Linux to MHU communication in Multi chiplet SOC

chandrashekar 6 months ago

let say in a ARM neoverse based Multi chiplet SOC,

Chiplet 0 (primari chiplet with SCP, MCP) has 32 cores, chiplet 1 (secondary chiplet with SCP, MCP) has 32 cores,
If Linux want to enable core 40, (which is in chiplet 1),
how Linux get access to Chiplet 1 MHU, and enable core 40.
