617d3293 - rpmsg: Move the rpmsg control device from rpmsg_char to rpmsg_ctrl

Mon, 24 Jan 2022 10:25:16 +0000

rpmsg: Move the rpmsg control device from rpmsg_char to rpmsg_ctrlCreate the rpmsg_ctrl.c module and move the code related to therpmsg_ctrldev device in this new module.Add the dependency between rpmsg_char and rpmsg_ctrl in thekconfig file:1) RPMSG_CTRL can set as module or built-in if RPMSG=y || RPMSG_CHAR=y || RPMSG_CHAR=n2) RPMSG_CTRL can not be set as built-in if RPMSG=m || RPMSG_CHAR=mNote that RPMGH_CHAR and RPMSG_CTRL can be activated separately.Therefore, the RPMSG_CTRL configuration must be set for backwards compatibility.Signed-off-by: Arnaud Pouliquen Signed-off-by: Bjorn Andersson Link: https://lore.kernel.org/r/20220124102524.295783-4-arnaud.pouliquen@foss.st.com List of files: /linux-6.15/drivers/rpmsg/Kconfig

rpmsg: Turn name service into a stand alone driverMake the RPMSG name service announcement a stand alone driver so that itcan be reused by other subsystems. It is also the first step in making thefunctionatlity transport independent, i.e that is not tied to virtIO.Reviewed-by: Guennadi Liakhovetski Tested-by: Guennadi Liakhovetski Co-developed-by: Mathieu Poirier Signed-off-by: Mathieu Poirier Co-developed-by: Guennadi Liakhovetski Signed-off-by: Guennadi Liakhovetski Signed-off-by: Arnaud Pouliquen Link: https://lore.kernel.org/r/20201120214245.172963-9-mathieu.poirier@linaro.orgSigned-off-by: Bjorn Andersson List of files: /linux-6.15/drivers/rpmsg/Kconfig

4d91d7b0 - rpmsg: Allow RPMSG_VIRTIO to be enabled via menuconfig or defconfig

Thu, 05 Oct 2017 16:43:20 +0000

rpmsg: Allow RPMSG_VIRTIO to be enabled via menuconfig or defconfigCurrently, RPMSG_VIRTIO can only be enabled if some other kconfigoption selects it. This does not allow it to be enabled forvirtualized systems where Virtio RPMSG is available over VirtioMMIO or PCI transport.This patch updates RPMSG_VIRTIO kconfig option so that we canenable the VirtIO RPMSG driver via menuconfig or defconfig. Thepatch also removes "select RPMSG_VIRTIO" from various remoteprockconfig options because it is now user selectable.Signed-off-by: Anup Patel Signed-off-by: Bjorn Andersson List of files: /linux-6.15/drivers/rpmsg/Kconfig

rpmsg: glink: Introduce glink smem based transportThe glink protocol supports different types of transports (sharedmemory). With the core protocol remaining the same, the way thetransport's memory is probed and accessed is different.

Tue, 27 Jun 2017 22:46:07 +0000

rpmsg: Drop VIRTUALIZATION dependency from RPMSG_VIRTIOA dependency to VIRTUALIZATION has been added to RPMSG_VIRTIO (backwhen it was named RPMSG) in v3.10 kernel in commit 397944df3290("rpmsg: fix kconfig dependencies for VIRTIO") to resolve Kconfigwarnings due to the inclusion of the virtio configuration file fromthe ARM's KVM config file. The KVM config was fixed properly in thesubsequent release in commit 8bd4ffd6b3a9 ("ARM: kvm: don't includedrivers/virtio/Kconfig"). So, drop this unneeded VIRTUALIZATIONdependency from RPMSG_VIRTIO.Signed-off-by: Suman Anna Signed-off-by: Bjorn Andersson List of files: /linux-6.15/drivers/rpmsg/Kconfig

c0cdc19f - rpmsg: Driver for user space endpoint interface

Wed, 11 Jan 2017 14:35:12 +0000

rpmsg: Driver for user space endpoint interfaceThis driver allows rpmsg instances to expose access to rpmsg endpointsto user space processes. It provides a control interface, allowinguserspace to export endpoints and an endpoint interface for each exposedendpoint.The implementation is based on prior art by Texas Instrument, Google,PetaLogix and was derived from a FreeRTOS performance statistics driverwritten by Michal Simek.The control interface provides a "create endpoint" ioctl, which is fed aname, source and destination address. The three values are used tocreate the endpoint, in a backend-specific way, and a rpmsg endpointdevice is created - with the three parameters are available in sysfs forudev usage.E.g. to create an endpoint device for one of the Qualcomm SMD channelrelated to DIAG one would issue: struct rpmsg_endpoint_info info = { "DIAG_CNTL", 0, 0 }; int fd = open("/dev/rpmsg_ctrl0", O_RDWR); ioctl(fd, RPMSG_CREATE_EPT_IOCTL, &info);Each created endpoint device shows up as an individual character devicein /dev, allowing permission to be controlled on a per-endpoint basis.The rpmsg endpoint will be created and destroyed following the openingand closing of the endpoint device, allowing rpmsg backends to open andclose the physical channel, if supported by the wire protocol.Cc: Marek Novak Cc: Matteo Sartori Cc: Michal Simek Signed-off-by: Bjorn Andersson List of files: /linux-6.15/drivers/rpmsg/Kconfig

rpmsg: smd: fix dependency on QCOM_SMD=nThe ARM allmodconfig build broke with the addition of the SMD rpmsgdriver that conflicts with the driver its replaces:WARNING: drivers/soc/qcom/smd: 'qcom_smd_register_edge' exported twice. Previous export was in drivers/rpmsg/qcom_smd.koWARNING: drivers/soc/qcom/smd: 'qcom_smd_unregister_edge' exported twice. Previous export was in drivers/rpmsg/qcom_smd.koThere is already a dependency that is meant to avoid the brokenconfiguration, but that only prevents the case where at leastone of the two are built-in, but not if both are modules.This changes the dependency to "=n", to ensure that the new drivercan only be enabled if the other one is completely disabled.Signed-off-by: Arnd Bergmann Fixes: 53e2822e56c7 ("rpmsg: Introduce Qualcomm SMD backend")Signed-off-by: Bjorn Andersson List of files: /linux-6.15/drivers/rpmsg/Kconfig
