In order to choose a suspend to RAM mode, requirements from applications running on co-processors need to be communicated and honored. This talk shall cover how the Linux remoteproc driver should implement the system suspend resume functions that will coordinate with firmware running on a remote core during suspend and resume of the system. This talk will give attendees the understanding of what it takes for a heterogeneous SoC to leverage the remoteproc subsystem to implement graceful suspend and resume of remote cores. We shall also look at the existing state of remoteproc driver in kernel, areas of improvements and optimization, and blockers we are facing in upstreaming suspend resume functionality in the TI’s remoteproc driver.
