Context Switch

  • AVR ctx_frame needs to be updated to save only args/temp regs
  • RV, AVR callee-saved frame / CSF struct needs to be created
  • CSF switch will result in context switch

TCB

  • TCB will be made part of cpu include files thread.h
  • tcb_t will enclose csf_t and other thread parameters
  • tcb_t will be later called in xxxxx_tcb_t for example current cc_sched_tcb_t which will house other parameters too
  • arch_ctx_sw(tcb_t *old, tcb_t *new) will be part of arch.c in each visors
