remoteproc: Prevent incorrect rproc state on xfer mem ownership failure

2018-07-03T09:27:06+00:00

commit 2724807f7f70a6a3e67b3f6bf921cc77ed39c8a1 upstream. Any failure in the secure call for transferring mem ownership of mba region to Q6 would result in reporting that the remoteproc device is running. This is because the previous q6v5_clk_enable would have been a success. Prevent this by updating variable 'ret' accordingly.

remoteproc: fix crashed parameter logic on stop call

2018-04-25T23:43:55+00:00

Fix rproc_add_subdev parameter name and inverse the crashed logic. Fixes: 880f5b388252 ("remoteproc: Pass type of shutdown to subdev remove") Reviewed-by: Alex Elder Signed-off-by: Arnaud Pouliquen Signed-off-by: Bjorn Andersson

remoteproc: fix null pointer dereference on glink only platforms

2018-04-06T05:53:16+00:00

Currently calling list_del on smd subdev remove path results in null pointer dereference on glink only platforms. Fix this by adding safety checks in glink/smd subdev remove paths. Signed-off-by: Sibi Sankar Signed-off-by: Bjorn Andersson

soc: qcom: qmi: add CONFIG_NET dependency

remoteproc: imx_rproc: Slightly simplify code in 'imx_rproc_probe()'

2018-03-18T22:43:46+00:00

We can return directly at the beginning of the function and save the 'err' label. We can also explicitly return 0 when the probe succeed. Signed-off-by: Christophe JAILLET Signed-off-by: Bjorn Andersson

remoteproc: imx_rproc: Re-use existing error handling path in 'imx_rproc_probe()'

2018-03-18T22:43:46+00:00

Avoid some code ducplication and be more future-proof. Signed-off-by: Christophe JAILLET Signed-off-by: Bjorn Andersson

remoteproc: imx_rproc: Fix an error handling path in 'imx_rproc_probe()'

2018-03-18T22:43:46+00:00

If 'of_device_get_match_data()' fails, we must undo the previous 'rproc_alloc()' call. Fixes: a0ff4aa6f010 ("remoteproc: imx_rproc: add a NXP/Freescale imx_rproc driver") Signed-off-by: Christophe JAILLET Signed-off-by: Bjorn Andersson

remoteproc: qcom: Introduce sysmon

2018-02-13T00:57:22+00:00

The sysmon client communicates either via a dedicated SMD/GLINK channel or via QMI encoded messages over IPCROUTER with remote processors in order to perform graceful shutdown and inform about other remote processors shutting down. Acked-By: Chris Lew Signed-off-by: Bjorn Andersson

remoteproc: Pass type of shutdown to subdev remove

2018-02-13T00:57:22+00:00

remoteproc instances can be stopped either by invoking shutdown or by an attempt to recover from a crash. For some subdev types it's expected to clean up gracefully during a shutdown, but are unable to do so during a crash - so pass this information to the subdev remove functions.
