rpmsg: qcom_smd: Correct return value for O_NONBLOCK

2017-01-12T10:39:31Z

commit 1d74e7ed5dc1903ac081574a9b6aa94e7ba4ad45 upstream. qcom_smd_send() should return -EAGAIN for non-blocking channels with insufficient space, so that we can propagate this event to user space.

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.

rpmsg: Allow callback to return errors

2016-09-09T05:15:25Z

Some rpmsg backends support holding on to and redelivering messages upon failed handling of them, so provide a way for the callback to report and error and allow the backends to handle this. Signed-off-by: Bjorn Andersson

rpmsg: Move virtio specifics from public header

2016-09-09T05:15:25Z

Move virtio rpmsg implementation details from the public header file to the virtio rpmsg implementation. Signed-off-by: Bjorn Andersson

rpmsg: virtio: Hide vrp pointer from the public API

2016-09-09T05:15:24Z

Create a container struct virtio_rpmsg_channel around the rpmsg_channel to keep virtio backend information separate from the rpmsg and public API. This makes the public structures independant of virtio. Signed-off-by: Bjorn Andersson

rpmsg: Hide rpmsg indirection tables

2016-09-09T05:15:24Z

Move the device and endpoint indirection tables to the rpmsg internal header file, to hide them from the public API. Signed-off-by: Bjorn Andersson

rpmsg: Split rpmsg core and virtio backend

2016-09-09T05:15:23Z

Extract the generic rpmsg core functionality from the virtio rpmsg implementation, splitting the implementation in a rpmsg core and a virtio backend. Based on initial work by Sricharan R Cc: Sricharan R Signed-off-by: Bjorn Andersson

rpmsg: Split off generic tail of create_channel()

2016-09-09T05:15:23Z

The tail of create_channel() is common among all rpmsg backends, so split it off from the virtio specific part to allow it to be extracted to the rpmsg core. Signed-off-by: Bjorn Andersson

rpmsg: Move helper for finding rpmsg devices to core

2016-09-09T05:15:22Z

Extract and move the helper function for finding rpmsg child devices to the core. Signed-off-by: Bjorn Andersson
