Hi,
During the context switch in scheduling, could you please let me know,
where the process/thread's information or state is stored and which
function call is responsible for it?

Thanks,
Subramanian.

Linux uses switch_to, xenomai uses xnarch_switch_to. These are defined
differently for each architecture and may be either macros or functions
depending on the architecture. The registers are loaded and saved from
the task control block.
