99412221 - remoteproc: qcom: expose types for COMPILE_TEST

Thu, 07 Jan 2021 23:34:01 +0000

remoteproc: qcom: expose types for COMPILE_TESTStub functions are defined for SSR notifier registration in caseQCOM_RPROC_COMMON is not configured. As a result, code that usesthese functions can link successfully even if the common remoteproccode is not built.Code that registers an SSR notifier function likely needs thetypes defined in "qcom_rproc.h", but those are only exposed ifQCOM_RPROC_COMMON is enabled.Rearrange the conditional definition so the qcom_ssr_notify_datastructure and qcom_ssr_notify_type enumerated type are definedwhether or not QCOM_RPROC_COMMON is enabled.Reviewed-by: Bjorn Andersson Signed-off-by: Alex Elder Signed-off-by: Jakub Kicinski List of files: /linux-6.15/include/linux/remoteproc/qcom_rproc.h

62495d77 - remoteproc: qcom: Add notification types to SSR

Wed, 24 Jun 2020 02:23:28 +0000

remoteproc: qcom: Add notification types to SSRThe SSR subdevice only adds callback for the unprepare event. Add callbacksfor prepare, start and prepare events. The client driver for a particularremoteproc might be interested in knowing the status of the remoteprocwhile undergoing SSR, not just when the remoteproc has finished shuttingdown.Reviewed-by: Alex Elder Signed-off-by: Siddharth Gupta Signed-off-by: Rishabh Bhatnagar Link: https://lore.kernel.org/r/1592965408-16908-3-git-send-email-rishabhb@codeaurora.orgSigned-off-by: Bjorn Andersson List of files: /linux-6.15/include/linux/remoteproc/qcom_rproc.h

5abfe5cf - remoteproc: qcom: Add per subsystem SSR notification

Wed, 24 Jun 2020 02:23:27 +0000

remoteproc: qcom: Add per subsystem SSR notificationCurrently there is a single notification chain which is called whenever anyremoteproc shuts down. This leads to all the listeners being notified, andis not an optimal design as kernel drivers might only be interested inlistening to notifications from a particular remoteproc. Create a globallist of remoteproc notification info data structures. This will hold thename and notifier_list information for a particular remoteproc. The APIto register for notifications will use name argument to retrieve thenotification info data structure and the notifier block will be added tothat data structure's notification chain. Also move from blocking notifierto srcu notifer based implementation to support dynamic notifier headcreation.Reviewed-by: Alex Elder Co-developed-by: Siddharth Gupta Signed-off-by: Siddharth Gupta Signed-off-by: Rishabh Bhatnagar Link: https://lore.kernel.org/r/1592965408-16908-2-git-send-email-rishabhb@codeaurora.orgSigned-off-by: Bjorn Andersson List of files: /linux-6.15/include/linux/remoteproc/qcom_rproc.h

1e140df0 - remoteproc: qcom: Add support for SSR notifications

Tue, 25 Jul 2017 05:56:43 +0000

remoteproc: qcom: Add support for SSR notificationsThis adds the remoteproc part of subsystem restart, which is responsiblefor emitting notifications to other processors in the system about adying remoteproc instance.These notifications are propagated to the various communication systemsin the various remote processors to shut down communication links thatwas left in a dangling state as the remoteproc was stopped (or crashed).Signed-off-by: Bjorn Andersson List of files: /linux-6.15/include/linux/remoteproc/qcom_rproc.h
