under a different module name.
