We can then have the necessary plumbing in the host Linux kernel to either drop the machine into a debugger or trigger a dump capture, if configured. On P9, this would translate to a series of SCOM operations for the SBE It would be good to have a REST API defined to cater to this specific purpose. The API should cater to: - SRESET a core - SRESET a chip - SRESET all cores Thoughts? Regards, Ananth
