2020-07-15remoteproc: qcom_sysmon: Solve function header bitrot issuesLee Jones1-2/+2
Looks as though 'name' has now been moved into 'struct sysmod_event' which is passed in instead. However, the parameter descriptions were not updated at the same time. Let's do that now. Fixes the following W=1 kernel build warning(s): drivers/remoteproc/qcom_sysmon.c:78: warning: Function parameter or member 'event' not described in 'sysmon_send_event' drivers/remoteproc/qcom_sysmon.c:78: warning: Excess function parameter 'name' description in 'sysmon_send_event' drivers/remoteproc/qcom_sysmon.c:350: warning: Function parameter or member 'event' not described in 'ssctl_send_event' drivers/remoteproc/qcom_sysmon.c:350: warning: Excess function parameter 'name' description in 'ssctl_send_event' Cc: Andy Gross <agross@kernel.org> Cc: linux-arm-msm@vger.kernel.org Signed-off-by: Lee Jones <lee.jones@linaro.org> Link: https://lore.kernel.org/r/20200715123551.4011154-2-lee.jones@linaro.org Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org>
2020-04-20remoteproc: sysmon: Inform current rproc about all active rprocsSiddharth Gupta1-0/+25
Clients/services running on a remoteproc that booted up might need to be aware of the state of already running remoteprocs. When a remoteproc boots up (fresh or after recovery) it is not aware of the remoteprocs that booted before it, i.e., the system state is incomplete. So to keep track of it we send sysmon on behalf of all 'ONLINE' remoteprocs.

2020-04-20remoteproc: sysmon: Add notifications for eventsSiddharth Gupta1-0/+37
Add notification for other stages of remoteproc boot and shutdown. This includes adding callback functions for the prepare and unprepare events, and fleshing out the callback function for start.

2020-04-20remoteproc: sysmon: Add ability to send type of notificationSiddharth Gupta1-17/+37
Current implementation of the sysmon driver does not support adding notifications for other remoteproc events - prepare, start, unprepare. Clients on the remoteproc side might be interested in knowing when a remoteproc boots up. This change adds the ability to send the notification type along with the name. For example, audio DSP is interested in knowing when modem has crashed so that it can perform cleanup and wait for modem to boot up before it starts processing data again.

2018-06-26remoteproc: Make client initialize ops in rproc_subdevBjorn Andersson1-1/+4
In preparation of adding the additional prepare and unprepare operations make the client responsible for filling out the function pointers of the rproc_subdev. This makes the arguments to rproc_add_subdev() more manageable, in particular when some of the functions are left out.
