rpmsg: virtio_rpmsg_bus: fix channel creation

2016-12-30T11:12:11Z

Since commit 4dffed5b3ac796b ("rpmsg: Name rpmsg devices based on channel id"), it is no more possible for a firmware to register twice a service (on different endpoints). rpmsg_register_device function is failing when calling device_add for the second time as second device has the same name as first one already register. It is because name is based only on service name and so is not more unique. Previously name was unique thanks to the use of rpmsg_dev_index. This patch adds destination and source endpoint numbers device name to create an unique identifier.

rpmsg: qcom_smd: Correct return value for O_NONBLOCK

2016-12-08T15:58:05Z

qcom_smd_send() should return -EAGAIN for non-blocking channels with insufficient space, so that we can propagate this event to user space. Fixes: 53e2822e56c7 ("rpmsg: Introduce Qualcomm SMD backend") Signed-off-by: Bjorn Andersson

rpmsg: smd: Expose edge registration functions

2016-11-15T05:52:14Z

The edge registration functions is to be used from a remoteproc driver to register and unregister an edge as the remote processor comes and goes. Signed-off-by: Bjorn Andersson

rpmsg: Handle invalid parameters in public API

2016-10-31T22:44:57Z

There are two cases of possible uninitialized pointer usage in the API, either the parameters themselves are invalid or we're trying to jump to functions not required to be implemented by all backends. Suggested-by: Loic Pallardy Signed-off-by: Bjorn Andersson

rpmsg: Support drivers without primary endpoint

2016-10-31T22:41:55Z

Some types of rpmsg drivers does not have a primary endpoint to tie their existence upon, but wishes to create and destroy endpoints dynamically, e.g. based on user interactions. Allow rpmsg drivers to omit a driver callback to signal this case and make the probe path not create a primary endpoint in this case. Signed-off-by: Bjorn Andersson

rpmsg: Introduce a driver override mechanism

2016-10-31T22:41:46Z

Similar to other subsystems it's useful to provide a mechanism to force a specific driver match on a device, so introduce this. Signed-off-by: Bjorn Andersson

rpmsg: smd: Reduce restrictions when finding channel

2016-10-31T22:40:40Z

SMD channels are created by the remotes in "opening" state, but sometimes as we close and try to reopen them they linger in closing state. Following the search for a matching channel the create_ept() will verify that the channel is in a suitable state, so we can lax the restrictions of the search function to work around above difference in behaviour.

rpmsg: smd: fix dependency on QCOM_SMD=n

2016-09-12T14:05:13Z

The ARM allmodconfig build broke with the addition of the SMD rpmsg driver 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.ko WARNING: drivers/soc/qcom/smd: 'qcom_smd_unregister_edge' exported twice. Previous export was in drivers/rpmsg/qcom_smd.ko There is already a dependency that is meant to avoid the broken configuration, but that only prevents the case where at least one of the two are built-in, but not if both are modules. This changes the dependency to "=n", to ensure that the new driver can only be enabled if the other one is completely disabled.

rpmsg: Introduce Qualcomm SMD backend

2016-09-09T05:15:26Z

This introduces a new rpmsg backend for the Qualcomm SMD system, allowing communication with various remote processors found in Qualcomm platforms. The implementation is based on, and intends to replace, drivers/soc/qcom/smd.c with the necessary adaptions for fitting with the rpmsg core.
