Subject: Re: [PATCH v3,0/3] drivers: rpmon: new driver Remote Processor Monitor

Hi Bjorn,
Mainly two aspects:
 - Different message drivers modularly added to support different platforms.
   Currently, RPMON_QMI is available, and further maybe mailbox or so.
 - Different events to be notified and different actions to be taken out.
   Currently, connection check action is available, and remote endpoint's
   registeration event would be notified.

I hope the Remote Porcessor Monitor would eventually do something more
and be used by more users and platforms, and more actions and events
would be added as enhancement. At the same time, it is better to support
different SoC platforms. So I wrote the codes in kernel.

Thanks,
Wenhu
