2018-02-13remoteproc: qcom: Introduce sysmonBjorn Andersson1-0/+12
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.

2018-02-12remoteproc: qcom: Register segments for core dumpSarangdhar Joshi1-0/+1
Register MDT segments with the remoteproc core dump functionality in order to include them in a core dump, in case of a recovery of the remote processor. Signed-off-by: Sarangdhar Joshi <spjoshi@codeaurora.org> Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org>
2018-02-12soc: qcom: mdt-loader: Return relocation baseBjorn Andersson1-1/+3
In order to implement support for grabbing core dumps in remoteproc it's necessary to know the relocated base of the image, as the offsets from the virtual memory base might not be based on the physical address. Return the adjusted physical base address to the caller. Acked-by: Andy Gross <andy.gross@linaro.org> Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org>
2018-02-12remoteproc: Remove null character write of shared memJitendra Sharma1-3/+0
remoteproc is writing '\0' in the shared mem region. This region is shared among multiple clients that are also trying to read. Hence they miss first character. Remove this null character write, as this mem area is supposed to be Read only. Further during every subsystem reboot, this region is initialized with default, hence no need to write this region.

2018-01-15remoteproc: Drop dangling find_rsc_table dummiesBjorn Andersson1-1/+0
As the core now deals with the lack of a resource table, remove the dangling custom dummy implementations of find_rsc_table from drivers. Reviewed-By: Loic Pallardy <loic.pallardy@st.com> Tested-By: Loic Pallardy <loic.pallardy@st.com> Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org>
2018-01-15remoteproc: Merge rproc_ops and rproc_fw_opsBjorn Andersson1-7/+2
There are currently a few different schemes used for overriding fw_ops or parts of fw_ops. Merge fw_ops into rproc_ops and expose the default ELF-loader symbols so that they can be assigned by the drivers. To keep backwards compatibility with the "default" case, a driver not specifying the "load" operation is assumed to want the full ELF-loader suit of functions.

2017-09-02remoteproc: qcom: adsp: Allow defining GLINK edgeBjorn Andersson1-0/+3
Introduce the GLINK subdev, which allows the definition of a GLINK edge as child of a remoteproc. Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org>

2017-08-02remoteproc: qcom: Add support for SSR notificationsBjorn Andersson1-0/+6
This adds the remoteproc part of subsystem restart, which is responsible for emitting notifications to other processors in the system about a dying remoteproc instance. These notifications are propagated to the various communication systems in the various remote processors to shut down communication links that was left in a dangling state as the remoteproc was stopped (or crashed).

2017-02-06remoteproc: qcom: mdt_loader: Refactor MDT loaderBjorn Andersson1-28/+2
Pushing the SCM calls into the MDT loader reduces duplication in the callers and allows for non-remoteproc clients to use the helper for parsing and loading MDT files. Cc: Andy Gross <andy.gross@linaro.com> Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org>
